Description

One of the PoE enabled interface on customer's switch is not coming up

Symptoms

PoE was found to be administratively off.

 

Solution

We followed the below steps to isolate the issue:
  • No PoE device was connected to the port.
  • An AP was moved from one port to another. For example: ge-0/0/0 to ge-0/0/1
  • We attempted to bounce the port and PoE via MIST and CLI with no changes.
  • The last flap for the interface still showed as 2 weeks ago, even after bouncing the port.
  • We extracted the logs but was not able to find any significant logs related to the issue.
  • Hence we proceeded with RMA and marked for RA.
