mac address learning of actual physical port on lacp

MP18 — Fri, 22 Feb 2019 15:54:38 GMT

We have LACP aggregate connection to the switch.

is there any way i can learn the mac address of the switch port itself on the PA ?

Right now PA only shows me mac address of chassis of the switch.

I may be misunderstanding the question, but isn't the firewall just learning the mac to the relevant IP addresses it is communicating with. unless the switch ports have an IP associated to it and performing L3 functions, the firewall wouldn't need to know their mac

in our setup switch port has layer 3 IP address.

Yes you got it right i mean to say exactly what you said below

isn't the firewall just learning the mac to the relevant IP addresses it is communicating with
