Yes mark i can see the ports 1604 and 1494 when i did a show ip nbar port-map.sh ip nbar port-map port-map bgp                      udp 179 port-map bgp                      tcp 179 port-map citrix                   udp 1604 port-map citrix                   tcp 1494 port-map cuseeme                  udp 7648 7649 24032 port-map cuseeme                  tcp 7648 7649 port-map dhcp                     udp 67 68 port-map dns                      udp 53 port-map dns                      tcp 53sh access-lists                    Extended IP access list 103    10 permit tcp any any eq 3389    20 permit tcp any eq 3389 anyExtended IP access list 110    10 permit tcp any eq 2598 any    20 permit tcp any any eq 2598    30 permit tcp any eq 1494 any    40 permit tcp any any eq 1494 (3 matches)    50 permit tcp any eq 1604 any    60 permit tcp any any eq 1604Only three packets are matched with port 1494. When i did a "bebug ip packet 110 detail" i couldn't see any packets matching ACL 110.Is there any other commands or debug comands to check the ports for the existing traffic.ThanksRajesh

Hi,it looks to me as if your CITRIX implementation does not use the ports NBAR is looking for. Can you check the ports CITRIX is using, or whether there is any tunneling/encryption applied to CITRIX traffic. The last thing that could happen: are you sure about CITRIX or could it be MS remote desktop or other stuff?Just for testing I would specify the CITRIX server IP and not be port specific in the ACL.Regards, Martin

Thanks for your help guys..Today morning i noticed that the packets are being captured and working fine. As Martin said, thinking of discussing with the Citrix administrator to know the exact ports and to apply ACL's for better performance.Once again thanks for all your help and support.
