are subject to change without notice.

PRELIMINARY

SUBNET MASK A decimal number (four integers) which specifies the logical network

subnet of the terminal. A typical subnet mask is 255.255.255.0. Also see

Netmask.

TACACS+ Terminal Access Controller Access Control System Plus. TACACS+ is a logon

authentication protocol that uses software running on a central server to

control access to TACACS-compliant devices on 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.

TIMEOUT The elapsed time (in seconds) that ECView waits for a response from a

device.

TFTP (TRIVIAL FILE

TRANSFER PROTOCOL)

A file-transfer protocol for downloading files.

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.

UNICAST PACKET A packet transmitted to a specific node on the network.
