CLI Command Modes
Enter the vlan vlan-id global configuration command to access config-vlan mode:
Switch(config)# vlan 2000
Switch(config-vlan)#
The supported keywords can vary but are similar to the commands available in VLAN configuration
mode. To view a comprehensive list of commands, enter a question mark (?) at the prompt.
Switch(config-vlan)# ?
For extended-range VLANs, all characteristics except MTU size must remain at the default setting.
To return to global configuration mode, enter exit; to return to privileged EXEC mode, enter end. All
commands except shutdown take effect when you exit config-vlan mode.
VLAN Configuration Mode
You can use the VLAN configuration commands to create or modify VLAN parameters for VLANs 1 to
1005. Enter the vlan database privileged EXEC command to access VLAN configuration mode:
Switch# vlan database
Switch(vlan)#
The supported commands can vary depending on the version of software in use. To view a
comprehensive list of commands, enter a question mark (?) at the prompt.
Switch(vlan)# ?
To return to privileged EXEC mode, enter the abort command to abandon the proposed database.
Otherwise, enter exit to implement the proposed new VLAN database and to return to privileged EXEC
mode.
Line Configuration Mode
Line configuration commands modify the operation of a terminal line. Line configuration commands
always follow a line command, which defines a line number. Use these commands to change terminal
parameter settings line-by-line or for a range of lines.
Use the line vty line_number [ending_line_number] command to enter line configuration mode. The
new prompt indicates line configuration mode.
This example shows how to enter line configuration mode for virtual terminal line 7:
Switch(config)# line vty 0 7
The supported commands can vary depending on the version of software in use. To view a
comprehensive list of commands, enter a question mark (?) at the prompt.
Switch(config-line)# ?
To exit line configuration mode and to return to global configuration mode, use the exit command.
To exit line configuration mode and to return to privileged EXEC mode, enter the end command, or press
Ctrl-Z.
