VLANs on Fortigate

[darrencarr]

Guys I am experiencing a bit of an issue. I have two Fortigate 1000A' s that I am trying to connect over a L2 circuit. I only have one physical port available on each of the Fortigates so am trying to make use of VLANs. I have created the VLAN on each of the interfaces (Int 8). However when I patch into the Foritgate I get a MAC flapping issue. When I investigate further I have found that both VLANs are using the same MAC address 0009.0f09.0008 Is there anyway I can adjust this? I am guessing this is how the Fortigate creates its VLANs and the 8 at the end of the MAC relates to the interface number? Anyone experienced anything like this? I dont really want to start adjusting MAC addresses in the config if I am going to run into issues? I cannot upload the network diagram for some reason... will try again off another connection...

Hi g3rman I found what I was looking for in a HA configuration document. It would appear that all sub-interfaces (VLANs) are assigned the same virtual MAC as the physical interface. The Fortigate must simply manage this internally? (unique VLAN id' s). Thanks for all your help. We can close off this call. Darren
