FPR 1120 interface issues

[Artezys79]

Hi All,

I have frp 1120 configure with single interface and 5 subinterface, where one goes into the switch secong goes onto the FTDV 1 and third is to FTDv 2 and other two DMZ on the router. Access policy is proven to be working as it was operational for a few month and suddenly stopped.

The weird thing is that on the physical interface one subinterface, leading to the switch works well however other four have adjacency error, even DMZ cannot be reached from working subinterface.

Actions taken, tried to rebuild subinterfaces but nochange, tried to completely disable access policy with no change. ARP on router only have management, outside, inside and only one operational vlan records.

arp issue' must likely you not config correct vlan in trunk in SW' or missing add vlan to SW
