I have two 6513s configured in a VSS-SSO pair. These switches provide power to Cisco IP phones (various models).
I am seeing an error that says
C6K_POWER_SW1-4-PD_NOLINKUP: The device connected to 20/25 is powered up but its link is not up in 5 seconds: Therfore, power is withdrawn for the port
There isn't even a port 20/25 on the switch!
What is this?
