Working with the Alarm Buffer
IPmux-16 maintains an Event Log File that stores up to 2000 events. All events are
time-stamped. The user can view the contents of the Event Log File via an ASCII
terminal or a Network Management Station. The user can also clear the contents
of the Log File.
Table 4-1 alphabetically presents the event types which appear on the Event Log
File, as well as the actions required to correct the event (alarm) indication.
To correct the reported problem, perform corrective actions in the given order
until the problem is corrected. If the problem cannot be fixed by carrying out the
listed actions, IPmux-16 MUST be checked by the authorized technical support
personnel.
