Hi guys,
I’m encountering a problem I never had before.
I have 3 cerberus with the same program, I set a MAC Address for each cerberus via FEZ Config:
1. 00:21:03:19:89:01
2. 00:21:03:19:89:02
3. 00:21:03:19:89:03
When I run my program the MAC Address is being overwritten and all 3 cerberus have the same MAC Address:
1. 00:21:03:00:00:02
2. 00:21:03:00:00:02
3. 00:21:03:00:00:02
Is this happened to someone before?
What can I do? Maybe set the MAC Address via software?
Thanks
Big
What do you read for mac using fez config?
What? I didn’t understand what you asked!
Gus is saying, I think, after you set the MAC address (with Fez Config) and then you run your app, please go back into Fez Config and see what MAC is shown. I think this is trying to see if your program is overriding the MAC or if the address is sticking or not… (I also assume he implied that when you read the mac address you were doing so within your app…
Correct and also try without your app. Set the max, reset the board and then read it back using fez config
Thanks to all, sorry for the late reply but I was at work.
I tried all you suggested:
I need to add a detail: actually I verified that Cerberus lose MAC Address only when connected in a LAN managed by a Layer 3 switch (HP 5406ZL). Can be the layer 3 switch the cause of MAC address lost/changed?
@ BigFoot - We will take a look.
@ BigFoot -
Not clear to me, the switch can not touch on MAC address, unless your related code are running.
Erase the application. Then use FEZ Config to set new MAC, when FEZ Config ask “Network configuaration has been saved successfully, do you want to reboot and run the firmware now”, Click Yes, then try read again. The MAC should be changed.
I don’t think it is related to switch, unless your program does. If so, please show your code.
I asked these because I just tried by FEZ Config and could not reproduce. Tested on 4.3.7.7 but I think the version is not important.
Hi,
You can also Try the following alternative, please let us know if it works…

Cheers,

@ Dat - I supposed could be the switch because it is the only one hardware that changes between testing the program at home and testing the program at office.
It’s happened again and I have another detail on this issue: it’s happened after 10 days that it was turned off.
After 10 days that it was turned off, I turned on cerberus to check the MAC Address through FEZ Config and MAC is returned to the “factory value” 00-21-03-00-00-02 instead of the MAC address I had set.
Anyway, I didn’t erase application so I’ll try.
I’ll take a look to the code snippet linked by @ Jay Jay.

@ BigFoot -
your code is too long and complex that we can not try here.
I see you called
try to set a fixed number and see what happens in next 10 days.
Or try a simple application there is only network.@ Dat - Ok, I’ll try with a smoother version (with only the network functionality).
Set a fixed value for static IP gives me some trouble because I have different class addresses between home and office.
If also the smoother version has the same issue, I’ll set a fixed value for static IP and I’ll test only at home.
I’ll keep you updated.
thanks again
