Saving VLAN Configuration
The
configurations of VLAN IDs 1 to 1005 are always saved in the VLAN database
(vlan.dat file). If the VTP mode is transparent, they are also saved in the
switch running configuration file. You can enter the copy running-config
startup-config privileged EXEC command to save the configuration in the startup
configuration file. To display the VLAN configuration, enter the show vlan
privileged EXEC command.
When you save
VLAN and VTP information (including extended-range VLAN configuration
information) in the startup configuration file and reboot the switch, the
switch configuration is selected as follows:
• If the VTP mode is
transparent in the startup configuration, and the VLAN database and the VTP
domain name from the VLAN database matches that in the startup configuration
file, the VLAN database is ignored (cleared), and the VTP and VLAN
configurations in the startup configuration file are used. The VLAN database
revision number remains unchanged in the VLAN database.
• If the VTP mode or
domain name in the startup configuration does not match the VLAN database, the
domain name and VTP mode and configuration for the first 1005 VLANs use the
VLAN database information.
• If VTP mode is
server, the domain name and VLAN configuration for the first 1005 VLANs use the
VLAN database information
