Ensure SNMP Readiness

Before scanning for SNMP devices, be sure that the following conditions are in place:

  • Devices for discovery are enabled for SNMP version 1, 2, or 3.

  • Devices enabled for SNMP v3 have a set password

  • Device Community String match the scan’s defined String

  • Devices limited to SNMP access per IP address or Host Name enable access to the RDS or the SysAid server

  • At least one device network adapters contain a valid MAC address on the following OID: 1.3.6.1.2.1.2.2.1.6.X.

Note

SysAid may not be able to locate devices whose MAC addresses adapter OIDs aren’t arranged in sequential order starting with 1.3.6.1.2.1.2.2.1.6.1.

This article describes the necessary steps to ensure SNMP readiness across a network.

By following these steps, Admins can ensure that the network devices are SNMP-ready and that SysAid can successfully retrieve and monitor SNMP data.

To ensure SNMP readiness, follow these steps:

  1. Enable SNMP on Devices
    Ensure that SNMP is enabled on all network devices that you want to monitor. This typically involves accessing the device's management interface and enabling SNMP services.

  2. Set Community Strings
    Configure the SNMP community strings on each device. Common community strings include 'public' for read-only access and 'private' for read-write access. Ensure that these community strings match the ones defined in SysAid's SNMP scan settings.

  3. Configure SNMP Versions
    Verify that the devices are configured to use the correct SNMP version (SNMP v1, v2c, or v3). Ensure that the SNMP version settings in SysAid match those on the devices.

  4. Network Access
    Ensure that the devices allow SNMP access from the SysAid server or Remote Discovery Service (RDS). This may involve configuring firewall rules or access control lists (ACLs) to permit SNMP traffic.

  5. Verify Device Compatibility
    Check that the devices support the OIDs (Object Identifiers) you intend to query. Consult the device documentation or vendor for details on supported OIDs.

  6. Test SNMP Connectivity
    Use SNMP testing tools to verify connectivity and data retrieval from the devices. Tools like SNMPwalk or SNMPget can help confirm that the devices are responding to SNMP queries.

  7. Update SysAid Configuration
    Ensure that SysAid's SNMP scan settings are correctly configured, including community strings, SNMP versions, and OIDs to query. Save the configuration and run a test scan to verify readiness.
