[c-nsp] 3750 with IP-BASE, QoS

[Joe Freeman]

I've inherited a site that's a mix of a 3750 stack and Force 10 gear.
the 3750 stack is where the layer 3 is happening between vlans in that
site. I have a need to implement QoS for some voice traffic.

Since the 3750 doesn't do QoS the way the routers do, I'm sort of at a
standstill..

policy-map Basic_QoS
class Voice1
! should be set to guarantee 32Mbps, low latency, priority queuing
class AgentApps
! should be set to guarantee 8M, normal queuing (mostly http and rdp traffic)
class Agent_Voice_other
! should be set to guarantee 12M, low latency, priority queuing
class class-default
! gets whatever is leftover/available


So, the question is... how do I map that into a qos config that works
(well) on the 3750?
