T-Series Traffic Director Installation, Configuration and Administration Guide 5-17
Configuring SNMP
• Critical
• Major
• Minor
• Warning
• Informational
For example, if you set a Warning severity level for the SNMP alarm named
LOGIN-FAILURE, the trap messages generated when there is a login failure will be
assigned with the Warning severity level. You can also configure an SNMP alarm to log the
corresponding trap messages generated whenever the condition on that alarm is met.
To configure an SNMP alarm:
At the T1000 command prompt, use the following commands to configure an SNMP alarm
and verify the configuration:
set snmp alarm trapName [-thresholdValue positive_integer [-normalValue
positive_integer]] [-time secs][-state {ENABLED | DISABLED}] [-severity
severity] [-logging {ENABLED | DISABLED} ]
show snmp alarm [trapName]
Configuring Traps
After configuring the alarms, you need to specify the trap listener to which the T1000 will
send the trap messages. Apart from specifying parameters like IP address and the
destination port of the trap listener, you can specify the type of trap (either generic or
specific) and the SNMP version.
You can configure a maximum of 20 trap listeners for receiving either generic or specific
traps. You can also configure the T1000 to send SNMP trap messages with a source IP, other
than the T1000 IP address (NSIP), to a particular trap listener. You can set the source IP to
either a mapped IP address (MIP) or a subnet IP address (SNIP) configured on the T1000 .
You can also configure the T1000 to send trap messages based on a severity level to a trap
listener. For example, if you set the severity level as Minor for a trap listener, all the trap
messages of the severity level equal to or greater than Minor (Minor, Major, and Critical)
will be sent to the trap listener.
You need to specify a community string if you have defined the same in the trap listener.
This string is sent in the trap messages to the specified trap listener. The trap listener will
accept a trap message only when the community string defined in the trap message matches
the community string defined in the trap listener; otherwise, the trap message is dropped.
