a single privacy protocol. SNMPv2 messages are communicated between two
parties. An SNMPv2 entity can define multiple parties, each with different
parameters. For example, different parties can use different authentication and/or
privacy protocols.
Management protocol --
A management protocol is used to convey management
information between agents and NMSs. SNMP is the Internet community's de facto
standard management protocol.
The most basic elements of the Internet management model are graphically
represented in Figure 1.
Figure 1: The Internet Management Model
Interactions between the NMS and managed devices can be any of four different
types of commands:
Reads --
To monitor managed devices, NMSs read variables maintained by the
devices
Writes -- To cont
rol 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
