Page 69: Bridge Settings
Chapter 5: Configuration STP - STP uses a distributed algorithm to select a bridging device (STP- compliant switch, bridge, or router) that serves as the root of the spanning tree network. It selects a root port on each bridging device (except for the root device) which incurs the lowest path cost when forwarding a packet from that device to the root device.

Page 231: Appendix A. Glossary Of Web-Based Management
Appendix A: Glossary of Web-based Management Appendix A. Glossary of Web-based Management ACE—ACE is an acronym for Access Control Entry. It describes access permission associated with a particular ACE ID. There are three ACE frame types (Ethernet Type, ARP, and IPv4) and two ACE actions (permit and deny). The ACE also contains many detailed, different parameter options that are available for individual applications.
Page 232 Appendix A: Glossary of Web-based Management ARP Inspection—ARP Inspection is a secure feature. Several types of attacks can be launched against a host or devices connected to Layer 2 networks by “poisoning” the ARP caches. This feature is used to block such attacks. Only valid ARP requests and responses can go through the switch device.
Page 233 Appendix A: Glossary of Web-based Management DoS—DoS is an acronym for Denial of Service. In a denial-of-service (DoS) attack, an attacker attempts to prevent legitimate users from accessing information or services. By targeting at network sites or network connection, an attacker may be able to prevent network users from accessing email, web sites, online accounts (banking, etc.), or other services that rely on the affected computer.
Page 234 Appendix A: Glossary of Web-based Management HTTPS—HTTPS is an acronym for Hypertext Transfer Protocol over Secure Socket Layer. It is used to indicate a secure HTTP connection. HTTPS provide authentication and encrypted communication and is widely used on the World Wide Web for security-sensitive communication such as payment transactions and corporate logons.
Page 235 Appendix A: Glossary of Web-based Management LLC—The IEEE 802.2 Logical Link Control (LLC) protocol provides a link mechanism for upper layer protocols. It is the upper sub-layer of the Data Link Layer and provides multiplexing mechanisms that make it possible for several network protocols (IP, IPX) to coexist within a multipoint network.
Page 236 Appendix A: Glossary of Web-based Management NetBIOS—NetBIOS is an acronym for Network Basic Input/Output System. It is a program that allows applications on separate computers to communicate within a Local Area Network (LAN), and it is not supported on a Wide Area Network (WAN). The NetBIOS giving each computer in the network both a NetBIOS name and an IP address corresponding to a different host name, provides the session and transport services described in the Open Systems Interconnection (OSI) model.
Page 237 Appendix A: Glossary of Web-based Management POP3—POP3 is an acronym for Post Office Protocol version 3. It is a protocol for email clients to retrieve email messages from a mail server. POP3 is designed to delete mail on the server as soon as the user has downloaded it. However, some implementations allow users or an administrator to specify that mail be saved for some period of time.
Page 238 Appendix A: Glossary of Web-based Management RSTP—In 1998, the IEEE with document 802.1w introduced an evolution of STP: the Rapid Spanning Tree Protocol, which provides for faster spanning tree convergence after a topology change. Standard IEEE 802.1D-2004 now incorporates RSTP and obsoletes STP, while at the same time being backwards-compatible with STP.
Page 239 Appendix A: Glossary of Web-based Management Tag Priority—Tag Priority is a 3-bit field storing the priority level for the 802.1Q frame. TCP—TCP is an acronym for Transmission Control Protocol. It is a communications protocol that uses the Internet Protocol (IP) to exchange the messages between computers.
