Dear Friends
Today after a good weekend when I came back to my office, I figured out two our switches has problems with the redundant links. It would have consumed more time if I had no proper documentation. With time and experience I learnt that it is must to have good documentation about the Network.
In order to monitor the links I simply use What’s Up Gold from IP Switch. I have documented our network using Microsoft Visio with interface details, IP address details for each Switch . Since all the connection details were documented it was pretty easy for me to identify the port number in the core switch and to check the log what happened. One of the problems we faced was a defective fiber patch cord and other problem was a defective SFP module. Upon changing these two things we could able to fix this problem in matter of five minutes.
