[hinajabeen]

Hello All,

I am facing some PoE issues in Cisco 9300, I wonder if anyone has experienced the same?

Hello,

that looks like a hardware failure. All the other ports appear to be good except this one. You might want to try an upgrade to one of the recommended XE releases:

Release Bengaluru-17.6.5 MD

Release Cupertino-17.9.4a MD

what is the end device connecting to this port - try change the Ethernet cable and test ?

is this only Port having issue ? have you tried different port is the same issue ?

as @Georg Pauwen  suggested try upgrading the IOS XE see any difference before you go other route for TAC.

[hinajabeen]

End device is the Polycom Handset. As of now, if we remove any working phone and try to connect it back it will not work. 

Tried to use new ports but same issue. 

There are few Access Points also on this switch but so far they are ok

[MHM Cisco World]

from all above 
the SW can not know the class of power so it failed 
try use lldp in this port ONLY and check power 
MHM

[hinajabeen]

Hi, lldo configure on this port only means? 

SHould I enable transmitt receive? 

#lldp ?
med-tlv-select Selection of LLDP MED TLVs to send
receive Enable LLDP reception on interface
tlv-select Selection of LLDP TLVs to send
transmit Enable LLDP transmission on interface
ucs-chassis-tlv Selection of ucs LLDP TLVs to send

[MHM Cisco World]

only add these under the interface 
receive Enable LLDP reception on interface
transmit Enable LLDP transmission on interface

and sure that you run lldp in global

first try disable CDP in this interface, if not work

I think its already disabled:

there is no lldp at all 

debug lldp packets <<- run this if you see lldp then it OK and there is bug or lldp mismatch if there is no packets then the cable is cut or the phone is dead
