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 gigabitethernet2/0/1
Switch(config-if)# srr-queue bandwidth share 1 2 3 4
This example shows how to enable the egress expedite queue when the SRR weights are configured. The
egress expedite queue overrides the configured SRR weights.
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# srr-queue bandwidth shape 25 0 0 0
Switch(config-if)# srr-queue bandwidth share 30 20 25 25
Switch(config-if)#
priority-queue out
Switch(config-if)# end
This example shows how to limit the bandwidth on a port to 80 percent:
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# srr-queue bandwidth limit 80
When you configure this command to 80 percent, the port is idle 20 percent of the time. The line rate drops
to 80 percent of the connected speed, which is 800 Mb/s. These values are not exact because the hardware
adjusts the line rate in increments of six.
