Snmp Traps - Cabletron Systems CBU-NM User Manual

3.1 This chapter
This chapter describes how alarms are processed and displayed. It also
explains the role of filters and how to use them.
3.2 The Alarm Database
The Alarm Database contains information about all the alerts PCNC has
received and processed. The database is stored within PCNC, but is
saved periodically (at intervals defined in PCNC.INI) to a disk file called
PCNC.DAT. When you exit the program, the latest version of the
database is saved. When you reload, PCNC automatically reads the
database back from this file.

3.3 SNMP Traps

PCNC is also capable of translating alarms to SNMP 'Trap-PDU' format.
This facility is available as an extension to the basic PCNC program, and
runs parallel to normal alert processing. The traps can be sent to any
standard NMS over TCP/IP, and they are forwarded automatically as
soon as they are processed.
If you use an NMS as the primary network monitor, you can prevent
PCNC storing the alarms it receives. This stops the Alarm Database
filling up with information that you will never use. The logging of alarms
is turned on or off by a setting in PCNC.INI (see Section 7.12.3).
