Hi can anyone help, I am trying to set up NBAR to prioritize Citrix traffic using the ICA tags in the Citrix frame header. But I cannot get it to work.
We are using version 6 PDLM, IOS 12.3(4)T on a 7206 when we check the policy map stats there are no matches, we have also sniffed the citrix traffic to check that it is being marked. The configuration is as follows (the gig0/3 interface is the main interface of a 802.1q VLAN trunk i.e. the traffic we want to mark is coming in over the sub interfaces)
class-map match-all Citrix-medium
match protocol citrix ica-tag "1"
class-map match-all Citrix-high
match protocol citrix ica-tag "0"
class-map match-all Citrix-background
match protocol citrix ica-tag "3"
class-map match-all Citrix-low
match protocol citrix ica-tag "2"
policy-map ABCCITRIX
class Citrix-high
set dscp ef
class Citrix-medium
set dscp 11
class Citrix-low
set dscp 11
class Citrix-background
set dscp 11
class test
set dscp af43
interface GigabitEthernet0/3
no ip address
ip nbar protocol-discovery
service-policy input ABCCITRIX
duplex auto
speed auto
media-type rj45
no negotiation auto
