Data Sheet

Advanced QoS

●

Standard 802.1p CoS and DSCP field classification are provided, using marking and

reclassification on a per-packet basis by source and destination IP address, source and

destination MAC address, or Layer 4 TCP or UDP port number.

●

Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a

per-packet basis.

●

Four egress queues per port enable differentiated management of up to four traffic types.

●

SRR scheduling ensures differential prioritization of packet flows by intelligently servicing the

ingress and egress queues.

●

Weighted tail drop (WTD) provides congestion avoidance at the ingress and egress queues

before a disruption occurs.

●

Strict priority queuing guarantees that the highest-priority packets are serviced ahead of all

other traffic.

●

There is no performance penalty for highly granular QoS functions.

Granular Rate Limiting

●

The Cisco CIR function guarantees bandwidth in increments as small as 1 Mbps.

●

Rate limiting is provided based on source and destination IP address, source and destination

MAC address, Layer 4 TCP and UDP information, or any combination of these fields, using

QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy maps.

●

Asynchronous data flows upstream and downstream from the end station or on the uplink are

easily managed using ingress policing and egress shaping.

●

Up to 64 aggregate or individual polices are available per Fast Ethernet or Gigabit Ethernet

port.
