Anyone seen this before?

Call Manager version 5.1.1.3126-1

Error:

"Update failed. [491] The specified name has invalid characters or is not formatted correctly for this device type."

The MAC address field on the page saids use last 10 characters, which

I was doing. No spaces, etc.

I changed a character in the middle of the old MAC address from E to B

and it also failed to update.

Had a VG224 get a bad port, and RMA'd and tried to update the MAC

Address field on the gateway configuration page but it fails to

update. I had inititally tried using mac-address command on the VG224 Fast Ethernet to set it to old MAC and rebooted VG225 so it matched what CCM had but the ports did not register for some reason.

I was able to add a new gateway with the new MAC address just fine, but had to reconfigure all the ports and associate the DNs to them.

I have done this on CCM 4.x when replacing VG224's in past without problem. I've done a bug search and not finding anything. I found a bug on copying lines with a 7960 and this message, is that similar? That bug id saids it should be fixed this ccm version though.
