ILPOWER-3 Issue

[Shawn Williams]

We recently installed 3 2980X switches in a stack and now only after about 2 months we are getting reports of network disconnects.  After researching we are seeing the following errors in the log on a handful of ports.

%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi1/0/9: Power Controller reports power supply VEE under voltage and lockout

IOS Version 15.2(2)E4

These ports do not currently have POE devices plugged into them but each time the error occurs the port drops and the individuals lose network.

Thanks

Could be a software bug for POE

quick fix maybe to turn off the poe on one of the ports your having an issue with and see if it stops the problem

interface x/x

no power inline

or

power inline never

the syntax varies from device to device
