Nortel 5520 switch not passing class 2 traffic

[Steeple]

Hi there.

I have a Nortel 5520 which I have been informed is not forwarding class two traffic. The switch is a pretty basic install with two (3 if you include management) Vlan's, the 2 configured VLANs are for Voice and Data and have QoS configured for both.

Anyone got an idea where I need to look for to resolve this?

Thanks

What is "class 2 traffic"?

Does the switch have IP routing enabled, or are both VLANs trunked to a layer-3 device elsewhere that does the routing?

Perhaps they meant to say "Layer 2" traffic?
