LCN parameter

Use the logical channel numbers (LCN) parameter to select the NPSI, XI, and PVI elements for the X.25 line trace report.

Use the LINENODE parameter to select physical lines by specifying their names. If you do not specify LINENODE, ACF/TAP tests the NODE parameter. For more information, see NODE parameter.

ALL
This is the default if a value is not specified or the parameter is reset. All the logical channel numbers (LCNs) in the trace data are selected in the sequence encountered. Use this value to select supervisory and unnumbered frames.
nnn
Specify this value to determine the 3-digit logical channel addresses that are shown in the line trace report, sorted by LCN. Up to 10 logical channel addresses can be specified. However, system performance degrades with each additional logical channel address specified.
