Network Bridge Loop

[sonal_tw]

Hi,

I am using 1200 series 15 APs and getting the following error message once in a while (once or twice a day) on most of the APs.

Network Bridge Loop: Received packet from Self destined to [AWC Mcast AP-Only]014096ffff00 on port "emac0"

There are about 15 APs inside the building and current setup is adjacent APs use different channels.

Any ideas greatly appreciated.

Thanks

Sonal

Hi Sonal,

I believe that this is the same as a post in another topic on here

Pretty much the problem is what the message says

A packet from the radio port was seen on the ethernet port indicating a loop

I would look for any WGB's that might accidently have had the ethernet port plugged into the main lan

You can also get this, I believe, if one of the APs is accidentally configured as a repeater.
