Page 94: 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 115: 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 116 IPv4 Multicast Address  1. IPv4 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.

The high-order 16 bits of the IP multicast address are 0x3333, identifying the IPv6 multicast group. The low-order 32 bits of the IPv6 multicast IP address are mapped to the multicast MAC address. Multicast Address Table  The switch is forwarding multicast packets based on the multicast address table. As the transmission of multicast packets cannot span the VLAN, the first part of the multicast address table is VLAN ID, based on which the received multicast packets are forwarded in the VLAN owning the receiving port.
Page 120 IGMP Messages  The switch, running IGMP snooping, processes the IGMP messages of different types as follows. 1. IGMP Query Message IGMP query message, sent by the router, falls into two types, IGMP general query message and IGMP group-specific-query message. The router regularly sends IGMP general message to query if the multicast groups contain any member.
Page 121: Snooping Config
2. Timers Router Port Time: Within the time, if the switch does not receive IGMP query message from the router port, it will consider this port is not a router port any more. The default value is 300 seconds. Member Port Time: Within the time, if the switch does not receive IGMP report message from the member port, it will consider this port is not a member port any more.

Page 207 Cheating Gateway  The attacker sends the wrong IP address-to-MAC address mapping entries of Hosts to the Gateway, which causes that the Gateway cannot communicate with the legal terminal Hosts normally. The ARP Attack implemented by cheating Gateway is illustrated in the following figure. Figure 13-11 ARP Attack –...
Page 208 Figure 13-12 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 209 Figure 13-13 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.

The supplicant system is usually a common user terminal computer. An 802.1X authentication is initiated when a user launches client program on the supplicant system.
Page 217 EAP Relay Mode This mode is defined in 802.1X. In this mode, EAP-packets are encapsulated in higher level protocol (such as EAPOR) packets to allow them successfully reach the authentication server. This mode normally requires the RADIUS server to support the two fields of EAP: the EAP-message field and the Message-authenticator field.
Page 218 The switch changes the state of the corresponding port to accepted state to allow the supplicant system access the network. And then the switch will monitor the status of supplicant by sending hand-shake packets periodically. By default, the switch will force the supplicant to log off if it cannot get the response from the supplicant for two times.
