Chapter 1: Introduction
In this user’s manual, it will not only tell you how to install and connect your network
system but configure and monitor the 24+2 Gigabit L2 plus Switch through the built-in CLI
and web by RS-232 serial interface and Ethernet ports step-by-step. Many explanations in
detail of hardware and software functions are shown as well as the examples of the
operation for web-based interface and command-line interface (CLI).
1.1 Overview
The 24+2-port Gigabit L2 Managed Switch, is a standard switch that meets all IEEE
802.3/u/x/z Gigabit, Fast Ethernet specifications. The switch included 24-Port
10/100/1000Mbps TP (20-Port for TP; 4-Port for Combo) and 2-Port Dual-SFP Fiber
management Ethernet switch.
The switch can be managed through RS-232 serial port via directly connection, or through
Ethernet port using CLI or Web-based management unit, associated with SNMP agent.
With the SNMP agent, the network administrator can logon the switch to monitor,
configure and control each port’s activity in a friendly way. The overall network
management is enhanced and the network efficiency is also improved to accommodate high
bandwidth applications. In addition, the switch features comprehensive and useful function
such as ACL, IP-MAC Binding, DHCP Option 82, QoS (Quality of Service), Spanning
Tree, VLAN, Port Trunking, Bandwidth Control, Port Security, SNMP/RMON, IGMP
Snooping capability via the intelligent software. It is suitable for both metro-LAN and
office application.
In this switch, Port 21 and Port 24 include two types of media --- TP and SFP Fiber (LC,
BiDi LC…); this port supports 10/100/1000Mbps TP or 1000Mbps SFP Fiber with
auto-detected function. 1000Mbps SFP Fiber transceiver is used for high-speed connection
expansion.

10/100/1000Mbps TP is a standard Ethernet port that meets all IEEE 802.3/u/x/z Gigabit,
Fast Ethernet specifications. 1000Mbps SFP Fiber transceiver is a Gigabit Ethernet port
that fully complies with all IEEE 802.3z and 1000Base-SX/LX standards.
1000Mbps Single Fiber WDM (BiDi) transceiver is designed with an optic Wavelength
Division Multiplexing (WDM) technology that transports bi-directional full duplex signal
over a single fiber simultaneously.
For upgrading firmware, please refer to the Section 2.5.2 for more details. The switch will
not stop operating while upgrading firmware and after that, the configuration keeps
unchanged.
VigorSwitch P2261 User’s Guide

Below shows key features of this device:
QoS
Support Quality of Service by the IEEE 802.1P standard. There are two priority queue and
packet transmission schedule.
Spanning Tree
Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree Protocol) standards.
VLAN
Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 256 active VLANs and
VLAN ID 1~4094.
Port Trunking
Support static port trunking and port trunking with IEEE 802.3ad LACP.
Bandwidth Control
Support ingress and egress per port bandwidth control.
Port Security
Support allowed, denied forwarding and port security with MAC address.
SNMP/RMON
SNMP agent and RMON MIB. In the device, SNMP agent is a client software which is
operating over SNMP protocol used to receive the command from SNMP manager (server
site) and echo the corresponded data, i.e. MIB object. Besides, SNMP agent will actively
issue TRAP information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of the SNMP
MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON MIB (RFC
1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643), Ethernet MIB (RFC 1643)
and so on.
IGMP Snooping
Support IGMP version 2 (RFC 2236): The function IGMP snooping is used to establish the
multicast groups to forward the multicast packet to the member ports, and, in nature, avoid
wasting the bandwidth while IP multicast packets are running over the network.
IGMP Proxy
The implementation of IP multicast processing. The switch supports IGMP version 1 and
IGMP version 2, efficient use of network bandwidth, and fast response time for channel
changing. IGMP version 1 (IGMPv1) is described in RFC1112, and IGMP version 2
(IGMPv2) is described in RFC 2236. Hosts interact with the system through the exchange
of IGMP messages. Similarly, when you configure IGMP proxy, the system interacts with
the router on its upstream interface through the exchange of IGMP messages. However,
when acting as the proxy, the system performs the host portion of the IGMP task on the
upstream interface as follows:
¾
2
When queried, sends group membership reports to the group.
VigorSwitch P2261 User’s Guide
¾
When one of its hosts joins a multicast address group to which none of its other hosts
belong, sends unsolicited group membership reports to that group.
¾
When the last of its hosts in a particular multicast group leaves the group, sends an
unsolicited leave group membership report to the all-routers group (244.0.0.2).

2.
Slide the module along the slot. Also be sure that the module is properly seated against
the slot socket/connector
3.
Install the media cable for network connection
4.
Repeat the above steps, as needed, for each module to be installed into slot(s)
5.
Have the power ON after the above procedures are done
TP Port and Cable Installation
In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of cable,
straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in 10/100M TP; 1, 2,
3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and crossed-over (Cable pin-outs for
RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used. It means you do not have to tell from them,
just plug it.
6
1.
Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the other
end is connected to a network-aware device such as a workstation or a server.
2.
Repeat the above steps, as needed, for each RJ-45 port to be connected to a Gigabit
10/100/1000 TP device.
3.
Now, you can start having the switch in operation.
VigorSwitch P2261 User’s Guide
Power On
The switch supports 100-240 VAC, 50-60 Hz power supply. The power supply will
automatically convert the local AC power source to DC power. It does not matter whether
any connection plugged into the switch or not when power on, even modules as well. After
the power is on, all LED indicators will light up immediately and then all off except the
power LED still keeps on. This represents a reset of the system.
Firmware Loading
After resetting, the bootloader will load the firmware into the memory. It will take about 30
seconds, after that, the switch will flash all the LED once and automatically performs
self-test and is in ready state.
1.5.2 Installing Optional SFP Fiber Transceivers to the switch
If you have no modules, please skip this section.
1.5.3 Installing Chassis to a 19-Inch Wiring Closet Rail
Caution: Allow a proper spacing and proper air ventilation for the cooling fan at both
sides of the chassis.
1.
Wear a grounding device for electrostatic discharge.
2.
Screw the mounting accessory to the front side of the switch.
3.
Place the Chassis into the 19-inch wiring closet rail and locate it at the proper position.
Then, fix the Chassis by screwing it.

1.5.4 Cabling Requirements
To help ensure a successful installation and keep the network performance good, please
take a care on the cabling requirement. Cables with worse specification will render the
LAN to work poorly.
Cabling Requirements for TP Ports
For Fast Ethernet TP network connection
¾
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100
meters.
Gigabit Ethernet TP network connection
¾
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100
meters. Cat. 5e is recommended.
Cabling Requirements for SFP Module
It is more complex and comprehensive contrast to TP cabling in the fiber media. Basically,
there are two categories of fiber, multi mode (MM) and single mode (SM). The later is
categorized into several classes by the distance it supports. They are SX, LX, LHX, XD,
and ZX. From the viewpoint of connector type, there mainly are LC and BIDI LC.

Switch Cascading in Topology
Takes the Delay Time into Account
Theoretically, the switch partitions the collision domain for each port in switch cascading
that you may up-link the switches unlimitedly. In practice, the network extension
(cascading levels & overall diameter) must follow the constraint of the IEEE
8
VigorSwitch P2261 User’s Guide
802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations
are the timing requirement from physical signals defined by 802.3 series specification of
Media Access Control (MAC) and PHY, and timer from some OSI layer 2 protocols such
as 802.1d, 802.1q, LACP and so on.
The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:
1000Base-X TP, Fiber
Round trip Delay: 4096
100Base-TX TP/100Base-FX Fiber
Round trip Delay: 512
Cat. 5 TP Wire:

Bit Time unit: 1ns (1sec./1000 Mega bit)
1.12/m
Fiber Cable:
1.0/m
Bit Time unit: 0.01μs (1sec./100 Mega bit)
Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices must be
within Round Trip Delay (bit times) in a half-duplex network segment (collision domain).
For full-duplex operation, this will not be applied. You may use the TP-Fiber module to
extend the TP node distance over fiber optic and provide the long haul connection.
Typical Network Topology in Deployment
A hierarchical network with minimum levels of switch may reduce the timing delay
between server and client station. Basically, with this approach, it will minimize the
number of switches in any one path; will lower the possibility of network loop and will
improve network efficiency. If more than two switches are connected in the same network,
select one switch as Level 1 switch and connect all other switches to it at Level 2.
Server/Host is recommended to connect to the Level 1 switch. This is general if no VLAN
or other special requirements are applied.
Case 1: All switch ports are in the same local area network.
Every port can access each other.
If VLAN is enabled and configured, each node in the network that can communicate each
other directly is bounded in the same VLAN area.
Here VLAN area is defined by what VLAN you are using. The switch supports both
port-based VLAN and tag-based VLAN. They are different in practical deployment,
especially in physical location. The following diagram shows how it works and what the
difference they are.
VigorSwitch P2261 User’s Guide

Case 2: Port-based VLAN -1
The same VLAN members could not be in different switches.
Every VLAN members could not access VLAN members each other.
The switch manager has to assign different names for each VLAN groups
at one switch.
Case 3: Port-based VLAN – 2
VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members.
VLAN2 members could not access VLAN1 and VLAN3 members, but they could access
VLAN4 members.
VLAN3 members could not access VLAN1, VLAN2 and VLAN4.
VLAN4 members could not access VLAN1 and VLAN3 members, but they could
access VLAN2 members.

1.5.5 Configuring the Management Agent of Switch
Managing VigorSwitch P2261 through Ethernet Port
Before you communicate with the switch, you have to finish the
configuration of the IP address or to know the IP address of the switch. Then, follow the
procedures listed below.
1.
Set up a physical path between the configured the switch and a PC by a qualified UTP
Cat. 5 cable with RJ-45 connector.
Note: If PC directly connects to the switch, you have to setup the same subnet
mask between them. But, subnet mask may be different for the PC in the remote
site.
2.
12
Run web browser and follow the menu. Please refer to Chapter 2.
VigorSwitch P2261 User’s Guide
1.5.6 IP Address Assignment
For IP address configuration, there are three parameters needed to be filled in. They are IP
address, Subnet Mask, Default Gateway and DNS.
IP address:
The address of the network device in the network is used for internetworking
communication. Its address structure looks is shown below. It is “classful” because it is
split into predefined address classes or categories.
Each class has its own network range between the network identifier and host identifier in
the 32 bits address. Each IP address comprises two parts: network identifier (address) and
host identifier (address). The former indicates the network where the addressed host resides,
and the latter indicates the individual host in the network which the address of host refers to.
And the host identifier must be unique in the same LAN. Here the term of IP address we
used is version 4, known as IPv4.
32 bits
Network identifier
Host identifier
With the classful addressing, it divides IP address into three classes, class A, class B and
class C. The rest of IP addresses are for multicast and broadcast. The bit length of the
network prefix is the same as that of the subnet mask and is denoted as IP address/X, for
example, 192.168.1.0/24. Each class has its address range described below.
Class A:
Address is less than 126.255.255.255. There are a total of 126 networks can be defined
because the address 0.0.0.0 is reserved for default route and 127.0.0.0/8 is reserved for
loopback function.
Class B:
IP address range between 128.0.0.0 and 191.255.255.255. Each class B network has a
16-bit network prefix followed 16-bit host address. There are 16,384 (2^14)/16 networks
able to be defined with a maximum of 65534 (2^16 –2) hosts per network.
Class C:
IP address range between 192.0.0.0 and 223.255.255.255. Each class C network has a
24-bit network prefix followed 8-bit host address. There are 2,097,152 (2^21)/24 networks
able to be defined with a maximum of 254 (2^8 –2) hosts per network.
VigorSwitch P2261 User’s Guide
13
Class D and E:
Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP
Multicast. See also RFC 1112. Class E is a class with first 4 MSB set to 1-1-1-1 and is used
for IP broadcast.
According to IANA (Internet Assigned Numbers Authority), there are three specific IP
address blocks reserved and able to be used for extending internal network. We call it
Private IP address and list below:
Class A
10.0.0.0 --- 10.255.255.255
Class B
172.16.0.0 --- 172.31.255.255
Class C
192.168.0.0 --- 192.168.255.255
Please refer to RFC 1597 and RFC 1466 for more information.
Subnet mask:
It means the sub-division of a class-based network or a CIDR block. The subnet is used to
determine how to split an IP address to the network prefix and the host address in bitwise
basis. It is designed to utilize IP address more efficiently and ease to manage IP network.
For a class B network, 128.1.2.3, it may have a subnet mask 255.255.0.0 in default, in
which the first two bytes is with all 1s. This means more than 60 thousands of nodes in flat
IP address will be at the same network. It’s too large to manage practically. Now if we
divide it into smaller network by extending network prefix from 16 bits to, say 24 bits,
that’s using its third byte to subnet this class B network. Now it has a subnet mask
255.255.255.0, in which each bit of the first three bytes is 1. It’s now clear that the first two
bytes is used to identify the class B network, the third byte is used to identify the subnet
within this class B network and, of course, the last byte is the host number.
Not all IP address is available in the sub-netted network. Two special addresses are
reserved. They are the addresses with all zero’s and all one’s host number. For example, an
IP address 128.1.2.128, what IP address reserved will be looked like? All 0s mean the
network itself, and all 1s mean IP broadcast.
14
VigorSwitch P2261 User’s Guide
In this diagram, you can see the subnet mask with 25-bit long, 255.255.255.128, contains
126 members in the sub-netted network. Another is that the length of network prefix equals
the number of the bit with 1s in that subnet mask. With this, you can easily count the
number of IP addresses matched. The following table shows the result.

According to the scheme above, a subnet mask 255.255.255.0 will partition a network with
the class C. It means there will have a maximum of 254 effective nodes existed in this
sub-netted network and is considered a physical network in an autonomous network. So it
owns a network IP address which may looks like 168.1.2.0.
With the subnet mask, a bigger network can be cut into small pieces of network. If we want
to have more than two independent networks in a worknet, a partition to the network must
be performed. In this case, subnet mask must be applied.
For different network applications, the subnet mask may look like 255.255.255.240. This
means it is a small network accommodating a maximum of 15 nodes in the network.
Default gateway:
For the routed packet, if the destination is not in the routing table, all the traffic is put into
the device with the designated IP address, known as default router. Basically, it is a routing
policy. The gateway setting is used for Trap Events Host only in the switch.
For assigning an IP address to the switch, you just have to check what the IP address of the
network will be connected with the switch. Use the same network address and append your
host address to it.
VigorSwitch P2261 User’s Guide
15
First, IP Address: as shown above, enter “192.168.1.226”, for instance. For sure, an IP
address such as 192.168.1.x must be set on your PC.
Second, Subnet Mask: as shown above, enter “255.255.255.0”. Any subnet mask such as
255.255.255.x is allowable in this case.
DNS:
The Domain Name Server translates human readable machine name to IP address. Every
machine on the Internet has a unique IP address. A server generally has a static IP address.
To connect to a server, the client needs to know the IP of the server. However, user
generally uses the name to connect to the server. Thus, the switch DNS client program
(such as a browser) will ask the DNS to resolve the IP address of the named server.

Chapter 2: Operation of
Web-based Management
This chapter instructs you how to configure and manage the switch through the web user
interface it supports, to access and manage the switch. With this facility, you can easily
access and monitor through any one port of the switch all the status of the switch, including
MIBs status, each port activity, Spanning tree status, port aggregation status, multicast
traffic, VLAN and priority status, even illegal access record and so on.
The default values of the managed switch are listed in the table below:

After the managed switch has been finished configuration in the CLI via the switch’s serial
interface, you can browse it. For example, type http://192.168.1.1 in the address row in a
browser, it will show the following screen (see Figure below) and ask you inputting
username and password in order to login and access authentication. The default username
and password are both “admin”. For the first time to use, please enter the default username
and password, then click the <Login> button. The login process now is completed.
In this login menu, you have to input the complete username and password respectively,
the switch will not give you a shortcut to username automatically. This looks inconvenient,
but safer.
In the switch, it supports a simple user management function allowing only one
administrator to configure the system at the same time. If there are two or more users using
administrator’s identity, the switch will allow the only one who logins first to configure the
system. The rest of users, even with administrator’s identity, can only monitor the system.
For those who have no administrator’s identity, can only monitor the system. There are
only a maximum of three users able to login simultaneously in the switch.
To optimize the display effect, we recommend you use Microsoft IE 6.0 above, Netscape
V7.1 above or FireFox V1.00 above and have the resolution 1024x768. The switch
supported neutral web browser interface.
Note: When you login the switch WEB/CLI to manager, you must type the Username and
password first.
Note: The default IP of the switch 192.168.1.226.
Note: When you login P2261 switch Web UI management, you can use both IPv4 and IPv6
login for management.

to the starting date and the ending date. For example, if you
set the day light saving to be 1 hour. When the time passes
over the starting time, the system time will be increased
one hour after one minute at the time since it passed over.
VigorSwitch P2261 User’s Guide
25
And when the time passes over the ending time, the system
time will be decreased one hour after one minute at the
time since it passed over.
The switch supports valid configurable day light saving
time is –5 ~ +5 step one hour. The zero for this parameter
means it need not have to adjust current time, equivalent to
in-act daylight saving. You don’t have to set the
starting/ending date as well. If you set daylight saving to be
non-zero, you have to set the starting/ending date as well;
otherwise, the daylight saving function will not be
activated.
Default for Daylight Saving: 0.
The following parameters are configurable for the function
Daylight Saving and described in detail.

NTP Configuration
NTP is Network Time Protocol and is used to sync the
network time based Greenwich Mean Time (GMT). If use
the NTP mode and select a built-in NTP time server or
manually specify an user-defined NTP server as well as
Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time
automatically, NTP does not update the time periodically
without user’s processing.
Time Zone is an offset time off GMT. You have to select
the time zone first and then perform time sync via NTP
because the switch will combine this time zone offset and
updated NTP time to come out the local time, otherwise,
you will not able to get the correct time. The switch
supports configurable time zone from –12 to +13 step 1
hour.
Default Time zone: +8 Hrs.

2.2.7 IP Configuration – IPv4
IP is an acronym for Internet Protocol. It is a protocol used for communicating data across
an internet network.
IP is a "best effort" system, which means that no packet of information sent over is assured
to reach its destination in the same condition it was sent. Each device connected to a Local
Area Network (LAN) or Wide Area Network (WAN) is given an Internet Protocol address,
and this IP address is used to identify the device uniquely among all other devices
connected to the extended network.
The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol
addresses allowing for in excess of four billion unique addresses. This number is reduced
drastically by the practice of webmasters taking addresses in large blocks, the bulk of
which remain unused. There is a rather substantial movement to adopt a new version of the
Internet Protocol, IPv6, which would have 128-bits Internet Protocol addresses. This
number can be represented roughly by a three with thirty-nine zeroes after it. However,
IPv4 is still the protocol of choice for most of the Internet.
Function name:
IPv4
Function description:
The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To

2.2.9 Port – General Setup
Port configuration is applied to change the setting of each port. In this configuration
function, you can set/reset the following functions. All of them are described in detail
below.
Function name:
General Setup
Function description:
It describes how to view the current port configuration and how to configure ports to
non-default settings, including Linkup/Linkdown, Speed (Current and Type), Flow Control
(Current Rx, Current Tx and Enabled), Maximum Frame Size, Excessive Collision Mode
and Power Control.
Parameter description:
32
Port
This is the logical port number for this row.
Description
It describes to configure the Port’s alias or any descriptions
for the Port Identity. It provides user to write down an
alphanumeric string describing the full name and version
identification for the system’s hardware type, software
version, and networking application
Link
The current link state is displayed graphically. Green
indicates the link is up and red that it is down.
Speed
Current - Provides the current link speed of the port.
Type - Set the speed and duplex of the port. In speed, if the
VigorSwitch P2261 User’s Guide
media is 1Gbps fiber, it is always 1000Mbps and the
duplex is full only. If the media is TP, the Speed/Duplex is
comprised of the combination of speed mode,
10/100/1000Mbps, and duplex mode, full duplex and half
duplex. The following table summarized the function the
media supports.
In Auto mode, no default value. In Forced mode, default
value depends on your setting.
Flow Control
When Auto Speed is selected on a port, this section
indicates the flow control capability that is advertised to
the link partner. When a fixed-speed setting is selected, that
is what is used. The Current Rx column indicates whether
pause frames on the port are obeyed, and the Current Tx
column indicates whether pause frames on the port are
transmitted. The Rx and Tx settings are determined by the
result of the last Auto-Negotiation.
Check the configured column to use flow control. This
setting is related to the setting for Configured Link Speed.
Maximum Frame Size
This module offers 1518~9600 (Bytes) length to make the
long packet.
Excessive Collision Mode
There are two modes to choose when excessive collision
happened in half-duplex condition as below:
Discard - The “Discard” mode determines whether the
MAC drop frames after an excessive collision has
occurred. If yes, a frame is dropped after excessive
collision. This is IEEE Standard 802.3 half-duplex flow
control operation.
Restart: - The “Restart” mode determines whether the
MAC retransmits frames after an excessive collision has
occurred. If set, a frame is not dropped after excessive
collisions, but the backoff sequence is restarted. This is a
violation of IEEE Standard 802.3, but is useful in
non-dropping half-duplex flow control operation.
Power Control
The Usage column shows the current percentage of the
power consumption per port. The Configured column
allows for changing the power savings mode parameters
per port.
Disabled: All power savings mechanisms disabled.
ActiPHY: Link down power savings enabled.
PerfectReach: Link up power savings enabled.

2.2.14 Port - EEE
EEE is a power saving option that reduces the power usage when there is very low traffic
utilization (or no traffic). EEE works by powering down circuits when there is no traffic.
When a port gets data to be transmitted all circuits are powered up. The time it takes to
power up the circuits is named wakeup time. The default wakeup time is 17 us for 1Gbit
links and 30 us for other link speeds. EEE devices must agree upon the value of the wakeup
time in order to make sure that both the receiving and transmitting device has all circuits
powered up when traffic is transmitted. The devices can exchange information about the
devices wakeup time using the LLDP protocol.
For maximizing the power saving, the circuit isn't started at once transmit data are ready for
a port, but is instead queued until 3000 bytes of data are ready to be transmitted. For not
introducing a large delay in case that data less then 3000 bytes shall be transmitted, data are
always transmitted after 48 us, giving a maximum latency of 48 us + the wakeup time.
If desired it is possible to minimize the latency for specific frames, by mapping the frames
to a specific queue (done with QOS), and then mark the queue as an urgent queue. When
an urgent queue gets data to be transmitted, the circuits will be powered up at once and the
latency will be reduced to the wakeup time.
Function name:
EEE

The section allows the user to inspect and configure the current EEE port settings.

Currently we support one sFlow instance on each port due
to hardware limitation.
Sampler Type
Sampler type on the port can be one of the following types:
None, RX,TX, ALL.If type is "none" then the sampling rate
is 0 and no other value is accepted.The default value is
"none".
Sampling Rate
Determines the rate at which samples must be taken on the
ports. If sampling rate is configured as 'N',1/N frames is
sampled.
The sampling rate ranges from 0 to 4095.
Default value is "0" meaning sampling is disabled on the
port.
If receiver time_out is 0sec, this sFlow configuration is
disabled operationally.

2.3.1 Aggregation – Static Trunk
The Aggregation Configuration is used to configure the settings of Link Aggregation. You
can bundle more than one port with the same speed, full duplex and the same MAC to be a
single logical port, thus the logical port aggregates the bandwidth of these ports. This
means you can apply your current Ethernet equipments to build the bandwidth aggregation.
Function name:
Aggregation – Static Trunk
Function description:
Ports using Static Trunk as their trunk method can choose their unique Static GroupID to
form a logic “trunked port”. The benefit of using Static Trunk method is that a port can
immediately become a member of a trunk group without any handshaking with its peer port.
This is also a disadvantage because the peer ports of your static trunk group may not know
that they should be aggregate together to form a “logic trunked port”. Using Static Trunk
on both end of a link is strongly recommended. Please also note that low speed links will
stay in “not ready” state when using static trunk to aggregate with high speed links.

2.3.2 Aggregation – LACP – General Setup
Ports using Link Aggregation Control Protocol (according to IEEE 802.3ad specification)
as their trunking method can choose their unique LACP GroupID to form a logic “trunked
port”. The benefit of using LACP is that a port makes an agreement with its peer port
before it becomes a ready member of a “trunk group” (also called aggregator). LACP is
safer than the other trunking method - static trunk.
Function name:

2.3.5 Spanning Tree – Bridge Settings
The Spanning Tree Protocol (STP) can be used to detect and disable network loops, and to
provide backup links between switches, bridges or routers. This allows the switch to
interact with other bridging devices (that is, an STP-compliant switch, bridge or router) in
your network to ensure that only one route exists between any two stations on the network,
and provide backup links which automatically take over when a primary link goes down.
STP - STP uses a distributed algorithm to select a bridging device (STP- compliant switch,
bridge or router) that serves as the root of the spanning tree network. It selects a root port
on each bridging device (except for the root device) which incurs the lowest path cost when
forwarding a packet from that device to the root device. Then it selects a designated
bridging device from each LAN which incurs the lowest path cost when forwarding a
packet from that LAN to the root device. All ports connected to designated bridging
devices are assigned as designated ports. After determining the lowest cost spanning tree, it
enables all root ports and designated ports, and disables all other ports. Network packets
are therefore only forwarded between root ports and designated ports, eliminating any
possible network loops.
Once a stable network topology has been established, all bridges listen for Hello BPDUs
(Bridge Protocol Data Units) transmitted from the Root Bridge. If a bridge does not get a
Hello BPDU after a predefined interval (Maximum Age), the bridge assumes that the link
to the Root Bridge is down. This bridge will then initiate negotiations with other bridges to
reconfigure the network to reestablish a valid network topology.

Parameters description:
Basic Settings
Protocol Version
The STP protocol version setting. Valid values are STP,
RSTP and MSTP.
Bridge Priority
Controls the bridge priority. Lower numeric values have
better priority. The bridge priority plus the MSTI instance
number, concatenated with the 6-byte MAC address of the
switch forms a Bridge Identifier. For MSTP operation, this
is the priority of the CIST. Otherwise, this is the priority of
the STP/RSTP bridge.
Forward Delay
The delay used by STP Bridges to transit Root and
Designated Ports to Forwarding (used in STP compatible
mode). Valid values are in the range 4 to 30 seconds.
Max Age
The maximum age of the information transmitted by the
Bridge when it is the Root Bridge. Valid values are in the
range 6 to 40 seconds, and MaxAge must be <=
(FwdDelay-1)*2.
Maximum Hop Count
This defines the initial value of remaining Hops for MSTI
information generated at the boundary of an MSTI region. It
defines how many bridges a root bridge can distribute its
BPDU information to. Valid values are in the range 6 to 40
hops.
Transmit Hold Count
The number of BPDU's a bridge port can send per second.
When exceeded, transmission of the next BPDU will be
delayed. Valid values are in the range 1 to 10 BPDU's per
second.

the error-disabled state, and will be removed from the
active topology.
Port Error Recovery
Control whether a port in the error-disabled state
automatically will be enabled after a certain time. If
recovery is not enabled, ports have to be disabled and
re-enabled for normal STP operation. The condition is also
cleared by a system reboot.

mapped. Due to the reason that you need to set the list of VLANs mapped to the MSTI, the
VLANs must be separated with comma and/or space. A VLAN can only be mapped to one
MSTI. An unused MSTI should just be left empty (i.e., not having any VLANs mapped to
it).

Parameters description:
70
Port
The switch port number of the logical STP port.
STP Enabled
Controls whether STP is enabled on this switch port.
Path Cost
Controls the path cost incurred by the port. The Auto setting
will set the path cost as appropriate by the physical link
speed, using the 802.1D recommended values. Using the
Specific setting, a user-defined value can be entered. The
path cost is used when establishing the active topology of
the network. Lower path cost ports are chosen as forwarding
ports in favour of higher path cost ports. Valid values are in
the range 1 to 200000000.
Priority
Controls the port priority. This can be used to control
priority of ports having identical port cost. (See above).
Admin Edge
Controls whether the operEdge flag should start as set or
VigorSwitch P2261 User’s Guide
cleared. (The initial operEdge state when a port is
initialized).
Auto Edge
Controls whether the bridge should enable automatic edge
detection on the bridge port. This allows operEdge to be
derived from whether BPDU's are received on the port or
not.
Restricted Role
If enabled, causes the port not to be selected as Root Port
for the CIST or any MSTI, even if it has the best spanning
tree priority vector. Such a port will be selected as an
Alternate Port after the Root Port has been selected. If set, it
can cause lack of spanning tree connectivity. It can be set by
a network administrator to prevent bridges external to a core
region of the network influence the spanning tree active
topology, possibly because those bridges are not under the
full control of the administrator. This feature is also known
as Root Guard.
Restricted TCN
If enabled, causes the port not to propagate received
topology change notifications and topology changes to other
ports. If set it can cause temporary loss of connectivity after
changes in a spanning tree's active topology as a result of
persistently incorrect learned station location information. It
is set by a network administrator to prevent bridges external
to a core region of the network, causing address flushing in
that region, possibly because those bridges are not under the
full control of the administrator or the physical link state of
the attached LANs transits frequently.
BPDU Guard
If enabled, causes the port to disable itself upon receiving
valid BPDU's. Contrary to the similar bridge setting, the
port Edge status does not affect this setting.
A port entering error-disabled state due to this setting is
subject to the bridge Port Error Recovery setting as well.
Point-to-point
Controls whether the port connects to a point-to-point LAN
rather than to a shared medium. This can be automatically
determined, or forced either true or false. Transition to the
forwarding state is faster for point-to-point LANs than for
shared media.

2.3.13 IGMP Snooping – General Setup
A switch supported IGMP Snooping with the functions of query, report and leave, a type of
packet exchanged between IP Multicast Router/Switch and IP Multicast Host, can update
the information of the Multicast table when a member (port) joins or leaves an IP Multicast
Destination Address. With this function, once a switch receives an IP multicast packet, it
will forward the packet to the members who joined in a specified IP multicast group before.
The packets will be discarded by the IGMP Snooping if the user transmits multicast
packets to the multicast group that had not been built up in advance. IGMP mode enables
the switch to issue IGMP function that you enable IGMP proxy or snooping on the switch,
which connects to a router closer to the root of the tree. This interface is the upstream
interface. The router on the upstream interface should be running IGMP.
IGMP Snooping is used to establish the multicast groups to forward the multicast packet to
the member ports, and, in nature, avoids wasting the bandwidth while IP multicast packets
are running over the network. This is because a switch that does not support IGMP or
IGMP Snooping can not tell the multicast packet from the broadcast packet, so it can only
treat them all as the broadcast packet. Without IGMP Snooping, the multicast packet
forwarding function is plain and nothing is different from broadcast packet.

2.3.15 IGMP Snooping – Port Group Filtering
With this feature, you can filter multicast joins on a per-port basis by configuring IP
multicast profiles and associating them with individual switch ports. An IGMP profile can
contain one or more multicast groups and specifies whether access to the group is permitted
or denied. If an IGMP profile denying access to a multicast group is applied to a switch
port, the IGMP join report requesting the stream of IP multicast traffic is dropped, and the
port is not allowed to receive IP multicast traffic from that group. If the filtering action
permits access to the multicast group, the IGMP report from the port is forwarded for
normal processing.
IGMP filtering controls only IGMP membership join reports and has no relationship to the
function that directs the forwarding of IP multicast traffic.
Function name:
IGMP Snooping – Port Group Filtering
Function description:
The function is used to set the IGMP Port Group Filtering. With the IGMP filtering feature,
a user can exert this type of control. In some network Application environments, as like the

2.3.18 IGMP Snooping- IPv4 SSM Information
Source Specific Multicast (SSM) is a datagram delivery model that best supports
one-to-many applications, also known as broadcast applications. SSM is a core network
technology of IP multicast targeted for audio and video broadcast application
environments.
For the SSM delivery mode, an IP multicast receiver host must use IGMP Version 3
(IGMPv3) to subscribe to channel (S, G). By subscribing to this channel, the receiver host
is indicating that it wants to receive IP multicast traffic sent by source host S to group G.
The network will deliver IP multicast packets from source host S to group G to all hosts in
the network that have subscribed to the channel (S, G).
SSM does not require group address allocation within the network, only within each source
host. Different applications running on the same source host must use different SSM
groups. Different applications running on different source hosts can arbitrarily reuse SSM
group addresses without causing any excess traffic on the network.
Addresses in the range 232.0.0.0/8 (232.0.0.0 to 232.255.255.255) are reserved for SSM by
IANA. In the switch, you can configure SSM for arbitrary IP multicast addresses also.

2.3.19 MLD Snooping – General Setup
Curiously enough, a network node that acts as a source of IPv6 multicast traffic is only an
indirect participant in MLD snooping—it just provides multicast traffic, and MLD doesn’t
interact with it. (Note, however, that in an application like desktop conferencing a network
node may act as both a source and an MLD host; but MLD interacts with that node only in
its role as an MLD host.)
A source node creates multicast traffic by sending packets to a multicast address. In IPv6,
addresses with the first eight bits set (that is, “FF” as the first two characters of the address)
are multicast addresses, and any node that listens to such an address will receive the traffic
sent to that address. Application software running on the source and destination systems
cooperates to determine what multicast address to use. (Note that this is a function of the
application software, not of MLD.)
When MLD snooping is enabled on a VLAN, the switch acts to minimize unnecessary
multicast traffic. If the switch receives multicast traffic destined for a given multicast

2.3.25 MVR – General Setup
The MVR feature enables multicast traffic forwarding on the Multicast VLAN. In a
multicast television application, a PC or a television with a set-top box can receive
the multicast stream. Multiple set-top boxes or PCs can be connected to one subscriber port,
which is a switch port configured as an MVR receiver port. When a subscriber selects a
channel, the set-top box or PC sends an IGMP join message to Switch A to join the
appropriate multicast. Uplink ports that send and receive multicast data to and from the
multicast VLAN are called MVR source ports.

2.3.28 LLDP – LLDP General Setup
The switch supports the LLDP. For current information on your switch model, The Link
Layer Discovery Protocol (LLDP) provides a standards-based method for enabling
switches to advertise themselves to adjacent devices and to learn about adjacent LLDP
devices. The Link Layer Discovery Protocol (LLDP) is a vendor-neutral Link Layer
protocol in the Internet Protocol Suite used by network devices for advertising their
identity, capabilities, and neighbors on a IEEE 802 local area network, principally wired
Ethernet. The protocol is formally referred to by the IEEE as Station and Media Access
Control Connectivity Discovery specified in standards document IEEE 802.1AB.
Function name:
LLDP – LLDP General Setup
Function description:
The function is used to inspect and configure the current LLDP port settings.
Parameters description:
Tx Interval
The switch periodically transmits LLDP frames to its
neighbours for having the network discovery information
up-to-date. The interval between each LLDP frame is
determined by the Tx Interval value. Valid values are
restricted to 5 - 32768 seconds.
Tx Hold
Each LLDP frame contains information about how long the
information in the LLDP frame shall be considered valid.
The LLDP information valid period is set to Tx Hold
multiplied by Tx Interval seconds. Valid values are
restricted to 2 - 10 times.
Tx Delay
If some configuration is changed (e.g. the IP address) a new
LLDP frame is transmitted, but the time between the LLDP
frames will always be at least the value of Tx Delay
seconds. Tx Delay cannot be larger than 1/4 of the Tx
Interval value. Valid values are restricted to 1 - 8192
seconds.
Tx Reinit
When a port is disabled, LLDP is disabled or the switch is
VigorSwitch P2261 User’s Guide
95
rebooted, an LLDP shutdown frame is transmitted to the
neighboring units, signaling that the LLDP information isn't
valid anymore. Tx Reinit controls the amount of seconds
between the shutdown frame and a new LLDP initialization.
Valid values are restricted to 1 - 10 seconds.
96
Port
The switch port number of the logical LLDP port.
Mode
Select LLDP mode.
Rx only The switch will not send out LLDP information,
but LLDP information from neighbour units is analyzed.
Tx only The switch will drop LLDP information received
from neighbours, but will send out LLDP information.
Disabled The switch will not send out LLDP information,
and will drop LLDP information received from neighbours.
Enabled The switch will send out LLDP information, and
will analyze LLDP information received from neighbours.
CDP Aware
Select CDP awareness.
The CDP operation is restricted to decoding incoming CDP
frames (The switch doesn't transmit CDP frames). CDP
frames are only decoded if LLDP on the port is enabled.
Only CDP TLVs that can be mapped to a corresponding
field in the LLDP neighbours' table are decoded. All other
TLVs are discarded (Unrecognized CDP TLVs and
discarded CDP frames are not shown in the LLDP
statistics.). CDP TLVs are mapped onto LLDP neighbours'
table as shown below.
CDP TLV "Device ID" is mapped to the LLDP "Chassis
ID" field.
CDP TLV "Address" is mapped to the LLDP "Management
Address" field. The CDP address TLV can contain multiple
addresses, but only the first address is shown in the LLDP
neighbours’ table.
CDP TLV "Port ID" is mapped to the LLDP "Port ID" field.
CDP TLV "Version and Platform" is mapped to the LLDP
"System Description" field.
Both the CDP and LLDP support "system capabilities", but
the CDP capabilities cover capabilities that are not part of
the LLDP. These capabilities are shown as "others" in the
LLDP neighbours' table.
If all ports have CDP awareness disabled the switch
forwards CDP frames received from neighbour devices. If at
least one port has CDP awareness enabled all CDP frames
are terminated by the switch.
Note: When CDP awareness on a port is disabled the CDP
information isn't removed immediately, but gets when the
hold time is exceeded.
Port Descr
Optional TLV: When checked the "port description" is
included in LLDP information transmitted.
Sys Name
Optional TLV: When checked the "system name" is
included in LLDP information transmitted.

2.3.30 LLDP – LLDP-MED General Setup
Media Endpoint Discovery is an enhancement of LLDP, known as LLDP-MED, that
provides the following facilities:
Auto-discovery of LAN policies (such as VLAN, Layer 2 Priority and Differentiated
services (Diffserv) settings) enabling plug and play networking.
Device location discovery to allow creation of location databases and, in the case of Voice
over Internet Protocol (VoIP), Enhanced 911 services.
Extended and automated power management of Power over Ethernet (PoE) end points.
Inventory management, allowing network administrators to track their network devices,

Rapid startup and Emergency Call Service Location
Identification Discovery of endpoints is a critically
important aspect of VoIP systems in general. In addition, it
is best to advertise only those pieces of information which
are specifically relevant to particular endpoint types (for
example only advertise the voice network policy to
permitted voice-capable devices), both in order to conserve
the limited LLDPU space and to reduce security and system
integrity issues that can come with inappropriate knowledge
of the network policy.
With this in mind LLDP-MED defines an LLDP-MED Fast
Start interaction between the protocol and the application
layers on top of the protocol, in order to achieve these
related properties. Initially, a Network Connectivity Device
will only transmit LLDP TLVs in an LLDPDU. Only after
an LLDP-MED Endpoint Device is detected, will an
LLDP-MED capable Network Connectivity Device start to
advertise LLDP-MED TLVs in outgoing LLDPDUs on the
associated port. The LLDP-MED application will
temporarily speed up the transmission of the LLDPDU to
start within a second, when a new LLDP-MED neighbour
has been detected in order share LLDP-MED information as
fast as possible to new neighbours.
Because there is a risk of an LLDP frame being lost during
transmission between neighbours, it is recommended to
repeat the fast start transmission multiple times to increase
the possibility of the neighbours receiving the LLDP frame.
With Fast start repeat count it is possible to specify the
number of times the fast start transmission would be
repeated. The recommended value is 4 times, given that 4
LLDP frames with a 1 second interval will be transmitted,
when an LLDP frame with new information is received.
99
It should be noted that LLDP-MED and the LLDP-MED
Fast Start mechanism is only intended to run on links
between LLDP-MED Network Connectivity Devices and
Endpoint Devices, and as such does not apply to links
between LAN infrastructure elements, including Network
Connectivity Devices, or other types of links.
Coordinates Location
Latitude
Latitude SHOULD be normalized to within 0-90 degrees
with a maximum of 4 digits.
It is possible to specify the direction to either North of the

Policies
Network Policy Discovery enables the efficient discovery
and diagnosis of mismatch issues with the VLAN
configuration, along with the associated Layer 2 and Layer
3 attributes, which apply for a set of specific protocol
applications on that port. Improper network policy
configurations are a very significant issue in VoIP
VigorSwitch P2261 User’s Guide
101
environments that frequently result in voice quality
degradation or loss of service.
Policies are only intended for use with applications that
have specific 'real-time' network policy requirements, such
as interactive voice and/or video services.
The network policy attributes advertised are:
1. Layer 2 VLAN ID (IEEE 802.1Q-2003)
2. Layer 2 priority value (IEEE 802.1D-2004)
3. Layer 3 Diffserv code point (DSCP) value (IETF RFC
2474)
This network policy is potentially advertised and associated
with multiple sets of application types supported on a given
port. The application types specifically addressed are:
1. Voice
2. Guest Voice
3. Softphone Voice
4. Video Conferencing
5. Streaming Video
6. Control / Signalling (conditionally support a separate
network policy for the media types above)
A large network may support multiple VoIP policies across
the entire organization, and different policies per application
type. LLDP-MED allows multiple policies to be advertised
per port, each corresponding to a different application type.
Different ports on the same Network Connectivity Device
may advertise different sets of policies, based on the
authenticated user identity or port configuration.
It should be noted that LLDP-MED is not intended to run
on links other than between Network Connectivity Devices
and Endpoints, and therefore does not need to advertise the
multitude of network policies that frequently run on an
aggregated link interior to the LAN.

Application Type
Intended use of the application types:
1. Voice - for use by dedicated IP Telephony handsets and
other similar appliances supporting interactive voice
services. These devices are typically deployed on a separate
VLAN for ease of deployment and enhanced security by
isolation from data applications.
2. Voice Signaling (conditional) - for use in network
topologies that require a different policy for the voice
signaling than for the voice media. This application type
should not be advertised if all the same network policies
apply as those advertised in the Voice application policy.
VigorSwitch P2261 User’s Guide
3. Guest Voice - support a separate 'limited feature-set' voice
service for guest users and visitors with their own IP
Telephony handsets and other similar appliances supporting
interactive voice services.
4. Guest Voice Signaling (conditional) - for use in network
topologies that require a different policy for the guest voice
signaling than for the guest voice media. This application
type should not be advertised if all the same network
policies apply as those advertised in the Guest Voice
application policy.
5. Softphone Voice - for use by softphone applications on
typical data centric devices, such as PCs or laptops. This
class of endpoints frequently does not support multiple
VLANs, if at all, and are typically configured to use an
'untagged' VLAN or a single 'tagged' data specific VLAN.
When a network policy is defined for use with an 'untagged'
VLAN (see Tagged flag below), then the L2 priority field is
ignored and only the DSCP value has relevance.
6. Video Conferencing - for use by dedicated Video
Conferencing equipment and other similar appliances
supporting real-time interactive video/audio services.
7. Streaming Video - for use by broadcast or multicast based
video content distribution and other similar applications
supporting streaming video services that require specific
network policy treatment. Video applications relying on
TCP with buffering would not be an intended use of this
application type.
8. Video Signaling (conditional) - for use in network
topologies that require a separate policy for the video
signaling than for the video media. This application type
should not be advertised if all the same network policies
apply as those advertised in the Video Conferencing
application policy.
Tag
Tag indicating whether the specified application type is
using a 'tagged' or an 'untagged' VLAN.
Untagged indicates that the device is using an untagged
frame format and as such does not include a tag header as
defined by IEEE 802.1Q-2003. In this case, both the VLAN
ID and the Layer 2 priority fields are ignored and only the
DSCP value has relevance.
Tagged indicates that the device is using the IEEE 802.1Q
tagged frame format, and that both the VLAN ID and the
Layer 2 priority values are being used, as well as the DSCP
value. The tagged format includes an additional field,
known as the tag header. The tagged frame format also
includes priority tagged frames as defined by IEEE
802.1Q-2003.
VLAN ID
VLAN identifier (VID) for the port as defined in IEEE
802.1Q-2003.
L2 Priority
L2 Priority is the Layer 2 priority to be used for the
specified application type. L2 Priority may specify one of
VigorSwitch P2261 User’s Guide
103
eight priority levels (0 through 7), as defined by IEEE
802.1D-2004. A value of 0 represents use of the default
priority as defined in IEEE 802.1D-2004.
DSCP
DSCP value to be used to provide Diffserv node behaviour
for the specified application type as defined in IETF RFC
2474. DSCP may contain one of 64 code point values (0
through 63). A value of 0 represents use of the default
DSCP value as defined in RFC 2475.

Device Definition
VigorSwitch P2261 User’s Guide
LLDP-MED Endpoint Devices, as defined in TIA-1057, are
located at the IEEE 802 LAN network edge, and participate
in IP communication service using the LLDP-MED
105
framework.
Within the LLDP-MED Endpoint Device category, the
LLDP-MED scheme is broken into further Endpoint Device
Classes, as defined in the following.
Each LLDP-MED Endpoint Device Class is defined to build
upon the capabilities defined for the previous Endpoint
Device Class. For-example will any LLDP-MED Endpoint
Device claiming compliance as a Media Endpoint (Class II)
also support all aspects of TIA-1057 applicable to Generic
Endpoints (Class I), and any LLDP-MED Endpoint Device
claiming compliance as a Communication Device (Class III)
will also support all aspects of TIA-1057 applicable to both
Media Endpoints (Class II) and Generic Endpoints (Class I).
LLDP-MED Generic
Endpoint (Class I)
The LLDP-MED Generic Endpoint (Class I) definition is
applicable to all endpoint products that require the base
LLDP discovery services defined in TIA-1057, however do
not support IP media or act as an end-user communication
appliance. Such devices may include (but are not limited to)
IP Communication Controllers, other communication
related servers, or any device requiring basic services as
defined in TIA-1057.
Discovery services defined in this class include LAN
configuration, device location, network policy, power
management, and inventory management.
LLDP-MED Media
Endpoint (Class II)
The LLDP-MED Media Endpoint (Class II) definition is
applicable to all endpoint products that have IP media
capabilities however may or may not be associated with a
particular end user. Capabilities include all of the
capabilities defined for the previous Generic Endpoint Class
(Class I), and are extended to include aspects related to
media streaming. Example product categories expected to
adhere to this class include (but are not limited to) Voice /
Media Gateways, Conference Bridges, Media Servers, and
similar.
Discovery services defined in this class include
media-type-specific network layer policy discovery.
LLDP-MED
Communication Endpoint
(Class III)
The LLDP-MED Communication Endpoint (Class III)
definition is applicable to all endpoint products that act as
end user communication appliances supporting IP media.
Capabilities include all of the capabilities defined for the
previous Generic Endpoint (Class I) and Media Endpoint
(Class II) classes, and are extended to include aspects
related to end user devices. Example product categories
expected to adhere to this class include (but are not limited
to) end user communication appliances, such as IP Phones,
PC-based softphones, or other communication appliances
that directly support the end user.
Discovery services defined in this class include provision of
location identifier (including ECS / E911 information),
embedded L2 switch support, inventory management.

Policy
Policy indicates that an Endpoint Device wants to explicitly
advertise that the policy is required by the device. Can be
either Defined or Unknown
Unknown: The network policy for the specified application
VigorSwitch P2261 User’s Guide
107
type is currently unknown.
Defined: The network policy is defined.
TAG
TAG is indicative of whether the specified application type
is using a tagged or an untagged VLAN. Can be Tagged or
Untagged.
Untagged: The device is using an untagged frame format
and as such does not include a tag header as defined by
IEEE 802.1Q-2003.
Tagged: The device is using the IEEE 802.1Q tagged frame
format.
108
VLAN ID
VLAN ID is the VLAN identifier (VID) for the port as
defined in IEEE 802.1Q-2003. A value of 1 through 4094 is
used to define a valid VLAN ID. A value of 0 (Priority
Tagged) is used if the device is using priority tagged frames
as defined by IEEE 802.1Q-2003, meaning that only the
IEEE 802.1D priority level is significant and the default

2.3.32 LLDP – EEE
By using EEE power savings can be achieved at the expense of traffic latency. This latency
occurs due to that the circuits EEE turn off to save power, need time to boot up before
sending traffic over the link. This time is called "wakeup time". To achieve minimal
latency, devices can use LLDP to exchange information about their respective tx and rx
"wakeup time ", as a way to agree upon the minimum wakeup time they need.
Function name:
Aggregation – Static Trunk
Function description:
The function is used to provide an overview of EEE information exchanged by LLDP.
Parameters description:
Local Port
The port on which LLDP frames are received or
transmitted.
Tx Tw
The link partner's maximum time that transmit path can
hold-off sending data after deassertion of LPI.
Rx Tw
The link partner's time that receiver would like the
transmitter to hold-off to allow time for the receiver to wake
from sleep.
Fallback Receive Tw
The link partner's fallback receive Tw.
A receiving link partner may inform the transmitter of an
alternate desired Tw_sys_tx. Since a receiving link partner
is likely to have discrete levels for savings, this provides the
transmitter with additional information that it may use for a
more efficient allocation. Systems that do not implement
this option default the value to be the same as that of the
Receive Tw_sys_tx.
Echo Tx Tw
The link partner's Echo Tx Tw value.
The respective echo values shall be defined as the local link
partner reflection (echo) of the remote link partners
respective values. When a local link partner receives its
VigorSwitch P2261 User’s Guide
109
echoed values from the remote link partner it can determine
whether or not the remote link partner has received,
registered and processed its most recent values. For
example, if the local link partner receives echoed
parameters that do not match the values in its local MIB,
then the local link partner infers that the remote link
partners request was based on stale information.
110
Echo Rx Tw
The link partner's Echo Rx Tw value.
Resolved Tx Tw
The resolved Tx Tw for this link. Note : NOT the link
partner
The resolved value that is the actual "tx wakeup time "used
for this link (based on EEE information exchanged via
LLDP).
Resolved Rx Tw
The resolved Rx Tw for this link. Note : NOT the link
partner
The resolved value that is the actual "tx wakeup time" used
for this link (based on EEE information exchanged via
LLDP).

If an LLDP frame is received on a port, and the switch's
VigorSwitch P2261 User’s Guide
111
internal table has run full, the LLDP frame is counted and
discarded. This situation is known as "Too Many
Neighbours" in the LLDP standard. LLDP frames require a
new entry in the table when the Chassis ID or Remote Port
ID is not already contained within the table. Entries are
removed from the table when a given port's link is down, an
LLDP shutdown frame is received, or when the entry ages
out.
TLVs Discarded
Each LLDP frame can contain multiple pieces of
information, known as TLVs (TLV is short for "Type
Length Value"). If a TLV is malformed, it is counted and
discarded.

2.3.39 Filtering Data Base – General Setup
Filtering Data Base gathers many functions, including MAC Table Information, Static
MAC Learning, which cannot be categorized to some function type.
Switching of frames is based upon the DMAC address contained in the frame. The switch
builds up a table that maps MAC addresses to switch ports for knowing which ports the
frames should go to (based upon the DMAC address in the frame). This table contains both
116
VigorSwitch P2261 User’s Guide
static and dynamic entries. The static entries are configured by the network administrator if
the administrator wants to do a fixed mapping between the DMAC address and switch
ports.
The frames also contain a MAC address (SMAC address), which shows the MAC address
of the equipment sending the frame. The SMAC address is used by the switch to
automatically update the MAC table with these dynamic MAC addresses. Dynamic entries
are removed from the MAC table if no frame with the corresponding SMAC address has
been seen after a configurable age time.
Function name:

2.3.46 VLAN – Private VLANs – Port Isolation
Port Isolation provides for an apparatus and method to isolate ports on layer 2 switches on
the same VLAN to restrict traffic flow. The apparatus comprises a switch having said
plurality of ports, each port configured as a protected port or a non-protected port. An
address table memory stores an address table having a destination address and port number
pair. A forwarding map generator generates a forwarding map which is responsive to a
destination address of a data packet. The method for isolating ports on a layer 2 switch
comprises configuring each of the ports on the layer 2 switch as a protected port or a
non-protected port. A destination address on an data packet is matched with a physical
address on said layer 2 switch and a forwarding map is generated for the data packet based
upon the destination address on the data packet. The data packet is then sent to the plurality
of ports pursuant to the forwarding map generated based upon whether the ingress port was
configured as a protected or non-protected port.

2.3.47 VLAN – MAC-based VLAN – General Setup
MAC address-based VLAN decides the VLAN for forwarding an untagged frame based on
the source MAC address of the frame.
A most common way of grouping VLAN members is by port, hence the name port-based
VLAN. Typically, the device adds the same VLAN tag to untagged packets that are
received through the same port. Later on, these packets can be forwarded in the same
VLAN. Port-based VLAN is easy to configure, and applies to networks where the locations
of terminal devices are relatively fixed. As mobile office and wireless network access gain
more popularity, the ports that terminal devices use to access the networks are very often
non-fixed. A device may access a network through Port A this time, but through Port B the
next time. If Port A and Port B belong to different VLANs, the device will be assigned to a
different VLAN the next time it accesses the network. As a result, it will not be able to use
the resources in the old VLAN. On the other hand, if Port A and Port B belong to the same
VLAN, after terminal devices access the network through Port B, they will have access to
the same resources as those accessing the network through Port A do, which brings security
issues. To provide user access and ensure data security in the mean time, the MAC-based
VLAN technology is developed.
MAC-based VLANs group VLAN members by MAC address. With MAC-based VLAN
configured, the device adds a VLAN tag to an untagged frame according to its source MAC
address. MAC-based VLANs are mostly used in conjunction with security technologies
such as 802.1X to provide secure, flexible network access for terminal devices

2.3.49 VLAN – Protocol-based VLAN – Protocol Group
This section describe Protocol -based VLAN, The Switch support Protocol include
Ethernet LLC SNAP Protocol, and LLC.
The Logical Link Control (LLC) data communication protocol layer is the upper sub-layer
of the Data Link Layer (which is itself layer 2, just above the Physical Layer) in the
seven-layer OSI reference model. It provides multiplexing mechanisms that make it
possible for several network protocols (IP, IPX, Decnet and Appletalk) to coexist within a
multipoint network and to be transported over the same network media, and can also
provide flow control and automatic repeat request (ARQ) error management mechanisms.
SNAP
The Subnetwork Access Protocol (SNAP) is a mechanism for multiplexing, on networks
using IEEE 802.2 LLC, more protocols than can be distinguished by the 8-bit
802.2 Service Access Point (SAP) fields. SNAP supports identifying protocols
by Ethernet type field values; it also supports vendor-private protocol identifier spaces. It is
used with IEEE 802.3, IEEE 802.4, IEEE 802.5, IEEE 802.11 and other IEEE 802 physical
network layers, as well as with non-IEEE 802 physical network layers such as FDDI that
use 802.2 LLC.
Function name:
VLAN – Protocol-based VLAN – Protocol Group
Function description:
The function is used to add new protocols to Group Name (unique for each Group)
mapping entries as well as used to allow you to see and delete the already mapped entries.
Parameters description:
132
Delete
Check this box to delete the entry.
Frame Type
Frame Type can have one of the following values:
z Ethernet
z LLC
z SNAP
Note: On changing the Frame type field, valid value of the
VigorSwitch P2261 User’s Guide
following text field will vary depending on the new frame
type you selected.
Value
Valid value that can be entered in this text field depends on
the option selected from the preceding Frame Type
selection menu.
Below is the criteria for three different Frame Types:
z For Ethernet: Values in the text field when Ethernet is
selected as a Frame Type is called etype. Valid values
for etype ranges from 0x0600-0xffff
z For LLC: Valid value in this case is comprised of two
different sub-values.
a. DSAP: 1-byte long string (0x00-0xff)
b. SSAP: 1-byte long string (0x00-0xff)
z For SNAP: Valid value in this case also is comprised
of two different sub-values.
a. OUI: OUI (Organizationally Unique Identifier) is
value in format of xx-xx-xx where each pair (xx)
in string is a hexadecimal value ranges from
0x00-0xff.
b. PID: If the OUI is hexadecimal 000000, the
protocol ID is the Ethernet type (EtherType) field
value for the protocol running on top of SNAP; if
the OUI is an OUI for a particular organization,
the protocol ID is a value assigned by that
organization to the protocol running on top of
SNAP.
In other words, if value of OUI field is 00-00-00
then value of PID will be etype (0x0600-0xffff)
and if value of OUI is other than 00-00-00 then
valid value of PID will be any value from 0x0000
to 0xffff.

2.3.53 GARP – General Setup
The Generic Attribute Registration Protocol (GARP) provides a generic framework
whereby devices in a bridged LAN, e.g. end stations and switches, can register and
de-register attribute values, such as VLAN Identifiers, with each other. In doing so, the
attributes are propagated to devices in the bridged LAN, and these devices form a
reachability tree that is a subset of an active topology. GARP defines the architecture, rules
VigorSwitch P2261 User’s Guide
137
of operation, state machines and variables for the registration and de-registration of
attribute values.
A GARP participation in a switch or an end station consists of a GARP application
component, and a GARP Information Declaration (GID) component associated with each
port or the switch. The propagation of information between GARP participants for the
same application in a bridge is carried out by the GARP Information Propagation (GIP)
component. Protocol exchanges take place between GARP participants by means of LLC
Type 1 services, using the group MAC address and PDU format defined for the GARP
application concerned.

2.3.56 QoS – Port Classification
The switch supports four QoS queues per port with strict or weighted fair queuing
scheduling. It supports QoS Control Lists (QCL) for advance programmable QoS
classification, based on IEEE 802.1p, Ethertype, VID, IPv4/IPv6 DSCP and UDP/TCP
ports and ranges.
High flexibility is in the classification of incoming frames to a QoS class. The QoS
classification looks for information up to Layer 4, including IPv4 and IPv6 DSCP, IPv4
TCP/UDP port numbers, and user priority of tagged frames. This QoS classification
mechanism is implemented in a QoS control list (QCL). The QoS class assigned to a frame
is used throughout the device for providing queuing, scheduling, and congestion control
guarantees to the frame according to what was configured for that specific QoS class.
The switch support advanced memory control mechanisms providing excellent
performance of all QoS classes under any traffic scenario, including jumbo frame. A super
priority queue with dedicated memory and strict highest priority will be in the arbitration.
The ingress super priority queue allows traffic recognized as CPU traffic to be received and
queued for transmission to the CPU even when all the QoS class queues are congested.

TTL
The TTL value is used by UPnP to send SSDP
advertisement messages. Valid values are in the range 1 to
255.
Advertising Duration
The duration, carried in SSDP packets, is used to inform a
control point or control points how often it or they should
receive an SSDP advertisement message from this switch. If
a control point does not receive any message within the
duration, it will think that the switch no longer exists. Due
to the unreliable nature of UDP, in the standard it is
recommended that such refreshing of advertisements to be
done at less than one-half of the advertising duration. In the
implementation, the switch sends SSDP messages
periodically at the interval one-half of the advertising
duration minus 30 seconds. Valid values are in the range

2.4.15 NAS – General Setup
Function name:
NAS – General Setup
Function description:
The function is used to configure the NAS parameters of the switch. The NAS server can
be employed to connect users to a variety of resources including Internet access,
conference calls, printing documents on shared printers, or by simply logging on to the
Internet.
It can configure NAS setting of IEEE 802.1X, MAC-based authentication system, and port
settings. The NAS configuration consists of two sections, a system- and a port-wide.
Parameters description:
System Configuration
Mode
Indicates if NAS is globally enabled or disabled on the
switchstack. If it is disabled, all ports are allowed
forwarding of frames.
Reauthentication Enabled
If checked, successfully authenticated supplicants/clients
are reauthenticated after the interval specified by the
VigorSwitch P2261 User’s Guide
183
Reauthentication Period. Reauthentication for
802.1X-enabled ports can be used to detect if a new device
is plugged into a switch port or if a supplicant is no longer
attached.
For MAC-based ports, reauthentication is only useful if the
RADIUS server configuration has changed. It does not
involve communication between the switch and the client,
and therefore doesn't imply that a client is still present on a
port (see Aging Period below).
184
Reauthentication Period
Determines the period, in seconds, after which a connected
client must be reauthenticated. This is only active if the
Reauthentication Enabled checkbox is checked. Valid
values are in the range 1 to 3600 seconds.
EAPOL Timeout
Determines the time for retransmission of Request Identity
EAPOL frames.
Valid values are in the range 1 to 255 seconds. This has no
effect for MAC-based ports.
Aging Period
This setting applies to the following modes, i.e. modes
using the Port Security functionality to secure MAC
addresses:
• Single 802.1X
• Multi 802.1X
• MAC-Based Auth.
When the NAS module uses the Port Security module to
secure MAC addresses, the Port Security module needs to
check for activity on the MAC address in question at regular
intervals and free resources if no activity is seen within a
given period of time. This parameter controls exactly this
period and can be set to a number between 10 and 1000000
seconds.
If reauthentication is enabled and the port is in an
802.1X-based mode, this is not so critical, since supplicants
that are no longer attached to the port will get removed upon
the next reauthentication, which will fail. But if
reauthentication is not enabled, the only way to free
resources is by aging the entries.
For ports in MAC-based Auth. mode, reauthentication
doesn't cause direct communication between the switch and
the client, so this will not detect whether the client is still
attached or not, and the only way to free any resources is to
age the entry.
Hold Time
This setting applies to the following modes, i.e. modes
using the Port Security functionality to secure MAC
addresses:
• Single 802.1X
• Multi 802.1X
• MAC-Based Auth.
If a client is denied access - either because the RADIUS
server denies the client access or because the RADIUS
server request times out (according to the timeout specified
VigorSwitch P2261 User’s Guide
on the "Configuration →Security →AAA" page) - the client
is put on hold in the Unauthorized state. The hold timer
does not count during an on-going authentication.
In MAC-based Auth mode, the switch will ignore new
frames coming from the client during the hold time.
The Hold Time can be set to a number between 10 and
1000000 seconds.
RADIUS-Assigned QoS
Enabled
RADIUS-assigned QoS provides a means to centrally
control the traffic class to which traffic coming from a
successfully authenticated supplicant is assigned on the
switch. The RADIUS server must be configured to transmit
special RADIUS attributes to take advantage of this feature
(see RADIUS-Assigned QoS Enabled below for a detailed
description).
The "RADIUS-Assigned QoS Enabled" checkbox provides
a quick way to globally enable/disable RADIUS-server
assigned QoS Class functionality. When checked, the
individual ports' ditto setting determines whether
RADIUS-assigned QoS Class is enabled on that port. When
unchecked, RADIUS-server assigned QoS Class is disabled
on all ports.
RADIUS-Assigned
VLAN Enabled
RADIUS-assigned VLAN provides a means to centrally
control the VLAN on which a successfully authenticated
supplicant is placed on the switch. Incoming traffic will be
classified to and switched on the RADIUS-assigned VLAN.
The RADIUS server must be configured to transmit special
RADIUS attributes to take advantage of this feature (see
RADIUS-Assigned VLAN Enabled below for a detailed
description).
The "RADIUS-Assigned VLAN Enabled" checkbox
provides a quick way to globally enable/disable
RADIUS-server assigned VLAN functionality. When
checked, the individual ports' ditto setting determines
whether RADIUS-assigned VLAN is enabled on that port.
When unchecked, RADIUS-server assigned VLAN is
disabled on all ports.
Guest VLAN Enabled
A Guest VLAN is a special VLAN - typically with limited
network access - on which 802.1X-unaware clients are
placed after a network administrator-defined timeout. The
switch follows a set of rules for entering and leaving the
Guest VLAN as listed below.
The "Guest VLAN Enabled" checkbox provides a quick
way to globally enable/disable Guest VLAN functionality.
When checked, the individual ports' ditto setting determines
whether the port can be moved into Guest VLAN. When
unchecked, the ability to move to the Guest VLAN is
disabled on all ports.
Guest VLAN ID
This is the value that a port's Port VLAN ID is set to if a
port is moved into the Guest VLAN. It is only changeable if
the Guest VLAN option is globally enabled.
Valid values are in the range [1; 4095].
VigorSwitch P2261 User’s Guide
185
Max. Reauth. Count
The number of times the switch transmits an EAPOL
Request Identity frame without response before considering
entering the Guest VLAN is adjusted with this setting. The
value can only be changed if the Guest VLAN option is
globally enabled.
Valid values are in the range [1; 255].
Allow Guest VLAN if
EAPOL Seen
The switch remembers if an EAPOL frame has been
received on the port for the life-time of the port. Once the
switch considers whether to enter the Guest VLAN, it will
first check if this option is enabled or disabled. If disabled
(unchecked; default), the switch will only enter the Guest
VLAN if an EAPOL frame has not been received on the
port for the life-time of the port. If enabled (checked), the
switch will consider entering the Guest VLAN even if an
EAPOL frame has been received on the port for the
life-time of the port.
The value can only be changed if the Guest VLAN option is
globally enabled.
Port Configuration
186
Port
The port number for which the configuration below applies.
Admin State
If NAS is globally enabled, this selection controls the port's
authentication mode. The following modes are available:
Force Authorized - In this mode, the switch will send one
EAPOL Success frame when the port link comes up, and
any client on the port will be allowed network access
without authentication.
Force Unauthorized - In this mode, the switch will send one
EAPOL Failure frame when the port link comes up, and any
client on the port will be disallowed network access.
Port-based 802.1X - In the 802.1X-world, the user is called
the supplicant, the switch is the authenticator, and the
RADIUS server is the authentication server. The
authenticator acts as the man-in-the-middle, forwarding
requests and responses between the supplicant and the
authentication server. Frames sent between the supplicant
and the switch are special 802.1X frames, known as EAPOL
(EAP Over LANs) frames. EAPOL frames encapsulate EAP
PDUs (RFC3748). Frames sent between the switch and the
RADIUS server are RADIUS packets. RADIUS packets
also encapsulate EAP PDUs together with other attributes
like the switch's IP address, name, and the supplicant's port
number on the switch. EAP is very flexible, in that it allows
for different authentication methods, like MD5-Challenge,
PEAP, and TLS. The important thing is that the
authenticator (the switch) doesn't need to know which
authentication method the supplicant and the authentication
server are using, or how many information exchange frames
are needed for a particular method. The switch simply
encapsulates the EAP part of the frame into the relevant
type (EAPOL or RADIUS) and forwards it.
When authentication is complete, the RADIUS server sends
VigorSwitch P2261 User’s Guide
a special packet containing a success or failure indication.
Besides forwarding this decision to the supplicant, the
switch uses it to open up or block traffic on the switch port
connected to the supplicant.
Note: Suppose two backend servers are enabled and that the
server timeout is configured to X seconds (using the AAA
configuration page), and suppose that the first server in the
list is currently down (but not considered dead). Now, if the
supplicant retransmits EAPOL Start frames at a rate faster
than X seconds, then it will never get authenticated, because
the switch will cancel on-going backend authentication
server requests whenever it receives a new EAPOL Start
frame from the supplicant. And since the server hasn't yet
failed (because the X seconds haven't expired), the same
server will be contacted upon the next backend
authentication server request from the switch. This scenario
will loop forever. Therefore, the server timeout should be
smaller than the supplicant's EAPOL Start frame
retransmission rate.
Single 802.1X - In port-based 802.1X authentication, once a
supplicant is successfully authenticated on a port, the whole
port is opened for network traffic. This allows other clients
connected to the port (for instance through a hub) to
piggy-back on the successfully authenticated client and get
network access even though they really aren't authenticated.
To overcome this security breach, use the Single 802.1X
variant. Single 802.1X is really not an IEEE standard, but
features many of the same characteristics as does port-based
802.1X. In Single 802.1X, at most one supplicant can get
authenticated on the port at a time. Normal EAPOL frames
are used in the communication between the supplicant and
the switch. If more than one supplicant is connected to a
port, the one that comes first when the port's link comes up
will be the first one considered. If that supplicant doesn't
provide valid credentials within a certain amount of time,
another supplicant will get a chance. Once a supplicant is
successfully authenticated, only that supplicant will be
allowed access. This is the most secure of all the supported
modes. In this mode, the Port Security module is used to
secure a supplicant's MAC address once successfully
authenticated.
Multi 802.1X - In port-based 802.1X authentication, once a
supplicant is successfully authenticated on a port, the whole
port is opened for network traffic. This allows other clients
connected to the port (for instance through a hub) to
piggy-back on the successfully authenticated client and get
network access even though they really aren't authenticated.
To overcome this security breach, use the Multi 802.1X
variant.
Multi 802.1X is really not an IEEE standard, but features
many of the same characteristics as does port-based 802.1X.
Multi 802.1X is - like Single 802.1X - not an IEEE
standard, but a variant that features many of the same
VigorSwitch P2261 User’s Guide
187
characteristics. In Multi 802.1X, one or more supplicants
can get authenticated on the same port at the same time.
Each supplicant is authenticated individually and secured in
the MAC table using the Port Security module.
In Multi 802.1X it is not possible to use the multicast BPDU
MAC address as destination MAC address for EAPOL
frames sent from the switch towards the supplicant, since
that would cause all supplicants attached to the port to reply
to requests sent from the switch. Instead, the switch uses the
supplicant's MAC address, which is obtained from the first
EAPOL Start or EAPOL Response Identity frame sent by
the supplicant. An exception to this is when no supplicants
are attached. In this case, the switch sends EAPOL Request
Identity frames using the BPDU multicast MAC address as
destination - to wake up any supplicants that might be on
the port.
The maximum number of supplicants that can be attached to
a port can be limited using the Port Security Limit Control
functionality.
MAC-based Auth. - Unlike port-based 802.1X, MAC-based
authentication is not a standard, but merely a best-practices
method adopted by the industry. In MAC-based
authentication, users are called clients, and the switch acts
as the supplicant on behalf of clients. The initial frame (any
kind of frame) sent by a client is snooped by the switch,
which in turn uses the client's MAC address as both
username and password in the subsequent EAP exchange
with the RADIUS server. The 6-byte MAC address is
converted to a string on the following form
"xx-xx-xx-xx-xx-xx", that is, a dash (-) is used as separator
between the lower-cased hexadecimal digits. The switch
only supports the MD5-Challenge authentication method, so
the RADIUS server must be configured accordingly.
When authentication is complete, the RADIUS server sends
a success or failure indication, which in turn causes the
switch to open up or block traffic for that particular client,
using the Port Security module. Only then will frames from
the client be forwarded on the switch. There are no EAPOL
frames involved in this authentication, and therefore,
MAC-based Authentication has nothing to do with the
802.1X standard.
The advantage of MAC-based authentication over
port-based 802.1X is that several clients can be connected to
the same port (e.g. through a 3rd party switch or a hub) and
still require individual authentication, and that the clients
don't need special supplicant software to authenticate. The
advantage of MAC-based authentication over 802.1X-based
authentication is that the clients don't need special
supplicant software to authenticate. The disadvantage is that
MAC addresses can be spoofed by malicious users equipment whose MAC address is a valid RADIUS user can
be used by anyone. Also, only the MD5-Challenge method
is supported. The maximum number of clients that can be
188
VigorSwitch P2261 User’s Guide
attached to a port can be limited using the Port Security
Limit Control functionality.
RADIUS-Assigned QoS
Enabled
When RADIUS-Assigned QoS is both globally enabled and
enabled (checked) on a given port, the switch reacts to QoS
Class information carried in the RADIUS Access-Accept
packet transmitted by the RADIUS server when a supplicant
is successfully authenticated. If present and valid, traffic
received on the supplicant's port will be classified to the
given QoS Class. If (re-)authentication fails or the RADIUS
Access-Accept packet no longer carries a QoS Class or it's
invalid, or the supplicant is otherwise no longer present on
the port, the port's QoS Class is immediately reverted to the
original QoS Class (which may be changed by the
administrator in the meanwhile without affecting the
RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
• Single 802.1X
RADIUS attributes used in identifying a QoS Class:
Refer to the written documentation for a description of the
RADIUS attributes needed in order to successfully identify
a QoS Class. The User-Priority-Table attribute defined in
RFC4675 forms the basis for identifying the QoS Class in
an Access-Accept packet.
Only the first occurrence of the attribute in the packet will
be considered, and to be valid, it must follow this rule:
• All 8 octets in the attribute's value must be identical and
consist of ASCII characters in the range '0' - '3', which
translates into the desired QoS Class in the range [0; 3].
RADIUS-Assigned
VLAN Enabled
When RADIUS-Assigned VLAN is both globally enabled
and enabled (checked) for a given port, the switch reacts to
VLAN ID information carried in the RADIUS
Access-Accept packet transmitted by the RADIUS server
when a supplicant is successfully authenticated. If present
and valid, the port's Port VLAN ID will be changed to this
VLAN ID, the port will be set to be a member of that
VLAN ID, and the port will be forced into VLAN unaware
mode. Once assigned, all traffic arriving on the port will be
classified and switched on the RADIUS-assigned VLAN
ID.
If (re-)authentication fails or the RADIUS Access-Accept
packet no longer carries a VLAN ID or it's invalid, or the
supplicant is otherwise no longer present on the port, the
port's VLAN ID is immediately reverted to the original
VLAN ID (which may be changed by the administrator in
the meanwhile without affecting the RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
• Single 802.1X
For trouble-shooting VLAN assignments, use the "Monitor
→ VLANs→ VLAN Membership and VLAN Port" pages.
VigorSwitch P2261 User’s Guide
189
These pages show which modules have (temporarily)
overridden the current Port VLAN configuration.
RADIUS attributes used in identifying a VLAN ID:
RFC2868 and RFC3580 form the basis for the attributes
used in identifying a VLAN ID in an Access-Accept packet.
The following criteria are used:
• The Tunnel-Medium-Type, Tunnel-Type, and
Tunnel-Private-Group-ID attributes must all be present at
least once in the Access-Accept packet.
• The switch looks for the first set of these attributes that
have the same Tag value and fulfill the following
requirements (if Tag == 0 is used, the
Tunnel-Private-Group-ID does not need to include a Tag):
- Value of Tunnel-Medium-Type must be set to "IEEE-802"
(ordinal 6).
- Value of Tunnel-Type must be set to "VLAN" (ordinal
13).
- Value of Tunnel-Private-Group-ID must be a string of
ASCII chars in the range '0' - '9', which is interpreted as a
decimal string representing the VLAN ID. Leading '0's are
discarded. The final value must be in the range [1; 4095].
Guest VLAN Enabled
190
When Guest VLAN is both globally enabled and enabled
(checked) for a given port, the switch considers moving the
port into the Guest VLAN according to the rules outlined
below.
This option is only available for EAPOL-based modes, i.e.:
• Port-based 802.1X
• Single 802.1X
• Multi 802.1X
For trouble-shooting VLAN assignments, use the "Monitor
→ VLANs →VLAN Membership and VLAN Port" pages.
These pages show which modules have (temporarily)
overridden the current Port VLAN configuration.
Guest VLAN Operation:
When a Guest VLAN enabled port's link comes up, the
switch starts transmitting EAPOL Request Identity frames.
If the number of transmissions of such frames exceeds Max.
Reauth. Count and no EAPOL frames have been received.
In the meanwhile, the switch considers entering the Guest
VLAN. The interval between the transmission of EAPOL
Request Identity frames is configured with EAPOL
Timeout. If Allow Guest VLAN if EAPOL Seen is enabled,
the port will now be placed in the Guest VLAN. If disabled,
the switch will first check its history to see if an EAPOL
frame has previously been received on the port (this history
is cleared if the port link goes down or the port's Admin
State is changed), and if not, the port will be placed in the
Guest VLAN. Otherwise it will not move to the Guest
VLAN, but continue transmitting EAPOL Request Identity
frames at the rate given by EAPOL Timeout.
Once in the Guest VLAN, the port is considered
VigorSwitch P2261 User’s Guide
authenticated, and all attached clients on the port are
allowed access on this VLAN. The switch will not transmit
an EAPOL Success frame when entering the Guest VLAN.
While in the Guest VLAN, the switch monitors the link for
EAPOL frames, and if one such frame is received, the
switch immediately takes the port out of the Guest VLAN
and starts authenticating the supplicant according to the port
mode. If an EAPOL frame is received, the port will never be
able to go back into the Guest VLAN if the "Allow Guest
VLAN if EAPOL Seen" is disabled.
Port State
The current state of the port. It can undertake one of the
following values:
Globally Disabled: NAS is globally disabled.
Link Down: NAS is globally enabled, but there is no link on
the port.
Authorized: The port is in Force Authorized or a
single-supplicant mode and the supplicant is authorized.
Unauthorized: The port is in Force Unauthorized or a
single-supplicant mode and the supplicant is not
successfully authorized by the RADIUS server.
X Auth/Y Unauth: The port is in a multi-supplicant mode.
Currently X clients are authorized and Y are unauthorized.
Restart
Two buttons are available for each row. The buttons are
only enabled when authentication is globally enabled and
the port's Admin State is in an EAPOL-based or
MAC-based mode.
Clicking these buttons will not cause settings changed on
the page to take effect.
Reauthenticate: Schedules a reauthentication whenever the
quiet-period of the port runs out (EAPOL-based
authentication). For MAC-based authentication,
reauthentication will be attempted immediately.
The button only has effect for successfully authenticated
clients on the port and will not cause the clients to get
temporarily unauthorized.
Reinitialize: Forces a reinitialization of the clients on the
port and thereby a reauthentication immediately. The clients
will transfer to the unauthorized state while the
reauthentication is in progress.

2.4.18 AAA – General Setup
Function name:
AAA – General Setup
Function description:
The function uses an AAA (Authentication, Authorization, Accounting) server to provide
access control to your network. The AAA server can be a TACACS+ or RADIUS server to
create and manage objects that contain settings for using AAA servers.
The function describes how to configure AAA setting of TACACS+ or RADIUS server.
Parameters description:
Common Server Configuration
Timeout
The Timeout, which can be set to a number between 3 and
3600 seconds, is the maximum time to wait for a reply from
a server.
If the server does not reply within this timeframe, we will
consider it to be dead and continue with the next enabled
server (if any).
RADIUS servers are using the UDP protocol, which is
unreliable by design. In order to cope with lost frames, the
timeout interval is divided into 3 subintervals of equal
length. If a reply is not received within the subinterval, the
request is transmitted again. This algorithm causes the
RADIUS server to be queried up to 3 times before it is
considered to be dead.
Dead Time
The Dead Time, which can be set to a number between 0
and 3600 seconds, is the period during which the switch
will not send new requests to a server that has failed to
respond to a previous request. This will stop the switch
from continually trying to contact a server that it has already
determined as dead.
Setting the Dead Time to a value greater than 0 (zero) will
VigorSwitch P2261 User’s Guide
195
enable this feature, but only if more than one server has
been configured.
TACACS + Authorization and Accounting Configuration
Authorization
Every CLI commands will be authorized by
TACACS+ server when enable. The authorization
table on the TACACS+ server is able to configure
which CLI command can pass successfully. For
example, TACACS+ server is set to accept STP
command but deny VLAN command. The server will
block the command related to STP which entered by
user, but it can allow VLAN command to configure
successfully when user enter VLAN command.
Fallback to Local
Authorization
Enable to allow the user who typed wrong account or
password to login successfully when the user account
is on the local authorization list of the local switch. For
example, when user entered the wrong account or
password, TACACS+ server will refer to the account
information on the local end of switch. If the account is
recorded on the local switch, the user will be
authorized to login with the privilege level set on the
local switch.
Accounting
Enable to record all the command users entered. All
the log data will be recorded on the server when
enable. For instance, login time, log out time, IGMP
setting, VLAN setting, etc.

retransmitted to the RADIUS authentication server.
Pending Requests
The number of RADIUS Access-Request packets
destined for the server that have not yet timed out or
received a response. This variable is incremented when
an Access-Request is sent and decremented due to
receipt of an Access-Accept, Access-Reject,
Access-Challenge, timeout, or retransmission.
Timeouts
The number of authentication timeouts to the server.
After a timeout, the client may retry to the same server,
send to a different server, or give up. A retry to the
same server is counted as a retransmit as well as a
timeout. A send to a different server is counted as a
Request as well as a timeout.
IP Address
IP address and UDP port for the authentication server
in question.
State
Shows the state of the server. It takes one of the
following values:
Disabled: The selected server is disabled.
Not Ready: The server is enabled, but IP
communication is not yet up and running.
Ready: The server is enabled, IP communication is up

2.4.21 Port Security – Limit Control
Function name:
Port Security – Limit Control
Function description:
The function shows you how to configure the Port Security settings of the Switch. You can
use the Port Security feature to restrict input to an interface by limiting and identifying
MAC addresses.
Parameters description:
System Configuration
Mode
Indicates if Limit Control is globally enabled or disabled on
the switchstack. If globally disabled, other modules may
still use the underlying functionality, but limit checks and
corresponding actions are disabled.
Aging Enabled
If checked, secured MAC addresses are subject to aging as
discussed under Aging Period.
Aging Period
If Aging Enabled is checked, then the aging period is
controlled with this input. If other modules are using the
underlying port security for securing MAC addresses, they
may have other requirements to the aging period. The
underlying port security will use the shorter requested aging
period of all modules that use the functionality.
The Aging Period can be set to a number between 10 and
10,000,000 seconds.
To understand why aging may be desired, consider the
following scenario: Suppose an end-host is connected to a
VigorSwitch P2261 User’s Guide
201
3rd party switch or hub, which in turn is connected to a port
on this switch on which Limit Control is enabled. The
end-host will be allowed to forward if the limit is not
exceeded.
Now suppose that the end-host logs off or powers down. If
it wasn't for aging, the end-host would still take up
resources on this switch and will be allowed to forward. To
overcome this situation, enable aging. With aging enabled, a
timer is started once the end-host gets secured. When the
timer expires, the switch starts looking for frames from the
end-host, and if such frames are not seen within the next
Aging Period, the end-host is assumed to be disconnected,
and the corresponding resources are freed on the switch.
Port Configuration
202
Port
The port number to which the configuration below applies.
Mode
Controls whether Limit Control is enabled on this port. Both
this and the Global Mode must be set to Enabled for Limit
Control to be in effect. Notice that other modules may still
use the underlying port security features without enabling
Limit Control on a given port.
Limit
The maximum number of MAC addresses that can be
secured on this port. This number cannot exceed 1024. If
the limit is exceeded, the corresponding action is taken.
The stackswitch is "born" with a total number of MAC
addresses from which all ports draw whenever a new MAC
address is seen on a Port Security-enabled port. Since all
ports draw from the same pool, it may happen that a
configured maximum cannot be granted, if the remaining
ports have already used all available MAC addresses.
Action
If Limit is reached, the switch can take one of the following
actions:
None: Do not allow more than Limit MAC addresses on the
port, but take no further action.
Trap: If Limit + 1 MAC addresses are seen on the port, send
an SNMP trap. If Aging is disabled, only one SNMP trap
will be sent, but with Aging enabled, new SNMP traps will
be sent every time the limit gets exceeded.
Shutdown: If Limit + 1 MAC addresses is seen on the port,
shut down the port. This implies that all secured MAC
addresses will be removed from the port, and no new
address will be learned. Even if the link is physically
disconnected and reconnected on the port (by disconnecting
the cable), the port will remain shut down. There are three
ways to re-open the port:
1) Boot the stack or elect a new master the switch,
2) Disable and re-enable Limit Control on the port or the
stackswitch,
3) Click the Reopen button.
Trap & Shutdown: If Limit + 1 MAC addresses is seen on
the port, both the "Trap" and the "Shutdown" actions
VigorSwitch P2261 User’s Guide
described above will be taken.
State
This column shows the current state of the port as seen from
the Limit Control's point of view. The state takes one of
four values:
Disabled: Limit Control is either globally disabled or
disabled on the port.
Ready: The limit is not yet reached. This can be shown for
all actions.
Limit Reached: Indicates that the limit is reached on this
port. This state can only be shown if Action is set to None
or Trap.
Shutdown: Indicates that the port is shut down by the Limit
Control module. This state can only be shown if Action is
set to Shutdown or Trap & Shutdown.
Re-open Button
If a port is shutdown by this module, you may reopen it by
clicking this button, which will only be enabled if this is the
case. For other methods, refer to Shutdown in the Action
section.
Note that clicking the reopen button causes the page to be

2.4.22 Port Security – Switch Status
Function name:
Port Security – Switch Status
Function description:
This function shows the Port Security status. Port Security is a module with no direct
configuration. Configuration comes indirectly from other modules - the user modules.
When a user module has enabled port security on a port, the port is set-up for
software-based learning. In this mode, frames from unknown MAC addresses are passed on
to the port security module, which in turn asks all user modules whether to allow this new
MAC address to forward or block it. For a MAC address to be set in the forwarding state,
all enabled user modules must unanimously agree on allowing the MAC address to forward.
If only one chooses to block it, it will be blocked until that user module decides otherwise.
The status page is divided into two sections - one with a legend of user modules and one
with the actual port status.

State
Shows the current state of the port. It can take one of four
values:
Disabled: No user modules are currently using the Port
Security service.
Ready: The Port Security service is in use by at least one
user module, and is awaiting frames from unknown MAC
addresses to arrive.
Limit Reached: The Port Security service is enabled by at
least the Limit Control user module, and that module has
indicated that the limit is reached and no more MAC
addresses should be taken in.
Shutdown: The Port Security service is enabled by at least
the Limit Control user module, and that module has
indicated that the limit is exceeded. No MAC addresses can
be learned on the port until it is administratively re-opened
on the Limit Control configuration Web-page.

Function name:
Port Security – Port Status
Function description:
The function shows the MAC addresses secured by the Port Security module. Port Security
is a module with no direct configuration. Configuration comes indirectly from other
modules - the user modules. When a user module has enabled port security on a port, the
port is set-up for software-based learning. In this mode, frames from unknown MAC
addresses are passed on to the port security module, which in turn asks all user modules
whether to allow this new MAC address to forward or block it. For a MAC address to be
set in the forwarding state, all enabled user modules must unanimously agree on allowing
the MAC address to forward. If only one chooses to block it, it will be blocked until that
user module decides otherwise.
Parameters description:
MAC Address & VLAN

ID
no MAC addresses are learned, a single row stating "No
MAC addresses attached" is displayed.
State
Indicates whether the corresponding MAC address is
blocked or forwarding. In the blocked state, it will not be
allowed to transmit or receive traffic.
Time of Addition
Shows the date and time when this MAC address was first
seen on the port.
Age/Hold
If at least one user module has decided to block this MAC
address, it will stay in the blocked state until the hold time
(measured in seconds) expires. If all user modules have
decided to allow this MAC address to forward, and aging is
enabled, the Port Security module will periodically check
that this MAC address still forwards traffic. If the age
period (measured in seconds) expires and no frames have
been seen, the MAC address will be removed from the
MAC table. Otherwise a new age period will begin.
If aging is disabled or a user module has decided to hold the
MAC address indefinitely, a dash (-) will be shown.

2.5.12 Diagnostics – VeriPHY
Function name:
Diagnostics – VeriPHY
Function description:
The function is used for running the VeriPHY Cable Diagnostics. Press to run the
diagnostics. This will take approximately 5 seconds. If all ports are selected, this can take
approximately 15 seconds. When completed, the page refreshes automatically, and you can
view the cable diagnostics results in the cable status table. Note that VeriPHY is only
accurate for cables of length 7 -140 meters.10 and 100 Mbps ports will be linked down
while running VeriPHY. Therefore, running VeriPHY on a 10 or 100 Mbps management
port will cause the switch to stop responding until VeriPHY is complete.
Parameters description:
Port
The port where you are requesting VeriPHY Cable
Diagnostics.
Cable Status
Port: Port number.
Pair: The status of the cable pair.
Length: The length (in meters) of the cable pair.
After finished the above settings, click Start to perform the Ping job.

3.2 Q & A
1. Computer A can connect to Computer B, but cannot connect to
Computer C through the Managed Switch.
¾
The network device of Computer C may fail to work. Please check the link/act status
of Computer C on the LED indicator. Try another network device on this connection.
¾
The network configuration of Computer C may be something wrong. Please verify the
network configuration on Computer C.
2. The uplink connection function fails to work.
¾
The connection ports on another must be connection ports. Please check if connection
ports are used on that Managed Switch.
¾
Please check the uplink setup of the Managed Switch to verify the uplink function is
enabled.
3. The console interface cannot appear on the console port
connection.
¾
The COM port default parameters are [Baud Rate: 115200, Data Bits: 8, Parity Bits:
None, Stop Bit: A, Flow Control: None]. Please check the COM port property in the
terminal program. And if the parameters are changed, please set the COM
configuration to the new setting.

Check the RS-232 cable is connected well on the console port of the Managed Switch
and COM port of PC.
¾
Check if the COM of the PC is enabled.
4. How to configure the Managed Switch?
The “Hyperterm” is the terminal program in Win95/98/NT. Users can also use any other
terminal programs in Linux/Unix to configure the Managed Switch. Please refer to the user
guide of that terminal program. But the COM port parameters (baud rate/ data bits/ parity
bits/ flow control) must be the same as the setting of the console port of the Managed
Switch.
