Quality of Service
(QoS)
QoS refers to the capability of a network to provide better service to selected traffic
flows using features such as data prioritization, queuing, congestion avoidance and
traffic shaping. These features effectively provide preferential treatment to specific
flows either by raising the priority of one flow or limiting the priority of another flow.
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.
Routing Information Protocol
(RIP)
The RIP protocol seeks to find the shortest route to another device by minimizing the
distance-vector, or hop count, which serves as a rough estimate of transmission
cost. RIP-2 is a compatible upgrade to RIP. It adds useful capabilities for subnet
routing, authentication, and multicast transmissions.
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.
