Power Device detected and removed, how to solve?

Flavio Boniforti · ‎10-20-2011

Hello everybody.

On a Catalyst 3560 I have these messages showing up:

882492: Oct 20 10:14:28: %ILPOWER-7-DETECT: Interface Gi0/27: Power Device detected: Cisco PD

882493: Oct 20 10:14:29: %ILPOWER-5-POWER_GRANTED: Interface Gi0/27: Power granted

882494: Oct 20 10:14:29: %ILPOWER-5-IEEE_DISCONNECT: Interface Gi0/27: PD removed

The port has this config:

interface GigabitEthernet0/27

switchport access vlan 10

switchport mode access

switchport voice vlan 40

no logging event link-status

spanning-tree portfast

end

I connected the cable to port 26 and 37, both of them having the exact same config: the problem still persists.

What could it be and how could I solve this issue?

Thanks in advance.

Kind regards,

F.

hi flavio ,,

need more clarification for your problem !!!!

1. do you want to remove any logs message for interface power down ???

2 . are you telling that once you remove workstation from gi0/27 and connect it to some different port you see same message ??

- you can first clear these logs by using # clear logging buffer ......

In addtion to logs,please provide the output of "show power inline"

Flavio Boniforti · ‎10-20-2011

Hello Ankur.

I do not need the logs to be cleared, I just want the device connected to that port to go online.

Here some more output:

switch#sh int status | i 0/27

Gi0/27 notconnect 10 auto auto 10/100/1000BaseTX

switch#show power inline

Thanks again.

Hi,

you've got nothing connected to interface so POE is off.

Can you connect the Phone and do debug power inline and debug CDP packets

Regards.

Hello Alain.

I do have something connected on that port, otherwise it wouldn't constantly tell me that:

882492: Oct 20 10:14:28: %ILPOWER-7-DETECT: Interface Gi0/27: Power Device detected: Cisco PD

882493: Oct 20 10:14:29: %ILPOWER-5-POWER_GRANTED: Interface Gi0/27: Power granted

882494: Oct 20 10:14:29: %ILPOWER-5-IEEE_DISCONNECT: Interface Gi0/27: PD removed

Hi,

switch#sh int status | i 0/27

Gi0/27 notconnect 10 auto auto 10/100/1000BaseTX

This may be due to POE so can you turn off POE on the port then enable the debugs I asked then reenable POE and post outputs from the debugs.

Hello Alain.

I managed to do "power inline never", then I enabled "debug cdp packets" but the "debug power inline" does not exist. I thought it could be "debug ilpower port", thus I enabled it and then I re-enabled PoE on that port with "power inline auto".

This is what I got:

vxs02a2(config-if)#power inline auto

Still, I don't know what to do and what is happening.

Any further steps I could take?

Thanks!

Hmmmm ... Let's try a TDR cable test ...

1. Command: test cable tdr interface Gi 0/27;

2. Wait for about 5 to 7 seconds;

3. Command: sh cable tdr interface Gi 0/27;

4. Please post the complete output.

Flavio Boniforti · ‎11-17-2011

Here we go:

Interface Speed Local pair Pair length Remote pair Pair status

--------- ----- ---------- ------------------ ----------- --------------------

Gi0/27 auto Pair A 10 +/- 4 meters N/A Open

Pair B 11 +/- 4 meters N/A Open

Pair C 11 +/- 4 meters N/A Open

Pair D 11 +/- 4 meters N/A Open

Uhhhh ... how is this going to help?

The result tells me that NOTHING is connected to the cable.

If there's something connected the result will not be "OPEN" on all four pairs.

Flavio Boniforti · ‎11-18-2011

That's true, but it may be that this behaviour is originated from a faulty Cisco PD device, or what else do you think?

I'll take a walk and check WHAT is actually connected to that port. The weird thing is that *nobody* ever told nothing about something not workin...

Regards,

F.

Leo Laohoo · ‎11-18-2011

That's true, but it may be that this behaviour is originated from a faulty Cisco PD device, or what else do you think?

No. It means that the patch cable, 10 meters long, is plugged to nothing. Please verify that something is plugged and run the test again.

Flavio Boniforti · ‎11-18-2011

But if it'd be connected to nothing, why do I have those ILPOWER-DETECT/GRANT/DISCONNECT messages in the term mon?

Leo Laohoo · ‎11-18-2011

Loose cable connection?
