What's procedure for configuring QoS in Single Site

Q: What's procedure for configuring QoS in Single Site?

A: Quoted for ShoreTel

QoS exists at multiple OSI model layers where the queuing occurs at layer-3 and also layer-2 depending on whether the traffic is being routed and/or switched. With a single site, single Voice VLAN deployment, layer-2 QoS is the only configuration that is required for prioritization.
Implicitly or Explicitly Universal LAN QoS/CoS Configuration Steps
• Enable QoS
• Configure queues, identifying priority queue, type, congestion-avoidance, bandwidth, buffer size, etc.
• Map CoS values to ingress and/or egress port queues and thresholds.
• Map DSCP values to ingress and/or egress port queues and thresholds.
• Configure DSCP map, which maps layer-2 CoS values to layer-3 DSCP values or visa versa.
• Bind QoS configuration to all VoIP switch interfaces.
• Validate configurations.
