Hello, I see that by default, a 3750 switch only allocates 4% of output bandwidth for queue 1 i.e. EF traffic (see attached image).
I am just interested as to why this percentage is so low compared to the other 3 queues which have 25%.
Default Scheduler Configuration:
The priority queue is disabled. Both the shaped and shared mode are configured for the SRR. Shaped mode weights override the shared mode value. Therefore, the net result is queue 1 is serviced in shaped mode and queues 2, 3, and 4 are serviced in shared mode. This means queue 1 is serviced with an absolute value that is (1/25) percent, or four percent, of the bandwidth. Queues 2, 3 and 4 are serviced at 25 percent of the bandwidth. If the bandwidth is available, then queues 2, 3 and 4 can be serviced at more than 25 percent of the bandwidth.
