SNMP, and can set alarms on a variety of traffic conditions, including
specific error types.
RSTP Rapid Spanning Tree Protocol. RSTP reduces the convergence time
for network topology changes to about 10% of that required by the
older IEEE 802.1D STP standard.
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. 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.
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
