I am trying to troubleshoot my VoIP phone not powering up when I connect it to my fa 0/1/0 on a 3825 with an HWIC-D-9ESW with the PoE option installed. The phone used to work but just stopped. When I plug it into any port on the HWIC the power LED blinks about once every 6 seconds. I would like to see if I can capture any logging the port is doing to further analyze this problem.
Appreciate any help.
