How to mark traffic coming in and out of CUE ?
class-map match-all SipControl
match protocol sip
!
policy-map SipMark
class SipControl
set ip dscp cs3
class class-default
interface Service-Engine0/0
ip unnumbered FastEthernet0/0
ip route-cache flow ——————————This command was used solely for the purpose of Netflow. Nothing to do w/marking
service-module ip address 10.1.11.5 255.255.255.0
service-module ip default-gateway 10.1.11.4
service-policy input SipMark ——————– This policy map marks packets from CUE to CME (thats why its applied inbound). Thanks to Ted for correcting this. I had applied this service policy outbound in my earlier post
dial-peer voice 20000 voip
destination-pattern 3600
session protocol sipv2
session target ipv4:10.1.11.5
dtmf-relay sip-notify
codec g711ulaw
ip qos dscp cs3 signaling — This marks SIP control packets going from CME to CUE.

10.1.11.5 is CUE, 10.1.11.4 is CME. Port 13C4 in hex translates to 5060. THis is the port on which SIP protocol listens for control packets.

This should be INBOUND not outbound, treat the Int Service-Engine just like any other interface… and these commands are taken from the ROUTERs perpective, you want to mark packet from CUE towards CME then you’re coming INTO the router just as if you were coming in from a remote network.

Ted you are right. I have verified this using Acls and debugs. Thank you!
I am not able to apply the policy map for input.

CBWFQ : Can be enabled as an output feature only

can you please tell me how to match outbound traffics which are coming from cue to cucm through switch. I need the lan qos configuration for that.
