Setting up HA and un-used x0 interface

Hi, In our setup the x0 interface is not used and as I understand it we have to link x0 on both the primary and backup units. My confusion is, Should the x0 interface be numbered with a different subnet to any other int or should it be unnumbered?. And which subnet should one use for monitoring? I manage the primary with an ip on interface x25 sfp+; should I pick an ip from the same range as my int x25?

    My 2700s in HA work without using X0. I use x16 for LAN, and then x18 is dedicated to HA tasks (has the two dots for "direct CPU access".

    It works great, and I haven't had an issue with it. My x0 still has the default IP assigned, and isn't connected physically to anything at all.

    HI Guys, Thanks for the input ... I tried with and without x0 connected and the firewalls HA'd. However, I had a console session running and there was a nag about; couldn't find x0 ... so I connected it directly for good messure :).

    So x0 is numberred with the default ip (a network which I do not use) and without management or the primary / secondary ips (would not be able to connect that way anyways).

    So, thanks muchly for the input and to the community manager for popping the question into the correct heading.
