VLAN Configuration in Global Configuration Mode
If the switch is in VTP server or transparent mode (see the
you can configure VLANs in global and config-vlan configuration modes. When you configure VLANs
in global and config-vlan configuration modes, the VLAN configuration is saved in the vlan.dat files. To
display the VLAN configuration, enter the show vlan command.
If the switch is in VLAN transparent mode, use the copy running-config startup-config command to

startup configuration, use the show running-config and show startup-config commands to display the
VLAN configuration.
