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.
Hmm, I don't recall that being the actual (basic) default for 3750 QoS. It might be a default for some variant of auto QoS.
As to why Q1 would be limited to 4%, that would likely be done if PQ is enabled too, which on a 3750 doesn't have an implicit rate limiter. I.e. PQ, but itself, could stave all your other queues of bandwidth. As to also why 4%, that just some assumption that your EF traffic would not need more than that.
I'm working on a project that includes basic router configurations. I configurated everything including: line console 0, line vty 0 15 and secret passwords. There are 3 routers in the network and every LAN is going t...
