QoS config 3560 - proof read please!

Unanswered Question
Sep 2nd, 2009

Hi All,

I am currently running through some QoS configs and trying to standardise them. the main one in use here on both 3750's and 3560's is:

mls qos map policed-dscp 0 24 to 8

mls qos map cos-dscp 0 8 16 24 32 46 48 56

mls qos srr-queue output cos-map queue 1 threshold 3 5

mls qos srr-queue output cos-map queue 2 threshold 1 2 4

mls qos srr-queue output cos-map queue 2 threshold 2 3

mls qos srr-queue output cos-map queue 2 threshold 3 6 7

mls qos srr-queue output cos-map queue 3 threshold 3 0

mls qos srr-queue output cos-map queue 4 threshold 3 1

mls qos srr-queue output dscp-map queue 1 threshold 3 46

mls qos srr-queue output dscp-map queue 2 threshold 1 16 18 20 22 25 32 34 36

mls qos srr-queue output dscp-map queue 2 threshold 1 38

mls qos srr-queue output dscp-map queue 2 threshold 2 24 26

mls qos srr-queue output dscp-map queue 2 threshold 3 48 56

mls qos srr-queue output dscp-map queue 3 threshold 3 0

mls qos srr-queue output dscp-map queue 4 threshold 1 8

mls qos srr-queue output dscp-map queue 4 threshold 3 10 12 14

mls qos queue-set output 1 threshold 2 70 80 100 100

mls qos queue-set output 1 threshold 4 40 100 100 100

mls qos

Interface gi0/x

srr-queue bandwidth share 1 70 25 5

srr-queue bandwidth shape 3 0 0 0

priority-queue out

mls qos trust dscp

This looks reasonable to me, the switchports connect Ericsson IP phones. Should i be worried about setting ingress thresholds etc?

Any adive much appreciated,

Cheers

Hi

5000 phones over 300 sites, same as our standard config almost.

Will be fine I say.

Though I did always wonder what would happen if i tried to upload an image from a powerquest server to my pc whilst on the phone... not tried it yet ;-)

Cheers

Matt

Hi Matt,

Thanks for the response. I am pretty happy that'll it'll work if we need it too! We have a number of different configs running all over the shop and i really want to start standardising them, so hopefully, this'll do for now.

Cheers
