srr-queue bandwidth share
Examples
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.
