Configure one of the following:
Configuring Logical Interface Properties
To configure logical interface properties, include the
statement, and
You can include these statements at the following hierarchy levels:
To configure the logical link-layer encapsulation type, include the
statement.
ATM-over-SHDSL interfaces that use
encapsulations on the logical interface:
ATM-over-SHDSL for PPP over ATM interfaces support the following encapsulations
on the logical interface:
ATM-over-SHDSL interfaces also support the following encapsulations on the logical
interface:
encapsulation (atm-pvc | ether-over-atm);
—ATM permanent virtual circuits (PVCs), used for PPP over ATM over
atm-pvc
SHDSL interfaces. This is the default encapsulation.
ether-over-atm —Ethernet over ATM encapsulation. For interfaces that carry IPv4
traffic, use this type of encapsulation.

atm-vc-mux —Use ATM VC multiplex encapsulation. You can only configure the
family when you use this type of encapsulation.
inet
atm-nlpd —Use ATM network layer protocol ID (NLPD) encapsulation. You can
only configure the family when you use this type of encapsulation.
inet
atm-cisco-nlpd —Use Cisco NLPD encapsulation. You can only configure the
family when you use this type of encapsulation.
—Use ATM PPP over AAL5 logical link control (LLC) encapsulation.
atm-ppp-llc
—Use PPP over ATM AAL5 multiplex encapsulation.
