HA1 and HA2 Links

L1 Bithead

Hi Guys,

I have configured each of my HA links to have backup links. I would like to know, are the backup links also sending and receiving traffic like port-channel in which both ports are active? Especially the HA2 if we want to have 20G or more links for session sync.

You don't gain any additional bandwidth capacity by enabling backup interfaces, it's not like creating a port channel or aggregate interface. 

Hi @BPry , noted but is it possible to have an AE interface to be an HA1 or HA2 so that we can bundle up those ports to increase bandwidth and having backup links altogether like the capability of ASA of Cisco? Thanks

You can only use an aggregate interface as an HA3 link because this interface requires a lot of bandwidth. for either HA1 and HA2 you don't need a lot of bandwidth so aggregates make less sense since you can add a secondary interface as backup
