Dell EMC iDRAC Service Module 4.2.0.0 User’s Guide

Configuring the In-Band SNMP Get feature—Linux

1. To start the iSM installation, execute ./setup.sh at the command line.
2. Read and accept the license agreement to proceed with the installation.
   A list of feature is displayed.
3. To select the Access via SNMP Get sub-option under the iDRAC access via Host OS feature, enter 4.c , and press Enter.
4. After the feature is enabled, enter I and press Enter, to start the installation process of the selected features.
5. After the installation is completed, start the iDRAC Service Module process.
   If the SNMP Agent service is not enabled on iDRAC, iSM configures and enables the SNMP Agent.
6. To view the SNMP Agent properties, go to Settings on the iDRAC GUI.
7. Click iDRAC Service Module Setup.
8. Under Monitoring session, verify 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, to enable the PuTTY Security Alert.
11. Log in to iDRAC using the proper credentials.
12. Type racadm get iDRAC.ServiceModule.HostSNMPGet and enter.
    Verify that HostSNMPGet is enabled.

    If the In-Band SNMP Get feature is not enabled during iDRAC Service Module installation, you can enable it using the following iDRAC UI or the RACADM commands:

    • Through the iDRAC UI—iDRAC Settings->Settings->iDRAC Service Module Setup->Enable SNMP Get via Host OS->Enable or Disable
    • Through the RACADM—racadm set idrac.servicemodule.HostSnmpGet "Enabled" or "Disabled"

    NOTE iDRAC UI or RACADM commands for the In-Band SNMP Get feature are applicable only for PowerEdge yx4x and yx5x servers. On PowerEdge yx3x servers, you must use the iSM installer for enabling and disabling this feature.

    When the SNMP Get feature is enabled, it creates an iDRAC account iSMSnmpUser for SNMPv3 support internally. If the account already exists, iSM logs the following error message and the feature is disabled.

    Unable to create the user \"iSMSnmpUser"\ on iDRAC because the username already
    exists. The SnmpGet via Host OS feature will be disabled.

    In such cases, you must remove the “iSMSnmpUser” in iDRAC and disable and enable the Enable SNMP Get via Host OS feature on iDRAC UI once again. The iSMSnmpUser account created by iSM is deleted when the feature is disabled or iSM is uninstalled. The SNMP Get feature will not work when there are maximum number of iDRAC accounts created (16) and there are no further slots.
