IP phones on alcatel switches

[Yanesh]

Hi guys,
Hope you are doing fine. Actually i am stuck with a configuration. The issue is that:
I have one voice vlan and two data vlan. And IP phones should be connected to one port and we should be able to plug one pc for data behind the IP phones.

data: vlan 20, 30
voice: vlan 70

If i configure one port trunk to allow vlan 70 and and change the native vlan 1 to 20. I was supposed to get data from vlan 20 behind the IP phone becuse the IP phone can untag the vlan 70.

Now i need to get vlan 30 behind the IP phone. How should i proceed??

Regards

A port can only have one default VLAN, so you would need to change the default VLAN of the port on the switch from 20 to 30.

If your phone was on port 1/1, then you started with

show vlan port 1/1

20 default
70 qtagged

Issue the command

vlan 30 port default 1/1

then

show vlan port 1/1

30 default
70 qtagged

A cleaner solution would be to use mobile ports with VLAN rules. This way you can dynamically assign data and voice devices to the appropriate VLAN on a mobile port without the need to modify the configuration on a port by port basis. Just remember to use the VLAN mobile port tag option so as to allow the 1Q voice VLAN to work on the mobile port (by default 1Q ports cannot be mobile).
