Note that the sample output policy configured for a TSC-based L2TPv3 tunnel session in the section“Configuring QoS on a Frame Relay Interface in a TSC-Based L2TPv3 Tunnel Session” is not supportedon a Frame Relay ISE/E5 interface. QoS policies on per-DLCI output traffic are not supported on ISE/E5interfaces configured for a native L2TPv3 tunnel.policy-map oclass d2bandwidth percent 10random-detect precedence 1 200 packets 500 packets 1class d3bandwidth percent 10random-detect precedence 1 1 packets 2 packets 1!interface Serial0/1/1:0encapsulation frame-relayframe-relay interface-dlci 100 switchedclass fr-mapservice output oConfiguring Tunnel Marking in a Native L2TPv3 Tunnel SessionThe QoS: Tunnel Marking for L2TPv3 Tunnels feature allows you to set (mark) either the IP precedencevalue or the differentiated services code point (DSCP) in the header of an L2TPv3 tunneled packet, usingthe set-prec-tunnel or set-dscp-tunnel command without configuring QoS traffic policing. Tunnelmarking simplifies administrative overhead previously required to control customer bandwidth byallowing you to mark the L2TPv3 tunnel header on an ingress ISE/E5 interface.The following example shows how to configure tunnel marking using MQC set commands for the defaulttraffic class and a traffic class that matches a specified Frame Relay DE bit value:class-map match-any match-frdematch fr-depolicy-map set_prec_tunclass match-frdeset ip precedence tunnel 1class class-defaultset ip precedence tunnel 2!map-class frame-relay fr_100service-policy input set_prec_tunL2TPv3 Customer-Facing ISE/E5 Interfaceinterface POS0/0frame-relay interface-dlci 100 switchedclass fr_100Configuring Traffic Shaping in a Native L2TPv3 Tunnel SessionThe following example shows how to configure traffic shaping on a Frame Relay ISE/E5 egress interfacebound to a native L2TPv3 tunnel session. You can configure traffic shaping on a Frame Relay mainegress interface by classifying traffic with different class maps.NoteYou cannot configure per-DLCI shaping using the method shown in this example to configure trafficshaping.105
