I think the solution is using policing like the configuration below:
policy-map LLQ class RTP priority 96 class SIG bandwidth 8 class class-default fair-queue police cir percent 60 conform-action transmit exceed-action set-dscp-transmit 0 Regards Christian Narvaez M. UC System Engineer Cisco CCNP+CCVP Certified MAGENTA CHILE Reyes Lavalle #3350, Las Condes +(562)2408207 +(569)78076423 De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] En nombre de Ryan Hicks Enviado el: 05 October 2008 14:10 Para: ccie_voice@onlinestudylist.com Asunto: [OSL | CCIE_Voice] QoS Question class-default? QoS - Question. After setting up a policy to macth RTP and signalling in a LLQ policy in which I used 96k for rtp and 8k for SIG across the WAN. The PVC is 384k. What if another question was asked to make sure that the remaining traffic's dscp marking must be maintained if the pvc is utilized under 60%. If the remaining traffic's utilization goes over 60% of the pvc speed then set the dscp to 0. Any ideas? I am assuming it be would be reffering to the class class-default. But I am not sure when this would be enaged when traffic is flowing through the WAN port. So I guess I need a better understanding of how what takes place and how I could configure it from the question abouve. class-map match-any RTP match ip dscp ef class-map match-any SIG match ip dscp cs3 match ip dscp af31 ! policy-map LLQ class RTP priority 96 class SIG bandwidth 8 class class-default fair-queue set ip dscp 0 ! int s0/0 bandwidth 384 service-policy out LLQ ------------------------- Ryan Hicks
