Displaying VLANs

Use the no uni-vlan VLAN configuration command to return to the default (UNI-ENI isolated VLAN).
Entering uni-vlan isolated command has the same effect as entering the no uni-vlan VLAN
configuration command. The show vlan and show vlan vlan-id privileged EXEC commands also display
UNI-ENI VLAN information, but only UNI-ENI community VLANs appear. To display both isolated
and community VLANs, use the show vlan uni-vlan type command.
Displaying VLANs
Use the show vlan privileged EXEC command to display a list of all VLANs on the switch, including
extended-range VLANs. The display includes VLAN status, ports, and configuration information.

Trunking Overview

A trunk is a point-to-point link between one or more Ethernet switch interfaces and another networking device
such as a router or a switch. Ethernet trunks carry the traffic of multiple VLANs over a single link, and you
can extend the VLANs across an entire network. The switch supports the IEEE 802.1Q industry-standard
trunking encapsulation.

Purpose
Display characteristics for all interfaces or for the specified
VLAN configured on the switch.
Display parameters for all VLANs or the specified VLAN on the
switch.
Display UNI-ENI isolated or UNI-ENI community VLANs by
VLAN name.
Display UNI-ENI community VLANs and associated ports on the
