[FrogOnDSCP46EF]

Hello all,

I have a customer who are using frame-relay link for voip and data. Sometime
the link gets congested and the customer has asked us to mask the total
usage based on the link utilization.

the link bandwidht is a E1 - 2048 mpbs.
link type ; frame-relay/FRTS
Required; if total traffic in the link goes above 80% , it should mark all
access packets to AF31.

i am thinking to put the below configuration on cisco 2811 routers.

current config;

class-map signaling
 match dscp cs3
 match dscp af31

class-map RTP
 match dscp ef

policy-map To-remote-office
 class signaling
  bandwidth 128 kbps
class RTP
 priority 800 kbps
class class-default
 fair-queue

here is what i have plan..

1. create another policy and stack existing 'to-=remote-office' policy to
new policy.

policy-map 80percentmarkdown
 service-policy output To-Remote-Office
class class-default
 police 1600kbps transmit, exceed-action set-dscp af31   <----------------
1600kbps = 80% of the total link

map-class frame-relay to-remote-site
 service-policy output 80percentmarkdown


What is the best way to match the all traffic and mark above 80% of total
traffic to AF31?
Where shell i apply that?



thanks
