Remote Authentication Dial-in User Service (RADIUS)
RADIUS
is a logon authentication protocol that uses software running on a central 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)
RSTP reduces the convergence time for network topology changes to about 10% of 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)
SNTP
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.
Spanning Tree Algorithm (STA)
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.
Telnet
Defines a remote communication facility for interfacing to a terminal device over TCP/IP.
Terminal Access Controller Access Control System Plus (TACACS+)
TACACS+ is a logon authentication protocol that uses software running on a central
server to control access to TACACS-compliant devices on the network.
