We are having some strange behavior with an REP segment. Several times a day we get a link failure and the following message is in the ME3400 switch that drops the link. We are monitoring the CPU utilization and see no spike during the time that this happens. Also it seems to make its way around the ring with the same error happening in each switch. We have ensured all devices have the same rep admin vlan and all IOS images are the same (12.2(58)SE2). I have also verified that every switch has matching vlans. We only have 12 devices in the ring so I don't think we are near the limitations of REP. Any help would be greatly appreciated. The LSL timers are default at 5000ms.
