We've a PA-3050 up and running for over a year now. It is configured with an agregated interface with LACP enabled (mode active, transmission rate Fast). These interfaces are attacheced to a procurve 5406 where the interfaces on the procurve are configured as a trunk of the type lacp.
This was running fine till now. Last 3 days the connection on the aggregated interface was gone for about 10 minutes. During this period the system log is filled with these kind of messages:
lacp-up,ethernet1/1,0,0,general,critical,LACP interface ethernet1/1 moved into AE-group ae1
lacp-up,ethernet1/2,0,0,general,critical,LACP interface ethernet1/2 moved into AE-group ae1
nego-fail,ethernet1/2,0,0,general,critical,LACP interface ethernet1/2 moved out of AE-group ae1
nego-fail,ethernet1/1,0,0,general,critical,LACP interface ethernet1/1 moved out of AE-group ae1
I found this article, and this seems to be the case. (the l2ctrld.log is filled up with these messages). However: I have no idear how to fix this.
