show vlan

Use this command to display information related to one or more VLANs.

Syntax

show vlan [static] [vlan-list]

Parameters

static (Optional) Displays information related to all configured VLANs regardless of status.
vlan-list (Optional) Displays information for a specific VLAN or range of VLANs.

Defaults

If no options are specified, all information related to active VLANs will be displayed.

Mode

All command modes.

Usage

Static VLANs are manually created using the set vlan command set vlan, SNMP MIBs, or the WebView management application. The default VLAN, VLAN 1, is always statically configured and cannot be deleted. Only ports that use a specified VLAN as their default VLAN (PVID) will be displayed.

Example

This example shows how to display information for VLAN 1. In this case, VLAN 1 is named “DEFAULT VLAN” and it is enabled to operate. Ports allowed to transmit frames belonging to VLAN 1 are listed as egress ports. Ports that won‘t include a VLAN tag in their transmitted frames are listed as untagged ports. There are no forbidden ports (prevented from transmitted frames) on VLAN 1:

System(rw)->show vlan 1
VLAN     : 1           Status     : Enabled
FID      : 1           Name       : DEFAULT VLAN
