RIP

Routing Information 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.

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. TA

CACS+

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.
