IBM SC30-3681-08 manual Off Stops packet tracing on all VCCs, Syntax Wrap, Start

ATM Interface Monitoring Commands (Talk 5)

list Displays the current packet tracing options on the ATM interface.

Example:

ATM Interface+ trace
on off list []? list
Packet trace is ON
Range of VPIs to be traced:	0	-	0
Range of VCIs to be traced:	32	-	39

on Starts packet tracing on all active VCCs within the speci®ed VPI/VCI range.

Example:

ATM Interface+ trace on beginning of VPI range [0]? end of VPI range [0]? beginning of VCI range [32]? end of VCI range [65535]? 39

off Stops packet tracing on all VCCs.

Example:

ATM Interface+ trace off

ATM Interface+ trace list

Packet trace is OFF

Wrap

Use the wrap command to perform a loopback data test on the ATM interface of the adapter. Wrap can be issued on a per VC basis by specifying VPI-VCI pairs. Data is looped back internally.

You can selectively start a wrap, stop a wrap, or display the current wrap settings.

If you stop or display a wrap, the following statistics will be displayed:

vWrap transmits

vWrap receives

vWrap transmit errors

vWrap receive errors

vWrap receive timeouts

For display, the current wrap statistics are displayed.

For stop, the ®nal wrap statistics are displayed.

Syntax:
wrap	display
	start
	stop

display

Displays the current wrap settings.

start Starts the wrap procedure and speci®es the VPI-VCI length of pattern and the pattern itself.

Example:

ATM Interface+ wrap start VPI [0]?

VCI [32]?

wrap pattern length [32]?

Enter 32-byte wrap pattern: [ABCDEFGHIJKLMNOPQRSTUVWXYZ123456]?
