5.5 SNMP
Settings
Simple Network Management Protocol (SNMP) is an Application Layer designed
specifically for managing and monitoring network devices. SNMP enables network
management stations to read and modify the settings of gateways, routers, switches,
and other network devices. Use SNMP to configure system features for proper operation,
monitor performance and detect potential problems in the Switch, switch group or
network. Managed devices that support SNMP include software (referred to as an agent),
which runs locally on the device. A defined set of variables (managed objects) is
maintained by the SNMP agent and used to manage the device. These objects are
defined in a Management Information Base (MIB), which provides a standard
presentation of the information controlled by the on-board SNMP agent. SNMP defines
both the format of the MIB specifications and the protocol used to access this
information over the network.
5.6 Traps
Traps are messages that alert network personnel of events that occur on the Switch.
The events can be as serious as a reboot (someone accidentally turned OFF the Switch),
or less serious like a port status change. The Switch generates traps and sends them to
the trap recipient (or network manager). Typical traps include trap messages for
Authentication Failure, Topology Change and Broadcast\Multicast Storm.
5.7 MIBs
The Switch in the Management Information Base (MIB) stores management and counter
information. The Switch uses the standard MIB-II Management Information Base module.
Consequently, values for MIB objects can be retrieved from any SNMP-based network
management software. MIB values can be either read-only or read-and-write.
