If the switch is purely Layer 2, it would be difficult to classify VoIP
traffic ipso facto, as the factors that differentiate it from other
kinds of traffic are, by definition, >= Layer 3.
About the only thing you can do there is use segregated VLANs, and/or
take advantage of the native "voice VLAN" feature of certain Catalysts:

In an access switch to core where the connections are Layer 2, what is
the best method to a) classify voip traffic as it enters the access
switch and b) prioritize it via some queuing mechanism as it traverses
the trunk going to the core? Does anyone have sample configs for
something like this?
Pc <-> phone <-> access switch <-> core switch. Priority to VoIP traffic
on trunks.
