C2960X - %ILPOWER-5-IEEE_DISCONNECT - PD removed

[Jean Zilli]

Dear all

I've had some issues with my IP phones during the calls. It has shown me on the Phone's display "Network down" and getting mute in the middle of the calls.

I checked the logs on the access switches (C2960X) and appeared logs of interfaces like:

Dec 11 18:41:44 MET: %ILPOWER-5-IEEE_DISCONNECT: Interface Gi1/0/42: PD removed
Dec 11 18:45:22 MET: %ILPOWER-5-POWER_GRANTED: Interface Gi1/0/42: Power granted
Dec 11 20:30:07 MET: %ILPOWER-5-IEEE_DISCONNECT: Interface Gi1/0/39: PD removed

My IP phones are Grandstream GXP1625;

My access switches are C2960-X and are running into version 15.2(4)E2;

Below some outputs of one interface has been crashed:

Hi....

      Could you provide the interface configuration from your switch?

      Did you try with another phone or this problem occurs with all of them?

      Try to connect your phone in another interface to verify if this problem occurs in another port.

regards,

Fulvio

Hello I would not say all but several IP phones. Here are the port configs: Switch#sh running-config interface Gi1/0/42 Building configuration... Current configuration : 514 bytes ! interface GigabitEthernet1/0/42 description Client switchport access vlan 33 switchport mode access switchport voice vlan 65 switchport port-security maximum 2 switchport port-security violation restrict switchport port-security no logging event link-status srr-queue bandwidth share 1 20 50 30 priority-queue out no snmp trap link-status mls qos trust device cisco-phone mls qos trust dscp spanning-tree portfast edge spanning-tree bpduguard enable service-policy input PM_QOS_PORT_INPUT end Thank you.

The configs look good. The "same" configs that I used for my Phone devices...

Did you check what is the power recommendation for your phones?
Try to check what is the minimum power (watts) value that you need to configure for this phone model.
