The link light on the 4550 Gi6/4 is solid green, but
The link light on the 3560 Gi0/3 goes from amber to green about once a second.
I haven't tried on all ports, but on a couple of the access-ports the connection to the rest of the network (through the trunk) is slow or non-existent (times out).
I originally had it on 3560 port Gi0/2 and the console was logging "Gi0/2 LinkDown | Gi0/2 Link Up" messages (i'm guessing once every 15 seconds, but more random). Since I moved the trunk to Gi0/3, the console messages do not show up, but the link light still goes from green to amber.
Any ideas? I've taken out the fiber, doesn't look dirty. Canned Air cleaned.
