Short answer: Yes—if those port‑channels are configured as VLT peer‑LAGs, traffic can use both switches at the same time. But because your firewalls are HA Active/Passive, only the active firewall’s LAG will forward user traffic at any given moment. The passive firewall’s LAG is typically down or blocking until failover.
