Glossary
Remote Authentication Dial-in User Service (RADIUS)
is a logon authentication protocol that uses software running on a central
RADIUS
server to control access to RADIUS-compliant devices on the network.
Remote Monitoring (RMON)
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.
Rapid Spanning Tree Protocol (RSTP)
reduces the convergence time for network topology changes to about 10% of
RSTP
that required by the older IEEE 802.1D STP standard.
Secure Shell (SSH)
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.
Simple Mail Transfer Protocol (SMTP)
A standard host-to-host mail transport protocol that operates over TCP, port 25.
Simple Network Management Protocol (SNMP)
The application protocol in the Internet suite of protocols which offers network
management services.
Simple Network Time Protocol (SNTP)
allows a device to set its internal clock based on periodic updates from a
SNTP
Network Time Protocol (NTP) server. Updates can be requested from a specific NTP
server, or can be received via broadcasts sent by NTP servers.
Spanning Tree Protocol (STP)
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 (TACACS+)
is a logon authentication protocol that uses software running on a central
TACACS+
server to control access to TACACS-compliant devices on the network.
Telnet
Defines a remote communication facility for interfacing to a terminal device over
TCP/IP.
