Hi...You can configure two L2 interfaces on the PA500 with L3 forwarding and VLAN tagging to support your VLANs.  Define virtual L3 interfaces, one per VLAN, which will act as the default gateway for all users/devices.

Since you have 2 switches for failover, you should consider adding a 2nd PA500 for high availability.  Otherwise if the PA500 is unavailable, your services will be interrupted.


About port channel , it`s possible to do ? with cisco ?

Best Regards.

Yes you can do port aggregation between PAN and a switch.

For example following setup:

PAN1 - 2 cables - SWITCH1

PAN2 - 2 cables - SWITCH2

SWITCH1 - 2 cables - SWITCH2

See following threads for more info regarding aggregated interfaces:

Aggregation of ethernet on PA-4050 with Cisco switch

PA 5050 Aggregate Interfaces

The PA500 does not support link aggregation at this time.  Thanks.

Only 4000 Series and 5000 Series Support Port Channel ?

Best Regards.

I had missed that currently only 4000 and 5000 series support aggregated interfaces.
