mac address learning of actual physical port on lacp

[MP18]

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

we have point to point link with switch

show lacp aggregate-ethernet ae3

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

[reaper]

have you tried > show arp all

[MP18]

it only shows mac address of switch chassis not actual switch interface

[MP18]

is that default behaviour?
