All- I am pretty new at using NBAR - does the config below ensure that traffic in each direction (TCP 1494 from client to server *AND* the random TCP port between server to client) gets prioritized?
I have the same class map "match protocol citrix" configured on each of my WAN routers (all running 12.4-22.T3). So I guess the question boils down to "what does NBAR specifically use to classify traffic such as Citrix"? Naturally the goal is to ensure that *ALL* Citrix traffic is given priority since we don't do any mapped drives/printing directly to our thin clients.

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 This electronic mail (including any attachments) may contain information that is privileged, confidential, or otherwise protected from disclosure to anyone other than its intended recipient(s).
