Figure 4-6 Daylight Saving Time The following entries are displayed on this screen: DST Config DST Status: Enable or disable the DST. Predefined Mode: Select a predefined DST configuration: Recurring Mode: USA: Second Sunday in March, 02:00 ~ First Sunday in November, 02:00. Australia: First Sunday in October, 02:00 ~ First Sunday in April, 03:00.
Note: 1. When the DST is disabled, the predefined mode, recurring mode and date mode cannot be configured. 2. When the DST is enabled, the default daylight saving time is of Europe in predefined mode. 4.1.5 System IP Each device in the network possesses a unique IP Address. You can log on to the Web management page to operate the switch using this IP Address. The switch supports three modes to obtain an IP address: Static IP, DHCP and BOOTP.
3. If the switch gets the IP address from DHCP server, you can see the configuration of the switch in the DHCP server; if DHCP option is selected but no DHCP server exists in the network, a few minutes later, the switch will restore the setting to the default. 4. If DHCP or BOOTP option is selected, the switch will get network parameters dynamically from the Internet, which means that its IP address, subnet mask and default gateway cannot be configured. 5. By default, the default IP address is 192.168.
6. Enhanced neighbor discovery mechanism: The IPv6 neighbor discovery protocol is a group of Internet control message protocol version 6 (ICMPv6) messages that manages the information exchange between neighbor nodes on the same link. The group of ICMPv6 messages takes the place of Address Resolution Protocol (ARP) message, Internet Control Message Protocol version 4 (ICMPv4) router discovery message, and ICMPv4 redirection message to provide a series of other functions. Introduction to IPv6 address 1.
Multicast address: An identifier for a set of interfaces (typically belonging to different nodes), similar to an IPv4 multicast address. A packet sent to a multicast address is delivered to all interfaces identified by that address. There are no broadcast addresses in IPv6. Their function is superseded by multicast addresses. Anycast address: An identifier for a set of interfaces (typically belonging to different nodes).
For all IEEE 802 interface types (for example, Ethernet and FDDI interfaces), Interface IDs in the modified EUI-64 format are constructed in the following way: The first three octets (24 bits) are taken from the Organizationally Unique Identifier (OUI) of the 48-bit link-layer address (the MAC address) of the interface, the fourth and fifth octets (16 bits) are a fixed hexadecimal value of FFFE, and the last three octets (24 bits) are taken from the last three octets of the MAC address.
Figure 4-9 Link-local Address Format IPv6 devices must not forward packets that have link-local source or destination addresses to other links. Note: You can configure multiple IPv6 addresses per interface, but only one link-local address.
Neighbor Reachability Detection After node A acquires the link-layer address of its neighbor node B, node A can verify whether node B is reachable according to NS and NA messages. Node A sends an NS message whose destination address is the IPv6 address of node B. If node A receives an NA message from node B, node A considers that node B is reachable. Otherwise, node B is unreachable.
RAs are also sent in response to device solicitation messages. Device solicitation messages, which have a value of 133 in the Type field of the ICMP packet header, are sent by hosts at system startup or anytime needed so that the host can immediately autoconfigure without needing to wait for the next scheduled RA message. Hosts discover and select default devices by listening to Router Advertisements (RAs).
You can configure the system’s administrative IPv6 address on this page. Choose the menu System →System Info →System IPv6 to load the following page. Figure 4-10 System IPv6 The following entries are displayed on this screen: Global Config IPv6: Enable/Disable IPv6 function globally on the switch.

the data of specific protocol can be automatically assigned to the corresponding VLAN for transmission. The network administrator can manage network clients based on their specific applications and services through protocol VLAN. Encapsulation Format of Ethernet Data This section simply introduces the common used encapsulation format of Ethernet data to understand the procedure for the switch to identify the protocol of packets.
The Procedure for the Switch to Identify Packet Protocol The Implementation of Protocol VLAN This switch can match packets through protocol template and transmit packets in the specific VLAN according to the protocol. Protocol template, comprising encapsulation format and protocol type, is the standard to determine the protocol which a packet belongs to. The following table shows the common used encapsulation formats supported in network layer protocol and the protocol templates are for reference.
The packet in Protocol VLAN is processed in the following way: VLAN packets are processed in the following way: 1. When receiving an untagged packet, the switch matches the packet with the current Protocol VLAN. If the packet is matched, the switch will add a corresponding Protocol VLAN tag to it. If no Protocol VLAN is matched, the switch will add a tag to the packet according to the PVID of the received port. Thus, the packet is assigned automatically to the corresponding VLAN for transmission. 2.

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. BPDU (Bridge Protocol Data Unit) is the protocol data that STP and RSTP use.
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. Forward Delay: Forward Delay ranges from 4 to 30 seconds. It specifies the time for the port to transit its state after the network topology is changed.
Comparing BPDUs Each switch sends out configuration BPDUs and receives a configuration BPDU on one of its ports from another switch. The following table shows the comparing operations. Step Operation 1 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.
The condition for the root port to transit its port state rapidly: The old root port of the switch stops forwarding data and the designated port of the upstream switch begins to forward data. The condition for the designated port to transit its port state rapidly: The designated port is an edge port or connecting to a point-to-point link.
The following figure shows the network diagram in MSTP. 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.
The following diagram shows the different port roles. 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. 7.1.

Max Hops: Enter a value from 1 to 40 to set the maximum number of hops that occur in a specific region before the BPDU is discarded. The default value is 20 hops. Note: 1. The forward delay parameter and the network diameter are correlated. A too small forward delay parameter may result in temporary loops. A too large forward delay may cause a network unable to resume the normal state in time. The default value is recommended. 2.

7.4 STP Security Configuring protection function for devices can prevent devices from any malicious attack against STP features. The STP Security function can be implemented on Port Protect and TC Protect pages. Port Protect function is to prevent the devices from any malicious attack against STP features. 7.4.1 Port Protect On this page you can configure loop protect feature, root protect feature, TC protect feature, BPDU protect feature and BPDU filter feature for ports.
Normally these ports do not receive BPDUs, but if a user maliciously attacks the switch by sending BPDUs, network topology jitter occurs. To prevent this attack, MSTP provides BPDU protect function. With this function enabled on the switch, the switch shuts down the edge ports that receive BPDUs and reports these cases to the administrator. If a port is shut down, only the administrator can restore it. BPDU Filter BPDU filter function is to prevent BPDUs flood in the STP network.
Port: Displays the port number of the switch. Loop Protect: Loop Protect is to prevent the loops in the network brought by recalculating STP because of link failures and network congestions. Root Protect: Root Protect is to prevent wrong network topology change caused by the role change of the current legal root bridge.

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. Therefore, large bandwidth will be occupied. In broadcast, the system transmits information to all users in a network.
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. Multicast IP address range Description 224.0.0.0~224.0.0.255 Reserved multicast addresses for routing protocols and other network protocols 224.0.1.
0XFF at the start of the address identifies the address as being a multicast address. Flags have 4 bits: (1) The high-order flag is reserved, and must be initialized to 0. (2) R: Set to 0 to indicate this IPv6 multicast address does not contain an embedded RP address; set to 1 to indicate this IPv6 multicast address contains an embedded RP address. When this bit is set to 1, the P and T bits must also be set to 1.
Reserved Multicast Addresses: Address Indication FF01::1 All interface-local IPv6 nodes FF02::1 All link-local IPv6 nodes FF01::2 All interface-local IPv6 routers FF02::2 All link-local IPv6 routers FF05::2 All site-local IPv6 routers FF0X:: X ranges from 0 to F. These multicast addresses are reserved and shall never be assigned to any multicast group.
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. The multicast address table is not mapped to an egress port but a group port list.
if the multicast groups contain any member. When receiving IGMP leave message, the receiving port of the router will send IGMP group-specific-query message to the multicast group and the switch will forward IGMP group-specific-query message to check if other members in the multicast group of the port need this multicast. When receiving IGMP general query message, the switch will forward them to all other ports in the VLAN owning the receiving port.
The IGMP Snooping function can be implemented on the following pages: Snooping Config, VLAN Config, Port Config, IP-Range, Multicast VLAN, Static Multicast IP and Packet Statistics. 8.1.1 Snooping Config To configure the IGMP Snooping on the switch, please firstly configure IGMP global configuration and related parameters on this page.

Chapter 9 QoS QoS (Quality of Service) functions to provide different quality of service for various network applications and requirements and optimize the bandwidth resource distribution so as to provide a network service experience of a better quality. QoS This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets according to specified scheduling algorithms to implement QoS function.
2. 802.1P Priority Figure 9-2 802.1Q frame As shown in the figure above, each 802.1Q Tag has a Pri field, comprising 3 bits. The 3-bit priority field is 802.1p priority in the range of 0 to 7. 802.1P priority determines the priority of the packets based on the Pri value. On the Web management page of the switch, you can configure different priority tags mapping to the corresponding priority levels, and then the switch determine which packet is sent preferentially when forwarding packets.
Figure 9-4 SP-Mode 2. WRR-Mode: Weight Round Robin Mode. In this mode, packets in all the queues are sent in order based on the weight value for each queue and every queue can be assured of a certain service time. The weight value indicates the occupied proportion of the resource. WRR queue overcomes the disadvantage of SP queue that the packets in the queues with lower priority cannot get service for a long time.
The QoS module is mainly for traffic control and priority configuration, including three submenus: DiffServ, Bandwidth Control and Voice VLAN. 9.1 DiffServ This switch classifies the ingress packets, maps the packets to different priority queues and then forwards the packets according to specified scheduling algorithms to implement QoS function. This switch implements three priority modes basing on port, on 802.1P and on DSCP, and supports four queue scheduling algorithms.
Configuration Procedure: Step Operation Description 1 Select the port priority Required. On QoS→DiffServ→Port Priority page, configure the port priority. 2 Configure the relation between priority and TC Required. On QoS→DiffServ→802.1P/CoS mapping page, configure the mapping relation between the CoS and TC. 3 Select a schedule mode mapping the CoS Required.

network configuration protocol optimized and developed based on the BOOTP, functions to solve the above mentioned problems. DHCP Working Principle DHCP works via the “Client/Server” communication mode. The Client applies to the Server for configuration. The Server assigns the configuration information, such as the IP address, to the Client, so as to reach a dynamic employ of the network source. A Server can assign the IP address for several Clients, which is illustrated in the following figure.
The most Clients obtain the IP addresses dynamically, which is illustrated in the following figure. Figure 12-6 Interaction between a DHCP client and a DHCP server (1) DHCP-DISCOVER Stage: The Client broadcasts the DHCP-DISCOVER packet to find the DHCP Server.
supported Option 82 also can set the distribution policy of IP addresses and the other parameters according to the Option 82, providing more flexible address distribution way. Option 82 can contain 255 sub-options at most. If Option 82 is defined, at least a sub-option should be defined. This switch supports two sub-options: Circuit ID and Remote ID. Since there is no universal standard about the content of Option 82, different manufacturers define the sub-options of Option 82 to their need.
DHCP Snooping feature prevents the network from the DHCP Server Cheating Attack by discarding the DHCP packets on the distrusted port, so as to enhance the network security. Choose the menu Network Security→IP-MAC Binding→DHCP Snooping to load the following page.

Figure 12-10 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.
Figure 12-11 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.
Figure 12-12 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. 1. First, the attacker sends the false ARP response packets. 2. Upon receiving the ARP response packets, Host A and Host B updates the ARP table of their own. 3.
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. Based 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. The ARP Inspection function is implemented on the ARP Detect, ARP Defend and ARP Statistics pages. 12.2.
