FTD 4140 interfaces starting from Eth1/5 - Eth1/8 and no interfaces mentioned under Port Channel

[damode]

Hi, I have been handover an FTD 4140 HA setup. Can someone please explain why this FTD is showing interfaces only from Eth1/5-Eth1/8 ?

Also, when I checked the PO 17 to see which interface its using, it didnt show any interface. How is this possible ?

Port-channels for this platform is configured not on FMC, but on Firepower Chassis Manager (FCM).

The reason for Eth1/1-4 not being visible on FMC could be because these interfaces are the members of Po17 and Po23 that are configured on FCM
