Required Configuration Tasks
To perform the basic configuration on each subinterface, use the following procedure beginning in global
configuration mode:
SUMMARY STEPS
1.
Router(config)# interface atm slot/subslot/port.sub-interface [point-to-point | multipoint]
2.
Router(config-subif)# ip address address mask [secondary]
3.
Router(config-if)# pvc [name ] vpi /vci
4.
Router(config-subif)# description string
5.
Router(config-subif)# no shutdown
6.
Repeat Step 1 through Step 5for each ATM SPA subinterface to be configured.
7.
Router(config-subif)# end
DETAILED STEPS
PurposeCommand or Action
Enters subinterface configuration mode pertaining to the specified subinterface,
where:
Router(config)# interface atm
slot/subslot/port.sub-interface
[point-to-point | multipoint]
Step 1
• point-to-point—(Optional) Specifies a point-to-point subinterface for a
single PVC configuration.
• multipoint—(Optional) Specifies a multipoint subinterface to support
PVCs for multiple routers.
Assigns the specified IP address and subnet mask to the interface. Repeat the
command with the optional secondary keyword to assign additional, secondary
IP addresses to the port.
Router(config-subif)# ip address
address mask [secondary]
Step 2
Configures a new ATM PVC by assigning its VPI/VCI numbers and enters ATM
VC configuration mode. The valid values for vpi /vci are:
Router(config-if)# pvc [name ] vpi /vci
Step 3
• name —(Optional) An arbitrary string that identifies this PVC.
• vpi —Specifies the virtual path identifier (VPI) ID. The valid range is 0 to
255.
• vci —Specifies the VCI ID. The valid range is 32 to 65535. Values 1 to
31 are reserved and should not be used, except for 5 for the QSAAL PVC
and 16 for the ILMI PVC. ILMI is unsupported on the Cisco ASR 1000
Series Aggregation Services Routers.
