Overview
This command creates a user-defined DHCP option. Options with the same
number as one of the pre-defined options override the standard option definition.
The pre-defined options use the option numbers 1, 3, 6, 15, and 51.
You can use this option when configuring a DHCP pool, by using the
option
command.
The
no
variant of this command removes either the specified user-defined option,
or removes all user-defined options. This also automatically removes the
user-defined options from the associated DHCP address pools.
