CLI Command Modes
The supported commands can vary depending on the version of IOS software in use. To view a
comprehensive list of commands, enter a question mark (?) at the prompt.
Switch(config)# ?
To exit global configuration command mode and to return to privileged EXEC mode, enter the end or
exit command, or press Ctrl-Z.
Interface Configuration Mode
Interface configuration commands modify the operation of the interface. Interface configuration
commands always follow a global configuration command, which defines the interface type.
Use the interface interface-id command to access interface configuration mode. The new prompt means
interface configuration mode.
Switch(config-if)#
The supported commands can vary depending on the version of IOS software in use. To view a
comprehensive list of commands, enter a question mark (?) at the prompt.
Switch(config-if)# ?
To exit interface configuration mode and to return to global configuration mode, enter the exit command.
To exit interface configuration mode and to return to privileged EXEC mode, enter the end command,
or press Ctrl-Z.
config-vlan Mode
Use this mode to configure normal-range VLANs (VLAN IDs 1 to 1005) or, when VTP mode is
transparent, to configure extended-range VLANs (VLAN IDs 1006 to 4094). When VTP mode is
transparent, the VLAN and VTP configuration is saved in the running configuration file, and you can
save it to the switch startup configuration file by using the copy running-config startup-config
privileged EXEC command. The configurations of VLAN IDs 1 to 1005 are saved in the VLAN database
if VTP is in transparent or server mode. The extended-range VLAN configurations are not saved in the
VLAN database.
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 the 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
the commands except shutdown take effect when you exit config-vlan mode.
