Chapter 6 VLAN The traditional Ethernet is a data network communication technology basing on CSMA/CD (Carrier Sense Multiple Access/Collision Detect) via shared communication medium. Through the traditional Ethernet, the overfull hosts in LAN will result in serious collision, flooding broadcasts, poor performance or even breakdown of the Internet.
Page 59: Q Vlan
6.1 802.1Q VLAN VLAN tags in the packets are necessary for the switch to identify packets of different VLANs. The switch works at the data link layer in OSI model and it can identify the data link layer encapsulation of the packet only, so you can add the VLAN tag field into the data link layer encapsulation for identification.
Page 60: Vlan Config
PVID  PVID (Port Vlan ID) is the default VID of the port. When the switch receives an un-VLAN-tagged packet, it will add a VLAN tag to the packet according to the PVID of its received port and forward the packets. When creating VLANs, the PVID of each port, indicating the default VLAN to which the port belongs, is an important parameter with the following two purposes: （1）...

For the steps of creating VLAN, please refer to 802.1Q VLAN. 6.8 GVRP GVRP (GARP VLAN Registration Protocol) is an implementation of GARP (generic attribute registration protocol). GVRP allows the switch to automatically add or remove the VLANs via the dynamic VLAN registration information and propagate the local VLAN registration information to other switches, without having to individually configure each VLAN.
Page 79  LeaveAll Timer: Once a GARP entity starts up, it starts the LeaveAll timer, and sends out a LeaveAll message after the timer times out, so that other GARP entities can re-register all the attribute information on this entity. After that, the entity restarts the LeaveAll timer to begin a new cycle.

Page 81: Private Vlan
LeaveAll Timer: Once the LeaveAll Timer is set, the port with GVRP enabled can send a LeaveAll message after the timer times out, so that other GARP ports can re-register all the attribute information. After that, the LeaveAll timer will start to begin a new cycle. The LeaveAll Timer ranges from 1000 to 30000 centiseconds.
Page 82 Private VLAN technology is mainly used in campus or enterprise networks to achieve user layer-2-separation and to save VLAN resources of uplink devices.  The Elements of a Private VLAN Primary VLAN: A Private VLAN has one Primary VLAN and one Secondary VLAN. Primary VLAN is the user VLAN uplink device can identify but it is not the actual VLAN the end user is in.
Page 83 2) Port configuration and MAC address duplication should be synchronized on the switch. Port configuration synchronization is completed in the whole configuration progress and MAC address duplication is implemented while FDB is changing.  Port configuration synchronization: when configuring promiscuous and host ports for a Private VLAN, the system will automatically add the promiscuous port and the host port synchronously to the corresponding Primary VLAN and Secondary VLAN.
Page 84  MAC address duplication: After port configuration synchronization, packets from Secondary VLAN can be forwarded via the promiscuous port untagged, and those from Primary VLAN can be sent via the host port untagged. In order for these packets can be forwarded in unicast via the right port, MAC address duplication is used to expand the VLANs the MAC address is in.
Page 85: Pvlan Config
The Private VLAN packet forwarding process (here we take traffic transmission for PC2) based on the figure above is illustrated as follows: PC2 sends out its first upstream packet with the source MAC as mac_2 and the destination MAC as mac_a. This packet is untagged. When the host port Port2 on the switch receives this packet, it adds a default VLAN ID 2 to this packet and learns its source MAC address.

Page 90: 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 91 Figure 7-1 Basic STP diagram STP Timers  Hello Time: Hello Time ranges from 1 to 10 seconds. It specifies the interval to send BPDU packets. It is used to test the links. Max. Age: Max. Age ranges from 6 to 40 seconds. It specifies the maximum time the switch can wait without receiving a BPDU before attempting to reconfigure.
Page 92 Step Operation If the priority of the BPDU received on the port is lower than that of the BPDU if of the port itself, the switch discards the BPDU and does not change the BPDU of the port. If the priority of the BPDU is higher than that of the BPDU of the port itself, the switch replaces the BPDU of the port with the received one and compares it with those of other ports on the switch to obtain the one with the highest priority.

Page 103 Loop Protect  In a stable network, a switch maintains the states of ports by receiving and processing BPDU packets from the upstream switch. However, when link congestions or link failures occurred to the network, a down stream switch does not receive BPDU packets for certain period, which results in spanning trees being regenerated and roles of ports being reselected, and causes the blocked ports to transit to forwarding state.
Page 104 With BPDU filter function enabled, a port does not receive or forward BPDUs, but it sends out its own BPDUs. Such a mechanism prevents the switch from being attacked by BPDUs so as to guarantee generation the spanning trees correct.

Page 109: 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 110 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 111: Igmp Snooping
IGMP Snooping  In the network, the hosts apply to the near Router for joining (leaving) a multicast group by sending IGMP (Internet Group Management Protocol) messages. When the up-stream device forwards down the multicast data, the switch is responsible for sending them to the hosts. IGMP Snooping is a multicast control mechanism, which can be used on the switch for dynamic registration of the multicast group.
Page 112: Snooping Config
3. IGMP Leave Message The host, running IGMPv1, does not send IGMP leave message when leaving a multicast group, as a result, the switch can not get the leave information of the host momentarily. However, after leaving the multicast group, the host does not send IGMP report message any more, so the switch will remove the port from the corresponding multicast address table when its member port time times out.

A Server can assign the IP address for several Clients, which is illustrated in the following figure.
Page 162 （2） DHCP-OFFER Stage: Upon receiving the DHCP-DISCOVER packet, the DHCP Server selects an IP address from the IP pool according to the assigning priority of the IP addresses and replies to the Client with DHCP-OFFER packet carrying the IP address and other information.
Page 163 Figure 11-7 DHCP Cheating Attack Implementation Procedure DHCP Snooping feature only allows the port connected to the DHCP Server as the trusted port to forward DHCP packets and thereby ensures that users get proper IP addresses. DHCP Snooping is to monitor the process of the Host obtaining the IP address from DHCP server, and record the IP address, MAC address, VLAN and the connected Port number of the Host for automatic binding.

Page 167 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 168 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 169: Arp Detect
ARP Flooding Attack  The attacker broadcasts a mass of various fake ARP packets in a network segment to occupy the network bandwidth viciously, which results in a dramatic slowdown of network speed. Meantime, the Gateway learns the false IP address-to-MAC address mapping entries from these ARP packets and updates its ARP table.

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 178 can also launch an 802.1X client program to initiate an 802.1X authentication through the sending of an EAPOL-Start packet to the switch, This TP-LINK switch can authenticate supplicant systems in EAP relay mode or EAP terminating mode. The following illustration of these two modes will take the 802.1X authentication procedure initiated by the supplicant system for example.
Page 179 The RADIUS server compares the received encrypted password (contained in a RADIUS Access-Request packet) with the locally-encrypted password. If the two match, it will then send feedbacks (through a RADIUS Access-Accept packet and an EAP-Success packet) to the switch to indicate that the supplicant system is authorized. The switch changes the state of the corresponding port to accepted state to allow the supplicant system access the network.
