    QoS Overview QoS Overview The 7210 SAS D, E are designed with QoS mechanisms on both ingress and egress to support multiple services per physical port. The 7210 SAS D, E have extensive and flexible capabilities to classify, police, shape, and mark traffic.

  • Page 19: Qos Policies

    QoS Policies QoS Policies 7210 SAS D, E QoS policies are applied on service ingress, access ports, egress and access uplink ports and define: • Classification rules for how traffic is mapped to forwarding classes • Forwarding class association with meters and meter parameters used for policing (rate- limiting).

    Buffer pools cannot be created or destroyed in the 7210 SAS. The default pools created by the system are distributed among various ports. The 7210 SAS D, E only support port egress buffer pools. The egress buffer pools are distributed as access uplink egress buffer pool and access egress buffer pools. During system initialization, based on the maximum number of ports to be supported for access and access uplink, the total buffer is distributed into the access egress buffer pool and the access uplink egress buffer pool.
