Chapter 12 Configuring VLANs
Displaying VLANs
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. To
view normal-range VLANs in the VLAN database (1 to 1005,) use the show VLAN configuration
command (accessed by entering the vlan database privileged EXEC command). For a list of the VLAN
IDs on the switch, use the show running-config vlan privileged EXEC command, optionally entering a
VLAN ID range.
Table 12-3 lists the commands for monitoring VLANs.
For more details about the show command options and explanations of output fields, refer to the
command reference for this release.
Step 8
exit Exit from config-vlan mode, and return to global configuration mode.
Step 9
interface interface-id Enter the interface ID for the routed port that you shut down in Step 4.
Step 10
no shutdown Re-enable the routed port. It will be assigned a new internal VLAN ID.
Step 11
end Return to privileged EXEC mode.
Step 12
copy running-config startup config 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.
