Hi there, 

Why would you connect half of your port-channel to a device that is not going to pass traffic?

The typical way of connecting a active/passive HA pair to a stack of switches would be to take two ports from each firewall and connect them across the switch stack:

 

PA1: Eth1 -> gi1/0/1  - Po1

PA1: Eth2 -> gi2/0/1  - Po1

PA2: Eth1 -> gi1/0/2  - Po2

PA2: Eth2 -> gi2/0/2  - Po2

 

You would then configure pre-negotiation on the passive port-channel to ensure sub-second failover.

LACP and LLDP Pre-Negotiation for Active/Passive HA (paloaltonetworks.com)

 

cheers,

Seb.
