Displaying Vlans - Cisco 3032 Software Configuration Manual

Displaying VLANs

Beginning in privileged EXEC mode, follow these steps to release a VLAN ID that is assigned to an
internal VLAN and to create an extended-range VLAN with that ID:
Command
Step 1 show vlan internal usage
Step 2 configure terminal
Step 3
interface interface-id
Step 4 shutdown
Step 5
exit
Step 6 vtp mode transparent
Step 7 vlan vlan-id
Step 8 exit
Step 9
interface interface-id
Step 10
no shutdown
Step 11
end
Step 12 copy running-config startup config
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.

Purpose
Display the VLAN IDs being used internally by the switch. If the VLAN
ID that you want to use is an internal VLAN, the display shows the routed
port that is using the VLAN ID. Enter that port number in Step 3.
Enter global configuration mode.
Specify the interface ID for the routed port that is using the VLAN ID,
and enter interface configuration mode.
Shut down the port to free the internal VLAN ID.
Return to global configuration mode.
Set the VTP mode to transparent for creating extended-range VLANs.
Note
Enter the new extended-range VLAN ID, and enter VLAN configuration
mode.
Exit from VLAN configuration mode, and return to global configuration
mode.
Specify the interface ID for the routed port that you shut down in Step 4,
and enter interface configuration mode.
Re-enable the routed port. It will be assigned a new internal VLAN ID.
Return to privileged EXEC mode.
Save your entries in the switch startup configuration file. To save an
extended-range VLAN configuration, you need to save the VTP
transparent mode configuration and the extended-range VLAN
configuration in the switch startup configuration file. Otherwise, if the
switch resets, it will default to VTP server mode, and the extended-range
VLAN IDs will not be saved.

VLAN Monitoring Commands
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.
This step is not required for VTP version 3.
