no sticky voip-phone mac-address, why/ how ?

Unanswered Question
Jul 10th, 2008

Hi there,


We're having a port-security problem while using a voice vlan on a switch interface (WS-C4506).


The objective:


A Cisco voip-phone and a user-desktop machine connected to the same interface. The mac addresses

of both these devices should be flagged as being sticky so that whenever (one of) these

devices gets removed and a third device/ mac-address is connected to the interface, the interface will be port-sec

error disabled.


Now it seems that only the mac-address of the accesvlan device, the user desktop, gets flagged as being

sticky, while the mac-address of the voip-phone turns out to be dynamic.


Is there a way to make the voip mac-addres sticky? Or is there another way to reach the objective as described?


Any help is much appreciated!


Here the config of the interface + a show port-sec int
