Hello, I was looking for clarification on the following items all related to EGRESS queuing on 3750 switch. Thank you.
If a packet is received with BOTH COS and DSCP markings which QOS label is used as a basis for selection of the egress queue and threshold….COS or DSCP?How can I control this?I have read it is based on the trust setting of the port which is confusing as trust is ingress not egress.
On egress, should the“mls qos maps cos−output−q” and “mls qos maps DSCP−output−q” be consistent?The documentation indicates this should be the case on ingress, see below.However there is no mention of this for egress queues?
“Therefore, the Dscp−inputq−threshold map is configured to sync with the Cos−inputq−threshold map. These mappings should be as consistent as possible in order to ensure predictable behavior and to simplify troubleshooting.”
Sharing Ration Calculation.I am a little unsure of the math here.On egress if I am using both shapingand sharing and I want to shape queue 1 to 25%and insure queue 2 is given a minimum of 30% during periods of congestion do the below configurations both accomplish this.
