Configure the logical interface encapsulation type by including the encapsulation statement:

[edit interfaces at-pim/0/port unit logical-unit-number]encapsulation type;

You can include this statement at the following hierarchy levels:

[edit interfaces interface-name unit logical-unit-number]

[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]

Table 1 shows the logical interface encapsulation types for ATM-over-ADSL interfaces.

Table 1: ATM-over-ADSL Encapsulation Types

Encapsulation Types	Comments
Physical Interface
ether-over-atm	Ethernet over ATM encapsulation. Use this type of encapsulation for interfaces that carry IPv4 traffic.
atm-pvc	ATM permanent virtual circuits (PVCs).
Logical Interface
atm-vc-mux	Use ATM VC multiplex encapsulation. You can only configure the inet family when you use this type of encapsulation.
atm-nlpd	Use ATM network layer protocol ID (NLPD) encapsulation. You can only configure the inet family when you use this type of encapsulation.
atm-cisco-nlpd	Use Cisco NLPD encapsulation. You can only configure the inet family when you use this type of encapsulation.
atm-snap	Use ATM subnetwork attachment point (SNAP) encapsulation.
atm-ppp-vc-mux	Use PPP over ATM AAL5 multiplex encapsulation.
atm-ppp-llc	Use ATM PPP over AAL5 logical link control (LLC) encapsulation.
ether-over-atm-llc	Use Ethernet over LLC encapsulation for interfaces that carry IPv4 traffic. You cannot configure multipoint interfaces if you use this type of encapsulation.
ppp-over-ether-over-atm-llc	Use PPP over Ethernet over ATM LLC encapsulation. You cannot configure the interface address when you use this encapsulation type. Instead, you configure the interface address on the PPP interface.
