15. Test Commands

OPR-LPBK-VCL

The OPR-LPBK-VCL command places a specific Virtual Channel Link (VCL) in loopback mode.

Table 15-3. OPR-LPBK-VCL Command Parameters

OPR-LPBK-VCL:[tid]:aid_vcl:[ctag]:[locn],[orgn] [lpbktype];

RESTRICTIONS:

TAll parameters in this command are position-defined. Only one loopback at a time is allowed on a facility.

[tid]	Identification of the target NE. The default value is null. The NE SID
	code is the only other valid value.
aid_vcl	Virtual channel identifier for OAM loopbacks. The value can be
	preceded with AID=, but this is not required. Grouping and ranging are
	allowed. Enter in the following format, replacing lower-case parameters
	with the values given:
	NTVCL-vpi-vci: VCL for NT circuit
	LTVCL-rack-shelf-slot-circuit-vpi-vci: VCL for LT circuit
	– rack: rack number (1)
	– shelf: shelf number (1)
	– slot: LT slot number (1)
	– circuit: ADSL circuit on the LT (1− 24)
	– vpi: Virtual Path Identifier
	– vci: Virtual Channel Identifier
	– segment: ATM location identifier. A 32-character hexadecimal
	field that identifies the intermediate point responsible for looping
	back F5 OAM segment loopback cells. If absent, the loopback is
	performed at the end of the segment connection. Not accepted for
	lpbktype E2E. Optional for lpbktype SEG.
[locn]	Facility location. Valid values are:
	FEND (far end): This is the default.
	FEND_segment
[orgn]	Source of the signal to be looped back. The only valid value is NEND
	(near end).
[ctag]	Correlation tag (6 characters maximum) that links an input command
	with associated output responses. The default is 0.
[lpbktype]	Loopback type. Valid values are:
	E2E: End-to-End loopback. Identifies an OAM loopback test on a VCL
	or VCC termination point using an end-to-end OAM cell.
	SEG: Segment loopback. Identifies an OAM loopback test on a VCL or
	VCC termination point using a segment OAM cell (default).
