Configured Interfaces:

1. Management (192.168.20.5/24, fe80::225:90ff:fe32:2fa4/64)
2. Data 1 (192.168.21.5/24)

Choose from one of the following commands:

CREATE (for laggs - display if there are 2 or more interfaces)
EDIT (show if there are any interfaces to configure; should be. Options to confiure here: aliases, addresses, vlans -- maybe the list of interfaces that can be a part of a lagg, but this could be potentially tricky if one or more interfaces are in use)
DELETE (for laggs only)

      A: Yes (DHCP)

      A: No

         Q: Enter in an IPv4 CIDR, e.g. 10.0.0.1/16 [display-already-configured-CIDR-here-if-this-is-set]: 192.168.20.5/24

Q: Would you like to configure IPv6 [y/n]? y

   A: Yes
   A: Yes

      Q: Would you like to obtain an IPv6 address automatically [y/n]?

      A: No

         Q: Enter in an IPv6 CIDR, e.g. fe80::225:90ff:fe32:2fa4/64 [display-already-configured-CIDR-here-if-this-is-set]: fe80::225:90ff:fe32:2fa4/64

[NOTE: the following only make sense if either an IPv4 or IPv6 address has been configured for the interface]

Q: Would you like to setup an IPv4 alias [y/N]?

   A: Yes

      Q: Enter in an IPv4 CIDR, e.g. 10.0.0.1/16 [display-already-configured-CIDR-here-if-this-is-set]: 192.168.20.5/24

Q: Would you like to setup an IPv6 alias [y/N]?
