srr-queue bandwidth share

This example shows how to configure the weight ratio of the SRR scheduler running on an egress port.

Four queues are used. 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 gigabitethernet0/1

Switch(config-if)# srr-queue bandwidth share 1 2 3 4

You can verify your settings by entering the show mls qos interface [interface-id] queueing privileged

EXEC command.

Catalyst 2960 Switch Command Reference

Allocates buffers to a queue-set.

Maps class of service (CoS) values to an egress queue or maps

CoS values to a queue and to a threshold ID.

Maps Differentiated Services Code Point (DSCP) values to an

egress queue or maps DSCP values to a queue and to a

threshold ID.

Configures the weighted tail-drop (WTD) thresholds,

guarantees the availability of buffers, and configures the

maximum memory allocation to a queue-set.

Enables the egress expedite queue on a port.

Maps a port to a queue-set.

Displays quality of service (QoS) information.

Assigns the shaped weights and enables bandwidth shaping on

the four egress queues mapped to a port.
