Cisco ASR 1000 Series Software Configuration Guide

PurposeCommand or Action
When using the pvc command, remember that the vpi /vci combination forms
a unique identifier for the interface and all of its subinterfaces. If you specify
a vpi /vci combination that has been used on another subinterface, the Cisco
IOS software assumes that you want to modify that PVC’s configuration and
automatically switches to its parent subinterface.
Note
Configures the PVC for a particular protocol and maps it to a specific protocol-address
.
Router(config-if-atm-vc)#
protocol protocol
Step 5
{protocol-address | inarp} [[no]
broadcast]
• protocol —Typically set to ip or pppoe, but other values are possible.
PPP is not supported on the Cisco ASR 1000 Series Aggregation Services
Routers, and PPPoE is supported beginning in Cisco IOS XE Release 2.5.
Note
• 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.
(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.
Router(config-if-atm-vc)# inarp
minutes
Step 6
(Optional) Configures the ATM adaptation layer (AAL) and encapsulation type, where:Router(config-if-atm-vc)#
encapsulation {aal5mux
protocol | aal5nlpid| aal5snap}
Step 7
• 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.
(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.
Router(config-if-atm-vc)#
tx-limit buffers
Step 8
Exits ATM VC configuration mode and returns to privileged EXEC mode.Router(config-if-atm-vc)# end
