SNMP Walk

Use the SNMP Walk tool (Tools icon > Device > SNMP Walk) to retrieve all SNMP MIB variables below a given root OID from a device on the network. The SNMP Walk tool may retrieve a large amount of SNMP data from the selected device depending on the specified root OID.

For the list of supported encryption protocols, see SNMPv3 Credentials for Discovery and Management.

You can also define the SNMP Walk settings in the Administrative Shell. For more information, see snmpwalk command.

To perform an SNMP Walk, do the following:

1. Open the Hostname or IP list and select the target device from the dropdown menu. there may be many pages of values in the dropdown. You can also enter a new value.
2. Open the Network View list and choose the network view containing the specified device.
3. In the Port field, type the target port.
4. In the Password field, enter the SNMP community string associated with the device (the default string for read-only operations is usually "public"). You may also leave the Password field blank (if a community string was previously discovered for the device or a default is used, then that string is used to automatically perform the walk).
5. Select SNMP version 1, 2c or 3.
6. If you selected version 1 or 2c, specify the Root OID.
7. If you selected version 3, specify the following:
   • Authentication Password
   • Authentication Protocol
   • Privacy Password
   • Privacy Protocol
   • Root OID
8. In the Root OID field, type the starting point for the SNMP walk as a symbolic name or in dotted-decimal notation. If a symbolic name is not recognized, try entering the dotted decimal notation instead.
9. Click Start. SNMP Walk displays progress through an SNMP Polling popup window.

The bottom of the SNMP Polling text output reports the result of the polling cycle, displaying a Polling Finished Normally message on successful completion.

To export the data, select the polling text, right-click and choose Copy.

To run the test again, click Restart.
