I have been working on this one for the last few days. I saw a post from some time ago when someone did it with Comware/ HPE device and I tried to mimic it with no luck.
I have a Palo Alto that I have an aggregate ethernet set up on. On my switch it connects to, I have my VLAN, the interface VLAN, and the port configured as a trunk with just the interfaces then I tried it with a LAG. What I see is that the Palo Alto says it is up, but my switch says it is down and I cannot ping the IP I am using on the AE on the Palo Alto. This is what I have done on the switch side:
VLAN 2
description Palo Alto AE
interface vlan 2
description Palo Alto AE
ip address 10.2.2.2/24
ip ospf 1 10.2.2.2
interface 1/1/1
description Palo Alto AE
vlan trunk native 1
vlan trunk allowed 1,2
This showed up on the switch for a little bit until I started trying to ping it. When it didn't ping I rolled the fiber then tried and still got nothing and then rolled it back and the port showed down so I tried as a LAG:
interface lag 2
description Palo Alo AE
vlan trunk native 1
vlan trunk allowed 1,2
lacp mode active.
I still was unable to ping the IP of the AE on the Palo Alto. I am not sure whether I need a LAG or a just using the interfaces would be ok or maybe I am going about this the wrong way?
