QoS - LLQ inside GTS

Hello,

I have read articles to configure CBWFQ inside GTS, using bandwidth percent on the CBWFQ side, then putting that policy into a GTS 'shape average' policy.

I want to do exactly that, but need LLQ for voice - so use the 'priority 64' for voice, then have 'bandwidth percent' for the other classes of traffic.

Can I do that?

Re: QoS - LLQ inside GTS

Hello,

As you mentioned you can use priority for Voice & bandwidth remaining percent for other classes here's example

#################

policy-map out

class Voice-class

priority 80 10000

police 80000 10000 10000 conform-action set-dscp-transmit 46 exceed-action set-dscp-transmit 46

class data1

bandwidth remaining percent 40

random-detect dscp 26 65 195 20

random-detect dscp 28 32 64 20

class data2

random-detect dscp 18 111 222 20

random-detect dscp 20 62 124 20

random-detect dscp 10 141 282 20

random-detect dscp 12 93 186 20

hope this help
