Verifying a Multipoint PVC Configuration

To verify the configuration of a particular PVC, use the show atm pvc command:
Router# show atm pvc 1/120
ATM3/1/0.120: VCD: 1, VPI: 1, VCI: 120
UBR, PeakRate: 149760
AAL5-LLC/SNAP, etype:0x0, Flags: 0xC20, VCmode: 0x0

Purpose
Configures the PVC for a particular protocol and maps it
to a specific protocol-address.
• protocol—Typically set to ip or pppoe, but other
values are possible.
PPP is not supported on the Cisco ASR 1000
Note
Series Routers, and PPPoE is supported
beginning in Cisco IOS XE Release 2.5.
protocol-address—Destination address or virtual
•
template interface for this PVC (if appropriate for
the protocol).
inarp—Specifies that the PVC uses Inverse ARP to
•
determine its address.
broadcast— Specifies that this mapping should be
•
used for multicast packets.
(Optional) If using Inverse ARP, configures how often
the PVC transmits Inverse ARP requests to confirm its
address mapping. The valid range is 1 to 60 minutes, with
a default of 15 minutes.
(Optional) Configures the ATM adaptation layer (AAL)
and encapsulation type, where:
• aal5mux protocol—AAL and encapsulation type for
multiplex (MUX)-type VCs. A protocol must be
specified when you use this encapsulation type.
aal5nlpid—(IP only) AAL and encapsulation type
•
that allows ATM interfaces to interoperate with
High-Speed Serial Interfaces (HSSIs) that are using
an ATM data service unit (ADSU) and running
ATM-Data Exchange Interface (DXI). Supported on
ATM PVCs only.
aal5snap—AAL and encapsulation type that
•
supports Inverse Address Resolution Protocol
(ARP). Logical link control/Subnetwork Access
Protocol (LLC/SNAP) precedes the protocol
datagram. This is the default.
Exits interface configuration mode and returns to
privileged EXEC mode.
