  1. Palo Alto Networks devices only support high-availability between 2 identical hardware or software models.
  2. If different Palo Alto models are connected in the same HA Pair, Error message is displayed and the device goes to suspended state
HA Group 1: Peer device platform model not matching; going to Suspended state.
