Chapter 6 Managing and Monitoring via the CLI
SNMP provides the ability to send traps, or notifications, to advise an administration application (an
SNMP management console, typically) when one or more conditions have been met. Traps are network
packets that contain data relating to a component of the system sending the trap. Traps are generated
when a condition has been met on the SNMP agent (in this case, the Cisco IronPort appliance). After the
condition has been met, the SNMP agent then forms an SNMP packet and sends it over port 162, the
standard SNMP trap port. In the example below, the trap target of snmp-monitor.example.com and the
Trap Community string are entered. This is the host running the SNMP management console software
that will receive the SNMP traps from the Cisco IronPort appliance.
You can configure SNMP traps (enable or disable specific traps) when you enable SNMP for an
interface. To specify multiple trap targets: when prompted for the trap target, you may enter up to 10
comma separated IP addresses.
In the following example, the snmpconfig command is used to enable SNMP on the “PublicNet”
interface on port 161. A passphrase for version 3 is entered and then re-entered for confirmation. The
system is configured to service version 1 and 2 requests, and the community string public is entered for
GET requests from those versions 1 and 2. The trap target of snmp-monitor.example.com is entered.
Finally, system location and contact information is entered.
