Configuration Tasks
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
Step 5
Router(config-if-atm-vc)# protocol protocol
{protocol-address | inarp} broadcast
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.
Note PPP is not supported on the Cisco ASR 1000
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.
Step 6
Router(config-if-atm-vc)# inarp minutes (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.
Step 7
Router(config-if-atm-vc)# encapsulation {aal5mux
protocol | aal5nlpid| aal5snap}
(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.
Note Repeat Step 1 through Step 7 for each multipoint subinterface to be configured on this ATM SPA.
Step 8
Router(config-if-atm-vc)# end Exits interface configuration mode and returns to
privileged EXEC mode.
