[j-nsp] drop-profile ERX

[Vikas Sharma]

Hi,

I have one question of WRED.



We have implemented discard-class in cisco implementation for wred. We have
5 classes and different discard-class (0- 7) are attached to it. Based on
the discard-class, we drop the packet on interface going to core. In ERX,
drop-profile is the way to implement the wred.



host1(config)#drop-profile wredColored

host1(config-drop-profile)#committed-threshold percent 30 90 3

host1(config-drop-profile)#conformed-threshold percent 25 90 5

host1(config-drop-profile)#exceeded-threshold percent 20 90 10



how can I map discard-class to drop-profile?



fyi Cisco implementation  ->



policy-map SAR_QOS_1GB_TO_CR

class Premium-To-CR

   priority

   police cir percent 60 1 ms

class Business-To-CR

    bandwidth remaining percent 60

  random-detect discard-class-based

  random-detect discard-class 3 100 packets 300 packets 1

  random-detect discard-class 2 167 packets 500 packets 1

  random-detect discard-class 1 233 packets 700 packets 1

class Routing-Management-To-CR

    bandwidth remaining percent 5

    random-detect discard-class-based

     queue-limit 833 packets

class Default-To-CR

    bandwidth remaining percent 15

    random-detect discard-class-based

    random-detect discard-class 0 67 packets 200 packets 1

class Multicast-To-CR

    bandwidth remaining percent 20

    random-detect discard-class-based

    queue-limit 133
