Here you can find a table with a list of common OID keys used by manufacturers of network devices. You can also manually add device specific OIDs as necessary. OID mapping allow you to map data imported from an SNMP scan into a corresponding field on the asset form.

To add a new OID, enter the OID and a display name that defines the function of that OID. Then select a field on the asset form to map the data to. Afterwards, whenever that OID is detected in an SNMP scan, the data it contains will be copied to the chosen field on the asset. Check with the vendor of your devices for details on specific information you can obtain from each device.

You can choose to map more than one OID to the same Asset field. If two or more OIDs point to the same field on an asset, the first encountered value will be used and the rest ignored.

Editing SNMP OIDs

SysAid allows you to write to your SNMP devices. Check the box Editable if you would like to be able to edit a specific SNMP field from within SysAid. You may edit the desired field from the asset form (go to the asset list and open the asset you would like to edit).

Note: On the asset form, the write to SNMP OID button is only available for SNMP devices. For non-SNMP devices, asset fields are edited normally.

Focusing queries from the SNMP discovery tool

There may be cases where a specific SNMP device has an OID that is unique to that type of device. You can direct the SNMP discovery tool to query that OID only for that particular type of device, thereby speeding up your SNMP scans. An example would be an OID for a printer that indicates low toner. You would not need to query this OID for any device that is not a printer. This feature is only available for custom OIDs that you add, not those that come preconfigured with SysAid.

To enable selective SNMP scanning for a particular OID :

  1. First, make sure that you've added the custom OID.
  2. Click the filter icon CustomizedSnmpOidsfilesimage0091.gif for that OID. The Expression Builder opens.
  3. Choose the desired filter for that OID. An example could be "type = printer."
  4. Click Create Filter to apply your filter. This closes the Expression Builder.
  5. Click Save.
