[rbak-nsp] Basic QoS subscriber setup

[Tanan Satayapiwat]

Hi Jim,
Perhaps there are many other different ways but what I can think of is you can mark priority on all incoming ports.
policy access-list qostest
  seq 10 permit tcp host 0.0.0.0 eq www any class class-1
  seq 20 permit tcp 213.199.144.0 0.0.15.255 any class class-2
  seq 30 permit ip any any class default

Qos policy abc policing
 access-group qostest local
   class class-1
     mark priority 1

Port eth 1/1 (incoming port)
 qos policy policing abc

At least I see it work with one of my customers.

Cheers,
Tanan

Subject: [rbak-nsp] Basic QoS subscriber setup

Hi,

I'm trying to test some basic QoS on a subscriber circuit and I'm a little stuck.  I want to prioritise certain traffic types eg VOIP > IPTV  > HTTP > Other.  I have the following so far:

-----
qos policy testpq pq
 num-queues 4
 queue 0 rate 3250 burst 40000
 queue 1 rate 250 burst 40000
 queue 2 rate 250 burst 40000
 queue 3 rate 250 burst 40000

context testcontext
 policy access-list qostest
  seq 10 permit tcp host 0.0.0.0 eq www any class class-1
  seq 20 permit tcp 213.199.144.0 0.0.15.255 any class class-2
  seq 30 permit ip any any class default

 subscriber name test at blah.com
   qos policy queuing testpq
   rate circuit out 4000 burst 10
-----

How do I classify traffic into different priority queues?  I will eventually set the DSCP value before it hits the SE800 and require the SE800 to map DSCP to priority somehow, but right now I want to have the Redback use different priorities based on traffic properties such as the source or the port.  I can see how this is done with a metering profile as you can apply an access-group to that to map traffic to classes.

How do I achieve this with pq QoS as I dont want to set specific bandwidths for different traffic types as with metering/policing but use queues and priorities?  I'm sure I'm missing something obvious or got the wrong end of the stick.

Thanks.

Jim.
