Features and Applications
Part I
Features and Applications
This part acquaints you with the features and applications of the GS-3012.
I
Dimension GS-3012 Gigabit Ethernet Switch
Chapter 1
Getting to Know the GS-3012
This chapter describes the key features, benefits and applications of the GS-3012.
1.1 Introduction
The GS-3012 is a layer 2 stand-alone Gigabit Ethernet switch with 12 10/100/1000Mbps ports, four mini GBIC
slots for optical uplinking and one console port and RJ-45 port for local management.
With its built-in web configurator, managing and configuring the switch is easy. From cabinet management to portlevel control and monitoring, you can visually configure and manage your network via the web browser. Just click
your mouse instead of typing cryptic command strings. In addition, the switch can also be managed via Telnet, the
console port, or third-party SNMP management.
1.2 Features
The next two sections describe the hardware and firmware features of the GS-3012.
1.2.1
Hardware Features
Power
The GS-3012 DC model requires DC power supply input of -48 VDC to -60 VDC, 1.84A Max. The GS-3012 AC
model requires 100~240VAC/1.5A power.
12 10/100/1000 Mbps Gigabit Ports (with four paired with the mini GBIC ports)
Connect up to 12 computers or switches directly to the 10/100/1000Mbps auto-negotiating, automatic cable sensing
(auto-MDIX) Gigabit ports. All ports support:
IEEE 802.3/3u/3z/3ab standards
Back pressure flow control in half duplex mode
IEEE 802.3x flow control in full duplex mode
Four Mini GBIC Slots
These are slots for mini GBIC (Gigabit Interface Converter) transceiver. These allow the GS-3012 to connect to
another WAN switch or daisy-chain to other switches.
Console Port
Use the console port for local management of the switch.
Getting to Know the GS-3012
1-1
Dimension GS-3012 Gigabit Ethernet Switch
One Management Port
Use the RJ-45 management port for switch management only. The management port is out-of-band, meaning that it
does not carry switch traffic.
Fans
The fans cool the GS-3012 sufficiently to allow reliable operation of the switch in even poorly ventilated rooms or
basements.

Static MAC address filtering
Secure SHell communication protocol
Port Link Aggregation
The GS-3012 adheres to the 802.3ad standard for static and dynamic port link aggregation.
Bandwidth Control
The GS-3012 supports rate limiting in 1Mbps increments allowing you to create different service plans
The GS-3012 supports IGMP snooping enabling group multicast traffic to be only forwarded to ports that
are members of that group; thus allowing you to significantly reduce multicast traffic passing through your
switch.
Broadcast storm control
Quality of Service
Eight priority queues so you can ensure mission-critical data gets delivered on time.
Follows the IEEE 802.1p priority setting.
Advanced policy-based traffic shaping.
STP (Spanning Tree Protocol) / RSTP (Rapid STP)
(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.
Cluster Management
Cluster Management allows you to manage switches through one switch, called the cluster manager. The switches
must be directly connected and be in the same VLAN group so as to be able to communicate with one another.
1.3 Applications
This section shows a few examples of using the GS-3012 in various network environments.
1.3.1
Backbone Application
In this application, the switch is an ideal solution for small networks where rapid growth can be expected in the
near future.
The switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the
switch’s ports or connect other switches to the GS-3012.
Getting to Know the GS-3012
1-3
Dimension GS-3012 Gigabit Ethernet Switch
In this example, all computers connected directly or indirectly to the GS-3012 can share super high-speed
applications on the Gigabit server.
To expand the network, simply add more networking devices such as switches, routers, firewalls, print servers etc.
Figure 1-1 Backbone Application
1.3.2
Bridging Example
In this example application the switch is the ideal solution for different company departments to connect to the
corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users
that need high bandwidth can connect to high-speed department servers via the switch. You can provide a superfast uplink connection by installing the transceiver(s) in the mini GBIC slots on the GS-3012.
Moreover, the switch eases supervision and maintenance by allowing network managers to centralize multiple
servers at a single location.
1-4
Getting to Know the GS-3012
Dimension GS-3012 Gigabit Ethernet Switch
Figure 1-2 Bridging Application
Full-duplex mode operation only applies to point-to-point access (for example, when attaching
the switch to a workstation, server, or another switch). When connecting to hubs, use a standard
cascaded connection set at half-duplex operation.
1.3.3
High Performance Switched Workgroup Example
The switch is ideal for connecting two power workgroups that need high bandwidth. In the following example, use
trunking to connect these two power workgroups.
Switching to higher-speed LANs such as FDDI or ATM is not feasible for most people due to the expense of
replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance.
The GS-3012 can provide the same bandwidth as FDDI and ATM at much lower cost while still being able to use
existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely
communicate with each other.

1.3.4
IEEE 802.1Q VLAN Application Examples
This section shows a workgroup and a shared server example using 802.1Q tagged VLANs. For more information
on VLANs, see the Switch Setup section and the VLAN Setup chapter in this User’s Guide. A VLAN (Virtual Local
Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical
network belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly
talk to or hear from stations that are not in the same group(s) unless such traffic first goes through a router.
Tag-based VLAN Workgroup Example
Ports in the same VLAN group share the same broadcast domain thus increase network performance through
reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without
any re-cabling.

Figure 1-4 VLAN Workgroup Application
VLAN Shared Server Example
Shared resources such as a server can be used by all ports in the same VLAN as the server, as shown in the
following example. In this example, only ports that need access to the server need belong to VLAN 3 while they
can belong to other VLAN groups too.

Chapter 2
Hardware Installation
This chapter shows two switch installation scenarios.
2.1 Installation Scenarios
The switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop
installation and the brackets in a rack-mounted installation.
For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8
cm) at the back of the switch. This is especially important for enclosed rack installations.
2.1.1
Desktop Installation Procedure
Step 1. Make sure the switch is clean and dry.
Step 2. Set the switch on a smooth, level surface strong enough to support the weight of the switch and the
connected cables. Make sure there is a power outlet nearby.
Step 3. Make sure there is enough clearance around the switch to allow air circulation and the attachment of cables
and the power cord.
Step 4. Remove the adhesive backing from the rubber feet.
Step 5. Attach the rubber feet to each corner on the bottom of the switch. These rubber feet help protect the switch
from shock or vibration and ensure space between switches when stacking.
Figure 2-1 Attaching Rubber Feet
Do not block the ventilation holes. Leave space between switches when stacking.
2.1.2
Rack-Mounted Installation
The switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment.
Follow the steps below to mount your switch on a standard EIA rack using a rack-mounting kit.
Hardware Installation
2-1
Dimension GS-3012 Gigabit Ethernet Switch
Step 1. Align one bracket with the holes on one side of the switch and secure it with the bracket screws smaller
than the rack-mounting screws.
Step 2. Attach the other bracket in a similar fashion.
Figure 2-2 Attaching Mounting Brackets and Screws
Step 3. After attaching both mounting brackets, position the switch in the rack by lining up the holes in the
brackets with the appropriate holes on the rack. Secure the switch to the rack with the rack-mounting
screws.

Gigabit Ports
The GS-3012 has 10/100/1000Mbps auto-negotiating, auto-crossover Gigabit ports. The speed of the Gigabit ports
can be 10Mbps, 100Mbps or 1000Mbps and the duplex mode can be half duplex (for 10/100 Mbps) or full duplex.
When auto-negotiation is turned on, a Gigabit port on the GS-3012 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 GS-3012 determines the connection speed by detecting the signal on the cable and using
half duplex mode. When the GS-3012’s auto-negotiation is turned off, a Gigabit 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.
Four Gigabit ports are paired with the four mini GBIC slots. The switch uses up to one connection for each pair for
a total of four possible Gigabit connections (one from each of the four pairs). The mini GBIC ports have priority
over the Gigabit ports. This means that if a mini GBIC port and the corresponding Gigabit port are connected at the
same time, the Gigabit port will be disabled.
Default Ethernet Negotiation Settings
The factory default negotiation settings for the Gigabit ports on the GS-3012 are:
•
Speed: Auto
•
Duplex: Auto
•
Flow control: Off
•
Link Aggregation: Disabled
Auto-crossover
All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so you may use
either a straight-through Ethernet cable or crossover Ethernet cable for all Gigabit port connections. Auto-crossover
ports automatically sense whether they need to function as crossover or straight ports, so crossover cables can
connect both computers and switches/hubs.
3.2.3
Mini GBIC Slots
These are slots for mini GBIC (Gigabit Interface Converter) transceiver. A transceiver is a single unit that houses a
transmitter and a receiver. The GS-3012 does not come with transceivers. You must use transceivers that comply
with the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s
INF-8074i specification Rev 1.0 for details.
You can change transceivers while the switch is operating. You can use different transceivers to connect to Ethernet
switches with different types of fiber-optic connectors.
To avoid possible eye injury, do not look into an operating fiber-optic module’s connectors.

Management Port
The MGNT (management) port is used for local management. The port is not used for network data transmission
meaning that it is out-of-band. Connect directly to this port using an Ethernet cable. You can configure the switch
via Telnet or the web configurator.
The default IP address of the management port is 192.168.0.1 with a subnet mask of 255.255.255.0.

3.3 Rear Panel
The following figure shows the rear panel of the GS-3012. The rear panel contains the ventilation holes, a
connector for external backup power supply (BPS) and the power receptacle.
Figure 3-6 GS-3012 Rear Panel: AC Model
Figure 3-7 GS-3012 Rear Panel: DC Model
3.3.1
Power Connector
Make sure you are using the correct power source as shown on the panel.
To connect the power to the GS-3012 AC unit, insert the female end of power cord to the power receptacle on the
rear panel. Connect the other end of the supplied power cord to a 100~240VAC/1.5A power outlet. Make sure that
no objects obstruct the airflow of the fans (located on the side of the unit).
The GS-3012 DC unit requires DC power supply input of –48 VDC to -60 VDC, 1.84A Max. To connect the power
to the unit, insert the one end of the supplied power cord to the power receptacle on the rear panel and the other end
to a power outlet.
3.3.2
External Backup Power Supply Connector
The GS-3012 supports external backup power supply. Connect to the backup power supply.
The backup power supply constantly monitors the status of the internal power supply. The backup power supply
automatically provides power into the switch in the event of a power failure. Once the GS-3012 receives power
from the backup power supply, it will not automatically switch back to using the internal power supply even when
the power is resumed.

3.5 Configuring the GS-3012
You may use the embedded web configurator or command line interface to configure the GS-3012. If you’re using
the web configurator, you need Internet Explorer 5.5 and later or Netscape Navigator 6 and later.
You can access the command line interface using a terminal emulation program on a computer connected to the
switch console port (see Section 3.2.1) or access the switch using Telnet.
You can use the “config save” command to save 802.1Q, STP, Cluster and IP configuration
changes to non-volatile memory (Flash). These changes are effective after you restart the switch.
However you cannot use “config save” for all other line command configurations. These are
saved in volatile memory (DRAM), so are not effective after you restart the switch.
The next part of this guide discusses configuring the GS-3012 using the web configurator.

4.4 Switch Lockout
You are locked out from managing the switch if another administrator is currently logged in. You must wait until
he/she has logged out before you can log in.
Moreover, you could lock yourself (and all others) out from the switch by:
1. Deleting the management VLAN (default is VLAN 1).
2. Deleting all port-based VLANs with the CPU port as a member. The “CPU port” is the management port of
the switch.
3. Filtering all traffic to the CPU port.
4. Disabling all ports.
5. Assigning minimum bandwidth to the CPU port. If you limit bandwidth to the CPU port, you may find that
the switch performs sluggishly or not at all.
Be careful not to lock yourself and others out of the switch.
4.5 Resetting the Switch
If you lock yourself (and others) from the switch or forget the GS-3012 password, you will need to reload the
factory-default configuration file.
Uploading the factory-default configuration file replaces the current configuration file with the factory-default
configuration file. This means that you will lose all previous configurations and the speed of the console port will

timeservers support all protocols, so you may have to use trial and error to find a protocol that
works. The main differences between them are the time format.
Daytime (RFC 867) format is day/month/year/time zone of the server.
Time (RFC-868) format displays a 4-byte integer giving the total number of seconds since
1970/1/1 at 0:0:0.
NTP (RFC-1305) is similar to Time (RFC-868).

6.4 Introduction to VLANs
Basic Setting
6-5
Dimension GS-3012 Gigabit Ethernet Switch
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.
See the VLAN chapter for information on port-based and 802.1Q tagged VLANs.
6.5 IGMP Snooping
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a Multicast
group - it is not used to carry user data. Refer to RFC 2236 for information IGMP version 2 and RFC 1112 for
IGMP version 1.
A layer-2 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.
Without IGMP snooping, multicast traffic is treated in the same manner as broadcast traffic, that is, it is forwarded
to all ports. With IGMP snooping, group multicast traffic is only forwarded 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.

Priority Queue Assignment
IEEE 802.1p defines up to eight 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
the next two fields to configure the priority level-to-physical queue mapping.
The switch has eight physical queues that you can map to the eight priority levels. 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.
See also Queuing Method and 802.1p Priority in Port Setup for related information.
Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d standard (which
incorporates the 802.1p).
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.

Selecting Auto (auto-negotiation) makes one Gigabit 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, a Gigabit 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, a Gigabit 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
DESCRIPTION
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 IEEE802.3x flow control in full duplex mode and backpressure flow control in half
duplex mode.
IEEE802.3x 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 this option to enable flow control.

VLAN
The type of screen you see here depends on the VLAN Type you selected in the Switch Setup screen.
This chapter shows you how to configure 802.1Q tagged and port-based VLANs. See the General,
Switch and IP Setup chapter for more information.
7.1 Introduction to IEEE 802.1Q Tagged VLAN
Tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame
across bridges - they are not confined to the switch on which they were created. The VLANs can be created
statically by hand or dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN and
provides the information that switches need to process the frame across the network. A tagged frame is four bytes
longer than an untagged frame and contains two bytes of TPID (Tag Protocol Identifier, residing within the
type/length field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts after the source
address field of the Ethernet frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a frame
received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to an untagged port.
The remaining twelve bits define the VLAN ID, giving a possible maximum number of 4,096 (212) VLANs. Note
that user priority and VLAN ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is
called a priority frame, meaning that only the priority level is significant and the default VID of the ingress port is
given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value
4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094

Forwarding Tagged and Untagged Frames
Each port on the switch is capable of passing tagged or untagged frames. To forward a frame from an 802.1Q
VLAN-aware switch to an 802.1Q VLAN-unaware switch, the switch first decides where to forward the frame
and then strips off the VLAN tag. To forward a frame from an 802.1Q VLAN-unaware switch to an 802.1Q
VLAN-aware switch, the switch first decides where to forward the frame, and then inserts a VLAN tag reflecting
the ingress port's default VID. The default PVID is VLAN 1 for all ports, but this can be changed.
7.1.2
Automatic VLAN Registration
GARP and GVRP are the protocols used to automatically register VLAN membership across switches.
VLAN
7-1
Dimension GS-3012 Gigabit Ethernet Switch
GARP
GARP (Generic Attribute Registration Protocol) allows network switches to register and de-register attribute
values with other GARP participants within a bridged LAN. GARP is a protocol that provides a generic
mechanism for protocols that serve a more specific application, for example, GVRP.
GARP Timers
Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP.
Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP
timers set declaration timeout values.
GVRP
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. Enable this function to permit VLANs groups beyond the
local switch.

Port VLAN Trunking
Enable VLAN Trunking on a port to allow frames belonging to unknown VLAN groups to pass through that
port. This is useful if you want to set up VLAN groups on end devices without having to configure the same
VLAN groups on intermediary devices.
Refer to the following figure. Suppose you want to create VLAN groups 1 and 2 (V1 and V2) on devices A and B.
Without VLAN Trunking, you must configure VLAN groups 1 and 2 on all intermediary switches C, D and E;
otherwise they will drop frames with unknown VLAN group tags. However, with VLAN Trunking enabled on a
port(s) in each intermediary switch you only need to create VLAN groups in the end devices (A and B). C, D and
E automatically allow frames with VLAN group tags 1 and 2 (VLAN groups that are unknown to those switches)
to pass through their VLAN trunking port(s).

7.3 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.
Port-based VLANs are specific only to the switch on which they were created.
The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN with all Gigabit
ports.

All connected means all ports can communicate with each other, that is, there are no virtual
LANs. All incoming and outgoing ports are selected (Figure 7-8). 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 (Figure 7-9). This option is the most limiting but also the most secure.
After you make your selection, click Apply (top right of screen) 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.
Incoming
VLAN
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 Gigabit ports. If it does not form a VLAN with a particular
port then the switch cannot be managed from that port.

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 Gigabit ports. If it does not form a VLAN with a particular port then the switch
cannot be managed from that port.

Static MAC Forward Setup
Use these screens to configure static MAC address forwarding.
8.1 Introduction to Static MAC Forward Setup
A static MAC address entry is an address that has been manually entered in the MAC address learning table.
Static MAC addresses do not age out. When you set up static MAC address rules, you are setting static MAC
addresses for a port. Devices that match static MAC address rules on a port can only receive traffic on that port
and cannot receive traffic on other ports. This may reduce unicast flooding.

Spanning Tree Protocol
This chapter introduces the Spanning Tree Protocol (STP).
10.1 Introduction to Spanning Tree Protocol (STP)
STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows a
switch to interact with other STP-compliant switches in your network to ensure that only one route exists between
any two stations on the network.
10.1.1
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.
Table 10-1 STP Path Costs

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.
10.1.2
How STP Works
After a bridge determines the lowest cost-spanning tree with STP, it enables the root port and the ports that are the
designated ports for connected LANs, and disables all other ports that participate in STP. Network packets are
therefore only forwarded between enabled ports, eliminating any possible network loops.
STP-aware switches exchange Bridge Protocol Data Units (BPDUs) periodically. When the bridged LAN
topology changes, a new spanning tree is constructed.
Spanning Tree Protocol
10-1
Dimension GS-3012 Gigabit Ethernet Switch
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 (Max
Age), the bridge assumes that the link to the root bridge is down. This bridge then initiates negotiations with other
bridges to reconfigure the network to re-establish a valid network topology.
10.1.3
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.
Table 10-2 STP Port States

LABEL
DESCRIPTION
Active
Select this check box to activate STP.
Bridge Priority
Bridge priority is used in determining the root switch, root port and designated port. The switch with
the highest priority (lowest numeric value) becomes the STP root switch. If all switches have the
same priority, the switch with the lowest MAC address will then become the root switch. The
allowed range is 0 to 61440.
The lower the numeric value you assign, the higher the priority for this bridge.
Bridge Priority determines the root bridge, which in turn determines Hello Time, Max Age and
Forwarding Delay.
Hello Time
This is the time interval in seconds between BPDU (Bridge Protocol Data Units) configuration
message generations by the root switch. The allowed range is 1 to 10 seconds.
Max Age
This is the maximum time (in seconds) a switch can wait without receiving a BPDU before
attempting to reconfigure. All switch 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
switch ports attached to the network. The allowed range is 6 to 40 seconds.
Forwarding
Delay
This is the maximum time (in seconds) a switch will wait before changing states. This delay is
required because every switch 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.
As a general rule:
2 * (Forward Delay - 1) >= Max Age >= 2 * (Hello Time + 1)
Port
This field displays the port number.
Active
Select this check box to activate STP on this port.
Priority
Configure the priority for each port here.
Priority decides which port should be disabled when more than one port forms a loop in a switch.
Ports with a higher priority numeric value are disabled first. The allowed range is between 0 and
255 and default value is 128.
Path Cost
Path cost is the cost of transmitting a frame on to a LAN through that port. It is assigned according
to the speed of the bridge. The slower the media, the higher the cost - see Table 10-1 for more
information.

Link Aggregation
This chapter shows you how to logically aggregate physical links to form one logical, higher-bandwidth
link.
14.1 Introduction to 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.
14.1.1
Dynamic Link Aggregation
The GS-3012 adheres to the 802.3ad standard for static and dynamic (LACP) port trunking.
The GS-3012 supports the link aggregation IEEE802.3ad 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.

Port Authentication
This chapter describes the 802.1x authentication method and RADIUS server connection setup.
15.1 Introduction to Authentication
IEEE 802.1x is an extended authentication protocol2 that allows support of RADIUS (Remote Authentication Dial
In User Service, RFC 2138, 2139) for centralized user profile management on a network RADIUS server.
15.1.1
RADIUS
RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used to authenticate
users by means of an external server instead of (or in addition to) an internal device user database that is limited to
the memory capacity of the device. In essence, RADIUS authentication allows you to validate an unlimited
number of users from a central location.
Figure 15-1 RADIUS Server
15.2 Configuring Port Authentication
To enable port authentication, first activate IEEE802.1x security (both on the GS-3012 and the port(s)) then

At the time of writing, Windows XP of the Microsoft operating systems supports 802.1x. See the Microsoft web site for
information on other Windows operating system support. For other operating systems, see its documentation. If your
operating system does not support 802.1x, then you may need to install 802.1x client software.

Port security allows only packets with dynamically learned MAC addresses and/or configured static MAC
addresses to pass through a port on the switch. The switch can learn up to 16K MAC addresses in total with no
limit on individual ports other than the sum cannot exceed 16K.
For maximum port security, enable this feature, disable MAC address learning and configure static MAC
address(es) for a port. It is not recommended you disable Port Security together with MAC address learning as
this will result in many broadcasts.

17.3 About 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
GS-3012 through the network via SNMP version one (SNMPv1) and/or SNMP version 2c. The next figure
illustrates an SNMP management operation. SNMP is only available if TCP/IP is configured.
Figure 17-3 SNMP Management Model
An SNMP managed network consists of two main components: agents and a manager.
An agent is a management software module that resides in a managed switch (the GS-3012). 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 17-2 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
SNMPv1, 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.
17.3.1
Supported MIBs
MIBs let administrators collect statistics and monitor status and performance.
The GS-3012 supports the following MIBs:
SNMP MIB II (RFC 1213)

17.4 SSH Overview
Access Control
17-5
Dimension GS-3012 Gigabit Ethernet Switch
Unlike Telnet or FTP, which transmit data in clear text, SSH (Secure Shell) is a secure communication protocol that
combines authentication and data encryption to provide secure encrypted communication between two hosts over
an unsecured network.
Figure 17-6 SSH Communication Example
17.5 How SSH works
The following table summarizes how a secure connection is established between two remote hosts.
1. Host Identification
The SSH client sends a connection request to the SSH
server. The server identifies itself with a host key. The client
encrypts a randomly generated session key with the host key
and server key and sends the result back to the server.
The client automatically saves any new server public keys. In
subsequent connections, the server public key is checked
against the saved version on the client computer.
2. Encryption Method
Once the identification is verified, both the client and server
must agree on the type of encryption method to use.
3. Authentication and Data Transmission
After the identification is verified and data encryption
activated, a secure tunnel is established between the client
and the server. The client then sends its authentication
information (user name and password) to the server to log in
to the server.
Figure 17-7How SSH Works
17.6 SSH Implementation
Your switch supports SSH versions 1 and 2 using RSA and DSA authentication and five encryption methods (AES,
3DES, RC4, Blowfish and CAST). The SSH server is implemented on the switch for remote SMT management and
file transfer on port 22 (by default). Up to four SSH connections are allowed at a time.
17.6.1
Requirements for Using SSH
You must install an SSH client program on a client computer (Windows or Linux operating system) that is used to
connect to the switch over SSH.

17.7 Introduction to HTTPS
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web protocol that
encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-level protocol that enables secure
transactions of data by ensuring confidentiality (an unauthorized party cannot read the transferred data),
authentication (one party can identify the other party) and data integrity (you know if data has been changed).
It relies upon certificates, public keys, and private keys.
HTTPS on the switch is used so that you may securely access the switch using the web configurator. The SSL
protocol specifies that the SSL server must always authenticate itself to the SSL client (the computer which
requests the HTTPS connection with the switch), whereas the SSL client only should authenticate itself when the
SSL server requires it to do so.
Please refer to the following figure.
Step 1. HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the switch’s
WS (web server).
Step 2. HTTP connection requests from a web browser go to port 80 (by default) on the switch’s WS.
Figure 17-8 HTTPS Implementation
If you disable HTTP in the Service Access Control screen, then the switch blocks all HTTP
connection attempts.
17.7.1
HTTPS Example
If you haven’t changed the default HTTPS port on the switch, then in your browser enter “https:// switch IP
Address/” as the web site address where “switch IP Address” is the IP address or domain name of the switch you
wish to access.
The HTTPS proxy server listens on port 443 by default. If you change the HTTPS proxy server port to a different
number on the switch, for example 8443, then you must notify people who need to access the switch web
configurator to use “https:// switch IP Address:8443” as the URL.

Queuing Method
This chapter introduces SPQ and WRR.
18.1 Introduction to Queuing
Queuing is used to help solve performance degradation when there is network congestion. Use the Queuing
Method screen to configure queuing algorithms for outgoing traffic. See also Priority Queue Assignment in
Switch Setup and 802.1p Priority in Port Setup for related information.
Queuing algorithms allow switches to maintain separate queues for packets from each individual source or flow and
prevent a source from monopolizing the bandwidth.
The switch has eight physical queues, Q0 to Q7. Q7 has the highest priority and Q0 has the lowest.

Strict Priority Queuing (SPQ)
Strict Priority Queuing (SPQ) services queues based on priority only. As traffic comes into the switch, traffic on the
highest priority queue, Q7 is transmitted first. When that queue empties, traffic on the next highest-priority queue,
Q6 is transmitted until Q6 empties, and then traffic is transmitted on Q5 and so on. If higher priority queues never
empty, then traffic on lower priority queues never gets sent. SPQ does not automatically adapt to changing network
requirements.
18.1.2
Weighted Round Robin Scheduling (WRR)
Round Robin Scheduling services queues on a rotating basis and is activated only when a port has more traffic than
it can handle. A queue is given an amount of bandwidth irrespective of the incoming traffic on that port. This queue
then moves to the back of the list. The next queue is given an equal amount of bandwidth, and then moves to the
Queuing Method
18-1
Dimension GS-3012 Gigabit Ethernet Switch
end of the list; and so on, depending on the number of queues being used. This works in a looping fashion until a
queue is empty.
Weighted Round Robin Scheduling (WRR) uses the same algorithm as round robin scheduling, but services queues
based on their priority and queue weight (the number you configure in the Weight field – see Figure 18-1) rather
than a fixed amount of bandwidth. WRR is activated only when a port has more traffic than it can handle. Queues
with larger weights get more service than queues with smaller weights. This queuing mechanism is highly efficient
in that it divides any available bandwidth across the different traffic queues and returns to queues that have not yet
emptied.

configure in the queue Weight field). Queues with larger weights get more service than queues
with smaller weights.

Classifier
This chapter introduces and shows you how to configure the packet classifier on the GS-3012.
19.1 About the Classifier and QoS
Quality of Service (QoS) refers to both a network’s ability to deliver data with minimum delay, and the networking
methods used to control the use of bandwidth. Without QoS, all traffic data is equally likely to be dropped when the
network is congested. This can cause a reduction in network performance and make the network inadequate for
time-critical application such as video-on-demand.
A classifier groups traffic into data flows according to specific criteria such as the source address, destination
address, source port number, destination port number or incoming port number. For example, you can configure a
classifier to select traffic from the same protocol port (such as Telnet) to form a flow.
Configure QoS on the switch to group and prioritize application traffic and fine-tune network performance. Setting
up QoS involves two separate steps:
1. Configure classifiers to sort traffic into different flows.
2. Configure policy rules to define actions to be performed for a classified traffic flow (refer to Chapter 20 to
configure policy rules).
19.2 Configuring the Classifier
Use the Classifier screen to define the classifiers. After you define the classifier, you can specify actions (or policy)
to act upon the traffic that match the rules. To configure policy rules, refer to Chapter 20 .

Policy Rule
This chapter shows you how to configure policy rules.
20.1 About Policy Rules
A classifier distinguishes traffic into flows based on the configured criteria (refer to Chapter 19 for more
information). A policy rule ensures that a traffic flow gets the requested treatment in the network.
20.1.1
DiffServ
DiffServ (Differentiated Services) is a class of service (CoS) model that marks packets so that they receive specific
per-hop 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.
20.1.2
DSCP and Per-Hop Behavior
DiffServ defines a new DS (Differentiated Services) field to replace the Type of Service (TOS) field in the IP
header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define up to 64 service levels.
The following figure illustrates the DS field.
DSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ compliant, ToSenabled network device will not conflict with the DSCP mapping.
DSCP (6 bits)
Unused (2 bits)
The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the
DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different kinds of
forwarding. Resources can then be allocated according to the DSCP values and the configured policies.
20.2 Configuring Policy Rules

DHCP Relay
This chapter describes the DHCP relay and shows you how to configure the DHCP Relay screen.
21.1 Overview
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain
TCP/IP configuration at start-up from a DHCP server. You can configure the switch to relay client TCP/IP
configuration requests to a DHCP server and the server’s responses back to the clients.
21.1.1
DHCP “Relay Agent Information Option”
The switch can add information to client TCP/IP configuration 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 TCP/IP configuration requests that it relays to the DHCP server. Please refer to RFC 3046 for
more details.
21.1.2
DHCP Relay Agent Circuit ID Sub-option Format
The DHCP relay agent information feature adds an Agent Information field to the option 82 field of the DHCP
headers of client TCP/IP configuration request frames that the switch relays to a DHCP server. The Agent
Information field that the switch adds contains an “Agent Circuit-ID sub-option” that includes the port number,
VLAN ID and optional information about the port where the TCP/IP configuration request was received.
21.2 DHCP Relay Configuration
To configure DHCP relay information and specify the DHCP server(s), click Advanced Application and DHCP
Relay to display the screen as shown next.

Dimension GS-3012 Gigabit Ethernet Switch
23.7.1
Filename Conventions
The configuration file (often called the romfile or rom-0) contains the factory default settings in the screens such as
password, switch setup, IP Setup, etc. Once you have customized the switch's settings,
they can be saved back to your computer under a filename of your choosing.
ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the system firmware and
has a “bin” filename extension.
Table 23-1 Filename Conventions
FILE TYPE

EXTERNAL
NAME
DESCRIPTION
This is the configuration filename on the switch. Uploading the
config file replaces the specified configuration file system,
including your switch configurations, system-related data
(including the default password), the error log and the trace log.
*.bin
This is the generic name for the ZyNOS firmware on the switch.
Example FTP Commands
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file " firmware.bin" to the switch .
ftp> get config config.cfg
This is a sample FTP session saving the current configuration to a file called “config.cfg” on your computer.
If your (T)FTP client does not allow you to have a destination filename different than the source, you will need to
rename them as the switch only recognizes “config” and “ras”. Be sure you keep unaltered copies of both files for
later use.
Be sure to upload the correct model firmware as uploading the wrong model firmware may
damage your device.
23.7.2
FTP Command Line Procedure
Step 1. Launch the FTP client on your computer.
Step 2. Enter “open”, followed by a space and the IP address of your switch.
Step 3. Press [ENTER] when prompted for a username.
Step 4. Enter your password as requested (the default is “1234”).
Step 5. Enter “bin” to set transfer mode to binary.
Step 6. Use “put” to transfer files from the computer to the switch, for example, “put firmware.bin ras” transfers
the firmware on your computer (firmware.bin) to the switch and renames it “ras”. Similarly, “put
config.cfg config” transfers the configuration file on your computer (config.cfg) to the switch and
23-4
Maintenance
Dimension GS-3012 Gigabit Ethernet Switch
renames it “config”. Likewise “get config config.cfg” transfers the configuration file on the switch to your
computer and renames it “config.cfg”. See earlier in this chapter for more information on filename
conventions.
Step 7. Enter “quit” to exit the ftp prompt.

MAC Table
This chapter introduces MAC Table.
26.1 Introduction to MAC Table
The MAC table shows how frames are forwarded or filtered across the switch’s ports. It shows what device MAC
address, belonging to what VLAN group (if any) is forwarded to which port(s) and whether the MAC address is
dynamic (learned by the switch) or static (manually entered in Static MAC Forwarding).
The switch uses the Filtering Database to determine how to forward frames. See the following figure.
1. The switch examines a received frame and learns the port on which this source MAC address came.
2. The switch checks to see if the frame's destination MAC address matches a source MAC address already
learned in the Filtering Database.
If the switch has already learned the port for this MAC address, then it forwards the frame to that port.
If the switch has not already learned the port for this MAC address, then the frame is flooded to all
ports. Too much port flooding leads to network congestion.
If the switch has already learned the port for this MAC address, but the destination port is the same as
the port it came in on, then it filters the frame.

Chapter 27
ARP Table
This chapter introduces ARP Table.
27.1 Introduction to ARP Table
Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a
physical machine address, also known as a Media Access Control or MAC address, on the local area network.
An IP (version 4) address is 32 bits long. In an Ethernet LAN, MAC addresses are 48 bits long. The ARP Table
maintains an association between each MAC address and its corresponding IP address.
27.1.1
How ARP Works
When an incoming packet destined for a host device on a local area network arrives at the switch, the switch's ARP
program looks in the ARP Table and, if it finds the address, sends it to the device.
If no entry is found for the IP address, ARP broadcasts the request to all the devices on the LAN. The switch fills in
its own MAC and IP address in the sender address fields, and puts the known IP address of the target in the target
IP address field. In addition, the switch puts all ones in the target MAC field (FF.FF.FF.FF.FF.FF is the Ethernet
broadcast address). The replying device (which is either the IP address of the device being sought or the router that
knows the way) replaces the broadcast address with the target's MAC address, swaps the sender and target pairs,
and unicasts the answer directly back to the requesting machine. ARP updates the ARP Table for future reference
and then sends the packet to the MAC address that replied.

Dimension GS-3012 Gigabit Ethernet Switch
Chapter 28
Introducing the Commands
This chapter introduces the commands and gives a summary of commands available.
28.1 Overview
In addition to the web configurator, you can use line commands to configure the switch. Use line commands for
advanced switch diagnosis and troubleshooting. If you have problems with your switch, customer support may
request that you issue some of these commands to assist them in troubleshooting.
28.1.1
Switch Configuration File
When you configure the switch using either the CLI or web configurator, the settings are saved as a series of
commands in a configuration file on the switch. You can perform the following with a configuration file:
Back up switch configuration once the switch is set up to work in your network.
Restore switch configuration.
Use the same configuration file to set all switches (of the same model) in your network to the same settings.
You may also edit a configuration file using a text editor.
Make sure you use valid commands. The switch rejects configuration files with invalid or
incomplete commands.
28.2 Accessing the CLI
You can use a direct console connection or Telnet to access the CLI on the switch.
The switch automatically logs you out of the management interface after five minutes of
inactivity. If this happens to you, simply log back in again.
28.2.1
Access Priority
You can only access the CLI with the administrator account (the default username is admin and password
is 1234).
By default, only one concurrent access to the CLI is allowed via either the console port or Telnet. Console
port access has higher priority.
Use the configure multi-login command in the configuration mode to allow multiple concurrent
logins. However, no more than five concurrent login sessions are allowed.
Introduction to CLI

28.4 Command Syntax Conventions
The rules of the commands are listed next.
The command keywords are in courier new font.
The required fields in a command are enclosed in angle brackets <>, for instance, ping <ip> means that
you must specify an IP number for this command.
The optional fields in a command are enclosed in square brackets [], for instance,
configure snmp-server [contact <system contact>] [location <system location>]
means that the contact and location fields are optional.
“Command” refers to a command used in the command line interface (CI command).
The | symbol means “or”.
The entry <cr> in the command lines refers to carriage return. Press [ENTER] or carriage return after a
command to execute the command.
Use the up (y) or down (z) arrow key to scroll through the command history list.
The CLI does not accept partial or incomplete commands. You may enter a unique part of a command and
press [TAB] to have the switch automatically display the full command. For example, if you enter
“config” and press [TAB], the full command of “configuration” automatically displays.
Each interface refers to a switch Ethernet port. Commands configured after the interface command
correspond to those ports.
Type multiple ports or port ranges separated by a comma. Ranges of port numbers are typed separated by a
dash.
28.5 Getting Help

28.6 Command Modes
There are three CLI command modes: User, Enable and Configure.
When you first log into the CLI, the initial command mode is the User mode. The User mode commands are a
subset of the Enable mode commands. The User mode command prompt ends with an angle bracket (>).
To enter Enable (or privileged) mode, type “enable” and enter a password when prompted (the default is 1234).
When you enter the Enable mode, the command prompt changes to the pound sign (#).
To enter the configuration mode, type “configuration” or “config”. The Configure mode command prompt
consists of the word “config” and the pound sign (#). There are two sub configuration modes: VLAN and
interface. To enter config-vlan mode, type “vlan” followed by a number (between 1 to 4094). For example, vlan
10. To enter config-interface mode, enter interface followed by a port number. For example, interface 10.
Enter “exit” or “logout” to quit from the current mode or log out from the CLI.
28.7 Using Command History
The switch keeps a list of up to 256 commands(s) you have entered for the current CLI session. You can use any
commands in the history again by pressing the up (y) or down (z) arrow key to scroll through the previously used
commands and press [ENTER]. Use the history command to display the list of commands.

28.8 Saving Your Configuration
After you set the switch settings with the configuration commands, use the write memory command to save the
changes permanently to the configuration file that you are using.
GS-3012# write memory
Figure 28-8 CLI: write memory
The write memory command is not available in User mode.
You must save your changes after each CLI session. All unsaved configuration changes are lost
once you restart the switch.

Figure 29-11 CLI: Restore Configuration Example
29.6.3
Using a Different Configuration File
You can store up to two configuration files on the switch. Only one configuration file is used at a time. By default
the switch uses the first configuration file (with an index number of 1). You can set the switch to use a different
configuration file. There are two ways in which you can set the switch to use a different configuration file: restart
the switch (cold reboot) and restart the system (warm reboot).
Use the boot config command to restart the switch and use a different configuration file (if specified). The
following example reboots the switch to use the second configuration file.
29-6
Command Examples
Dimension GS-3012 Gigabit Ethernet Switch
GS-3012# boot config 2
Figure 29-12 CLI: boot config Command Example
Use the reload config command to restart the system and use a different configuration file (if specified). The
following example restarts the system to use the second configuration file.
GS-3012# reload config 2
Figure 29-13 CLI: reload config Command Example
When you use the write memory command without specifying a configuration file index number,
the switch saves the changes to the configuration file the switch is currently using.
29.6.4
Resetting to the Factory Default
Follow the steps below to reset the switch back to the factory defaults.
1. Enter erase running config to reset the current running configuration.
2. Enter write memory to save the changes to the current configuration file. If you want to reset the
second configuration file, use the write memory command again with the specified index number.
The following example resets both configuration files to the factory default settings.
GS-3012# erase running-config
GS-3012# write memory
GS-3012# write memory 2

IEEE 802.1Q Tagged VLAN Commands
This chapter describes the IEEE 802.1Q Tagged VLAN and associated commands.
30.1 IEEE 802.1Q Tagged VLAN Overview
See the VLAN chapter for more information on VLANs. There are two kinds of tagging:
1. Explicit Tagging
A VLAN identifier is added to the frame header that identifies the source VLAN.
2.
Implicit Tagging
The MAC (Media Access Control) number, the port or other information is used to identify the source of a VLAN
frame.
The IEEE 802.1Q Tagged VLAN uses both explicit and implicit tagging.
Whether to tag an outgoing frame depends on the setting of the egress port on a per-LAN, per-port basis (recall that
a port can belong to multiple VLANs). If the tagging on the egress port is enabled for the VID of a frame, then the
frame is transmitted as a tagged frame; otherwise, it is transmitted as an untagged frame.
30.2 VLAN Databases
A VLAN database stores and organizes VLAN registration information useful for switching frames to and from a
switch. A VLAN database consists of a static entries (Static VLAN or SVLAN table) and dynamic entries
(Dynamic VLAN or DVLAN table).
30.2.1
Static Entries (SVLAN Table)
Static entry registration information is added, modified and removed by administrators only.
30.2.2
Dynamic Entries (DVLAN Table)
Dynamic entries are learned by the switch and cannot be created or updated by administrators. The switch learns
this information by observing what port, source address and VLAN ID (or VID) is associated with a frame. Entries
are added and deleted using GARP VLAN Registration Protocol (GVRP), where GARP is the Generic Attribute
Registration Protocol.
30.3 Configuring Tagged VLAN
IEEE 802.1Q Tagged VLAN Commands
30-1
Dimension GS-3012 Gigabit Ethernet Switch
The following procedure shows you how to configure tagged VLAN.
3. Use the IEEE 802.1Q tagged VLAN commands to configure tagged VLAN for the switch.
•
Use the vlan <vlan-id> command to configure or create a VLAN on the switch. The switch
automatically enters the config-vlan mode.
•
Use the exit command when you are finished configuring the VLAN.
•
Use the interface <port-list> command to enter the config-interface mode to set the VLAN settings
on a port, then use the pvid <vlan-id> command to set the VLAN ID you created for the port-list to
that specific port in the PVID table.
•
Use the inactive command to deactivate the VLAN(s).
Example:
GS-3012 (config)# vlan 2000
GS-3012 (config-vlan)# name up1
GS-3012 (config-vlan)# fixed 10-12
GS-3012 (config-vlan)# no untagged 10-12
GS-3012 (config-vlan)# exit
GS-3012 (config)# interface 10-12
GS-3012 (config-interface)# pvid 2000
GS-3012 (config-interface)# exit
Figure 30-1 Tagged VLAN Configuration and Activation Example
4. Configure your management VLAN.
•
Use the vlan <vlan-id> command to create a VLAN (VID 3 in this example) for managing the switch,
and the switch will activate the new management VLAN.
•
Use the inactive command to disable the new management VLAN.
Example:
GS-3012 (config)# vlan 3
GS-3012 (config-vlan)# inactive

GARP Status
IEEE 802.1Q Tagged VLAN Commands
Dimension GS-3012 Gigabit Ethernet Switch
Syntax:
show garp
This command shows the switch’s GARP timer settings, including the join, leave and leave all timers.
An example is shown next.
GS-3012 # show garp
GARP Timer
-----------------------Join Timer = 200
Leave Timer = 600
Leave All Timer = 10000
GS-3012#
Figure 30-3 GARP STATUS Command Example
30.4.2
GARP Timer
Syntax:
garp join <msec> leave <msec> leaveall <msec>
where
join <msec>
=
This sets the duration of the Join Period timer for GVRP in milliseconds.
Each port has a Join Period timer. The allowed Join Time range is
between 100 and 32767 milliseconds; the default is 200 milliseconds.
leave <msec>
=
This sets the duration of the Leave Period timer for GVRP in
milliseconds. Each port has a single Leave Period timer. Leave Time
must be two times larger than Join Timer; the default is 600 milliseconds.
leaveall <msec>
=
This sets the duration of the Leave All Period timer for GVRP in
milliseconds. Each port has a single Leave All Period timer. Leave All
Timer must be larger than Leave Timer; the default is 10000
milliseconds.
This command sets the switch’s GARP timer settings, including the join, leave and leave all timers.
Switches join VLANs by making a declaration. A declaration is made by issuing a Join message using GARP.
Declarations are withdrawn by issuing a Leave message. A Leave All message terminates all registrations. GARP
timers set declaration timeout values.
The following example sets the Join Timer to 300 milliseconds, the Leave Timer to 800 milliseconds and the Leave
All Timer to 11000 milliseconds.
GS-3012 (config)# garp join 300 leave 800 leaveall 11000

Syntax:
vlan <vlan-id>
fixed <port-list>
forbidden <port-list>
name <name-str>
normal <port-list>
untagged <port-list>
no fixed <port-list>
no forbidden <port-list>
no untagged <port-list>
IEEE 802.1Q Tagged VLAN Commands
30-5
Dimension GS-3012 Gigabit Ethernet Switch
where
<vlan-id>
=
The VLAN ID [1 – 4094].
<name-str>
=
A name to identify the SVLAN entry.
<port-list> =
This is the switch port list.
Enter fixed to register the <port-list> to the static VLAN table with <vlan-id>.
Enter normal to confirm registration of the <port-list> to the static VLAN table with <vlan-id>.
Enter forbidden to block a <port-list> from joining the static VLAN table with <vlan-id>.
Enter no fixed or no forbidden to change <port-list> to normal status.
Enter untagged to send outgoing frames without a tag.
Enter no untagged to tag outgoing frames.
Modify a Static VLAN Table Example
The following example configures ports 1 to 5 as fixed and untagged ports in VLAN 2000.
GS-3012 (config)# vlan 2000
GS-3012 (config-vlan)# fixed 1-5
GS-3012 (config-vlan)# untagged 1-5
Figure 30-8 Modifying Static VLAN Example
Forwarding Process Example
Tagged Frames
1. First the switch checks the VLAN ID (VID) of tagged frames or assigns temporary VIDs to untagged
frames.
2. The switch then checks the VID in a frame’s tag against the SVLAN table.
3. The switch notes what the SVLAN table says (that is, the SVLAN tells the switch whether or not to
forward a frame and if the forwarded frames should have tags).
4. Then the switch applies the port filter to finish the forwarding decision. This means that frames may be
dropped even if the SVLAN says to forward them. Frames might also be dropped if they are sent to a CPE
(customer premises equipment) DSL device that does not accept tagged frames.
Untagged Frames
1. An untagged frame comes in from the LAN.
2. The switch checks the PVID table and assigns a temporary VID of 1.
3. The switch ignores the port from which the frame came, because the switch does not send a frame to the
port from which it came. The switch also does not forward frames to “forbidden” ports.
4. If after looking at the SVLAN, the switch does not have any ports to which it will send the frame, it won’t
check the port filter.
