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.
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.
T
ELNET
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.
