Trunk voice vlan

[Anna_Katona]

Hello!

I have a network: switch Cisco 3750 and IP-phones. Phones are in voice vlan. On switch I have a "trunk" port.
 

Monitor session shows that voice traffic doesn't go through the trunk port (although data traffic goes through).

I have a standard configuration of the port:

(config-if)#switchport mode trunk

(config-if)#switchport trunk encapsulation dot1q

(config-if)#switchport trunk allowed vlan 101, 102.

What is the problem?

hello

i guess your voice. vlan is either 101 or 102 ?

is the voice vlan created at the layer 2  level and it propergated to all switches in your vtp domain

Lastly is the vlan allowed over either side of the trunk
