If I want to see what parameters NBAR uses to classify traffic into a specific application, i used to use show ip nbar port-map. It was looking something like this:

Router# show ip nbar port-map dhcp

port-map    dhcp       udp    67      68
port-map    dhcp       tcp    67      68

But if i issue the command now, i get that his command is deprecated:

router#show ip nbar port-map citrix
This CLI is deprecated 

There is a bug entry, but no solution to this: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCug39332/?rfs=iqvred

Is there a command that replaces this one? I want to make sure that NBAR really uses the correct ports to recognize an application.

    NBAR uses a lot more than port numbers, which could be done with ACLs, and, in many cases, has nothing to do with port numbers.
