MONITOR

Command

MONITOR -- Enable / disable traffic monitoring (tracing)

Synopsis

MON[ITOR] [on | off]

Description

The MONITOR command is used to enable or disable the display of incoming and outgoing traffic.

The optional argument may be "ON" or "OFF". The former enables the display, and the latter disables it. If no argument is supplied, the current setting is reported.

If used at the console, this command enables and disables tracing to the current console window, and works in conjunction with the <F2> (monitor toggle) key.

If used by a remote sysop, monitored frames are sent to him instead of the console window. In order to avoid overloading the link, the MPORT setting is cleared every time monitoring is enabled, so the sysop must then issue the MPORT command to select which port(s) to monitor.

The console may override a remote sysop's settings.

Examples

MON ON - Enables tracing. MON OFF - Disables tracing.

Limitations

Only one sysop may receive the trace display at any one time. Remote sysops cannot trace activity on the port on which they are uplinked.

Note

Remote sysops must ensure that their link with the router is capable of carrying the large volume of traffic resulting from tracing. Attempting to trace too many ports / too much detail on a slow link may result in poor performance. You have been warned!

Availability

The MONITOR command is available only to console and remote sysops.
