Hi,

recently I made update of my FortiGate's 60E working in HA.

I notice after update has changed MAC address of Hardware switch, Internal1 where got connected all VLANs, from something like xx:xx:xx:09:00:12 to xx:xx:xx:09:00:03.

Is it normal, or I missing something.

In cluster, Primary Fortigate after update is this same Fortigate.

I'm curios because we had also EMS, and configured On-Fabric Role Sets with Local IP/Subnet and MAC, and after update and MAC change some FortiClients think are off fabric because of MAC not right.

I forgot the specific version. It may be that the HA MAC change BUG will appear when 6.2.x is upgraded. This is a BUG, which has been fixed in the newer version.

clients will not be off fabric because of the MAC change.

If you want to verify the mac address of the interface , you can use below command to verify the physical & virtual mac of device.

# diag hardware deviceinfo nic <port-number> , you will see below in the output
Current_HWaddr XX:XX:XX:02:94:be
Permanent_HWaddr XX:XX:xx:02:94:be
