Send SNMP traps from SEM to other applications by turning on the SNMP Request Service

Turn on the SNMP Request Service to allow SEM to output SNMP traps to one or more applications on your network. Starting with version 6.3.0, SEM supports SNMP version 2 and SNMP version 3.

The SNMP Request Service must be turned on in SEM to do the following:

  • Send SNMP traps to devices when SEM rules fire.
  • Use NPM and the SolarWinds Orion Web Console to monitor SEM system resources such as CPU and memory.

SEM versions older than version 6.3.0 have the following limitations:

  • Only support SNMP version 2
  • Can only send SNMP traps to devices when rules fire
  • Do not support sending health or status updates to other devices over SNMP

To enable or disable the SNMP Request Service

  1. Open the CMC command line. See Log in to the SEM CMC command line interface for steps.

  2. At the cmc> prompt type:

    service

  3. At the cmc::service> prompt type:

    snmp

    A prompt like the following appears:

    SNMP Trap Logging Service is DISABLED
    Would you like to ENABLE the SNMP Trap Logging Service? [Y/n]

    The SNMP Trap Logging Service is not the same as the SNMP Request Service. The SEM SNMP Trap Logging Service receives SNMP traps from other devices, whereas the SEM SNMP Request Service outputs SNMP traps outside of SEM. See Enable SEM to receive SNMP traps by turning on the SNMP Trap Logging Service for more information.

  4. Do not change the status of this service unless you know what you are doing.

    To go to the next step, type Y or n,and then press Enter.

    A prompt like the following appears:

  6. Type the port number that SEM should use to communicate with SolarWinds Network Performance Manager (NPM), and then press Enter.

    Ports 161 and 162 are standard.

    The following prompt appears:

    Enter the username to access SNMP on SEM (default: orion):
  7. Type the user name to use, and then press Enter.

    The following prompt appears:

    Enter the password hashing algorithm (SHA1, MD5 or NO for no authentication, default: SHA1):
  8. Enter an option, and then press Enter.

    The following prompt appears:

    Enter the authentication password (default: orion123):
  9. Type the password, and then press Enter.

    The following prompt appears:

    Enter the communication encryption algorithm (AES128, DES56 or NO for no encryption, default: AES128):
  10. Enter an option, and then press Enter.

    The following prompt appears:

                        Enter the encryption key (default: orion123):
