Cisco Cisco IOS Software Release 12.0(21)S

To perform an ATM Operation Administration Maintenance (OAM) ping on a specific permanent virtual 
circuit (PVC), use the ping atm interface atm command in privileged EXEC mode.

ping atm interface atm interface-number vpi-value vci-value [end-loopback [repeat [timeout]] | 

seg-loopback [repeat [timeout]]] 

End loopback
Repeats: 5
Timeout interval: 2 seconds

Privileged EXEC

The ping atm interface atm command sends an OAM packet and indicates when a response is received. 
It can be used either in normal mode or in interactive mode. The ping atm interface atm command 
provides two ATM OAM ping options:

End loopback—Verifies end-to-end PVC integrity.

Segment loopback—Verifies PVC integrity to the neighboring ATM device.

In the following example, an ATM OAM ping with a 15-second timeout verifies end-to-end connectivity 
for PVC 0/500 in the normal mode:

atm interface_number

ATM interface name.

Virtual path identifier. Range: 0 to 255.

Virtual channel identifier. Range: 0 to 65535.

(Optional) Send ATM end loopback cells. This is the default.

(Optional) Send ATM segment loopback cells.

(Optional) Number of ping packets that are sent to the destination address. 
Range: 1 to 1000. Default: 5.

(Optional) Timeout interval, in seconds. Range: 1 to 30. Default: 2.
