Glossary
SFP Small form-factor pluggable, a type of shortwave or longwave optic
transceiver.
SMTP Simple Mail Transfer Protocol, a TCP/IP protocol that allows users to
create, send, and receive text messages. SMTP protocols specify how
messages are passed across a link from one system to another. They
do not specify how the mail application accepts, presents or stores the
mail.
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.
