How SNMP Works

The following steps outline how the SNMP Service responds to management system requests:

1. The network management system uses host names or IP addresses to initiate requests.

2. The request contains a Get, Get Next, or Set command involving one or more objects. The request also includes a community name and validating information.

3. The SNMP Service receives the request. It verifies the community name and the source host name (or IP address) and selects the appropriate extension agent DLL to retrieve the requested information.

4. The extension agent DLL retrieves the requested information and passes it back to the SNMP Service.

5. The SNMP Service sends the completed request back to the SNMP manager.
