Displaying VLANs

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 database
configuration command (accessed by entering the vlan database privileged EXEC command).

switch resets, it will default to VTP server mode, and the extended-range
VLAN IDs will not be saved.
