Dell EMC iDRAC Service Module 3.1 User’s Guide

Enabling the In-band SNMP Get feature—Linux

Net-snmp package should be installed and configured to accept SNMP requests from remote systems.
For installing the in-band SNMP get feature through installer complete the following tasks:
  1. Start the iSM installation using the script by executing ./
  2. Review the license agreement and accept to proceed with the installation.
  3. On the next page, the list of features are shown. Select the Access via SNMP Get sub option under the iDRAC access via Host OS feature by entering 4.c , and press Enter.
  4. After the feature is enabled, start the installation process of the selected features by entering I and press Enter.
  5. After the installation is finished successfully, start the iDRAC Service Module process. If SNMP Agent service is not enabled on iDRAC, iSM configures and enables the SNMP Agent.
  6. To view the SNMP Agent properties, on the iDRAC GUI, Go to Settings.
  7. Click iDRAC Service Module Setup.
  8. Under Monitoring session, view that SNMP Get via Host OS option is enabled.
  9. Open a new ‘ PuTTY Configuration’ window, provide your Host Name IP address and click Open.
  10. Click Yes, for the PuTTY Security Alert.
  11. Log in to iDRAC using the proper credentials.
  12. Type racadm get iDRAC.ServiceModule.HostSNMPGet and enter. You can view that HostSNMPGet is enabled.
    • NOTE: If the In-Band SNMP Get feature was not enabled during the Installation of iSM, it can be enabled later through iDRAC GUI/Racadm command.
      • Through iDRAC GUI — iDRAC Settings->Settings->iDRAC Service Module Setup->Enable SNMP Get via Host OS->Enable or Disable
      • Through Racadm — racadm set idrac.servicemodule.HostSnmpGet "Enabled"or "Disabled"
    • NOTE: iDRAC GUI/Racadm commands for In-Band SNMP Get feature is applicable only for 14 th Generation of servers. On 12 th and 13 th Generation servers, you must use the iSM installer for enabling/disabling this feature.
    • NOTE: When SNMP Get feature is enabled, it creates an iDRAC user “ iSMSnmpUser” for SNMPv3 support internally. If the user already exists, iSM logs an error message saying "Unable to create the "iSMSnmpUser" on iDRAC because the username already exists. Then SnmpGet via Host OS feature is disabled." and the feature is disabled. In such cases, the you must remove the “iSMSnmpUser” in iDRAC and disable and enable the Enable SNMP Get via Host OS feature on iDRAC GUI once again. The user, “iSMSnmpUser” created by iSM is deleted when the feature is disabled or iSM is uninstalled.
