Glossary and Acronyms
D
SMTP
Simple Mail Transfer Protocol is a standard host-to-host mail transport protocol that operates over
TCP, port 25.
SNMP
Simple Network Management Protocol. The application protocol in the Internet suite of protocols
which offers network management services.
SNTP
Simple Network Time Protocol
allows a device to set its internal clock based on periodic updates
from a Network Time Protocol (NTP) server. Updates can be requested from a specific NTP server,
or can be received via broadcasts sent by NTP servers.
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.
TACACS+
Terminal Access Controller Access Control System Plus. TA
CACS+
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.
TFTP
Trivial File Transfer Protocol. A TCP/IP protocol commonly used for software downloads.
UDP
User Datagram Protocol. UD
P
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.
