SRR can be configured for Sharing or for Shaping on Egress whereas, Sharing
is the only solution available on Ingress queues. When configuring the
Queues for Shaping, you should remember that the configured Queue is
RATE-LIMITED to the configured amount. This means that even if nothing else
is going on, you will ONLY get the configured rate and that all.
When Sharing is configured always think of CBWFQ, which means that the
minimum amount of bandwidth is what you are configuring, which means that if
nothing else is going on you can use more bandwidth than the configured
value.
If you have configured "srr-queue bandwidth share 10 10 30 50, then Q1 is
getting 10 percent, Q2 is also getting 10 percent, Q3 is getting 30 percent
and the forth Q is getting 50 percent. Which means that Q4 is getting 5
times the bandwidth of Q1 or Q2.
Always remember that Shape will override the Share.
I hope that helps.
