Only one copy of the capture daemon runs in each HP 9000 system. It
handles all analyzer sessions. The control of these sessions comes from
one or more invocations of the Display program. The pdisplay program
is designed to work on any HP-UX TTY device. Several copies of the
pdisplay program can independently control several analyzer sessions
simultaneously, or one pdisplay program may control multiple sessions.
The pcapture program can monitor all traffic on a particular X.25 link,
or it can 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 27 for
a detailed description of the display command).
