RADIUS Remote Authentication Dial-in User Service. RADIUS is a logon
authentication protocol that uses software running on a central server to
control access to RADIUS-compliant devices on the network.
RMON Remote Monitoring. RMON provides comprehensive network monitoring
capabilities. It eliminates the polling required in standard 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.
