Configuration Tasks
Verifying a PVC Configuration
To verify the configuration of a particular PVC, use the show atm pvc command:
Router# show atm pvc
VCD / Peak Av/Min Burst
Interface Name VPI VCI Type Encaps SC Kbps Kbps Cells St
0/2/2.1 1 2 32 PVC SNAP UBR 149760 UP
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.
Creating a PVC on a Point-to-Point Subinterface
Use point-to-point subinterfaces to provide each pair of routers with its own subnet. When you create a
PVC on a point-to-point subinterface, the router assumes it is the only point-to-point PVC that is
configured on the subinterface, and it forwards all IP packets with a destination IP address in the same
subnet to this VC. To configure a point-to-point PVC, perform the following procedure beginning in
global configuration mode:
Command or Action Purpose
Step 1
Router(config)# interface atm
slot/subslot/port.subinterface point-to-point
Creates the specified point-to-point subinterface on the
given port on the specified ATM SPA, and enters
subinterface configuration mode, 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.
Step 2
Router(config-subif)# ip address address mask Assigns the specified IP address and subnet mask to this
subinterface.
Step 3
Router(config-subif)# pvc [name] vpi/vci 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 Routers.
