Configuration Tasks
Step 5
Router(config-if-atm-vc)# protocol protocol
{protocol-address | inarp} [[no]
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
interface template for this PVC (if appropriate for the
protocol).
• inarp—Specifies that the PVC uses Inverse ARP to
determine its address.
• [no] broadcast—(Optional) Specifies that this
mapping should (or should not) be used for broadcast
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.
Possible values for the protocol argument are as
follows:
• aal5nlpid—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.
Step 8
Router(config-if-atm-vc)# tx-limit buffers (Optional) Specifies the number of transmit buffers for this
VC. The valid range is from 1 to 57343, with a default value
that is based on the current VC line rate and on the latency
value that is configured with the atm tx-latency command.
Note Repeat Step 4 through Step 7 for each PVC to be configured on this interface.
Step 9
Router(config-if-atm-vc)# end Exits ATM VC configuration mode and returns to
privileged EXEC mode.
