Configuring Virtual LANs (VLANs)
December 2005 © Foundry Networks, Inc. 11 - 59
Displaying VLAN Information
After you configure the VLANs, you can verify the configuration using the following methods.
NOTE: If a VLAN name begins with “GVRP_VLAN_“, the VLAN was created by the GARP VLAN Registration
Protocol (GVRP). If a VLAN name begins with “STATIC_VLAN_“, the VLAN was created by GVRP and then was
converted into a statically configured VLAN.
Displaying System-Wide VLAN Information
Use one of the following methods to display VLAN information for all the VLANs configured on the device.
Enter the following command at any CLI level. This example shows the display for the IP sub-net and IPX network
VLANs configured in the examples in “Configuring an IP Sub-Net VLAN with Dynamic Ports” on page 11-34 and
“Configuring an IPX Network VLAN with Dynamic Ports” on page 11-34.
Syntax: show vlans [<vlan-id> | ethernet [<slotnum>/]<portnum>]
The <vlan-id> parameter specifies a VLAN for which you want to display the configuration information.
The <slotnum> parameter is required on chassis devices.
The <portnum> parameter specifies a port. If you use this parameter, the command lists all the VLAN
memberships for the port.
