Configure a Trap Destination with ESXCLI

You can use ESXCLI to configure a trap destination and send traps.

Specify one of the options listed in Connection Options for ESXCLI Host Management Commands in place of <conn_options>.

Procedure

  1. Make sure a community is set up. 
    esxcli system snmp get <conn_options>

Current SNMP agent settings:
Enabled: 1
UDP port: 161
Communities: public
Notification targets:
  2. Set the target address, port number, and community. 
    esxcli <conn_options> system snmp set -t target.example.com@163/public

    Each time you specify a target with this command, the settings you specify overwrite all previously specified settings. To specify multiple targets, separate them with a comma.

    You can change the port that the SNMP agent sends data to on the target using the --targets option. That port is UDP 162 by default.

  3. (Optional) Enable the SNMP agent if it is not yet running. 
    esxcli <conn_options> system snmp set --enable=yes
  4. (Optional) Send a test trap to verify that the agent is configured correctly. 
    esxcli <conn_options> system snmp test
    The agent sends a warmStart trap to the configured target.
