Glossary
SNMP Simple Network Management Protocol, a TCP/IP protocol that
generally uses the User Datagram Protocol (UDP) to exchange
messages between a management information base (MIB) and a
management client residing on a network.
Storage Area Network A network linking servers or workstations to disk arrays, tape
backup systems and other devices, typically over Fibre Channel.
Subnet Mask Used by a computer to determine whether another computer with
which it needs to communicate is located on a local or remote
network. The network mask depends upon the class of networks to
which the computer is connecting. The mask indicates which digits to
look at in a longer network address and allows the router to avoid
handling the entire address. Subnet masking allows routers to move
the packets more quickly. Typically, a subnet may represent all the
machines at one geographic location, in one building, or on the same
local area network.
Switch Priority Value configured into each switch in a fabric that determines its
relative likelihood of becoming the fabric’s principal switch.
T
TCP/IP Transmission Control Protocol/Internet Protocol.
Topology Logical and/or physical arrangement of stations on a network.
Trap An asynchronous (unsolicited) notification of an event originating on
an SNMP-managed device and directed to a centralized SNMP
Network Management Station.
Toggle To change the state of a feature/function that has only two states. For
example, if a feature/function is enabled, toggling changes the state to
disabled.
U
ULP Upper Layer Protocol, the protocol user of FC-4, including IPI, SCSI,
IP, and SBCCS.
