Firepower 2K Highavailability

Hello everyone

I am trying to deploy a pair of 2Ks with code version 6.2.2 in Highavailability mode.

My wish was to use the Etherchannel subinterfaces to perform this task (to use as Failover links) but those don't appear under the possible interfaces to choose (I only have the physical ones).

Is this a known bug or maybe feature 🙂 ?

Thanks in advance

Isaac Alves

The failover link (and the optional stateful failover link) must be dedicated connections between the two units.

If they were subinterfaces on an Etherchannel they would not be dedicated and thus that is not a supported configuration.

Hello Marvin

Thanks for your reply.

Following your line of thought I supose that the same goes for a normal trunk port, right?

Correct.

Subinterfaces would still be required on a non-etherchannel trunk so that would also be a non-dedicated interface.
