Page 80: Chapter 7 Spanning Tree
Chapter 7 Spanning Tree STP (Spanning Tree Protocol), subject to IEEE 802.1D standard, is to disbranch a ring network in the Data Link layer in a local network. Devices running STP discover loops in the network and block ports by exchanging information, in that way, a ring network can be disbranched to form a tree-topological ring-free network to prevent packets from being duplicated and forwarded endlessly in the network.
Page 81 Port: Port 3 is the root port of switch B and port 5 is the root port of switch C; port 1 is the  designated port of switch A and port 4 is the designated port of switch B; port 6 is the blocked port of switch C.
Page 82 STP Generation  In the beginning  In the beginning, each switch regards itself as the root, and generates a configuration BPDU for each port on it as a root, with the root path cost being 0, the ID of the designated bridge being that of the switch, and the designated port being itself.
Page 83 Tips： In an STP with stable topology, only the root port and designated port can forward data, and the other ports are blocked. The blocked ports only can receive BPDUs. RSTP (Rapid Spanning Tree Protocol), evolved from the 802.1D STP standard, enable Ethernet ports to transit their states rapidly.
Page 84 Figure 7-2 Basic MSTP diagram MSTP  MSTP divides a network into several MST regions. The CST is generated between these MST regions, and multiple spanning trees can be generated in each MST region. Each spanning tree is called an instance. As well as STP, MSTP uses BPDUs to generate spanning tree. The only difference is that the BPDU for MSTP carries the MSTP configuration information on the switches.
Page 85: Stp Config
Figure 7-3 Port roles The Spanning Tree module is mainly for spanning tree configuration of the switch, including four submenus: STP Config, Port Config, MSTP Instance and STP Security. 7.1 STP Config The STP Config function, for global configuration of spanning trees on the switch, can be implemented on STP Config and STP Summary pages.

Page 102: Chapter 8 Multicast
Chapter 8 Multicast Multicast Overview  In the network, packets are sent in three modes: unicast, broadcast and multicast. In unicast, the source server sends separate copy information to each receiver. When a large number of users require this information, the server must send many pieces of information with the same content to the users.
Page 103 Multicast Address  1. Multicast IP Address: As specified by IANA (Internet Assigned Numbers Authority), Class D IP addresses are used as destination addresses of multicast packets. The multicast IP addresses range from 224.0.0.0~239.255.255.255. The following table displays the range and description of several special multicast IP addresses.

Page 160: Arp Inspection
11.2 ARP Inspection According to the ARP Implementation Procedure stated in 11.1.3 ARP Scanning, it can be found that ARP protocol can facilitate the Hosts in the same network segment to communicate with one another or access to external network via Gateway. However, since ARP protocol is implemented with the premise that all the Hosts and Gateways are trusted, there are high security risks during ARP Implementation Procedure in the actual complex network.
Page 161 Figure 11-10 ARP Attack – Cheating Gateway As the above figure shown, the attacker sends the fake ARP packets of Host A to the Gateway, and then the Gateway will automatically update its ARP table after receiving the ARP packets. When the Gateway tries to communicate with Host A in LAN, it will encapsulate this false destination MAC address for packets, which results in a breakdown of the normal communication.
Page 162 Figure 11-11 ARP Attack – Cheating Terminal Hosts As the above figure shown, the attacker sends the fake ARP packets of Host A to Host B, and then Host B will automatically update its ARP table after receiving the ARP packets. When Host B tries to communicate with Host A, it will encapsulate this false destination MAC address for packets, which results in a breakdown of the normal communication.
Page 163 Figure 11-12 Man-In-The-Middle Attack Suppose there are three Hosts in LAN connected with one another through a switch. Host A: IP address is 192.168.0.101; MAC address is 00-00-00-11-11-11. Host B: IP address is 192.168.0.102; MAC address is 00-00-00-22-22-22. Attacker: IP address is 192.168.0.103; MAC address is 00-00-00-33-33-33. First, the attacker sends the false ARP response packets.
Page 164: Arp Detect
The IP-MAC Binding function allows the switch to bind the IP address, MAC address, VLAN ID and the connected Port number of the Host together when the Host connects to the switch. Basing on the predefined IP-MAC Binding entries, the ARP Inspection functions to detect the ARP packets and filter the illegal ARP packet so as to prevent the network from ARP attacks.

Page 170 An 802.1X authentication is initiated when a user launches client program on the supplicant system. Note that the client program must support the 802.1X authentication protocol. （2） Authenticator System: The authenticator system is usually an 802.1X-supported network device, such as this TP-LINK switch. It provides the physical or logical port for the supplicant system to access the LAN and authenticates the supplicant system.
Page 171 Figure 11-18 EAP-MD5 Authentication Procedure A supplicant system launches an 802.1X client program via its registered user name and password to initiate an access request through the sending of an EAPOL-Start packet to the switch. The 802.1X client program then forwards the packet to the switch to start the authentication process.
Page 172 The supplicant system can also terminate the authenticated state by sending EAPOL-Logoff packets to the switch. The switch then changes the port state from accepted to rejected. （2） EAP Terminating Mode In this mode, packet transmission is terminated at authenticator systems and the EAP packets are mapped into RADIUS packets.

Page 194: Chapter 13 Lldp
Chapter 13 LLDP LLDP (Link Layer Discovery Protocol) is a Layer 2 protocol that is used for network devices to advertise their own device information periodically to neighbors on the same IEEE 802 local area network. The advertised information, including details such as device identification, capabilities and configuration settings, is represented in TLV (Type/Length/Value) format according to the IEEE 802.1ab standard, and these TLVs are encapsulated in LLDPDU (Link Layer Discovery Protocol Data Unit).
Page 195  Disable: the port cannot transmit or receive LLDPDUs. LLDPDU transmission mechanism  If the ports are working in TxRx or Tx mode, they will advertise local information by sending LLDPDUs periodically.  If there is a change in the local device, the change notification will be advertised. To prevent a series of successive LLDPDUs transmissions during a short period due to frequent changes in local device, a transmission delay timer is set by network management to ensure that there is a defined minimum time between successive LLDP...
Page 196 TLV Type TLV Name Description Usage in LLDPDU Time To Live Indicates the number of seconds that the Mandatory neighbor device is to regard the local information to be valid. Port Description Identifies the description string of the port. Optional System Name Identifies the system name.
Page 197: Basic Config
System Name TLV The System Name TLV allows network management to advertise the system's assigned name, which should be the system's fully qualified domain name.
