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.
Table 1-3 lists the commands for monitoring VLANs.
For more details about the show command options and explanations of output fields, see the command
reference for this release.
Configuring VLAN Trunks
These sections contain this conceptual information:
• Trunking Overview, page 1-15
• Encapsulation Types, page 1-16
• Default Layer 2 Ethernet Interface VLAN Configuration, page 1-17
• Configuring an Ethernet Interface as a Trunk Port, page 1-17
• Configuring Trunk Ports for Load Sharing, page 1-22
Step 7
vlan vlan-id Enter the new extended-range VLAN ID, and enter VLAN configuration
mode.
Step 8
exit Exit from VLAN configuration mode, and return to global configuration
mode.
Step 9
interface interface-id Specify the interface ID for the routed port that you shut down in Step 4,
and enter interface configuration mode.
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.
Note This step is not required for VTP version 3 because VLANs are
saved in the VLAN database.
