Cisco Switch 2900/2950: Display VLAN information
Knowing the commands to display configuration information about Virtual LANs (VLANs) is as important as knowing the commands to configure them. The commands here display information about all VLANs or a single VLAN by number or name.
All of these commands must be run from privileged mode. To view detailed information about all VLANs on the local switch, use:
# show vlan
To shorten the output and just display the highlights about all of the VLANs:
# show vlan brief
To display information about VLAN 3, use:
# show vlan id 3
This version of the command can be extended to look at multiple VLANs. For example, to view information about VLANs 1, 2, 3 and 10, use:
# show vlan id 1-3,10
For increased administratability, VLANs can be named. To view information about a VLAN by name, for instance the VLAN named 'engineering' use this command:
# show vlan name engineering

H3A VLAN (Virtual Local Area Network) makes a single physical switch behave like several separate switches. A host connected to one VLAN cannot communicate through the switch to a host connected to another (although a router can permit communication between VLANs if desired). Here's how to confi

Disable or turn off CDP on Cisco switches
H3Cisco Discover Protocol or CDP is a Cisco proprietary protocol that runs on all Cisco products. CDP allows devices to learn about neighboring devices (the ones attached directly to the switch) including information about their platform, IP address, the version of IOS or other OS, VLAN membershi
