MANAGEMENT PROTOCOLS
SNMP is used for remote configuring of system and bridge parameters,
monitoring statistics, and performing advanced management. BOOTP is
available for the Campus-REX to download system software code.
SNMP
This messaging protocol specifies how to send information between a
Network Management Station (NMS) and managed devices on a network.
Managed devices (such as the Campus-REX) have agent software or
firmware that interprets SNMP requests and responds to them. The NMS
communicates with the agents in the managed devices to:
• set configuration options
• read configuration information
• read status parameters
A Management Information Base (MIB) defines these configuration and
status parameters. The Internet Engineering Task Force (IETF) specifies
standard MIBs for certain types of devices, ensuring that any NMS can
manage them. Additionally, vendors can issue proprietary MIBs for their
devices that provide higher management functionality.
The following table shows the configuration parameters that must be
maintained and restored to the Campus-REX through the system’s local
console port. These parameters are stored in the Campus-REX NVRAM
(non-volatile memory) and are used in subsequent initializations.
