I have a cisco switch which has a trunk to a PA device. On the switch it is configured switchport trunk allowed vlan 120,766,767. How do I add the corresponding configuration on the PA end?
The AE2 int already has the .120, .766 and .767 sub interfaces. Does it need configuring to allow the same as the Cisco switch and by creating the sub interfaces is that basically the same as trunk allowed vlan?

Hello,
Looks like you have it. Cisco would be configured as a trunk and on the PAN side its sub interfaces and make sure they are tagged and the vlans defined.

Hello @M.Allen
in addition to what Otakar mentioned here are KBs for Firewall sub-interface configuration:
