David,

Try adding this command:


ip nbar pdlm flash:citrix.pdlm


Please rate helpful posts.

This order has been entered. The router says me that my pdlm is more recent.

David,

So the PDLM is in the IOS. Your config looks correct. I have this running on 7206s, and it matches correctly on the ICA tags.


Is your Citrix implementation using port 1494 or 2598 session reliability? I do not think Citrix NBAR supports 2598, but I need to find out, because we are heading that way.


I would build an access list to check this out.


access-list 101 permit tcp any eq 1494 any

access-list 101 permit tcp any any eq 1494

access-list 101 permit tcp any eq 2598 any

access-list 101 permit tcp any any eq 2598

access-list 101 permit ip any any


Apply this inbound on your interface:


ip access-group 101 in


Then show access-list 101 and look for hits.

I have tried to do that with acl, so I saw well that I used the port 1494 in TCP, Is there one or more commands in my configuration could prevent the match nbar.

Thanks a lot for your help
