[dchavarria]

          Hi, I have a problem with a Switch 2960 and a telephone Avaya, its activate the command port securit, the topology is Switch 2960 port + Avaya telephone + PC and the configuration the port is:

Interface FastEthernet0/16

description PHONE-DEVTORO-PC

switchport mode access

switchport port-security maximum 2

switchport port-security

keepalive 4

!

Each time this port is down and the log say:

.Oct  2 19:03:23.559: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/16, putting Fa0/16 in err-disable state
.Oct  2 19:03:23.568: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address 0027.0000.0000 on port FastEthernet0/16.

Hello David.

Based on the logs, the mac address 00.27.00 belongs to Shenzhen Siglent Technology Co..

Did you check the physical connections? please verify it's in deed just a ip phone and PC daisy chain connected.

Please post the output of the command

Show port-security interface fa0/16.

Can you disconnect the PC and run the command Show mac address-table interface Fa0/16, share the output.

Regards.

Hi

The phone boots on the DATA vlan and the VOICE vlan.

MAC security need to be set to allow MAX 3 addresss or more.

Thanks
