4.4.2 SSL Config
SSL (Secure Sockets Layer), a security protocol, is to provide a secure connection for the
application layer protocol (e.g. HTTP) communication based on TCP. SSL is widely used to
secure the data transmission between the Web browser and servers. It is mainly applied
through ecommerce and online banking.
SSL mainly provides the following services:
1. Authenticate the users and the servers based on the certificates to ensure the data are
transmitted to the correct users and servers;
2. Encrypt the data transmission to prevent the data being intercepted;
3. Maintain the integrality of the data to prevent the data being altered in the transmission.
Adopting asymmetrical encryption technology, SSL uses key pair to encrypt/decrypt
information. A key pair refers to a public key (contained in the certificate) and its corresponding
private key. By default the switch has a certificate (self-signed certificate) and a corresponding
private key. The Certificate/Key Download function enables the user to replace the default key
pair.
After SSL is effective, you can log on to the Web management page via https://192.168.0.1
. For
the first time you use HTTPS connection to log into the switch with the default certificate, you
will be prompted that “The security certificate presented by this website was not issued by a
trusted certificate authority” or “Certificate Errors”. Please add this certificate to trusted
certificates or continue to this website.
On this page you can configure the SSL function.
27
SSL:
Select Enable/Disable the SSL function on the switch.
Select the desired certificate to download to the switch. The
certificate must be BASE64 encoded.
Select the desired SSL Key to download to the switch. The key
must be BASE64 encoded.
Choose the menu System→Access Security→SSL Config to load the following page.

The following entries are displayed on this screen:

Note:
1. The SSL certificate and key downloaded must match each other; otherwise the HTTPS
connection will not work.
2. The SSL certificate and key downloaded will not take effect until the switch is rebooted.
3. To establish a secured connection using https, please enter https:// into the URL field of
the browser.
4. It may take more time for https connection than that for http connection, because https
connection involves authentication, encryption and decryption etc.
4.4.3 SSH Config
As stipulated by IFTF (Internet Engineering Task Force), SSH (Secure Shell) is a security
protocol established on application and transport layers. SSH-encrypted-connection is similar
to a telnet connection, but essentially the old telnet remote management method is not safe,
because the password and data transmitted with plain-text can be easily intercepted. SSH can
provide information security and powerful authentication when you log on to the switch
remotely through an insecure network environment. It can encrypt all the transmission data and
prevent the information in a remote management being leaked.

Chapter 5 Stack
The stack technology is to connect multiple stackable devices through their StackWise ports,
forming a stack which works as a unified system and presents as a single entity to the network
in Layer 2 and Layer 3 protocols. It enables multiple devices to collaborate and be managed as
a whole, which improves the performance and simplifies the management of the devices
efficiently.
Advantages
The stack delivers the following benefits:
1. Simplified management. After stack establishment, the user can log in the stack system
through any StackWise ports of stackable devices, and manage it as a single device. You
only need to configure the stack system once instead of operating repetitive configuration
on multiple devices. Various ways such as CONSOLE, SNMP, TELNET and WEB are
available for users to manage the stack.
2. High reliability. The stack is highly reliable in following aspects:
1） The stack system is comprised of multiple devices among which one member device
works as the stack master to take charge of the operation, management and
maintenance of the stack, while the other stack members process services and keep a
copy configuration file in accordance with the master for providing backup
simultaneously. Once the stack master becomes unavailable, the remaining stack
members elect a new master among themselves instantly and automatically, which can
ensure uninterrupted services and furthermore making 1:N backup feasible. Due to the
real-time configuration and data synchronization being strictly executed, the new
master can take over the previous master to manage and maintain the stack system
smoothly without affecting its normal operation.
2） Distributed LACP (Link Aggregation Control Protocol) supports link aggregation across
devices. Since the whole stack system presents as a single device on the network,
external devices can implement LACP with the stack system by connecting to several
stack member devices simultaneously. Among the links between the stack system and
external devices, load distribution and backup can be realized to increase the reliability
of the stack system and to simplify dramatically the network topology as Figure 5-1
shows.
35
Figure 5-1 Distributed LACP
In a ring connected stack, it can still operate normally by transforming into a daisy
chained stack when link failure occurs, which further ensures the normal operation of
load distribution and backup across devices and links as Figure 5-2 shows.
Figure 5-2 Load Distribution and Backup across Devices
3. Network scalability. Each member device in the stack system is able to process protocol
packets and forward data individually, which enables you to increase the port number and
bandwidth of the stack system by adding new member devices. The users are free to add
or remove stack members without affecting the normal running of the stack, which enables
them to protect the existed resources furthest during network upgrades.

Figure 5-3 Application Diagram
Stack Introduction
1. Stack Elements
1） Stack Role
Each device in the stack system is called stack member. Each stack member processes
services packets and plays a role which is either master or member in the stack system.
The differences between master and member are described as below:
• Master: Indicates the device is responsible for managing the entire stack system.
• Member: Indicates the device provides backup for the master. If the master fails, the
stack will elect a new master from the remaining members to succeed the previous
master.
2） Stack Event
Stack event indicates the global events which might happen during stack operation
process, with two options:
• Merge: It occurs when two independent stacks merge into one stack because of stack
link establishment, as shown in the following figure:
Figure 5-4 Stack Merge
37
When stack merge occurs, the previous masters compete to be the new master. The
stack members of the defeated stack will join the winner stack as a member to form a
new stack. Master will assign Unit Number to the newly joined members and compare
their configuration files. The members with different configurations files with the master
will download the configuration files of the master and re-configure.
• Split: It occurs when stack splits into two or more stacks because of stack link failures,
as shown in the following figure:
Figure 5-5 Stack Split
After stack partition occurs, each newly established stack elects their own new master
and use the MAC address of the master as its stack MAC address. However, stack
partition probably brings about routing and forwarding problems on the network since
the partitioned stacks keep operating with the previous IP address by default, which
results in same IP address being reused in the same LAN.
2. Operation Procedure
Stack management involves these four stages: Connecting the stack members, Topology
collection, Master election, and Stack management and maintenance.
1） Connecting the stack members
To establish a stack, please physically connect the stack ports of the member devices with
cables. The stack ports of T3700-28TQ can be used for stack connection or as normal
Ethernet Gigabit port. When you want to establish a stack, the stack mode of the related
ports should be configured as "Enable". If the stack mode of the port is "Disable", then the
port will work as a normal Ethernet port.
Stack typically adopts a daisy chain topology or ring topology as shown in Figure 5-6:
Figure 5-6 Stack Connect Topology
38
• The daisy chain topology is mainly used in a network where member devices are
distributively located.
• The ring topology is more reliable than the daisy chain topology. In a daisy chained
stack, link failure can cause stack split. While in a ring connected stack, the system is
able to operate normally with a new daisy chained topology.
Note:
Establish a stack of ring or daisy chain topology with eight T3700-28TQ switches at most.
2） Topology Collection
Each member in the stack collects the topology of the whole stack by exchanging stack
discovery packets with its neighbors. Discovery packet carries topology information
including stack port connection status, unit number, priorities, MAC addresses, etc.
Each member keeps a local record of the known topology information. When the device
initializes, it only possesses the record of its own topology information. Periodically the
stack members send out their known topology information through the stack ports to its
neighbors. When the neighbors receive the information, they will update their local
topology information. After a period of time of broadcasting and updating information, all
the stack members can collect the complete topology information (known as topology
convergence).
Then the switch enters the master election stage.
3） Master Election
After all members have obtained topology information (known as topology convergence),
the stack enters the master election stage. A stack always has one stack master, while the
other stack members are members. Master election determines the stack role of the stack
members.
Master election is held each time the topology changes, for example, when stack merge or
split occurs, or the stack or the current master is reset.
The master is elected based on the following rules and in the order listed:
1. The switch that is currently the stack master.
2. The switch with the highest stack member priority value.
3. The switch with the lowest MAC address.
After master election, the stack forms and enters into stack management and
maintenance stage.
Note:
1. The priority value ranges from 1 to 15. The higher the value is, the more likely the
member will be elected as the master. By default, the member priority of the switch is 5.
We recommend you manually assign the highest priority value to the switch that you
prefer to be the stack master before stack establishment.
2. The switch is non-preemptible when it joins the stack in cold-start mode, and the
process is illustrated as bellow: the switch has no stack role at its start, and it sends out
39
discovery messages to collect the topology of the current stack system. After the
topology collection, the switch obtains its role according to the rules above. The switch
will become stack member if there is already a master in the stack. The master will
resume its role even if the newly joined switch has a higher priority.
4） Stack Management and Maintenance
After the stack is established, all the stack members are integrated into a virtual device in
the network and managed by the master. The following section briefly introduces the
concepts and rules involved in stack management stage.
• Unit Number: When the stack is running, unit number is used to identify and manage
member devices. Unit number is unique in a stack system. The factory default unit
number of switch is 1. In order to keep its uniqueness, before establishing stack you are
kindly recommended to prepare a unit number assignment scheme and then manually
configure it on each member device.
During unit number assignment process, the master prioritizes the member devices
already carrying manually assigned unit number. If the unit number has not been used
by other stack members the member device will keep it. Otherwise, the unit number is
configured based on the following rules and in the order listed:
1. The device which was managed by the current master before the configuration will
resume its unit number.
2. The device with manually assigned unit number is prior to the device whose unit
number assignment mode is “Auto”.
3. The device with the highest stack member priority value.
4. The device with the lowest MAC address.
Note:
1. You can get the current unit number of the switch from the unit number LED on the
front panel of the switch.
2. When the stack is running, if you want to change the unit number manually, only the
unit numbers which have not been occupied by the other member devices are
available for you to choose from.
• Port Number Format:
The format of port number should be Unit Number/Slot Number/Port Number. Among
them:
(1) Unit Number: The default unit number of the switch is 1. If a device has joined
stack system, the unit number which the device possesses in the stack system
will be kept using as its unit number after the device leaves the stack system.
(2) Slot Number: Indicates the number of the slot the interface card is in. For
T3700G-28TQ, the front panel ports belong to slot 0. Slot number starting from 1
each represents an interface card slot.
(3) Physical Port Number: The physical port number on the switch which can be
obtained through the front panel of the switch.
40
For instance: Port number 2/0/3 indicates the physical port3 on the switch whose unit
number is 2.
• Configuration Files Application Rules: It includes global configuration and interface
configuration two parts.
(1) The global configurations of all stack members are the same. Besides, each
member device keeps pace with the global configuration of the master device
which enables the stack system to work just like a single entity in the network. The
stack system adopts the following methods to ensure the synchronization of
global configuration files:
When the stack initializes, the master device will compare the configuration files
of each stack member and reconfigure the device whose global configuration is
different from its own, so as to ensure the global configuration of the stack
members are exactly the same.
When the stack is work normally, any global configuration of users will be
recorded to the current configuration files of master and then be synchronized to
the other members in the stack.
(2) Each stack member only saves the configuration of its own ports. Even when user
sets the configuration for all ports, the configuration will also be saved and
implemented only on the related stack member which the ports belong to.
• Stack Maintenance
Stack maintenance mainly functions to monitor the join and leave of member devices,
collect the new topology at any times and maintain the current topology.
When the stack is operating normally, packets are transmitted constantly between
stack members. The switch can quickly judge the link status of the stack port via
monitoring the response of the packets. When the switch detects the link status
changes, it will recollect system topology and update topology database to ensure the
normal operation of the stack.
The events that will change the link status of the stack port which thus affecting the
system topology include: stack member failure or leave, new member's coming, link
failure or failure recovery, etc.
When the master switch fails, the stack system elects a new master from the remaining
members to succeed the previous master.
5.1 Stack Management
Before configuring the stack, we highly recommend you to prepare the configuration planning
with a clear set of the role and function of each member device. Some configuration needs
device reboot to take effect, so you are kindly recommended to configure the stack at first,
next connect the devices physically after powering off them, then you can power them on and
the devices will join the stack automatically. After stack is established, users can log in the
stack system through any member devices to configure and manage it.
The stack management can be implemented on Stack Info, Stack Config and Switch
Renumber pages.

6.1 Port
The Port function, allowing you to configure the basic features for the port, is implemented on
the Port Config, Port Mirror, Port Security, Port Isolation and Loopback Detection pages.
6.1.1 Port Config
On this page, you can configure the basic parameters for the ports. When the port is disabled, the
packets on the port will be discarded. Disabling the port which is vacant for a long time can
reduce the power consumption effectively. And you can enable the port when it is in need.
The parameters will affect the working mode of the port, please set the parameters appropriate
to your needs.

3. The Port Mirror function can span the multiple VLANs.
6.1.3 Port Security
MAC Address Table maintains the mapping relationship between the port and the MAC
address of the connected device, which is the base of the packet forwarding. The capacity of
MAC Address Table is fixed. MAC Address Attack is the attack method that the attacker takes
to obtain the network information illegally. The attacker uses tools to generate the cheating
MAC address and quickly occupy the MAC Address Table. When the MAC Address Table is full,
the switch will broadcast the packets to all the ports. At this moment, the attacker can obtain
the network information via various sniffers and attacks. When the MAC Address Table is full,
the packets traffic will flood to all the ports, which results in overload, lower speed, packets
drop and even breakdown of the system.
Port Security is to protect the switch from the malicious MAC Address Attack by limiting the
maximum number of MAC addresses that can be learned on the port. The port with Port
Security feature enabled will learn the MAC address dynamically. When the learned MAC
address number reaches the maximum, the port will stop learning. Thereafter, the other
devices with the MAC address unlearned cannot access to the network via this port.

6.2 LAG
LAG (Link Aggregation Group) is to combine a number of ports together to make a single
high-bandwidth data path, so as to implement the traffic load sharing among the member ports
in the group and to enhance the connection reliability.
For the member ports in an aggregation group, their basic configuration must be the same. The
basic configuration includes STP, QoS, GVRP, VLAN, port attributes, MAC Address Learning
mode and other associated settings. More details are explained below:
If the ports, which are enabled for the IGMP, IGMP Snooping, GVRP, 802.1Q VLAN, Voice
VLAN, STP, QoS, Port Isolation, DHCP Snooping and Port Configuration (Speed, Flow
Control), are in a LAG, their configurations should be the same.
The ports, which are enabled for the Port Security, Port Mirror, MAC Address Filtering,
Static MAC Address Binding, 802.1X Authentication, IP Source Guard, half-duplex and
Routed Port cannot be added to the LAG.
It’s not suggested to add the ports with ARP Inspection and DoS Defend enabled to the
LAG.

If the LAG is needed, you are suggested to configure the LAG function here before configuring
the other functions for the member ports.
Tips:
1. Calculate the bandwidth for a LAG: If a LAG consists of the four ports in the speed of
1000Mbps Full Duplex, the whole bandwidth of the LAG is up to 8000Mbps (2000Mbps * 4)
because the bandwidth of each member port is 2000Mbps counting the up-linked speed
of 1000Mbps and the down-linked speed of 1000Mbps.
2. The traffic load of the LAG will be balanced among the ports according to the Aggregate
Arithmetic. If the connections of one or several ports are broken, the traffic of these ports
will be transmitted on the normal ports, so as to guarantee the connection reliability.
Depending on different aggregation modes, aggregation groups fall into two types: Static LAG
and LACP Config. The LAG function is implemented on the LAG Table, Static LAG and LACP
Config configuration pages.

6.2.3 LACP Config
LACP (Link Aggregation Control Protocol) is defined in IEEE802.3ad/802.1ax and enables the
dynamic link aggregation and disaggregation by exchanging LACP packets with its partner. The
switch can dynamically group similarly configured ports into a single logical link, which will
highly extend the bandwidth and flexibly balance the load.
With the LACP feature enabled, the port will notify its partner of the system priority, system
MAC, port priority, port number and operation key (operation key is determined by the physical
properties of the port, upper layer protocol and admin key). The device with higher priority will
lead the aggregation and disaggregation. System priority and system MAC decide the priority
of the device. The smaller the system priority, the higher the priority of the device is. With the
same system priority, the device owning the smaller system MAC has the higher priority. The
device with the higher priority will choose the ports to be aggregated based on the port priority,
port number and operation key. Only the ports with the same operation key can be selected
into the same aggregation group. In an aggregation group, the port with smaller port priority will
be considered as the preferred one. If the two port priorities are equal, the port with smaller
port number is preferred. After an aggregation group is established, the selected ports can be
aggregated together as one port to transmit packets.
On this page, you can configure the LACP feature of the switch.

To fully utilize the MAC address table, which has a limited capacity, the switch adopts an aging
mechanism for updating the table. That is, the switch removes the MAC address entries related
to a network device if no packet is received from the device within the aging time.

Tips:
Setting aging time properly helps implement effective MAC address aging. The aging time that
is too long or too short results in a decrease of the switch performance. If the aging time is too
long, excessive invalid MAC address entries maintained by the switch may fill up the MAC
address table. This prevents the MAC address table from updating with network changes in
time. If the aging time is too short, the switch may remove valid MAC address entries. This
decreases the forwarding performance of the switch. It is recommended to keep the default
value.
6.4.4 Filtering Address
The filtering address is to forbid the undesired packets to be forwarded. The filtering address
can be added or removed manually, independent of the aging time. The filtering MAC address
allows the switch to filter the packets which includes this MAC address as the source address
or destination address, so as to guarantee the network security. The filtering MAC address
entries act on all the ports in the corresponding VLAN.

Chapter 7 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. Though connecting the
LANs through switches can avoid the serious collision, the flooding broadcasts cannot be
prevented, which will occupy plenty of bandwidth resources, causing potential serious security
problems.
A Virtual Local Area Network (VLAN) is a network topology configured according to a logical
scheme rather than the physical layout. The VLAN technology is developed for switches to
control broadcast in LANs. By creating VLANs in a physical LAN, you can divide the LAN into
multiple logical LANs, each of which has a broadcast domain of its own. Hosts in the same
VLAN communicate with one another as if they are in a LAN. However, hosts in different VLANs
cannot communicate with one another directly. Therefore, broadcast packets are limited in a
VLAN. Hosts in the same VLAN communicate with one another via Ethernet whereas hosts in
different VLANs communicate with one another through the Internet devices such as Router,
the Layer3 switch, etc. The following figure illustrates a VLAN implementation.
Figure 7-1 VLAN implementation
Compared with the traditional Ethernet, VLAN enjoys the following advantages.
(1) Broadcasts are confined to VLANs. This decreases bandwidth utilization and improves
network performance.
(2) Network security is improved. VLANs cannot communicate with one another directly.
That is, a host in a VLAN cannot access resources in another VLAN directly, unless
routers or Layer 3 switches are used.
(3) Network configuration workload for the host is reduced. VLAN can be used to group
specific hosts. When the physical position of a host changes within the range of the
VLAN, you need not to change its network configuration.
72
A VLAN can span across multiple switches, or even routers. This enables hosts in a VLAN to be
dispersed in a looser way. That is, hosts in a VLAN can belong to different physical network
segment. This switch supports three ways, namely, 802.1Q VLAN, MAC VLAN and Protocol
VLAN, to classify VLANs. VLAN tags in the packets are necessary for the switch to identify
packets of different VLANs. The switch can analyze the received untagged packets on the port
and match the packets with the MAC VLAN, Protocol VLAN and 802.1Q VLAN in turn. If a
packet is matched, the switch will add a corresponding VLAN tag to it and forward it in the
corresponding VLAN.
7.1 802.1Q 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.
In 1999, IEEE issues the IEEE 802.1Q protocol to standardize VLAN implementation, defining
the structure of VLAN-tagged packets. IEEE 802.1Q protocol defines that a 4-byte VLAN tag is
encapsulated after the destination MAC address and source MAC address to show the
information about VLAN.
As shown in the following figure, a VLAN tag contains four fields, including TPID (Tag Protocol
Identifier), Priority, CFI (Canonical Format Indicator), and VLAN ID.
Figure 7-2 Format of VLAN Tag
(1) TPID: TPID is a 16-bit field, indicating that this data frame is VLAN-tagged. By default, it
is 0x8100.
(2) Priority: Priority is a 3-bit field, referring to 802.1p priority. Refer to section “QoS & QoS
profile” for details.
(3) CFI: CFI is a 1-bit field, indicating whether the MAC address is encapsulated in the
standard format in different transmission media. This field is not described in detail in
this chapter.
(4) VLAN ID: VLAN ID is a 12-bit field, indicating the ID of the VLAN to which this packet
belongs. It is in the range of 0 to 4,095. Generally, 0 and 4,095 is not used, so the field is
in the range of 1 to 4,094.
VLAN ID identifies the VLAN to which a packet belongs. When the switch receives an
un-VLAN-tagged packet, it will encapsulate a VLAN tag with the default VLAN ID of the inbound
port for the packet, and the packet will be assigned to the default VLAN of the inbound port for
transmission.
In this User Guide, the tagged packet refers to the packet with VLAN tag whereas the untagged
packet refers to the packet without VLAN tag, and the priority-tagged packet refers to the
packet with VLAN tag whose VLAN ID is 0.

When creating the 802.1Q VLAN, you should set the link type for the port according to its
connected device. The link types of port including the following three types:
(1) ACCESS: The ACCESS port can be added in a single VLAN, and the egress rule of the
port is UNTAG. The PVID is same as the current VLAN ID. If the ACCESS port is added to
another VLAN, it will be removed from the current VLAN automatically.
(2) TRUNK: The TRUNK port can be added in multiple VLANs. The egress rule of the port is
UNTAG if the arriving packet’s VLAN tag is the same as the port’s PVID, otherwise the
egress rule is TAG. The TRUNK port is generally used to connect the cascaded network
devices for it can receive and forward the packets of multiple VLANs.
(3) GENERAL: The GENERAL port can be added in multiple VLANs and set various egress
rules according to the different VLANs. The default egress rule is UNTAG. The PVID can
be set as the VID number of any valid VLAN.
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) 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
(2) PVID determines the default broadcast domain of the port, i.e. when the port receives
UL packets or broadcast packets, the port will broadcast the packets in its default
VLAN.
Different packets, tagged or untagged, will be processed in different ways, after being received
by ports of different link types, which is illustrated in the following table.

the 802.1Q VLANs the ingress port belongs to.
7.3 MAC VLAN
MAC VLAN technology is the way to classify VLANs according to the MAC addresses of Hosts.
A MAC address corresponds to a single VLAN ID. For the device in a MAC VLAN, if its MAC
address is bound to VLAN, the device can be connected to another member port in this VLAN
and still takes its member role effect without changing the configuration of VLAN members.
The packet in MAC VLAN is processed in the following way:
1. When receiving an untagged packet, the switch matches the packet with the current MAC
VLAN. If the packet is matched, the switch will add a corresponding MAC VLAN tag to it. If
no MAC 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. When receiving tagged packet, the switch will process it basing on the 802.1Q VLAN. If the
received port is the member of the VLAN to which the tagged packet belongs, the packet
will be forwarded normally. Otherwise, the packet will be discarded.
3. If the MAC address of a Host is classified into 802.1Q VLAN, please set its connected port
of switch to be a member of this 802.1Q VLAN so as to ensure the packets forwarded
normally.

7.5 Protocol VLAN
Protocol VLAN is another way to classify VLANs basing on network protocol. Protocol VLANs
can be sorted by IP, IPX, DECnet, AppleTalk, Banyan and so on. Through the Protocol VLANs,
the broadcast domain can span over multiple switches and the Host can change its physical
position in the network with its VLAN member role always effective. By creating Protocol
VLANs, the network administrator can manage the network clients basing on their actual
applications and services effectively.
This switch can classify VLANs basing on the common protocol types listed in the following
table. Please create the Protocol VLAN to your actual need.
Table 7-2 Protocol types in common use
The packet in Protocol VLAN is 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. When receiving tagged packet, the switch will process it basing on the 802.1Q VLAN. If the
received port is the member of the VLAN to which the tagged packet belongs, the packet
will be forwarded normally. Otherwise, the packet will be discarded.
3. If the Protocol VLAN is created, please set its enabled port to be the member of
corresponding 802.1Q VLAN so as to ensure the packets forwarded normally.
