242APPENDIX F: GLOSSARY
Remote | RADIUS is a logon authentication protocol that uses software running |
Authentication | on a central server to control access to |
the network. | |
(RADIUS) |
|
Remote Monitoring | RMON provides comprehensive network monitoring capabilities. It |
(RMON) | eliminates the polling required in standard SNMP, and can set alarms on |
| a variety of traffic conditions, including specific error types. |
Rapid Spanning Tree | RSTP reduces the convergence time for network topology changes to |
Protocol (RSTP) | 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. |
Routing Information | The RIP protocol seeks to find the shortest route to another device by |
Protocol (RIP) | minimizing the |
| estimate of transmission cost. |
| adds useful capabilities for subnet routing, authentication, and |
| multicast transmissions. |
Simple Network | The application protocol in the Internet suite of protocols which offers |
Management | network management services. |
Protocol (SNMP) |
|
Spanning Tree | A technology that checks your network for any loops. A loop can often |
Protocol (STP) | 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 | TACACS+ is a logon authentication protocol that uses software running |
Controller Access | on a central server to control access to |
Control System Plus | the network. |
(TACACS+) | Transmission Control Protocol/Internet Protocol (TCP/IP) |
| |
| Protocol suite that includes TCP as the primary transport protocol, and |
| IP as the network layer protocol. |
Trivial File Transfer | A TCP/IP protocol commonly used for software downloads. |
Protocol (TFTP) |
|
User Datagram | UDP provides a datagram mode for |
Protocol (UDP) | uses IP as the underlying transport mechanism to provide access to |
