Chapter 7 Configuring the ATM SPAs
Configuration Tasks
Tip To verify the configuration and current status of all PVCs on a particular interface, you can also use the
show atm vc interface atm command.
Note 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 XE software assumes that you want to modify that PVC’s configuration and
automatically switches to its parent subinterface.
Step 4
Router(config-if-atm-vc)# protocol protocol
protocol-address [[no]
broadcast]
Configures the PVC for a particular protocol and maps it to
a specific protocol-address.
• protocol—Typically set to ip or pppoe for
point-to-point subinterfaces, 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 (as appropriate for the
specified protocol).
• [no] broadcast—(Optional) Specifies that this
mapping should (or should not) be used for broadcast
packets.
The protocol command also has an inarp option, but this
option is not meaningful on point-to-point PVCs that use a
manually configured address.
Step 5
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 5 for each point-to-point subinterface to be configured on this ATM SPA.
Step 6
Router(config-if)# end Exits interface configuration mode and returns to privileged
EXEC mode.
