SNMP Setting (NB6W and NB6Plus4W only)

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 stand-alone management 
station, a manager process controls access to a central MIB at the management station and provides an 
interface to the network manager. The manager process achieves network management by using SNMP, which 
will be implemented on top of the UDP, IP and the relevant network-dependent protocols (e.g., Ethernet).

 

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 is no ongoing connection 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.
