HI
I am wandering if I need to remap the default COS - DSCP map on the cat 6500 and what the priority queue is.
Do i need to run these commands on the CAToS switches. I understand that I only need to mark at the access. ONce successfully marksed I will be trusting COS thoughout the network on all uplinks to the dsitribution and to the voice switch.
set qos cos-dscp-map 0 8 16 24 32 46 48 56
set qos ipprec-dscp-map 0 8 16 24 32 46 48 56
set qos dscp-cos-map 0-7:0 8-15:1 16-23:2 24-31:3 32-39:4 40-47:5 48-55:6 56-63:7
The setup for the site is
IP Handsets --> Floor Access Switch --> Distribution Switch -- Voice switch -- CCM and Voice gateways
Floor Access switch (CAToS)
WS-C6509-E
WS-SUP32-10GE-3B
WS-X6148-GE-45AF
Distribution switch (IOS)
WS-C6509-E
WS-SUP720-3B
WS-X6708-10G-3C
Voice switch (CAToS)
WS-C6506-E
WS-SUP32-10GE-3B
WS-X6148A-GE-TX
Is it a good idea to run these to put the values into the correct queues and thresholds.
Set qos map 1p1q4t rx 1 1 cos 0
Set qos map 1p1q4t rx 1 2 cos 2-3
Set qos map 1p1q4t rx 1 3 cos 4
set qos map 1p1q4t rx 2 1 cos 5
set qos map 1p1q4t rx 1 4 cos 6-7
set qos drop-threshold 1p1q4t rx queue 1 50 60 80 100
Set qos map 1p2q2t tx 1 1 cos 0-1
Set qos map 1p2q2t tx 1 2 cos 2
Set qos map 1p2q2t tx 2 1 cos 3-4
set qos map 1p2q2t tx 3 1 cos 5
set qos map 1p2q2t tx 2 2 cos 6-7
set qos wred 1p2q2t tx queue 1 70:100 70:100
set qos wred 1p2q2t tx queue 2 70:90 100:100
set qos wrr 1p2q2t 50 255
set qos txq-ratio 1p2q2t 70 15 15
Thanks
Paul
