What is SRR-queue bandwidth shape?
“Shaped or Shared bandwidth weights can be assigned to a queue via the srr-queue bandwidth shape and srr-queue bandwidth share interface commands. Shaped mode weights override shared mode weights and use an inverse ratio (1/weight) to determine the shaping bandwidth for the queue.
What is SRR-queue bandwidth limit?
srr-queue bandwidth limit 20. Interface sending rate is limited to 2Mbps. Queue 1 is shaped to 1/50 of 10Mps, which is 200Kbps of bandwidth. The remaining bandwidth 2000-200=1800Kbps is divided equally among other queues in proportion 20:20:20=1:1:1.
How do I display QOS on a Cisco switch?
Verifying QoS Configuration on a Cisco Catalyst 3750 Series Switch
- enable.
- show running-config class-map.
- show running-config policy-map.
- show policy-map interface.
- show mls qos maps.

- show mls qos interface queuing.
- show platform port-asic stats drop statistics.
What is MLS QOS trust cos?
The mls qos trust dscp and mls qos trust cos configuration options configure the switch to trust all ingress traffic, regardless. To trust only particular traffic on ingress, use traffic classes. Traffic classes apply ACLs to specific QoS functions, such as classification, marking, and policing.
What is MLS QOS Trust Device Cisco phone?
Sets the priority of data traffic received from the IP Phone access port. The trust argument configures the IP Phone access port to trust the priority received from the PC or attached device. NOTE: The mls qos trust extend command is only valid on the 6500 series switch.
What is SRR QoS?
Shaped round robin (SRR) supports shaped mode and shared mode with shared mode being the default. Shaped mode allows individual queues to be limited (shaped), but is only available on the egress queues. Shared SRR allows non-idle lower priority traffic queues to use the idle bandwidth of higher priority queues.
What is MLS QoS command?
mls qos cos. To define the default multilayer switching (MLS) class of service (CoS) value of a port or to assign the default CoS value to all incoming packets on the port, use the mlsqoscos command in interface configuration mode.
What is MLS Cisco?
MLS provides high-performance Layer 3 switching for Cisco routers and switches. MLS switches IP data packets between subnets using advanced application-specific integrated circuit (ASIC) switching hardware.
What is priority queue data structure?
A priority queue is a special type of queue in which each element is associated with a priority value. And, elements are served on the basis of their priority. That is, higher priority elements are served first. However, if elements with the same priority occur, they are served according to their order in the queue.
