Granular Rate Limiting
● The Cisco Committed Information Rate (CIR) function guarantees bandwidth in increments as low as 8 kbps.
● 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 policers are available per Fast Ethernet or Gigabit Ethernet port
