we have installed a Firepower 2140 in HA environment. I have a problem in showing all interfaces from the Secondary Firewall.
I can see only the following Interfaces NIM (4x10G in NIM 1 Module) on the Primary firewall which is 1/13,1/14,1/15,1/16 but i cant see the ports from Secondary e.g. 2/13, 2/14, 2/15 , 2/16. I want to make Portchannel on these ports connected to NIM 1 in both firewall. i cant see the ports from both modules while making a portchannel. The HA is working fine. Any body has the seen the problem.

When you create a portchannel it will replicate the configuration to the secondary unit in an FTD (or ASA) HA pair. So you do not need to (and cannot) select interfaces exclusively on the secondary unit. Just create it using the desired interfaces on the primary and it replicates when the config syncs.
