802.1Q VLAN Configuration
This chapter describes the Matrix system’s capabilities to implement 802.1Q virtual LANs
(VLANs). It documents how to:
• Create, enable, disable and name a VLAN.
• Review status and other information related to VLANs.
• Assign ports to a VLAN and filter unwanted frames on one or more ports
• Assign a VLAN to a MIB-II interface in order to view statistics for the VLAN Set VLAN
constraints in order to control the filtering database to which VLANs are allowed to belong.
• Use GVRP (GARP VLAN Registration Protocol) to control and propagate VLAN knowledge
through the network.
• Create a secure VLAN for device management security.
7.1 VLAN CONFIGURATION SUMMARY
Virtual LANs allow the network administrator to partition network traffic into logical groups and
control the flow of that traffic through the network. Once the traffic and, in effect, the users creating
the traffic, are assigned to a VLAN, then broadcast and multicast traffic is contained within the
VLAN and users can be allowed or denied access to any of the network’s resources. Also, some or
all of the ports on the device can be configured as GVRP ports, which enable frames received with
a particular VLAN ID and protocol to be transmitted on a limited number of ports. This keeps the
traffic associated with a particular VLAN and protocol isolated from the other parts of the network.
NOTE: The device can support up to 4094 802.1Q VLANs. The allowable range for
VLANs is 2 to 4094. As a default, all ports on the device are assigned to VLAN ID 1,
untagged.
