350 Bridge "lost authentication with parent"

hi.

I have installed 350 series bridges to connect two buildings. the distance is 50m. the software running on the bridges is 12.02T1.

the problem is that the noneroot bridge initiates "lost authentication with parent" approximately every 30 minutes. at this time the connection to the root brodge is interrupted for 30 sec.

i tried to rise the transmit power, but it doesn't solved the problem.

do have anybody an answer for this problem?

regards. Marcel

Marcel,

Sounds like you have hit the infamous CSCdz03100

This is fixed in 12.03T

Marcel,

What authentication method are you using ? If it is EAP what is the session time out on your ACS set to ?

Whe you see these drops do you see lots of CRC errors or any sign of congestion such as hold offs and discards ?

David,

the authentication method is leap and the session time out is 600.

on the link are quite a lot of crc errors.

i build the bridge connectio in the lab, we have the same behavior without productive traffic on the link.
