 * 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.

 * 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}
