SSH Secure Shell is a secure replacement for remote access functions, including

Telnet. SSH can authenticate users with a cryptographic key, and encrypt

data connections between management clients and the switch.

STA Spanning Tree Algorithm is a technology that checks your network for any

loops. A loop can often occur in complicated or backup linked network

systems. Spanning Tree detects and directs data along the shortest

available path, maximizing the performance and efficiency of the network.

TCP/IP Transmission Control Protocol/Internet Protocol. Protocol suite that

includes TCP as the primary transport protocol, and IP as the network layer

protocol.

TELNET Defines a remote communication facility for interfacing to a terminal device

over TCP/IP.

TFTP Trivial File Transfer Protocol. A TCP/IP protocol commonly used for software

downloads.

UDP User Datagram Protocol. UDP provides a datagram mode for packet-

switched communications. It uses IP as the underlying transport

mechanism to provide access to IP-like services. UDP packets are delivered

just like IP packets – connection-less datagrams that may be discarded

before reaching their targets. UDP is useful when TCP would be too

complex, too slow, or just unnecessary.

UTC Universal Time Coordinate. UTC is a time scale that couples Greenwich

Mean Time (based solely on the Earth’s rotation rate) with highly accurate

atomic time. The UTC does not have daylight saving time.

VLAN Virtual LAN. A Virtual LAN is a collection of network nodes that share the

same collision domain regardless of their physical location or connection

point in the network. A VLAN serves as a logical workgroup with no

physical barriers, and allows users to share information and resources as

though located on the same LAN.
