Prestige 2602HWNLI-D7A Support Notes

The current Internet-standard MIB, MIB-II, is defined in RFC 1213 and contains 171 objects. These objects are grouped by protocol (including TCP, IP, UDP, SNMP, and other categories, including 'system' and 'interface.'

The Internet Management Model is as shown in figure 1. Interactions between the NMS and managed devices can be any of four different types of commands:

6.Reads

Read is used to monitor the managed devices, NMSs read variables that are maintained by the devices.

7.Writes

Write is used to control the managed devices, NMSs write variables that are stored in the managed devices.

8.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 table) in managed devices.

9.Traps

The managed devices to asynchronously report certain events to NMSs use trap.
