          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

!

Each time this port is down and the log say:

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
