Purpose
Enters subinterface configuration mode pertaining to the specified port on the ATM
SPA, where:
• slot —Specifies the chassis slot number in the Cisco ASR 1000 Series Router
where the SIP is installed.
• subslot —Specifies the secondary slot of the SIP where the SPA is installed.
• port —Specifies the number of the individual interface port on a SPA.
• subinterface —Specifies the number of the subinterface.
Assigns the specified IP address and subnet mask to the interface or subinterface.
(Optional) Configures the default transmit latency for VCs on this ATM SPA interface.
The valid range for milliseconds is from 1 to 200, with a default of 100 milliseconds.
Configures a new ATM PVC by assigning its VPI/VCI numbers and enters ATM VC
configuration mode. The valid values for vpi /vci are:
• name —(Optional) An arbitrary string that identifies this PVC.
• vpi —Specifies the 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.
