MANAGEMENT VIA SNMP

the manager software, and result in a response by the agent. The third operation type, the TRAP, allows the agent to send an unsolicited message to the manager. This operation is typically used as an alert to a potential problem, or a change in device status.

MIB Objects

A number of different MIB specifications have been defined for managing network equipment; some are standard, others are proprietary. SNMP-compliant devices typically support one or more standard MIBs defined by the IETF, in the form of Request for Comments (RFC) documents. These allow for a common method of managing devices, such as bridges and hubs, and network interfaces, such as Ethernet and Token Ring.

The main standard MIB, referred to as MIB II, provides an over- all view of the managed agent and is supported, at least in part, by all SNMP agents. In addition, proprietary MIB extensions are defined by commercial vendors for managing device-specific functions of their products.

The standards supported by the TigerSwitch 100 units include:

RFC 1493 - Definitions of Managed Objects for Bridges

RFC 1213 - Simple Network Management Protocol
