* Add an IP Address to an interface or remove and IP Address from an interface.
* The IP Address can be an IPv4 or an IPv6 address. Interfaces may have multiple
* IPv4 and IPv6 addresses. There is no concept of primary vs. secondary
* interface addresses; they're just addresses.
*
* To display the addresses associated with a given interface, use the command
* '<em>show interface address <interface></em>'.
*
* Note that the debug CLI does not enforce classful mask-width / addressing
* constraints.

* @cliexpar
* @parblock
* An example of how to add an IPv4 address to an interface:
* @cliexcmd{set interface ip address GigabitEthernet2/0/0 172.16.2.12/24}
*
* An example of how to add an IPv6 address to an interface:
* @cliexcmd{set interface ip address GigabitEthernet2/0/0 @::a:1:1:0:7/126}
*
* To delete a specific interface ip address:
* @cliexcmd{set interface ip address GigabitEthernet2/0/0 172.16.2.12/24 del}
