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.

Port String Syntax Used in the CLI

For information on how to designate VLANs and port numbers in the CLI syntax, refer to "Port
String Syntax Used in the CLI" on page 4‐1.

Creating a Secure Management VLAN

By default at startup, there is one VLAN configured on the G‐Series device. It is VLAN ID 1, the
DEFAULT VLAN. The default community name, which determines remote access for SNMP
management, is set to "public" with read‐write access.
Note: The device can support up to 1024 802.1Q VLANs. The allowable range for VLAN IDs is 1
to 4093. As a default, all ports on the device are assigned to VLAN ID 1, untagged.
