Diagnostic Trace
Feature
NetPath 100 has a built-in Diagnostic Trace feature which can be used to monitor ML-
PPP connection activity. This feature is equivalent to and compliments the diagnostic
trace capabilities provided by several other major manufacturers of routers and net-
work switching equipment.
The Trace feature is accessed via VT-100 dial-in to the NetPath 100 ISDN Adapter
module. A dial-in call is routed to the ISDN Adapter by the unit’s integrated call direc-
tor (refer to Figure 2-9 of this manual).
The steps to activate a trace are as follows:
1. Dial-in through the unit’s modem line. The setup string must include the digits to
direct the call to the ISDN Adapter module (“w,,,4”).
2. The ISDN startup display and a password prompt will appear. Enter any character
followed by ENTER. “Login for PPP TRACE messages” should be displayed.
NOTE: If the startup display does NOT have “ISDN” in its first line, then the call
was not properly routed to the ISDN Adapter. Hang up, recheck the setup string
and place the call again.
3. Turn trace ON by entering the command, “TRACE PPPTRACE” followed by
ENTER.
4. Start diagnostic message display by entering the command, “DIAG” followed by
ENTER.
The first line will display, “Entering Diagnostic Mode - Press Esc To go back to OCP
Mode”. Thereafter, each event message will be displayed as it occurs.
The Trace Diagnostic Mode will remain active until the user presses the “Esc” key or
an inactivity logout occurs (5 minutes without keystroke.)
