Apply Command on CISCO Router/Switch

Command

Apply

Use

This command applies any changes to the VLAN database but doesn’t exit the VLAN database. In fact, the exit command is a macro that runs the applycommand before exiting.

Syntax

Swtich(vlan)#apply

Example

In the below example we will enter the VLAN database, configure VLAN 99 and exit without using the exit or the apply command. Looking at show vlan brief afterwards, we see that VLAN99 was not created.

Cat1#vlan database
% Warning: It is recommended to configure VLAN from config mode,
as VLAN database mode is being deprecated. Please consult user
documentation for configuring VTP/VLAN in config mode.

Cat1(vlan)#vlan 99
VLAN 99 added:
Name: VLAN0099
Cat1(vlan)#^Z

This time we will use the exit command after creating vlan 99. Now we see the vlan was properly created.
