Alcatel on Cisco Switch

Hi, need help to connect Alcatel on a Cisco 3750/4500 switch with a PC connected behind the Alcatel phone.
Since Alcatel phone does not understand “sw voice vlan” command, had to

had to create switch port as trunk
native vlan for data
and tagged vlan for voice
now i want to enable dot1x
but dot1x is not supported on trunks

Any thoughts

Cisco voice vlan with alcatel ip phones work fine, you just have to put the switchport in the voice vlan and then configure the phone with that vlan , if you want you can use a alcatel feature that gives the vlan id to the phone by dhcp you can use this also,by considering you lcatel phone system is recent.


interface FastEthernet2/2
switchport access vlan 10
switchport mode access
switchport voice vlan 20

** no need to create trunk port also..

The only thing tha you have to put is the voice vlan id in the alcatel phones by manually or by dhcp.

Use DHCP to tell the phone which VLAN (Means your voice vlan)to use for tagging, and the configuration file it downloads from the TFTP server contains info for the phone to tag CoS and DSCP values.  Use DHCP Option 176 to do this.  PCs and other devices that don't need the Option 176 information simply ignore it.

These confiuration are tested and works fine.
