1. At a workstation,
access the web browser
and type the IP address for the PSA.
2. Log on to the PSA as an
administrator
. (The default user name is "admin" and the default password is
"admin".)
3. Under
Networking
on the menu, select
SNMP
. (See the
description of the fields
above for more
information.)
4. In
IP Address
, type the IP address for where the trap is to be sent.
5. In
Community Name
, type a community name for the trap packet. "Public" is a commonly used
community name.
6. In
Port
, specify the port number. Most SNMP agents receive traps on port 162.
7. Click
to complete the registration process. The SNMP agent is shut down and restarted. This
causes a trap to be sent out:
1: coldStart 1.3.6.1.6.3.1.1.5.1.
Trap Testing
The OID snmpTrapTest (1.3.6.1.4.1.11.2.46.2.1.10.4) will cause a trap to be sent to each registered host when set
to an integer value. For example, if an SNMP set is done on 1.3.6.1.4.1.11.2.46.2.1.10.4.0 with a value of 15, each
registered host will receive the trap TrapTest (1.3.6.1.4.1.11.2.46.2.2.0.100).
Trap Format
The PSA can generate three different traps:
●
coldStart
STATUS: current
DESCRIPTION: A coldStart trap signifies that the SNMPv2 entity, acting in an agent role, is reinitializing
itself and that its configuration may have been altered.
::= { snmpTraps 1 }
●
trapTest
OBJECTS: {snmpTrapTest}
STATUS: current
DESCRIPTION: When a set is done on trapTest this notification will be sent out.
::= { psaEventV2 100 }
●
logEventCriticalAlert
OBJECTS: { logCriticalCategory, logCriticalID, logCriticalMessageNumeric, logCriticalMessageString }
STATUS: current
DESCRIPTION: When a new critical entry is added to the logTable a notification of this type will be sent to
all entities registered for this notification.
::= { psaEventV2 1 }
This trap corresponds to critical entries in the
Event Log
. Six different events have been defined as critical:
❍
Cannot communicate with any domain controllers. Domain name:
❍
Cannot communicate with any WINS servers.
❍
Cannot communicate with any DNS servers.
❍
Cannot connect to printer-connection refused by printer.
❍
Cannot print due to problem at the printer.
❍
Critically high disk utilization - disk utilization is at 90-100% of capacity. If this log is added to the
event log the following trap will be sent.
