Example 2.12. Sending SNMP Traps to an SNMP Trap Receiver
To enable generation of SNMP traps for all events with a severity greater than or equal to Alert to an SNMP trap
receiver with an IP address of 195.11.22.55, follow the steps outlined below:
CLI
gw-world:/> add LogReceiver EventReceiverSNMP2c my_snmp IPAddress=195.11.22.55
Web Interface
1. Go to Log & Event Receivers > Add > SNMP2cEventReceiver
2. Specify a name for the event receiver, for example my_snmp
3. Enter 195.11.22.55 as the IP Address
4. Enter an SNMP Community String if needed by the trap receiver
5. Click OK
The system will now be sending SNMP traps for all events with a severity greater than or equal to Alert to an
SNMP trap receiver at 195.11.22.55.
2.2.4. Advanced Log Settings
The following advanced settings for logging are available to the administrator:
Send Limit
This setting limits how many log packets NetDefendOS may send out per second. This value should
never be set too low, as this may result in important events not being logged, nor should it be set too
high.
A situation where setting too high a value may cause damage is when NetDefendOS sends a log
message to a server whose log receiver is not active. The server will send back an ICMP
UNREACHABLE message, which may cause NetDefendOS to send another log message, which in
turn will result in another ICMP UNREACHABLE message, and so on. By limiting the number of
log messages NetDefendOS sends every second, you avoid encountering such devastating
bandwidth consuming scenarios.
Default: 3600 (once per hour)
Alarm Repetition Interval
Note
NetDefendOS sends SNMP Traps which are based on the SNMPv2c standard as
defined by RFC1901, RFC1905 and RFC1906.
