Hi all, We have had a problem with EAPS that has caused a high level CPU of the switches an the increase of traffic through the rings. A continuation I show the picture of the EAPS.
External plant had a maintenance which involved that the links in red (the shared port )got down, after two or three hours the link between SJL -LN got up and the problem started, the cpu increase and the traffic also.
These are the logs (SBJExtr had 30 minutes more):

And the state of the eaps in the nodes LN and SJL are the next one.
