Trying to understand this a little better. Cisco's documentation is
not written in very clear english. Very frustrating trying to
understand the threshold values as well as the shape versus share
bandwidth values.
QOS.
Cos 5 for queue 1
queue 2
queue 3
queue 4 0
similar to lab 2 .
Queue one has the 25% of the bandwidth. other bandwidth is shared as
30 40 30.
If the queue 2 is saturated by 60% then the cos 4 has to be dropped.
Here is what I think it is. Can someone please correct me if i am
wrong and provide any positive feedback.
!
mls qos srr-queue output cos-map queue 2 threshold 2 4 !maps
cos 4 to queue 2 and threshold 2
mls qos srr-queue output cos-map queue 4 threshold 1 0 !maps
cos 0 to queue 4
mls qos queue-set output 1 threshold 2 40 60 100 200 ! when queue
2 threshold 2 exceeds 60% cos packets with cos 4 will be dropped
