Data Analyzer Overview
The pcapture program can monitor all traffic on a particular X.25 link,
or it ca n selectively monitor only traffic belonging to certain Virtual
Circuits (VCs) on a link. The VCs of interest are identified by their
Logical Channel Number (LCN); up to six filter LCNs may be specified
for each X.25 analyzer session. By using this filter option, the size of the
capture file can be minimized.
The pdisplay program also provides a filtering mechanism to select
events from the capture file by LCN. Both these filtering mechanisms are
independent. The pdisplay program also provides many options for
displaying the captured X.25 or ISDN traffic (see “display” on page 31
for a detailed description of the display command).
