[c-nsp] QoS on Cisco 2600

[Jeff Wojciechowski]

Hi Stephanie,

Here's what we have configured:

class-map match-all citrix-all
 match protocol citrix


policy-map PPS
 class citrix-all
  set ip dscp cs3
    bandwidth 800
 class class-default
    fair-queue
  set ip dscp af21


ip nbar protocol-discovery on all interfaces

service policy output PPS on my WAN interface

(in this case we are giving Citrix 800kbps and using Fair Queuing on remainder of traffic) Not sure if this will work on a 2600.....this is running on a 3825. I think the issue will be whether or not your 2600 will do NBAR.

Then do:

Show policy map interface *wan interface* to verify packets are going thru queue - in my case:

    Class-map: citrix-all (match-all)
      55310079 packets, 4798639048 bytes
      5 minute offered rate 340000 bps, drop rate 0 bps
      Match: protocol citrix
      Queueing
      queue limit 64 packets
      (queue depth/total drops/no-buffer drops) 0/52/0
      (pkts output/bytes output) 55310028/4798625680
      QoS Set
        dscp cs3
          Packets marked 55310080
      bandwidth 800 kbps

Thanks,

-Jeff

Hi

I have a Cisco 2600, connected at 4 Mbits by a Ethernet Link at a Cisco 7204.

I want add qos for :
   Telnet (TCP 23) and Cistrix

Exemple: 1 Mbits reserved to this protocol

If citrix/telnet don't use this bandwitch, bw available for other protocole.

Anyone have a sample config ?

Thanks
STephane
