MVPDifferent MAC addresses on the same device
Why does the MAC address start differently for devices of the same series?
Does it have anything to do with the behavior?
device#1(active) : f4:15:63
device#2(standby) : 0:94:a1
thank you !
Hi,
You can see a list of all the OUI mac addresses for F5 here .
Are the two units in the HA pair definitely the same hardware platforms? I would have expected the OUI to match between the two devices if this was the case, but I'm not sure if there is a hard rule for this.No, it shouldn't have anything to do with the behaviour of each device.
neeeewbieYes, thank you
I checked that all of them are mac addresses of f5
I was having HA issues and was checking if that could be the cause of the problem.Thank you

Outside of you question you can always enable Configuring MAC masquerade (11.x - 17.x) . I am also interested why this is different as the only thing that came to mind is if you are on a vCMP quest vCMP guests running on different vCMP hosts are found to be using the same MAC address . I think the base mac is unique as if for some reason the auto generated mac addresses are the same because the base mac is the same this won't be good.
