Configuring the SRR Scheduler: Example
This example shows how to configure the weight ratio of the SRR scheduler running on an egress port.
Four queues are used, and the bandwidth ratio allocated for each queue in shared mode is 1/(1+2+3+4),
2/(1+2+3+4), 3/(1+2+3+4), and 4/(1+2+3+4), which is 10
percent, 20 percent, 30 percent, and 40
percent for queues 1, 2, 3, and 4. This means that queue 4 has four times the bandwidth of queue 1, twice
the bandwidth of queue 2, and one-and-a-third times the bandwidth of queue 3.
Switch(config)# interface gigabitethernet1/1
Switch(config-if)# srr-queue bandwidth share 1 2 3 4
show mls qos Displays global QoS configuration information.
show mls qos aggregate-policer
[aggregate-policer-name]
Displays the aggregate policer configuration.
show mls qos input-queue Displays QoS settings for the ingress queues.
show mls qos interface [interface-id] [buffers |
policers | queueing | statistics]
Displays QoS information at the port level, including the buffer
allocation, which ports have configured policers, the queueing strategy,
and the ingress and egress statistics.
show mls qos maps [cos-dscp | cos-input-q |
cos-output-q | dscp-cos | dscp-input-q |
dscp-mutation dscp-mutation-name |
dscp-output-q | ip-prec-dscp | policed-dscp]
Displays QoS mapping information.
The DSCP input queue threshold map appears as a matrix. The d1 column
specifies the most-significant digit of the DSCP number; the d2 row
specifies the least-significant digit in the DSCP number. The intersection
of the d1 and the d2 values provides the queue ID and threshold ID; for
example, queue 2 and threshold 1 (02-01).
The CoS input queue threshold map shows the CoS value in the top row
and the corresponding queue ID and threshold ID in the second row; for
example, queue 2 and threshold 2 (2-2).
show mls qos maps dscp-to-cos Verifies your entries.
show mls qos queue-set [qset-id] Displays QoS settings for the egress queues.
show mls qos vlan vlan-id Displays the policy maps attached to the specified SVI.
show policy-map [policy-map-name [class
class-map-name]]
Displays QoS policy maps, which define classification criteria for
incoming traffic.
Note Do not use the show policy-map interface privileged EXEC
command to display classification information for incoming
traffic. The control-plane and interface keywords are not
supported, and the statistics shown in the display should be
ignored.
show running-config | include rewrite Displays the DSCP transparency setting.
