APPENDIX D
Simple Network Management Protocol (SNMP)
The Raven X can be configured as an SNMP agent and supports SNMPv2c and SNMPv3.
SNMP Overview
The Simple Network Management Protocol (SNMP) was designed to allow remote management and monitoring of a variety of devices from a central location. The SNMP management system is generally composed of agents (such as your Raven X, a router, a UPS, a web server, a file server, or other computer equipment) and a Network Management Station (NMS) which monitors all the agents on a specific network. Using the management information base (MIB), an NMS can include reporting, network topology mapping, tools to allow traffic monitoring and trend analysis, and device monitoring.
Authentication ensures SNMP messages coming from the agent, such as the Raven X, have not been modified and the agent may not be queried by unauthorized users. SNMPv3 uses a User- Based Security Model (USM) to authenticate and, if desired or supported, message encryption. USM uses a user name and password specific to each device.
Management Information Base (MIB)
The management information base (MIB) is a type of database used to compile the information from the various SNMP agents. Reports from various agents, such as the Raven X, are sent as data in form designed to be parsed by the NMS into its MIB. The data is hierarchical with entries addressed through object identifiers.
SNMP Traps
SNMP traps are alerts that can be sent from the managed device to the Network Management Sta- tion when an event happens. Your Raven X is capable of sending the linkUp trap when the network connection becomes available.
Raven X SNMP Configuration
To configure your Raven X to work as an SNMP agent, you can use either Wireless Ace, or a termi- nal connection to configure the modem using AT commands. In Wireless Ace, the SNMP com- mands are all on the Other menu option.
