Checking FTD interface mac address when in a port channel

[mrjelly]

Hello,

I am looking to see the MAC address of a FTD interface that is part of a port channel.

On the CLI all I can appear to do is run:

show interface PORT-CHANNEL and it shows one mac address, not one for each interface.

thank you

A firewall portchannel uses the MAC address of the first member interface. I verified on the switches this one connects to that they show the same in their MAC address table.

# show interface | i Inter|MAC|Member|Active
<snip>
Interface GigabitEthernet0/5 "", is up, line protocol is up
	Active member of Port-channel1
	MAC address 3890.a575.3bdf, MTU not set
Interface GigabitEthernet0/6 "", is up, line protocol is up
	Active member of Port-channel1
	MAC address 3890.a575.3be4, MTU not set
I<snip>
Interface Port-channel1 "", is up, line protocol is up
	MAC address 3890.a575.3bdf, MTU not set
  Members in this channel:
      Active:   Gi0/5 Gi0/6

the Port-Channel for FTD and all other Cisco platform use only one MAC address and this mac is mac of one of port member. 
so what you see is normal.

Thanks A Lot
