5.5.3SNMP Trap Alerts Setup

The OpenComms EM may be configured to send SNMP trap alerts to a computer whenever the status of a sensor changes from normal to a warning or critical state, as well as a return-to-normal alert when the reading falls within the normal range. These alerts may be sent to up to four IP addresses, typically Network Management Station (NMS).

If you activate SNMP traps, see also 5.7.2 - SNMP Information.

To generate SNMP traps when a sensor reading crosses a threshold, log in (see 5.1 - Open the Web Interface and Log In) and:

•Click on the SNMP Traps tab at the top of the Web interface, as shown below.

•Click on the SNMP Traps link on the left side of the window. The right side of the window dis- plays setup information for SNMP Trap alerts, as shown above.

•Configure the following settings for each of the four Traps you wish to use:

•In the State box, click on the Down arrow and select On to activate or Off to de-activate SNMP trap alerts

•In the Destination IP box, enter the IP address of the computer where traps should be sent.

•In the Community Name box, enter the community string of the computer where traps are directed—for example, liebert or public. Community strings are case-sensitive.

•Click on the Apply button to keep your changes. (Or click Reset to cancel the changes.)
