LAN Watch and SNMP

LAN Watch by Network or LAN Watch by Probe in the Discovery module uses an existing VSA agent on a managed machine to periodically scan the local area network for any and all new devices connected to that LAN since the last time LAN Watch ran.

The LAN Watch discovery machine issues the SNMP requests to the SNMP devices it discovers on the same LAN. So you must run LAN Watch first to have access to SNMP-enabled devices using the VSA.

To include SNMP devices in the discovery scan performed by LAN Watch:

1. Select a machine ID on the same LAN as the SNMP devices you want to discover.
2. Check the Enable SNMP checkbox.
3. Enter a community name in the Read Community Name and Confirm fields.

   A community name is a credential for gaining access to an SNMP-enabled device. The default "read" community name is typically public, in all lower case, but each device may be configured differently. You may have to identify or reset the community name on the device directly if you're not sure what community name to use.

4. Click the Schedule and Scan button at the bottom of the Edit Network dialog. This will start the scan immediately.
5. Review discovered SNMP-enabled devices using the Monitor > Assign SNMP page.
