Is there a way to find out the physical interfaces used by a port channel in FTD 4110 or 2120 through FMC gui or FTD cli or from anywhere else?

I have lately realised that there is no way to actually figure out the physical interfaces used by a port-channel in FTD 4110s or 2120s or probably any FTDs through the FMC gui or FTD cli.

I asked TAC about this and they also advise there is no way to find that out.

But I thought I might still give a try here to see if anyone knows whether its possible ?

From the FMC GUI you can see it.

Devices > Device Management and edit the device. Then Interfaces > select and edit the port-channel. The first tab shows the currently selected member interfaces that have been configured.

Hi Marvin,

Please refer to the screenshot. Its not showing the physical interfaces allocated to the Portchannel.

For the 4100 and 9300 series it's slightly different. On those platforms we allocate physical interfaces via the on-box Firepower Chassis Manager (FCM) and not via Firepower Management Center (FMC).

Please check FMC and you should see the allocation of interfaces to Etherchannels.

This is honestly the most frustrating firewall to use, it's like little to no thought went into the development and even less into the documentation. You can't monitor port-channel member interfaces individually?? Like who doesn't think that's a necessity for any operations center
