SNMP MANAGEMENT INFORMATION BASE

Simple Network Manage Protocol (SNMP) specifies how to send information between a network management station and managed devices on a network. Managed devices run a program called an agent. The agent interprets SNMP requests and responds to them. The management station communicates with the agents in the managed devices to:

•set configurations

•read configurations

•read status parameters

Management Information Bases (MIBs) define these configurations and status parameters. The Internet Engineering Task Force (IETF) specifies standard MIBs for certain types of devices, ensuring any generic SNMP application can manage them. Other vendor-specific MIBs such as those used by ADC, define the configuration, status, trap, and performance parameters unique to the WorldDSL product line.

The EMU-830 performs as a proxy agent when managing line units. Each managed device has configuration, status, and statistical information that defines its functionality and operation capabilities.

There are a total of six MIB files that define the SNMP management interface of the ADC WorldDSL product. These files should be copied into the Network Manager Client MIB Subdirectory. Once copied onto the desired drive they can be easily accessed by the Network Manager’s MIB compiler. The six MIB files are named as follows:
