Glossary
small form factor
pluggable
transceivers
SFP transceivers. Laser-based optical transceivers for a wide range of
networking applications requiring high data rates. The transceivers,
which are designed for increased densities, performance, and
reduced power, are well-suited for Fibre Channel applications.
SMTP See simple mail transfer protocol.
SNMP See simple network management protocol.
SNMP community See simple network management protocol community.
SNMP community

See simple network management protocol community name.
SNMP management
station
See simple network management protocol management station.
SNMP v1 See simple network management protocol version 1.
SNMP v2 See simple network management protocol version 2.
SONET See synchronous optical network.
SRAM See static random access memory.
state The state of the switch or director. Possible values include online,
offline, testing, and faulty. See
offline state; online state.
static random access
memory
SRAM. SRAM is microprocessor-cache random access memory. It is
built internal to the microprocessor or on external chips. SRAM is
fast, but relatively expensive (D). Contrast with
dynamic random
access memory.
stored addresses In S/390 mode, a method for configuring addresses.
subnet A portion of a network that shares a common address component. On
transmission control protocol/Internet protocol (TCP/IP) networks,
subnets are defined as all devices whose IP addresses have the same
prefix. Dividing a network into subnets is useful for both security and
performance reasons. IP networks are divided using a subnet mask.
subnet mask A 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
