oamping interface

Syntax	oamping interface atm interface-number pvc { pvc-name vpi/vci } [ number
	timeout ]
View	ATM interface view
Parameter	atm interface-number: ATM interface number.
	pvc-name: PVC name, a unique string of 1 to 16 characters on ATM interface, not
	case-sensitive. The name cannot be the same as a valid VPI/VCI pair value. For
	example, the name 1/20 is not allowed.
	vpi/vci: VPI/VCI pair. VPI is short for virtual path identifier; its value ranges from 0
	to 255. VCI is short for virtual channel identifier; its value range varies by interface
	type. Normally, VCI values from 0 to 31 are reserved for special purpose, you are
	not recommended to use them. For details regarding the value range, refer to
	Table 28.
	number: Number of OAM cells to be transmitted consecutively, in the range 1 to
	1,000. The system default is 5.
	timeout: OAM response timeout period in seconds, in the range 1 to 30. The
	system default is 2.
Description	Use the oamping interface command to send OAM cells over the specified PVC
	on the specified ATM interface so as to check the link state. If no response is
	received within the specified time, this means that the link is bad, or too busy that
	packets are lost.
Example	# Check the link state of PVC 1/32 on ATM interface 1/0, sending three cells and
	setting timeout period to one second.
