This morning, I had a switch go down. I found out that the uplink port failed. I searched the "show tech-support" for answers in the log. In the attachment, it shows show logging and continues with erros about link 1/0/49 failing and STP switching link 1/0/49 to blocking state. 1/0/49 is port 1/xg1 in the running-config near the bottom of the attachment. What would cause the port to fail for about 8 minutes and come back up on its own? Thanks in advance.
