Entering CLI Commands
The switch CLI uses several techniques to help you enter commands.

Using the Question Mark to Get Help

Enter a question mark (?) at the command prompt to display the commands
available in the current mode.
console(config-vlan)#?
exit To exit from the mode.
help Display help for various special keys.
ip Configure IP parameters.
ipv6 Configure IPv6 parameters.
protocol Configure the Protocols associated with
particular Group Ids.
vlan Create a new VLAN or delete an existing
VLAN.
Enter a question mark (?) after each word you enter to display available
command keywords or parameters.
console(config)#vlan ?
<vlan-list> <1-4093> - separate non-consecutive IDs
with ',' and no spaces; Use '-' for
range.
protocol Configure Protocol Based VLAN
parameters.
If the help output shows a parameter in angle brackets, you must replace the
parameter with a value.
