183 * Add an IP Address to an interface or remove and IP Address from an interface.
184 * The IP Address can be an IPv4 or an IPv6 address. Interfaces may have multiple
185 * IPv4 and IPv6 addresses. There is no concept of primary vs. secondary
186 * interface addresses; they're just addresses.
188 * To display the addresses associated with a given interface, use the command
189 * '<em>show interface address <interface></em>'.
191 * Note that the debug CLI does not enforce classful mask-width / addressing
196 * An example of how to add an IPv4 address to an interface:
197 * @cliexcmd{set interface ip address GigabitEthernet2/0/0 172.16.2.12/24}
199 * An example of how to add an IPv6 address to an interface:
200 * @cliexcmd{set interface ip address GigabitEthernet2/0/0 @::a:1:1:0:7/126}
202 * To delete a specific interface ip address:
203 * @cliexcmd{set interface ip address del GigabitEthernet2/0/0 172.16.2.12/24}
205 * To delete all interfaces addresses (IPv4 and IPv6):
206 * @cliexcmd{set interface ip address del GigabitEthernet2/0/0 all}
