Simple Network Management Protocol (SNMP)
is a protocol
that controls how a management station gains information from a
device. SNMP is composed of three areas:
A set of rules that define
how
a management station can
communicate with a device.
A
Management Information Base (MIB)
that defines
what
i
nformation can be obtained from the device by the
management station. Every SNMP-manageable device has a
MIB, which is a list of information about it.
Unsolicited messages called
Traps
, which work differently to the
usual request/reply management communication. You can
configure a device so that it generates a trap if a certain
condition occurs, for example a port partitioning. The trap will
be sent to the management station to inform it of the
occurrence.
Device
is a term that is used to refer to a piece of network
equipment. Every device has a unique address that is used to
identify it on the network.
Internet Protocol (IP)
is a data communication protocol used to
connect computers and data equipment into computer networks. It
is used on a large international network called the Internet, which
is composed of universities, government facilities, research
institutions, and private companies.
