STP
Spanning Tree Protocol is an OSI layer-2 protocol which ensures a loop free topology for
any bridged LAN. The original STP protocol is now obsolete by RSTP.
Switch ID
Switch IDs (1-16) are used to uniquely identify the switches within a stack. The Switch ID
of each switch is shown on the display on the front of the switch and is used widely in the
web pages as well as in the CLI commands.
SyncE
SyncE Is an abbreviation for Synchronous Ethernet. This functionality is used to make a
network 'clock frequency' synchronized. Not to be confused with real time clock
synchronized (IEEE 1588).
T
TACACS+
TACACS+ is an acronym for Terminal Acess Controller Access Control System Plus. It is
a networking protocol which provides access control for routers, network access servers
and other networked computing devices via one or more centralized servers. TACACS+
provides separate authentication, authorization and accounting services.
Tag Priority
Tag Priority is a 3-bit field storing the priority level for the 802.1Q frame.
TCP
TCP is an acronym for Transmission Control Protocol. It is a communications protocol
that uses the Internet Protocol (IP) to exchange the messages between computers.
The TCP protocol guarantees reliable and in-order delivery of data from sender to
receiver and distinguishes data for multiple connections by concurrent applications (for
example, Web server and e-mail server) running on the same host.
The applications on networked hosts can use TCP to create connections to one another.
It is known as a connection-oriented protocol, which means that a connection is
established and maintained until such time as the message or messages to be
exchanged by the application programs at each end have been exchanged. TCP is
responsible for ensuring that a message is divided into the packets that IP manages and
for reassembling the packets back into the complete message at the other end.
Common network applications that use TCP include the World Wide Web (WWW), e-mail,
and File Transfer Protocol (FTP).
TELNET
TELNET is an acronym for TELetype NETwork. It is a terminal emulation protocol that
uses the Transmission Control Protocol (TCP) and provides a virtual connection between
TELNET server and TELNET client.
TELNET enables the client to control the server and communicate with other servers on
the network. To start a Telnet session, the client user must log in to a server by entering a
valid username and password. Then, the client user can enter commands through the
Telnet program just as if they were entering commands directly on the server console.
TFTP
TFTP is an acronym for Trivial File Transfer Protocol. It is transfer protocol that uses the
