262 Glossary
sequence
A group of related frames transmitted in the same direction between two N_Ports.
sequence initiator
The N_Port that begins a new sequence and transmits frames to another N_Port.
sequence recipient
Serializing and deserializing circuitry. A circuit that converts a serial bit stream into parallel characters, and
vice-versa.
SFP
Small-form-factor pluggable. A transceiver used on 2 Gbps or 4 Gbps switches that replaces the GBIC.
Simple Name Server (SNS)
A switch service that stores names, addresses, and attributes for up to 15 minutes and provides them as required to
other devices in the fabric. SNS is defined by Fibre Channel standards and exists at a well-known address. Also
called a directory service or Name Server.
Single CP Mode
The
-s
option of the
firmwaredownload
command. Using
firmwaredownload -s
enables Single CP Mode.
In the Core Switch 2/64, Single CP Mode enables a user to upgrade a single CP card and to select full-install,
auto-reboot, and auto-commit.
SNMP
Simple Network Management Protocol. An Internet management protocol that uses either IP for network-level
functions and UDP for transport-level functions, or TCP/IP for both. Can be made available over other protocols,
such as UDP/IP, because it does not rely on the underlying communication protocols.
SNS
See Simple Name Server (SNS) .
SOF
Start of frame. A group of ordered sets that marks the beginning of a frame and indicates the class of service the
frame will use.
SONET
Synchronous optical network. A standard for optical networks that provides building blocks and flexible payload
mappings.
special character
A 10-bit character that does not have a corresponding 8-bit value but is still considered valid. The special character
indicates that a specific transmission word is an ordered set. This is the only type of character to have five 1s or 0s
in a row.
