Adding a Monitor for SNMP Traps

  • Last updated on

An SNMP Trap monitor checks messages received (or trapped) from devices. Traps are the logical equivalent to an alert from the vendor's perspective, so they are important to consider when designing your own monitoring policies or considering how to customize your own monitors.

Onsite Manager has to be defined as an SNMP Trap receiver on the devices being monitored.

What You Can Do

You can

  • find out when a network device detects potential intrusions
  • be notified when a redundant Internet connection has been enabled
To add a monitor for an SNMP Trap
  1. In Service Center, click Configuration > Monitor & Alert Rules.
  2. From the Site list, select the site where the device is located.
  3. From the Device list, select the device to which you want to add a monitor.
  4. Click Add Monitor.
  5. Select SNMP Traps from the list.
  6. Click Add Monitor.
  7. In the Monitor tab, type a title for the monitor.
  8. Optionally, type a description for the monitor.
  9. Ensure the Enabled check box is selected.
  10. From the Generic Type list, select one of the following:
    (All) Use to monitor all traps.
    Cold Start Use to monitor when the SNMP device boots.
    Warm Start Use to monitor when the SNMP device reboots.
    Link Down Use to monitor when a network interface card (NIC) fails.
    Link Up Use to monitor when a network interface card (NIC) reinitializes.
    Authentication Failure Use to monitor when an SNMP device gets a request from an unrecognized community name.
    EGP Neighbor Loss Use to monitor when communication with the EGP (Exterior Gateway Protocol) peer fails.
    Enterprise Specific Use to monitor vendor-specific error conditions and error codes. In Enterprise OID, enter the id.

    The Enterprise Specific field supports both exact matches and matches that start with what you type. For example, typing 1.3.6.1.4.1.6876 includes 1.3.6.1.4.1.6876 as well as all the OIDs that begin with those numbers, such as 1.3.6.1.4.1.6876.2 and 1.3.6.1.4.1.6876.800.

  11. To configure an alert, see Setting Alert Actions.

    If you configure this alert, you can set the Variable Binding, or what data gets passed by the SNMP Trap. From the Variable Binding list, you can select Any to pass any data or you can select either Contains or Does Not Contain and type a value.

  12. Click Save.

    If you selected All from the Generic Type list, a warning message may appear informing you of the possible impact on storage costs, due to the large amount of data storage required. You must click Yes to continue adding the SNMP Trap monitor.
