CHAPTER
1
Introduction
This chapter introduces and shows you how to access the EMS (Element Management
System).
1.1 Overview
The Element Management System (EMS) retrieves management information from switches
using SNMP protocol.
An EMS is composed of Network Elements (NE) that represent resources in a Network
Management System (NMS). The network elements can represent a physical piece of
equipment on the network, the components of a device on the network, or parts of the network
itself.
The following figure shows a network example.
Figure 1 EMS Network Example
1.1.1 EMS Components
The EMS consists of two components: the EMS server and the EMS remote client. You must
install the EMS server, which provides all the functions to use the EMS. You can install the
EMS remote client on other computers if you want to use EMS on them as well.
You can send SNMP messages to managed devices from an EMS remote client (RC) or
through the EMS server (S). The following figure shows a network example.

1.1.2 SNMPc Network Manager
SNMPc is network management software produced by Castle Rock.
You must have SNMPc properly installed before you can use the EMS. Refer to the appendix
in this User’s Guide; go to the Castle Rock web site at www.castlerock.com or see your
SNMPc user's guide.

2.3 Database Management
The following information is stored in the EMS database.
• Event and access logs
• EMS configuration
• Device configuration and status information
Use the Database Management screens to back up logs and EMS and SNMPc configurations
and restore selected backed up files.
2.3.1 Database Synchronization
The EMS is able to synchronize the device tree and device status information with SNMPc.
This means that when you add a device in EMS, the same change also applies in SNMPc and
the new device icon is created in both the EMS and SNMPc screens. In addition, device status
changes are reflected in both the EMS and the SNMPc screens.
EMS database is synchronized:
• when you launch the Switch Manager screen.
• when you click Map > Sync Map DB in EMS.
• automatically everyday at mid-night (this schedule is not configurable).
2.3.2 Filename Convention
The EMS follows a pre-defined naming convention for backup files. Data is backed up in plain
text format with a “txt” filename extension. The general structure of the filename is
<type>.txt (for example, AccessLog.txt).

5.2 STP/RSTP
(R)STP detects and breaks network loops and provides backup links between switches,
bridges or routers. It allows a switch to interact with other (R)STP -compliant switches in your
network to ensure that only one path exists between any two stations on the network.
"
In this user’s guide, “STP” refers to both STP and RSTP.
5.2.1 STP Terminology
The root bridge is the base of the spanning tree; it is the bridge with the lowest identifier value
(MAC address).
Path cost is the cost of transmitting a frame onto a LAN through that port. It is assigned
according to the speed of the link to which a port is attached. The slower the media, the higher
the cost - see the next table.

On each bridge, the root port is the port through which this bridge communicates with the root.
It is the port on this switch with the lowest path cost to the root (the root path cost). If there is
no root port, then this switch has been accepted as the root bridge of the spanning tree
network.
For each LAN segment, a designated bridge is selected. This bridge has the lowest cost to the
root among the bridges connected to the LAN.
5.2.2 STP Port States
STP assigns five port states (see next table) to eliminate packet looping. A bridge port is not
allowed to go directly from blocking state to forwarding state so as to eliminate transient
loops.

Forwarding Delay
(second)
This is the time (in seconds) the root switch will wait before changing states (that
is, listening to learning to forwarding).
Cost to Bridge
This is the path cost from the root port on this switch to the root switch.
Port ID
This is the priority and number of the port on the switch through which this switch
must communicate with the root of the spanning tree.

6.1 Template Overview
A template is a pre-configured set of configuration settings. Templates allow you to configure
device VLANs, IGMP filers and multicast groups efficiently. The template can then be
uploaded to one or more devices thus removing the need to configure the corresponding
settings for each device.
6.2 VLAN Template

System Configuration
This chapter shows you how to view general system information, configure SNMP, remote
management and time setup.
13.1 System Info
See Section 3.9 on page 48 for information about the switch.
13.2 SNMP
Simple Network Management Protocol is a protocol used for exchanging management
information between network switches. SNMP is a member of TCP/IP protocol suite. A
manager station can manage and monitor the switch through the network via SNMP version
2c. The next figure illustrates an SNMP management operation. SNMP is only available if
TCP/IP is configured.
Figure 89 SNMP Management Model
An SNMP managed network consists of two main components: agents and a manager.
NetAtlas Workgroup User’s Guide
131
Chapter 13 System Configuration
An agent is a management software module that resides in a managed switch (your Ethernet
switch). An agent translates the local management information from the managed switch into a
form compatible with SNMP. The manager is the console through which network
administrators perform network management functions. It executes applications that control
and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a switch. Examples of variables include such as number of
packets received, node port status etc. A Management Information Base (MIB) is a collection
of managed objects. SNMP allows a manager and agents to communicate for the purpose of
accessing these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The
manager issues a request and the agent returns responses using the following protocol
operations:
Table 55 SNMP Commands
COMMAND
DESCRIPTION
Get
Allows the manager to retrieve an object variable from the agent.
GetNext
Allows the manager to retrieve the next object variable from a table or list within an
agent. In SNMP, when a manager wants to retrieve all elements of a table from an
agent, it initiates a Get operation, followed by a series of GetNext operations.
Set
Allows the manager to set values for object variables within an agent.
Trap
Used by the agent to inform the manager of some events.
See the switch User’s Guide for a list of supported traps.
13.2.1 Configuring SNMP
To open display the SNMP Config screen, right-click on a switch in the Device List Panel,
and click Configuration > System Configuration > SNMP Conf..

Switch Configuration
This chapter shows how to configure switch settings such as priority queuing, STP, link
aggregation and GARP timer.
14.1 Switch Setup
Use the switch setup screen to set a VLAN type, a queuing method and enable or disable
features in the Active Control panel.
To open this screen, right-click on the switch in the Device List Panel, and click
Configuration > Switch Configuration > Switch Setup.

The following table describes the related labels in the screen.
Table 64 Switch Configuration: Switch Setup
LABEL
DESCRIPTION
VLAN Type
Choose 802.1Q or Port Based from the drop-down list box. The VLAN
Setup screen changes depending on whether you choose 802.1Q or Port
Based VLAN type in this screen. See Section 16.3 on page 165 and the
VLAN chapter for more information on VLANs.
MAC Address Aging Time
MAC address learning reduces outgoing traffic broadcasts. For MAC
address learning to occur on a port, the port must be active.
Enter a time from 10 to 3000 seconds. This is how long all dynamically
learned MAC addresses remain in the MAC address table before they age
out (and must be relearned).
Queuing Method
Select a queuing method. Choices vary depending on your switch
models.
Strict Priority Queuing (SPQ) services queues based on priority only.
When the highest priority queue empties, traffic on the next highestpriority queue begins. The default queuing method is Strictly Priority.
Weighted Fair Scheduling is used to guarantee each queue's minimum
bandwidth based on their bandwidth portion (weight) (the number you
configure in the Weight field). Queues with larger weights get more
guaranteed bandwidth than queues with smaller weights.
Weighted Round Robin Scheduling (WRR) services queues on a
rotating basis based on their queue weight (the number you select from
the drop-down list box for the corresponding queue). Queues with larger
weights get more service than queues with smaller weights.
FE Port SPQ Enable
This field is applicable only when you select WFQ or WRR.
Select a queue (Q0 to Q7) to have the switch use Strictly Priority to
service the subsequent queue(s) after and including the specified queue
for the 10/100 Mbps Ethernet ports. For example, if you select Q5, the
switch services traffic on Q5, Q6 and Q7 using Strictly Priority.
Select None to always use WFQ or WRR for the 10/100 Mbps Ethernet
ports.
Q0-Q3
These fields are applicable only for switches that use WRR and for
switches that assign queue weights for the entire system (not per port).
Use the drop down list boxes to choose queue weights (1-15). Bandwidth
is divided across the different traffic queues according to their weights.
Broadcast Storm Control
These fields are not available on all switch models.
Set the fields below to configure traffic storm control.
Active
Select Active to enable traffic storm control on the switch.
Storm Control Type
Specify the traffic type in this field. Select Broadcast Only, Broadcast
and multicast, Broadcast and unknown unicast or Broadcast,
multicast and unknown unicast from the drop-down list box.
Packet Limit
From the drop-down list box, select the number of packets (of the type
chosen above) a port can receive per second.

DESCRIPTION
GVRP
Select the check box to permit VLANs groups beyond the local switch on
this port. GVRP (GARP VLAN Registration Protocol) is a registration
protocol that defines a way for switches to register necessary VLAN
members on ports across the network.
802.1q Port Isolation
Port Isolation allows each port to communicate with the CPU port, uplink
ports and stacking ports (if available) but not communicate with each
other. This option is the most limiting but also the most secure.
802.1q Ingress Check
Select this check box to set the switch to discard incoming frames for
VLANs that do not have this port as a member
VLAN Stacking
Select the check box to enable VLAN stacking.
In the SP TPID drop-down list box, select a standard Ethernet type code
to identify the frame and indicate whether the frame carries IEEE 802.1Q
tag information. Or select Others and then enter a four-digit hexadecimal
number from 0x0000 to 0xFFFF. 0x denotes a hexadecimal number. It
does not have to be typed in the Others field.

14.2 Priority Queue
Queuing is used to help solve performance degradation when there is network congestion.
Configure queuing algorithms for outgoing traffic in the Switch Setup screen. Queuing
algorithms allow switches to maintain separate queues for packets from each individual source
or flow and prevent a source from monopolizing the bandwidth.
Follow the steps below to configure priority queuing.

LABELS
DESCRIPTION
Priority Queue
Assignment
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer
frame that contains bits to define class of service. Frames without an explicit priority
tag are given the default priority of the ingress port. Use these fields to configure the
priority level-to-physical queue mapping. On the switch, traffic assigned to higher
index queues gets through faster while traffic in lower index queues is dropped if the
network is congested.
Priority Level
The following descriptions are based on the traffic types defined in the IEEE 802.1D
standard (which incorporates 802.1p). Select a level from the drop-down list box(es).
Level 7
Typically used for network control traffic such as router configuration messages.
Level 6
Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations
in delay).
Level 5
Typically used for video that consumes high bandwidth and is sensitive to jitter.
Level 4
Typically used for controlled load, latency-sensitive traffic such as SNA (Systems
Network Architecture) transactions.
Level 3
Typically used for “excellent effort” or better than best effort and would include
important business traffic that can tolerate some delay.
Level 2
This is for “spare bandwidth”.
Level 1
This is typically used for non-critical “background” traffic such as bulk transfers that
are allowed but that should not affect other applications and users.
Level 0
Typically used for best-effort traffic.

14.3 Multiple/ Rapid STP Configuration
STP (Spanning Tree Protocol) detects and breaks network loops and provides backup links
between switches, bridges or routers. It allows a device to interact with other STP-aware
devices in your network to ensure that only one path exists between any two stations on the
network. Refer to the user’s guide that comes with your switch for more information.
Use the Multiple STP Conf. screen to configure STP and/or multiple STP settings on the
switch.
To open this screen, right-click on the switch in the Device List Panel, and click
Configuration > Switch Configuration > Multiple STP Conf..

Bridge Priority
Priority is used in determining the root device, root port and designated port. The
device with the highest priority (lowest numeric value) becomes the RSTP root device.
If all devices have the same priority, the device with the lowest MAC address will then
become the root device. The allowed range is 0 to 65535 (32768 is the default).
The lower the numeric value you assign, the higher the priority for this bridge.
Priority determines the root bridge, which in turn determines Hello Time, Max Age
and Forward Delay.
NetAtlas Workgroup User’s Guide
147
Chapter 14 Switch Configuration
Table 66 Switch Configuration: Multiple STP Conf. (continued)
LABEL
DESCRIPTION
Hello Time
This is the maximum time (in seconds) a device can wait without receiving a BPDU
before attempting to reconfigure. All device ports (except for designated ports) should
receive BPDUs at regular intervals. Any port that ages out STP information (provided
in the last BPDU) becomes the designated port for the attached LAN. If it is a root
port, a new root port is selected from among the device ports attached to the network.
The allowed range is 6 to 40 seconds (20 is the default).
Max Age
This is the time interval in seconds between BPDU (Bridge Protocol Data Units)
configuration message generations (by all devices in RSTP or the root device in STP).
The allowed range is 1 to 10 seconds (2 is the default).
Forwarding
Delay
This is the maximum time (in seconds) a device will wait before changing states. This
delay is required because every device must receive information about topology
changes before it starts to forward frames. In addition, each port needs time to listen
for conflicting information that would make it return to a blocking state; otherwise,
temporary data loops might result. The allowed range is 4 to 30 seconds (15 is the
default).

14.4 Link Aggregation
Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity
link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed
links than to under-utilize a high-speed, but more costly, single-port link.
However, the more ports you aggregate then the fewer available ports you have. A link
aggregation group is one logical link containing multiple ports.
The first port must be physically connected when forming a trunk group.
148
NetAtlas Workgroup User’s Guide
Chapter 14 Switch Configuration
14.4.1 Dynamic Link Aggregation
This feature is not available on all models.
The switch adheres to the IEEE 802.3ad standard for static and dynamic (LACP) port
trunking.
The switch supports the link aggregation IEEE 802.3ad standard. This standard describes the
Link Aggregate Control Protocol (LACP), which is a protocol that dynamically creates and
manages trunk groups.
When you enable LACP link aggregation on a port, the port can automatically negotiate with
the ports at the remote end of a link to establish trunk groups. LACP also allows port
redundancy, that is, if an operational port fails, then one of the “standby” ports become
operational without user intervention
Please note that:
• You must connect all ports point-to-point to the same Ethernet switch and configure the
ports for LACP trunking.
• LACP only works on full-duplex links.
• All ports in the same trunk group must have the same media type, speed, duplex mode and
flow control settings.
Configure trunk groups or LACP before you connect the Ethernet switch to avoid causing
network topology loops.
14.4.2 Link Aggregation ID
LACP aggregation ID consists of the following information:

VLAN
This chapter describes how to view VLAN status, add and edit VLANs and how to use the
VLAN template. The type of screen you see here depends on the VLAN Type you selected in
the Switch Setup screen.
15.1 Introduction to VLANs
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Devices on a logical network belong to one group. A device can
belong to more than one group. With VLAN, a device cannot directly talk to or hear from
devices that are not in the same group(s); the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security
among the subscribers. When properly configured, VLAN prevents one subscriber from
accessing the network resources of another on the same LAN, thus a user will not see the
printers and hard disks of another user in the same building.
VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast
packets go to each and every individual port. With VLAN, all broadcasts are confined to a
specific broadcast domain.
Note that VLAN is unidirectional; it only governs outgoing traffic.

15.3 Introduction to Port-based VLANs
Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.

DESCRIPTION
Timeout
(seconds)
The text box displays how long (in seconds) an SNMP request times out. You may
change the timeout by typing a new number in the text box and then clicking the
Apply button.
Setting Wizard Choose from All connected or Port isolation.
All connected means all ports can communicate with each other, that is, there are no
virtual LANs. All incoming and outgoing ports are selected. This option is the most
flexible but also the least secure.
Port isolation means that each port can only communicate with the CPU
management port and cannot communicate with each other. All incoming ports are
selected while only the CPU outgoing port is selected. This option is the most limiting
but also the most secure.
After you make your selection, click Apply to display the screens as mentioned
above. You can still customize these settings by adding/deleting incoming or outgoing
ports, but you must also click Apply at the bottom of the screen.
162
Incoming
These are the ingress ports; an ingress port is an incoming port, that is, a port through
which a data packet enters. If you wish to allow two subscriber ports to talk to each
other, you must define the ingress port for both ports. The numbers in the top row
denote the incoming port for the corresponding port listed on the left (its outgoing
port). CPU refers to the switch management port. By default it forms a VLAN with all
Ethernet ports. If it does not form a VLAN with a particular port then the switch cannot
be managed from that port.
Outgoing
These are the egress ports; an egress port is an outgoing port, that is, a port through
which a data packet leaves. If you wish to allow two subscriber ports to talk to each
other, you must define the egress port for both ports. CPU refers to the switch
management port. By default it forms a VLAN with all Ethernet ports. If it does not
form a VLAN with a particular port then the switch cannot be managed from that port.

Ethernet Port Configuration
This chapter shows how to configure the Ethernet port settings.
16.1 Overview
Use the Ethernet Port Configuration screens to set port-related settings (such as port VLAN,
STP and security, etc.).
Once you configure a feature on a port, you must enable that feature on the switch in the
Switch Setup screen.
16.2 Port Setup
Use the Port Setup screen to activate and configure switch port settings.
To open this screen, right-click on the switch in the Device List Panel, and click
Configuration > Ethernet Port > Port Setup. Then select a device and the port(s) to which
you want to apply this configuration.

Chapter 16 Ethernet Port Configuration
The following table describes the fields in this screen.
Table 80 Ethernet Port Configuration: Port Setup
LABEL
DESCRIPTION
Active
Select this check box to enable a port. The factory default for all ports is enabled. A
port must be enabled for data transmission to occur.
Type
This field displays the port type and port speed.
Port Name
Enter a descriptive name for identification purposes.
Speed/
Duplex
Select the speed and the duplex mode of the Ethernet connection on this port. Choices
are Auto, 10M/Half Duplex, 10M/Full Duplex, 100M/Half Duplex, 100M/Full Duplex
and 1000M/Full Duplex (for Gigabit/mini-GBIC ports only).
Selecting Auto (auto-negotiation) makes one Ethernet port able to negotiate with a
peer automatically to obtain the connection speed and duplex mode that both ends
support. When auto-negotiation is turned on, an Ethernet port on the switch negotiates
with the peer automatically to determine the connection speed and duplex mode. If the
peer Ethernet port does not support auto-negotiation or turns off this feature, the
switch determines the connection speed by detecting the signal on the cable and using
half duplex mode. When the switch’s auto-negotiation is turned off, an Ethernet port
uses the pre-configured speed and duplex mode when making a connection, thus
requiring you to make sure that the settings of the peer Ethernet port are the same in
order to connect.
Flow Control
A concentration of traffic on a port decreases port bandwidth and overflows buffer
memory causing packet discards and frame losses. Flow Control is used to regulate
transmission of signals to match the bandwidth of the receiving port. The switch uses
IEEE 802.3x flow control in full duplex mode and backpressure flow control in half
duplex mode.
IEEE 802.3x flow control is used in full duplex mode to send a pause signal to the
sending port, causing it to temporarily stop sending signals when the receiving port
memory buffers fill. Back Pressure flow control is typically used in half duplex mode to
send a "collision" signal to the sending port (mimicking a state of packet collision)
causing the sending port to temporarily stop sending signals and resend later. Select
Flow Control to enable it.
802.1p
Priority
The switch uses this priority value for incoming frames without an IEEE 802.1p priority
queue tag. The switch uses this priority value internally and does not add an IEEE
802.1p priority tag.
Intrusion Lock Select the Intrusion Lock check box to enable this security feature on a selected port
on the switch. If an Ethernet cable is disconnected from the port, intrusion locking
prevents access once a cable is reconnected. This limits risk from unauthorized
access such as hacking.
Note: You cannot access a port with intrusion locking enabled after a
cable is disconnected and then reconnected. You must clear
and re-select the Intrusion Lock check box to allow access to
the port again.
BPDU
Control
164
Configure the way to treat BPDUs received on this port. You must activate bridging
control protocol transparency in the Switch Setup screen first.
Select Peer to process any BPDU (Bridge Protocol Data Units) received on this port.
Select Tunnel to forward BPDUs received on this port.
Select Discard to drop any BPDU received on this port.
Select Network to process a BPDU with no VLAN tag and forward a tagged BPDU.

DESCRIPTION
Jumbo Frame Jumbo frames are used to forward non-standard packet sizes on your network. These
frames can deliver frames of up to 9216 bytes instead of standard Ethernet frames of
1522 bytes. Fewer packets are required for large data transfer, improving traffic
throughput on the port.
Select this option to allow a port to send and receive jumbo frames.
Note: The peer device must also support non-standard packet traffic.
PD
A powered device (PD) is a device such as an access point or a switch, that supports
PoE (Power over Ethernet) so that it can receive power from another device through a
10/100Mbps Ethernet port.
Select the check box to allow a powered device (connected to the port) to receive
power from the switch.

DESCRIPTION
Ingress
This feature is not supported on all models.
If this check box is selected for a port, the device discards incoming frames for VLANs
that do not include this port in its member set.
PVID
Each port on the switch is capable of passing tagged or untagged frames. To forward a
frame from an IEEE 802.1Q VLAN-unaware switch to an IEEE 802.1Q VLAN-aware
switch, the switch first decides where to forward the frame, and then inserts a VLAN tag
reflecting the default ingress port's VLAN ID, the PVID. The default PVID is VLAN 1 for
all ports, but this can be changed to any number between 1 and 4094.
GVRP
Select the check box to permit VLAN groups beyond the local switch on this port. GVRP
(GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to register necessary VLAN members on ports across the network.
Acceptable
Frame Type
Specify the type of frames allowed on a port. Choices are All and Tag Only. Select All
to accept all frames with untagged or tagged frames on this port. This is the default
setting. Select Tag Only to accept only tagged frames on this port. All untagged frames
are dropped.
VLAN
Trunking

Timeout
Timeout is the time interval between the individual port exchanges of LACP packets in
order to check that the peer port in the trunk group is still up. If a port does not
respond after three tries, then it is deemed to be “down” and is removed from the
trunk. Set a short timeout (one second) for busy trunked links to ensure that disabled
ports are removed from the trunk group as soon as possible. Select from 1 second to
30 seconds.

16.7 Port Mirroring
Port mirroring allows you to copy traffic going from one or all ports to another or all ports in
order that you can examine the traffic from the mirror port (the port you copy the traffic to)
without interference.
You must first select a monitor port. A monitor port is a port that copies the traffic of another
port. After you select a monitor port, configure a mirroring rule in the related fields.

16.8 VLAN Stacking
A service provider can use VLAN stacking to allow it to distinguish multiple customers
VLANs, even those with the same (customer-assigned) VLAN ID, within its network.
Use VLAN stacking to add an outer VLAN tag to the inner IEEE 802.1Q tagged frames that
enter the network. By tagging the tagged frames ("double-tagged" frames), the service
provider can manage up to 4,094 VLAN groups with each group containing up to 4,094
customer VLANs. This allows a service provider to provide different service, based on
specific VLANs, for many different customers.
A service provider's customers may require a range of VLANs to handle multiple applications.
A service provider's customers can assign their own inner VLAN tags on ports for these
applications. The service provider can assign an outer VLAN tag for each customer.
Therefore, there is no VLAN tag overlap among customers, so traffic from different customers
is kept separate.
To open the VLAN Stacking screen, right-click on the switch in the Device List Panel, and
click Configuration > Ethernet Port > VLAN Stacking. Then select a device and the port(s)
to which you want to apply this configuration.

VLAN stacking tags. Anything you configure in SPVID and Priority is ignored.
Select Access Port to have the switch add the SP TPID tag to all incoming frames
received on this port. Select Access Port for ingress ports at the edge of the service
provider's network.
Select Tunnel Port (available for Gigabit ports only) for egress ports at the edge of the
service provider's network. In order to support VLAN stacking on a port, the port must be
able to allow frames of 1526 Bytes (1522 Bytes + 4 Bytes for the second tag) to pass
through it.
SPVID
SPVID is the service provider's VLAN ID (the outer VLAN tag). Enter the service provider
ID (from 1 to 4094) for frames received on this port. See the chapter on VLANs for more
background information on VLAN ID.

SPQ
Select SPQ (Strict Priority Queuing) to service queues based on priority only.
When the highest priority queue empties, traffic on the next highest-priority queue
begins. The default queuing method is Strictly Priority.
Weighted Fair Scheduling is used to guarantee each queue's minimum
bandwidth based on their bandwidth portion (weight) (the number you configure
in the Weight field). Queues with larger weights get more guaranteed bandwidth
than queues with smaller weights.
WRR
Select WRR (Weighted Round Robin Scheduling) to service queues on a rotating
basis based on their queue weight (the number you select from the drop-down list
box for the corresponding queue). Queues with larger weights get more service
than queues with smaller weights.
Apply
Click Apply to save the changes.
16.10 Protocol VLAN
Protocol based VLANs allow you to group traffic into logical VLANs based on the protocol
you specify. When an upstream frame is received on a port (configured for a protocol based
VLAN), the switch checks if a tag is added already and its protocol. The untagged packets of
the same protocol are then placed in the same protocol based VLAN. One advantage of using
protocol based VLANs is that priority can be assigned to traffic of the same protocol.
Note: Protocol based VLAN applies to un-tagged packets and is applicable only when
you use IEEE 802.1Q tagged VLAN.
To open the Protocol VLAN screen, right-click on the switch in the Device List Panel, and
click Configuration > Ethernet Port > Protocol VLAN. Then select a device and the port(s)
to which you want to apply this configuration.

level of service desired. This allows the intermediary DiffServ-compliant network devices to
handle the packets differently depending on the code points without the need to negotiate
paths or remember state information for every flow. In addition, applications do not have to
request a particular service or give advanced notice of where the traffic is going.

Multicast Configuration
This chapter shows you how to configure multicast settings and MVR (Multicast VLAN
Registration) groups.
17.1 Overview
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1
recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets
to just a group of hosts on the network.
IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish
membership in a multicast group - it is not used to carry user data. Refer to RFC 1112 and
RFC 2236 for information on IGMP versions 1 and 2 respectively.
17.1.1 IP Multicast Addresses
In IPv4, a multicast address allows a device to send packets to a specific group of hosts
(multicast group) in a different subnetwork. A multicast IP address represents a traffic
receiving group, not individual receiving devices. IP addresses in the Class D range (224.0.0.0
to 239.255.255.255) are used for IP multicasting. Certain IP multicast numbers are reserved by
IANA for special purposes (see the IANA web site for more information).
17.1.2 IGMP Snooping
A switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets
transferred between IP multicast routers/switches and IP multicast hosts to learn the IP
multicast group membership. It checks IGMP packets passing through it, picks out the group
registration information, and configures multicasting accordingly. IGMP snooping allows the
switch to learn multicast groups without you having to manually configure them.
The switch forwards multicast traffic destined for multicast groups (that it has learned from
IGMP snooping or that you have manually configured) to ports that are members of that
group. IGMP snooping generates no additional network traffic, allowing you to significantly
reduce multicast traffic passing through your switch.
For background information on IGMP filtering, refer to Section 6.3 on page 79.

17.3 MVR
Multicast VLAN Registration (MVR) is designed for applications (such as Media-on-Demand
(MoD)) that use multicast traffic across a service provider network.
MVR allows one single multicast VLAN to be shared among different subscriber VLANs on
the network. While isolated in different subscriber VLANs, connected devices can subscriber
to and unsubscribe from the multicast stream in the multicast VLAN. This improves
bandwidth utilization with reduced multicast traffic in the subscriber VLANs and simplifies
multicast group management.
You must enable IGMP snooping to use MVR. However, MVR only responds to IGMP join
and leave control messages from multicast groups that are configured under MVR. Join and
leave reports from other multicast groups are managed by IGMP snooping.
184
NetAtlas Workgroup User’s Guide
Chapter 17 Multicast Configuration
17.3.1 Types of MVR Ports
In MVR, a source port is a port on the switch that can send and receive multicast traffic in a
multicast VLAN while a receiver port can only receive multicast traffic. Once configured, the
switch maintains a forwarding table that matches the multicast stream to the associated
multicast group.
17.3.2 MVR Modes
You can set your switch to operate in either dynamic or compatible mode.
In dynamic mode, the switch sends IGMP leave and join reports through the source port(s) to
the other multicast devices (such as multicast routers or servers) in the multicast VLAN. This
allows the multicast devices to update the multicast forwarding table to forward or not forward
multicast traffic to the receiver ports.
In compatible mode, the switch does not send any IGMP reports through the source port(s). In
this case, you must manually configure the forwarding settings on the multicast devices in the
multicast VLAN.
Refer to the user’s guide that comes with your switch for more background information.

Configuration
Use this menu item to look at and configure RMON (Remote Network Monitor) on a switch.
18.1 RMON Overview
Similar to SNMP, RMON (Remote Network Monitor) allows you to gather and monitor
network traffic.
Both SNMP and RMON use an agent, known as a probe, which are software processes
running on network devices to collect information about network traffic and store it in a local
MIB (Management Information Base). With SNMP, a network manager has to constantly poll
the agent to obtain MIB information. With RMON, the probe is located on a remote device
(the MSC), so a network manager (the EMS) does not need to constantly poll the probe for
information. The probe communicates with the network manager via SNMP.
RMON groups contain detailed information about specific activities. The following table
describes the four RMON groups that your IES supports.

DiffServ is a class of service (CoS) model that marks packets so that they receive specific perhop treatment at DiffServ-compliant network devices along the route based on the application
types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the
level of service desired. This allows the intermediary DiffServ-compliant network devices to
handle the packets differently depending on the code points without the need to negotiate
paths or remember state information for every flow. In addition, applications do not have to
request a particular service or give advanced notice of where the traffic is going.
Enable this feature in the DiffServ screen. Click IP Configuration > DiffServ to display the

19.5 DHCP
DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual
computers to obtain TCP/IP configuration at start-up from a server. You can configure the
switch as a DHCP server or disable it. When configured as a server, the switch provides the
TCP/IP configuration for the clients. If you disable the DHCP service, you must have another
DHCP server on your LAN, or else the computer must be manually configured.
19.5.1 DHCP modes
Depending on your switch model, your switch can be configured as a DHCP server or DHCP
relay agent.
• If you configure the switch as a DHCP server, it will maintain the pool of addresses and
distribute them to your LAN computers.
• If there is an Ethernet device that performs the DHCP server function for your network,
then you can configure the switch as a DHCP relay agent. When the switch receives a
request from a computer on your network, it contacts the Ethernet device (the DHCP

19.5.3 Configuring DHCP Relay
Configure DHCP relay on the switch if the DHCP clients and the DHCP server are not in the
same subnet. During the initial IP address leasing, the switch helps to relay network
information (such as the IP address and subnet mask) between a DHCP client and a DHCP
server. Once the DHCP client obtains an IP address and can connect to the network, network
information renewal is done between the DHCP client and the DHCP server without the help
of the switch.
206
NetAtlas Workgroup User’s Guide
Chapter 19 IP Configuration
19.5.3.1 DHCP Relay Agent Information
The switch can add information to client DHCP requests that it relays to a DHCP server. This
helps provide authentication about the source of the requests. You can also specify additional
information for the switch to add to the client DHCP requests that it relays to the DHCP
server. Please refer to RFC 3046 for more details.
The DHCP relay agent information feature adds an Agent Information field to the option 82
field of the DHCP headers of client DHCP request frames that the switch relays to a DHCP
server. The following lists the DHCP relay agent option 82 information that the switch sends
to the DHCP server:
•
•
•
•
Slot ID (1 byte)
Port ID (1 byte)

19.6 DVMRP
DVMRP (Distance Vector Multicast Routing Protocol) is a protocol used for routing multicast
data within an autonomous system (AS). This DVMRP implementation is based on draft-ietfidmr-dvmrp-v3-10. DVMRP provides multicast forwarding capability to a layer 3 switch that
runs both the IPv4 protocol (with IP Multicast support) and the IGMP protocol. The DVMRP
metric is a hop count of 32.
IGMP is a protocol used for joining or leaving a multicast group. You must have IGMP
enabled when you enable DVMRP.
To open the DVMRP screen, right-click on a switch in the Device Panel list and click
Configuration > IP Configuration > DVMRP.

Table 115 IP Configuration: DVMRP
LABEL
DESCRIPTION
Active
Select Active to enable DVMRP on the switch. You should do this if you want the switch to
act as a multicast router.
Threshold
Threshold is the maximum time to live (TTL) value. TTL is used to limit the scope of
multicasting. You should reduce this value if you do not wish to flood Layer 3 devices
many hops away with multicast traffic. This applies only to multicast traffic this switch
sends out.
Index
Index is the DVMRP configuration for the IP routing domain defined under Network. The
maximum number of DVMRP configurations allowed is the maximum number of IP routing
domains allowed on the switch. See Section 13.8 on page 139 for more information on IP
routing domains.
Network
This is the IP routing domain IP address and subnet mask you set up in IP Setup.
VID
DVMRP cannot be enabled on the same VLAN group across different IP routing domains,
that is, you cannot have duplicate VIDs for different DVMRP configurations.
Active
Select Yes to enable DVMRP on this IP routing domain. Select No to disable this feature.

19.8 OSPF
OSPF (Open Shortest Path First) is a link-state protocol designed to distribute routing
information within an autonomous system (AS). An autonomous system is a collection of
networks using a common routing protocol to exchange routing information.
210
NetAtlas Workgroup User’s Guide

19.8.1 OSPF Autonomous Systems and Areas
An OSPF autonomous system can be divided into logical areas. Each area represents a group
of adjacent networks. All areas are connected to a backbone (also known as area 0). The
backbone is the transit area to route packets between two areas. A stub area, at the edge of an
AS, is not a transit area since there is only one connection to the stub area.
19.8.2 Interfaces and Virtual Links
An OSPF interface is a link between a layer 3 device and an OSPF network. An interface has
state information, an IP address and subnet mask associated with it. When you configure an
OSPF interface, you first set an interface to transmit OSPF traffic and add the interface to an
area.
You can configure a virtual link to establish/maintain connectivity between a non-backbone
area and the backbone. The virtual ink must be configured on both layer 3 devices in the nonbackbone area and the backbone.
19.8.3 Configuring Basic OSPF Settings

19.9 VRRP
Virtual Router Redundancy Protocol (VRRP), defined in RFC 2338, allows you to create
redundant backup gateways to ensure that the default gateway of a host is always available.
In VRRP, a virtual router (VR) represents a number of physical layer-3 devices. An IP address
is associated with the virtual router. A layer-3 device having the same IP address is the
preferred master router while the other Layer-3 devices are the backup routers. The master
router forwards traffic for the virtual router. When the master router becomes unavailable, a
backup router assumes the role of the master router until the master router comes back up and
takes over.

Vertically to rearrange the windows in the View Window Area in a way that makes them all
visible.
Windows in this area can be in one of several states:
NetAtlas Workgroup User’s Guide
229
Appendix A SNMPc Network Manager
• A Maximized window uses the entire area and hides any other windows behind it. If you
close a maximized window, the next top-most window will still be displayed in the
maximized state. You need to be careful when using maximized windows because it is
easy to lose track of how many windows you have open and there is an upper limit. Use
the Windows menu to see a list of windows. Click Windows and select either Tile
Horizontally or Tile Vertically to view all windows at the same time.
• An Overlapped window does not take up the entire area. One window will be completely
visible and other windows are partially hidden behind it. This is the most common
situation for the View Window area because it lets you view maps, tables and graphs at the
same time and quickly move between them. Click Windows and select Cascade.
• A Minimized window is displayed as a small title bar with window open/close buttons.
Windows are not typically minimized within the View Window Area because, as with the
maximized case, they can easily be lost behind other windows.
