@Sethupathi,

What ports are you utilizing for HA2?

I was wondering the same.  What is your hardware type @Sethupathi  @simsim ?  If you're not using the dedicated HA2 port and the box is under heavy utilization the HA2 port and it's functionality will occur via the DP.  With the DP being under load it's possible HA functionality could be affected.

Re: ha2 keep alive

Hello,

Ifthe two are not connected directly, i.e. something like a switch or router in between the two PAN's, I would suggest also setting up HA1 and HA2 backups as a best pratice.
