Networking Functions

Interactions between the NMS and managed devices can be any of four

different types of commands: reads, writes, traversal operations, and

traps.

Reads - To monitor managed devices, NMSs read variables main-

tained by the devices.

Writes - To control managed devices, NMSs write variables stored

within the managed devices.

Traversal operations - NMSs use these operations to determine

which variables a managed device supports and to sequentially

gather information from variable tables (such as IP routing tables) in

managed devices.

Traps - Managed devices use traps to asynchronously report certain

events to NMSs.

Accessing the SNMP interface requires a tool, such as a network man-

agement station. The management station relies on an agent at a device

to retrieve or update the information at the device, including device con-

figuration, status, and statistical information. This information is viewed

as a logical database, called a Management Information Base (MIB). MIB

modules describe MIB variables for a variety of device types and com-

puter hardware and software components.
