FTD High Availability Failover using EtherChannel

I have 2 x FTD2110 managed by an FMCv, all v6.2.2. I'm trying to create an HA pair using an EtherChannel rather than a single physical link. However, only the physical interfaces are appearing in the dialog box to create the HA pair. The documentation states that "You can use any unused data interface (physical, redundant, or EtherChannel) as the failover link"though. This is really simple to do with ASAs... what am I missing when it comes to FTDs? Thanks!

Re: FTD High Availability Failover using EtherChannel

Just in case anyone else comes across this problem - ensure that you haven't named your Portchannel interface prior to creating the HA pair. If you have named your Portchannel, FMC thinks that it's unavailable for use as the HA link.

Have you assigned an IP address to the Etherchannel first?

 

I don't have one to check but I believe some other posters reported success after having done that.

Just tried it - no difference. Thanks for the suggestion though.
