%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error

Unanswered Question
Feb 9th, 2009

Hi,

I am seeing this error message contineously in one of our 3750 switches. None of the IP phones are getting powered in that switch. Please suggest whether this leads to any hardware / software issues.

%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi2/0/16: Power given, but power controller doesn't report Power good

Thanks in adv,

Guru

I have this problem too.

Hi Guru,

I don't recognise this exact message ("Power good"...) but normally it means that the switch has detected a POE device and has powered up the port however the link has still not come up. Are you certain the switch and phones are compatible?

Cheers

Hi

After removing the switch from stack and rebooting the switch the problem got resolved.

Any idea as i have to give root cause to customer.

Thanks

Some of the earlier POE devices had a maximum number of ports that could be powered. If you plug in too many devices, you won't get power on all the ports.

You can also check by giving the following command:

Switch#sh power inline

Secondly It could be a bug and getting the same syslog message for the Type 1 token ring patch port.

CSCed09484

When a type 1 Token Ring patch cable is connected to a PoE port, these syslog messages appear every 10 seconds:

-00:01:06: %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error,

here is no workaround. However, when a valid link partner is connected to the PoE port, it operates normally and without user intervention.

Just FYI

I had the same problemon a 3550-24PW switch which was solved by using the following command on all the fastethernet ports

Switch_Admin(config-if)#power inline delay shutdown 20 initial 100

All phones work now using PoE

Good luck

smartns04, thanks for that command. It helped me resolve a similar issue that I faced with my 3550 switch. But certainly not what the original poster encountered on the 3750.

Hi smartns04,

Thanks Man!! It really worked for me!! After the CUCM upgrade half of my IP Phones were not coming up because of this error. Your command helped me.

Same problems on C3560-48PS, running 12.2(55)SE6.

No possibillity to configure mentioned configuration on the interface.

We've than exchanged the switch, but problem still occured on the same port.

So might be the end-device be the problem? (Alcatel ipTouch)
