Wireless-G VPN Broadband Router

Appendix E: SNMP Functions

SNMP (Simple Network Management Protocol) is a widely-used network monitoring and control protocol. Data is passed from a SNMP agent, such as the VPN Router, to the workstation console used to oversee the network. The Router then returns information contained in a MIB (Management Information Base), which is a data structure that defines what is obtainable from the device and what can be controlled (turned off, on, etc.).

SNMP functions, such as statistics, configuration, and device information, are not available without third-party Management Software. The Router is compatible with all HP Openview compliant software.
