Matching the Frame Relay DE Bit Configuration Example
The following example shows how to configure the service policy called match-de and attach it to an
interface. In this example, the class map called data evaluates all packets entering the interface for a DE
bit setting of 1. If the entering packet has been a DE bit value of 1, the packet’s EXP bit setting is set to 3.

Configuring the Xconnect Attachment Circuit for ATM VP Mode Single Cell
Relay over L2TPv3 Example
The following configuration binds a PVP to an Xconnect attachment circuit to forward ATM cells over
an established L2TPv3 pseudowire:
pw-class atm-xconnect
encapsulation l2tpv3
interface ATM 4/1
atm pvp 5 l2transport
