The dual rate, 3-ColorMarker in color-aware and color-blind modes, as defined in RFC 2698 for traffic policing, is supportedon ingress ISE/E5 interfaces to classify packets.The police command configures traffic policing using two rates, the committed information rate (CIR)and the peak information rate (PIR). The following conform, exceed, and violate values for the actionsargument are supported with the police command in policy-map configuration mode on an ISE/E5interface bound to an L2TPv3 tunnel session:• conform-action actions: Actions taken on packets that conform to the CIR and PIR.– set-prec-tunnel: Sets the IP precedence value in the tunnel header of a packet encapsulated fornative L2TPv3 tunneling.– set-dscp-tunnel: Sets the IP differentiated services code point (DSCP) value in the tunnelheader of a packet encapsulated for native L2TPv3 tunneling.– transmit: Sends the packet with no alteration.• exceed-action actions: Actions taken on packets that conform to the CIR but not the PIR.– drop: Drops the packet.– set-clp (ATM only): Sets the Cell Loss Priority (CLP) bit from 0 to 1 in an ATM cellencapsulated for native L2TPv3 tunneling.– set-dscp-tunnel: Sets the DSCP value in the tunnel header of a packet encapsulated for nativeL2TPv3 tunneling.– set-dscp-tunnel and set-clp (ATM only): Sets the DSCP value in the tunnel header and the CLPbit in an ATM cell encapsulated for native L2TPv3 tunneling.– set-dscp-tunnel and set-frde (Frame Relay only): Sets the DSCP value in the tunnel header anddiscard eligible (DE) bit in a Frame Relay packet encapsulated for native L2TPv3 tunneling.– set-frde (Frame Relay only): Sets the DE bit in a Frame Relay packet encapsulated for nativeL2TPv3 tunneling.– set-prec-tunnel and set-clp (ATM only): Sets the precedence value in the tunnel header and theCLP bit in an ATM cell encapsulated for native L2TPv3 tunneling.103
