4 Configuration
4.1 VLAN
VLAN is formulated not restricted to physical locations, which means the hosts in a same VLAN can be placed at will. As shown below, each VLAN, as a broadcast domain, divides a physical LAN into logical LANs. Hosts can exchange messages by means of
10
traditional communication. For the hosts in different VLANs, the device such as router or L3 switch is a must.
VLAN is superior to the traditional Ethernet in terms of: Broadcast domain coverage: the broadcast message in a LAN is limited in a VLAN to
save the bandwidth and handle the network-related issues more efficiently. LAN security: VLAN hosts fail to communicate with each other since the messages
are separated by the broadcast domain in the data link layer. They need a router or a Layer 3 switch for Layer 3 forwarding. Flexibility of creating a virtual working team: VLAN can create a virtual working team beyond the control of physical network. Users have access to the network without changing the configuration if their physical locations are moving within the scope. This management switch is compatible with VLAN types based on 802.1Q, protocols, MAC, and ports. For default configuration, 802.1Q VLAN mode should be adopted. Port VLAN is divided subject to a switch’s interface No. Network administrator gives each switch interface a different PVID, namely a port default VLAN. If a data frame without a VLAN tag flows into a switch interface with a PVID, it will be marked with the same PVID, or it will get rid of an additional tag even though the interface has a PVID. The solution to a VLAN frame depends on the interface type, which eases member definition but re-configures VLAN in case of member mobility.

4.2 QOS
QoS (Quality of Service) assesses the ability of service providers to meet customer needs and the ability of transmitting packets over the Internet. Diversified services can be assessed based on different aspects. QoS usually refers to the evaluation of service capabilities that support core requirements such as bandwidth, delay, delay variation, and packet loss rate during delivery. Bandwidth, also known as throughput, refers to the average business flow within a certain period of time, with the unit of Kbit/s. Delay refers to the average time required for business flowing through the network. For a network device, the followings are general levels of delay requirements. There are two delay levels, that is, the high-priority business can be served as soon as possible by scheduling method of priority queue, while the low-priority business gets services after that. Delay variation refers to the time change of business flowing through the network. Packet loss rate refers to the percentage of lost business flow during transmission. As modern transmission systems are very reliable, information is often lost in network congestion. Packet loss due to queue overflow is the most common situation.
All messages in a traditional IP network are treated equally. Every network device processes the messages on a FIFO basis, and makes every effort to transmit them to destinations without guaranteeing reliability, transfer delay, or other performance.
Network service quality is constantly improved as new applications keep springing up in the rapidly changing IP network. For example, VoIP, video and other delay-sensitive services have set higher standards on message transmission delay. Message transmission in a short period has been the common trend. In order to support voice, video and data services with different requirements, the network needs to identify business types and provide corresponding services.
The ability to distinguish business types is the prerequisite to provide corresponding services, so the traditional best-effort service no longer meets the application needs. Therefore, QoS comes into being. It regulates the network flow to avoid and handle network congestion and reduce packet loss rate. Meanwhile, users can enjoy dedicated bandwidths while business can improve service quality, thus perfecting the network service capacity.
QoS priorities vary with message types. For instance, the VLAN message uses 802.1p, also known as the CoS (Class of Service) field, while the IP message uses DSCP. To maintain the priority, these fields need to be mapped at the gateway connected with various networks when messages flow through the network. 802.1p priority in the VLAN frame header
Typically, VLAN frames are interacted between Layer 2 devices. The PRI field (i.e. 802.1p priority), or CoS field, in the VLAN frame header identifies the quality of service requirements according to the definitions in IEEE 802.1Q. 802.1p priority in the VLAN frame
13
The 802.1Q header contains 3-bit PRI fields. PRI field defines 8 CoS of business priority ranging from 7 to 0 from high to low. IP Precedence/DSCP Field
According to RFC791 definition, ToS (Type of Service) domain in the IP message header is composed of 8 bits. Among them, the 3-bit long Precedence field, as located in the following, identifies the IP message priority. IP Precedence/DSCP Field
0 to 2 bits are Precedence fields representing the 8 priorities of message transmission ranging from 7 to 0 from high to low, with either Level 7 or 6 as the highest priority that is generally reserved for routing or updating network control communication. User-level applications only have access to Level 0 to 5.
ToS domain, in addition to Precedence fields, also includes D, T and R bits: D-bit represents the Delay requirement (0 for normal delay and 1 for low delay). T-bit represents the throughput (0 for normal throughput and 1 for high throughput). R-bit represents the reliability (0 for normal reliability and 1 for high reliability). ToS domain reserves the 6 and 7 bits.
RFC1349 redefines the ToS domain by adding a C-bit to represent the Monetary Cost. The IETF DiffServ group then redefines the 0 to 5 bits of ToS domain in the IPv4 message header of RFC2474 as DSCP and renames it as DS (Differentiated Service) byte as shown in the figure above.
The first 6 bits (0-5 bits) of DS field distinguish the DSCP (DS Code Point), and the higher 2 bits (6-7 bits) are reserved. The lower 3 bits (0-2 bits) are CSCP (Class Selector Code Point), with the same CSCP value representing the DSCP of the same class. DS nodes select corresponding PHB (Per-Hop Behavior) according to DSCP values.

4.3 Loop
4.3.1 Loop detection/loop prevention
The device sends loop detection packets and checks whether the packets are returned to the device (the receiving and sending interfaces are not required to be the same) to check whether loops exist. If a port receives a loop detection packet from the local device, it is determined that the link to which the port resides has a loop. When a loop occurs on the network, the LED of the corresponding port blinks (blocking the loop when loop avoidance is enabled) to alert the network administrator that a loop exists on the port

4.3.2 STP global
Fast spanning tree protocol (RSTP) is used to eliminate the physical loop of data link layer in LAN. Its core is fast spanning tree algorithm. RSTP is fully downward compatible with STP protocol. In addition to the functions of avoiding loops and dynamically managing redundant links like the traditional STP protocol, RSTP greatly shortens the topology convergence time. Under the ideal network topology scale, all switching devices support RSTP protocol, and when configured properly, the time to restore stability after topology changes (link up / down) can be controlled at the second level. The main functions of RSTP can be summarized as follows

4.4 IGMP Snooping
IGMP Snooping (Internet Group Management Protocol Snooping) is a constraint mechanism on L2 devices to manage and control multicast groups. By analyzing the IGMP messages received, L2 devices establish a mapping between ports and MAC multicast addresses and forward the multicast data accordingly. As shown below, multicast data are transmitted on L2 without IGMP snooping. When IGMP snooping runs, known multicast group data are transmitted to specified receivers while unknown multicast data are still on Layer 2.

4.5 Trunk Group Setting
4.5.1 static Link Aggregation broadens bandwidth and reliability by bundling a group of
physical interfaces into a single logical interface. LAG (Link Aggregation Group) is a logical link bundled by multiple Ethernet links (Eth-Trunk).
Ceaselessly expanding network size increases users’ demands of link bandwidth and reliability. Traditionally, high-speed interface board or the compatible equipment is usually replaced to optimize bandwidth, which is expensive and inflexible. Link Aggregation Technology bundles multiple physical interfaces into a single logical interface without upgrading hardware. Its backup mechanism not only improves reliability, but also shares the flow load on different physical links.
As shown below, Switch A is linked with Switch B through three Ethernet links which are bundled into an Eth-Trunk logical link. Its bandwidth equals to that of the three links in total, thus broadening the bandwidth. Meanwhile, these three links back up mutually to be more reliable.
When there are the following requirements, link aggregation can be configured to achieve: When the bandwidth between two switch devices connected through a link is
20
insufficient.
When the reliability of connecting two switch devices through a link does not meet the requirements.
Link aggregation is divided into static mode and LACP mode based on whether the Link Aggregation Control Protocol (LACP) is enabled or not. In static mode, the establishment of Eth Trunk and the addition of member interfaces are manually configured without the involvement of link aggregation control protocols. In this mode, all active links participate in data forwarding and evenly share traffic, hence it is called load sharing mode. If an active link fails, the link aggregation group automatically shares the traffic equally among the remaining active links. When it is necessary to provide a larger link bandwidth between two directly connected devices and the devices do not support the LACP protocol, static mode can be used.
Instructions: 1. Click the “Configuration > Trunk Group Setting”, in the navigation bar as follows:
Interface data are as follows
Configuration Items
Description
Group ID
There are 2 LAGs numbering from 1 to 2.
Ports
Up to 4 member ports are available in LAG.
4.5.2 LACP
LACP (Link Aggregation Control Protocol), based on IEEE 802.3ad Standard, dynamically aggregates and disaggregates links. It exchanges info with the opposite network devices through LACPDU (Link Aggregation Control Protocol Data Unit). After a port uses LACP, it will inform the opposite network device of system priority, system MAC, port priority and No., and operation Key by transmitting a LACPDU. The opposite device will compare such info with that saved by other ports after receiving it,
21
thus reaching an agreement on port participation in or quitting from a dynamic aggregation.
Dynamic LACP aggregation is automatically created or deleted by system, that is, internal ports can be added or removed by themselves. Only the ports connected to a same device with the same rate, duplex, and basic configuration can be aggregated. Instructions for adding a dynamic link aggregation:
1. Click the “Configuration > Trunk Group Setting” in the navigation bar, select the LAG ID and LACP mode, “Edit” them as follows:
2. Click the “Configuration > Trunk Group Setting” Select LACP, select two ports to add as one LACP group
Interface data are as follows

Type
Static mode: When it is necessary to increase the bandwidth or
reliability between two devices, and one of the devices does not
support the LACP protocol, a static link aggregation can be created
on the device and multiple member interfaces can be added to
increase the bandwidth and reliability between the devices.
System Priority
LACP mode: In dynamic LACP mode, the link between two devices has the ability of redundant backup. When some links fail, the backup link is used to replace the faulty link, maintaining uninterrupted data transmission.
LACP determines the active and passive modes between two devices subject to priority standard.

Please make sure there is no member interface accessing the Eth-Trunk before changing its work pattern, otherwise it fails.
4.6 Port-based Mirroring
Port Mirroring copies the message of a specified switch port to the destination port. The copied port is the Source Port, and the copying port is the Destination Port. Destination Port accesses to data inspection devices so that users can analyze the messages received to monitor network and troubleshoot as follows:

4.11 EEE
1. Click the “Configuration > EEE”, in the navigation bar as follows:
5 Security
5.1 MAC Address
Ethernet switches are mainly innovated to forward according to the purposes in the data link layer. That is, MAC address will transmit the messages to corresponding ports
26
according to the purposes. MAC address forwarding table is a L2 table illustrating MAC addresses and forwarding ports, which is the basis of fast forwarding of L2 messages. MAC address forwarding table contains following data: Destination MAC Address VLAN ID belonging to port Forwarding ingress No. of this device There are two message forwarding types according to MAC address table info: Unicast mode: the switch directly transmits the messages from the table’s egress
when MAC address forwarding table contains corresponding entries with the destination MAC address. Broadcast mode: When the switch receives the messages with the destination address full of F-bits, or there is no entry corresponding to the MAC destination address in the forwarding table, the switch will forward the messages to all ports excluding the receiving port in this way.
5.1.1 MAC Search
MAC address table needs constant updates to cater to network changes. It automatically generates entries that are limited by their lifetime (i.e. aging time). Those entries not refreshed after expiration will be deleted. The aging time of an entry will be recalculated if its record is refreshed before expiration.
Proper aging time helps to achieve the aging target of MAC address. Shortage of aging time may lead many switches broadcast to discover the packets of destination MAC addresses, thus influencing the switch performance. Aging too long can cause the switch to save outdated MAC address entries, thus exhausting the forwarding resources and failing to update the forwarding table based on network changes.
The switch may remove valid MAC address table entries due to too short aging time, thus reducing forwarding efficiency. In general, the aging time recommended is 300 seconds by default. Instructions for aging time setting: 1. Click the “Security > MAC Address > MAC Search”, in the navigation bar as follows:
27
5.1.2 Static MAC
Static table is manually configured by users and distributed to each interface board, which won’t age. Instructions: 1. Click the “Security > MAC Address > Static MAC”, in the navigation bar as follows:

5.2 Storm Control
Storms generated via broadcast, unknown multicast and unicast messages are prevented as follows. These messages will be suppressed subject to packet rates respectively. The average rate of the messages received by monitoring interfaces will be compared with the max threshold configured during an inspection interval. Configured storm policing will be performed at this interface if the average rate exceeds the max threshold.
When a L2 Ethernet interface receives the broadcast, unknown multicast or unicast messages, the device will forward them to other L2 interfaces in a same VLAN (Virtual Local Area Network) if the egress interface cannot be recognized according to destination MAC addresses. As a result, broadcast storm may occur to degrade device operation performance.
Three kinds of message flow can be controlled by storm policing characteristics to stay away from broadcast storms. Instructions: 1. Click the “Security > Storm Control”, in the navigation bar as follows:
