Update(s):
Date: 2010-06-08 11:40:32 UTC Close notice:
Problem was caused by a loop on a customer port. Because of a bug in the application of
access lists to customer ports, broadcast packets were not filtered.
Tomorrow during our maintenance window we will apply a patch which should address this
problem.
Date: 2010-06-08 08:20:44 UTC A problem on the DECIX.
Problem description:
We see flapping sessions all over the switches. Engineering is investigating.
Update 2010-06-08 07:57 UTC
We have isolated a suspect port which might be causing a loop on the platform. For now we
have shut down the suspicious port and continue to monitor the situation.
Update 2010-06-08 08:07 UTC
To answer the question why our MAC filter lists did not prevent this: There is an open issue
with Force10 because the filters are not applied to broadcast packets.
