Cisco Catalyst C9200-48P and PoE

[gary_the_network_guy]

So I wanted to connect an IP Phone to my C9200, it is an Alcatel 8028 Deskphone by the way, The important part is that it is 

IEEE 802.3 af compatible and should work just fine.

The Phone just does not power on. I checked the standards 

sh int status

sh power inline

sh logging

but absolutely nothing, no mentions in the logs about PD.

Does anyone have experience with this, it does look to me that there is no PoE detection happening.

[Leo Laohoo]

Post the complete output to the following commands: 

• sh version
• sh power inline
• sh interface <PORT>

Hello,

what is currently connected to:

Gi2/0/30 auto on 26.1 XXX 4 30.0

What if you plug that device into GigabitEthernet1/0/2 ?

[balaji.bandi]

Show version , show inline power

also check some troubleshooting tips :

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9200-series-switches/215636-troubleshooting-power-over-ethernet-poe.html

[gary_the_network_guy]

Yes I already did, I checked out this section.

Non-Cisco powered device does not work on Cisco PoE switch

---

Follow these steps when a non-Cisco powered device is connected to a Cisco PoE switch, but never powers up, or powers up and then quickly disconnects from power (powers down). Non-PoE devices work normally.

Step 1: Use the 'show power inline' command to verify that the switch power budget (available PoE) is not depleted before or after the powered device is connected. Verify that sufficient power is available for the powered device type.

Step 2: Use the 'show interface status' command to verify that the powered device is detected by the switch when connected.

Step 3: Use the 'show log' command to verify that the powered device is not causing a controller error on the port. This if happening would be highlighted in a syslog.

Step 4: If powered device initially powers on and then disconnects, problem might be an initial current surge that exceeds a current-limit threshold for the switch port.

Step 5: Verify that the powered device is compatible with the Cisco switch. For example, if both units are standards-compliant, they should interoperate. CDP cannot be used to identify a non-Cisco device, and the switch must rely on accurate detection and classification when working with a non-Cisco device using layer 1 classification or LLDP.  Ensure LLDP is operational on switch port.

Few scenarios involving third party powered devices are described below.

[Georg Pauwen]

Hello,

sounds a bit like a physical problem. Does the 8028 work with the external power adaptor ?

[gary_the_network_guy]

I did not test that but that phone worked fine on a 2960-Switch.

[balaji.bandi]

If the Phone working on old 2960, this could be bug on Cat 9200 (C9200-48P 16.12.2) uplift to 17.X  and test it

[Leo Laohoo]

How much power does this phone require?

Is LLDP enabled (globally)?

[gary_the_network_guy]

it is an class 2 phone I think it requires 7W and yes LLDP and CDP are enabled.

[Leo Laohoo]

Alright, do a TDR. 

1. Command:  test cable tdr interface <PORT>
2. Wait for about 7 to 8 seconds
3. Command:  show cable tdr interface <PORT>
4. Post the complete output to #3.

[gary_the_network_guy]

I looked at the problem today again, I realized that the first switch in the switch-stack is blinking green/amber on some ports.

I connected the phone to the second switch in the same stack and it worked right away.

My question now is, what could the problem be on the first switch  in the switchstack.

[balaji.bandi]

Then connect the console cable to the Blinking switch and see what is wrong, make sure the switch joined the stack.

show switch will give you information

Downgrade the firmware of the switch.  Any version BUT 16.12.X -- That is all I am going to say.
