SNMP Setting
SNMP, the abbreviation of Simple Network Management Protocol, is used to refer to a collection of specifications for network management that include the protocol itself, the definition of data structures and associated concepts.
A management station performs the monitoring function by retrieving the value of MIB objects. The management station and agents are linked by a network management protocol that is SNMP. The SNMP includes three key capabilities: get, set and trap. A single management station can handle many agents as long as SNMP remains relatively “simple”, so the number can be high (hundreds or so).
The following picture is the typical configuration of protocols for SNMP. As for a
For an agent device that supports other applications, such as FTP, both TCP and UDP are required. An agent may issue a trap message in response to an event that affects the MIB and the underlying managed resources.
Note: There are no ongoing connections maintained between a management station and its agents. Instead, each exchange is a separate transaction between a management station and an agent.
Each agent is responsible for notifying the management station of any unusual event; for example, if the agent crashes and is rebooting, a link fails or an overload condition as defined by the packet load crosses some threshold. These events are communicated in SNMP messages known as traps.
