I have a strange problem on two links in my network that I can't figure out. I have problems with one 6509 1000BaseSX module that has two ports connecting to two other 6509's as redundant links. Every so often they will drop out of STP with "%PAGP-5-PORTFROMSTP:" error and soon after will come back. I first reseated the links and then replaced the patch cables but the problem keeps occurring every so often. They seem to run OK for about a week after I replaced the patches/reseted. Suspect the module might have something going on. Any ideas? Thanks.
Since there is no etherchannel configured, STP will run between the switches on both links and one of them will be in forwarding state and the other in blocking state. The above error messages could be due to a link flap. How often are you getting this messages ?
