We have 2 6513's that are linked via 2 10 gig interfaces, using an LACP channel.
I received an alert this aft stating that the far 6513 was unreachable and the port channel int PO3 had gone down, the 2 10 gig interfaces had also gone down on either side. 5 mins later PO3 had resestablished itself and has been fine since. I am trying to determine what happened.
Here is a port channel summary from both switches.
Switch 1
