Cisco MWR 2941 Router Command Reference, Release 15.0(1)MR
This is the designed behavior. We recommend that you configure only L2TPv3 (or GRE) tunnel marking
and reconfigure any peers configured with the ip tos command to use L2TPv3 (or GRE) tunnel marking.
Note
For Cisco IOS Release 12.4(15)T2, marking GRE-tunneled packets is supported only on platforms
equipped with a Cisco RPM-XF.
Examples
The following example shows the set ip dscp tunnel command used in a tunnel marking configuration.
In this example, a class map called "class-cl" has been configured to match traffic on the basis of the
Frame Relay discard eligible (DE) bit setting. Also, a policy map called "policy1" has been created
within which the set ip dscp tunnel command has been configured.
Router> enable
Router# configure terminal
Router(config)# class-map class-c1
Router(config-cmap)# match fr-de
Router(config-cmap)# exit
Router(config)# policy-map policy1
Router(config-pmap)# class tunnel
Router(config-pmap-c)# set ip dscp tunnel 5
Router(config-pmap-c)# end
You must still attach a policy map to an interface or ATM PVC using the service-policy command.
Note
Policy maps with this tunnel marking are not accepted in the output direction. For more information
about attaching a policy map to an interface or ATM PVC, see the "Applying QoS Features Using the
MQC" module of the Cisco IOS Quality of Service Solutions Configuration Guide.
