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