Switching Switching
User Guide 31
1 Switching
1.1 Overview
With the Switching function, you can configure port setting, IGMP Snooping and LAG.
1.2 Supported Features
The switch supports the following features about switching:
Port Setting
You can configure port status, speed, duplex mode, and flow control for ports.
IGMP Snooping
In a point-to-multipoint network, packets can be sent in three ways: unicast, broadcast
and multicast. With unicast, many copies of the same information will be sent to all the
receivers, occupying a large bandwidth.
With broadcast, information will be sent to all users in the network no matter they need it or
not, wasting network resources and impacting information security.
Multicast, however, solves all the problems caused by unicast and broadcast. With
multicast, the source only needs to send one piece of information, and all and only the users
who need the information will receive copies of the information. In a point-to-multipoint
network, multicast technology not only transmits data with high efficiency, but also saves a
large bandwidth and reduces network load.
When IGMP Snooping is disabled on the switch, multicast packets will be broadcast in
the Layer 2 network; when IGMP Snooping is enabled on the switch, multicast data from
User Guide 32
Switching Switching
a known multicast group will be transmitted to the designated receivers instead of being
broadcast in the Layer2 network. The following figure shows how IGMP snooping works.

LAG
With LAG (Link Aggregation Group) function, you can aggregate multiple physical ports into
a logical interface to increase link bandwidth and enhance the connection reliability.
Switching Configuring Ports
User Guide 33
2 Configuring Ports
Choose the menu Switching > Port Setting to load the following page.
Figure 2-1 Configuring Ports
Follow these steps to configure the port parameters.
1) Select the desired ports and set basic parameters for the ports.
Status Enable or disable the port. With this option enabled, the port forwards packets
normally. Otherwise, the port does not forward packets. By default, it is enabled.
Speed/Duplex Config: Select the appropriate speed and duplex mode for the port. When Auto
is selected, the port automatically negotiates speed mode with the connected
device. The default setting is Auto. It is recommended to select Auto if both ends
of the link support auto-negotiation.
Actual: Displays the actual working state of the port.
Flow Control Config: Select On or Off to enable or disable the Flow Control feature. When Flow
Control is enabled, when the switch get overloaded, it will send a PAUSE frame
to notify the peer device to stop sending data for a specific period of time, thus
avoiding the packet loss caused by congestion. By default, it is Off.
Actual: Displays the current state of the Flow Control function of the port.
User Guide 34
Switching Configuring Ports
LAG Displays the LAG which the port belongs to.
2) Click Apply.
Note:
●It is recommended to set the ports on both ends of a link with the same speed and duplex
mode.
●Keep the port that is connected to the management device enabled, or you cannot access the
switch.
●The parameters of the port members in a LAG should be set as the same.

IGMP Snooping Enable or disable IGMP Snooping globally.
Report Message
Suppression
Enable or disable Report Message Suppression globally. When enabled, the
switch will only forward the first IGMP report message for each multicast group to
the IGMP querier and suppress subsequent IGMP report messages for the same
multicast group during one query interval. This feature prevents duplicate report
messages from being sent to the IGMP querier.
2) In the Multicast IP Table section, you can view the current IGMP group information.
IP Address Displays the IP address of the multicast group.
VLAN ID Displays the VLAN ID of the multicast group. All port members of a multicast
group should be included in the same VLAN.

Port Statistics is used to display the information of each port, which facilitates you to
monitor the traffic and locate faults promptly.
Port Mirror
Port Mirror is used to monitor network traffic by forwarding copies of incoming and
outgoing packets from one or multiple ports (mirrored ports) to a specified port (mirroring
port). Generally, the mirroring port is connected to a data diagnosis device, which is used
to analyze the mirrored packets for monitoring and troubleshooting the network.
Cable Test
The switch provides cable test to diagnose the connection status of the cable connected
to the switch and the distance to the problem location, which facilitates you to locate and
diagnose the trouble spot of the network.

Configuring VLAN Overview
User Guide 51
1 Overview
VLAN (Virtual Local Area Network) is a network technique that solves broadcasting issues
in local area networks. It is usually applied in the following occasions:
■To restrict broadcast domain: VLAN technique divides a big local area network into
several VLANs, and all VLAN traffic remains within its VLAN. It reduces the influence of
broadcast traffic in Layer 2 network to the whole network.
■To enhance network security: Devices from different VLANs cannot achieve Layer 2
communication, and thus users can group and isolate devices to enhance network
security.
■For easier management: VLANs group devices logically instead of physically, so devices
in the same VLAN need not be located in the same place. It eases the management of
devices in the same work group but located in different places.
There are 3 types of VLAN modes supported on the switch:
■MTU VLAN
MTU VLAN (Multi-Tenant Unit VLAN) defines an uplink port which will build up several
VLANs with each of the other ports. Each VLAN contains two ports, the uplink port and
one of the other ports in the switch, so the device connected to the uplink port can
communicate with the device connected to any other port, but devices connected to other
ports cannot communicate with each other.
■Port Based VLAN
VLANs are divided based on ports. In port based VLAN mode, each port can only be added
to one VLAN.
■802.1Q VLAN
The IEEE 802.1Q protocol defines a new format of VLAN data frame (Tagged Frame). As the
following figure shows, compared to the traditional Ethernet data frame (Untagged Frame),
the VLAN data frame (Tagged Frame) adds a VLAN tag.

switch will first insert a VLAN tag to the frame, using the PVID (Port VLAN ID) of the port as
its VID, and then forward it as a tagged frame.
Note:
●The switch works in one and only one VLAN mode at any time. When a specific VLAN mode
is enabled, the other two VLAN modes will be disabled automatically and the corresponding

User Guide 65
1 QoS
1.1 Overview
With network scale expanding and applications developing, internet traffic is dramatically
increased, thus resulting in network congestion, packet drops and long transmission delay.
Typically, networks treat all traffic equally on FIFO (First In First Out) delivery basis, but
nowadays many special applications like VoD, video conferences, VoIP, etc. require more
bandwidth or shorter transmission delay to guarantee the performance.
With QoS (Quality of Service) technology, you can classify and prioritize network traffic to
provide differentiated services to certain types of traffic.
1.2 Supported Features
With the QoS feature, You can configure QoS Basic, Bandwidth Control and Storm Control
on the switch to maximize the network performance and bandwidth utilization.
QoS Basic
The switch classifies the ingress packets, maps the packets to different priority queues
and then forwards the packets to implement QoS function.
Bandwidth Control
Bandwidth Control functions to control the ingress traffic rate and egress traffic rate on
each port via configuring the available bandwidth of each port. In this way, the network
bandwidth can be reasonably distributed and utilized.
Storm Control
Storm Control function allows the switch to monitor broadcast packets, multicast packets
and UL-frames (Unknown unicast frames) in the network. If the transmission rate of the
packets exceeds the limit, the packets will be automatically discarded to avoid network
broadcast storm.
User Guide 66
Configuring QoS Configuring Basic QoS
2 Configuring Basic QoS
Configuration Guidelines
Select the QoS mode according to your network requirements. Three QoS modes are
supported on the switch: Port Based, 802.1P Based and DSCP Based (DSCP/802.1P
Based).
■Port Based
The port based QoS mode supports four priority queues, which are labeled as 1 (Lowest),
2(Normal), 3 (Medium) and 4 (Highest).
In this mode, the switch prioritizes packets according to their ingress ports, regardless of
the packet field or type.
■802.1P Based
802.1P defines the first three bits in 802.1Q Tag as PRI field. The PRI values are from 0 to7.
The tagged packets are mapped to 4 priority levels based on the PRI value (Lowest=0, 1;
Normal=2, 3; Medium=4, 5; Highest=6, 7).
In this mode, the switch only prioritizes packets with VLAN tag, regardless of the IP header
of the packets.
■DSCP/802.1P Based
DSCP priority determines the priority of packets based on the ToS (Type of Service) field
in their IP header. RFC 2474 re-defines the ToS field in the IP packet header as DS field.
The first six bits of the DS field is used to represent DSCP priority. The DSCP values are
from 0 to 63. The IP packets are mapped to 4 priority levels based on the DSCP value
(Lowest=0-15; Normal=16-31; Medium=32-47; Highest=48-63).
In this mode, the switch prioritizes packets with IP header based on DSCP priority first.
Then, the switch prioritizes packets with VLAN tag but without IP header based on the PRI
field. Finally, the switch prioritizes packets without VLAN tag or IP header based on port
priority.

PoE (Power over Ethernet) is a remote power supply function. With this function, the switch
can supply power to the connected devices over twisted-pair cables.
Some devices such as IP phones, access points (APs) and cameras may be located far
away from the AC power source in actual use. PoE can provide power for these devices
without requiring to deploy power cables. This allows a single cable to provide both data
connection and electric power for the device.
■PSE
Power sourcing equipment (PSE) is a device that provides power for PDs on the Ethernet,
for example, the PoE switch. PSE can detect the PDs and determine the device power
requirements.
■PD
Powered device (PD) is a device receiving power from the PSE, for example, IP phones and
access points. According to whether PDs comply with IEEE standard, they can be classified
into standard PDs and non-standard PDs. Only standard PDs can be powered via TP-Link

corresponding port to avoid PD’s damage.
●It is recommended to configure the switch and its connected PDs to the same subnet, and
when 802.1Q VLAN enabled, the connected PD should be in the port’s default VLAN (whose ID
is the PVID). For detailed configurations, refer to
Configuring 802.1Q VLAN
.
2) In the Port Config section, select the desired ports and specify the parameters . Click
Apply.
Ping IP Address Enter the IP address of the PD connected to the port.
Ping IP Address should be the same as the connected PD’s IP address.
Otherwise, the switch will continually reboot the PD.

Startup Delay Specify how long the switch waits for the connected PD’s rebooting before the
switch starts to ping the PD’s IP address.
Interval Specify the interval between two consecutive ping packets.
Failure Threshold Specify the threshold for ping failures.
If the switch fails to get the ping response from the PD on the port, the switch
will retry until the number of ping failures reaches the threshold, then the switch
reboots the PD.
Break Time Specify how soon the switch reboots the PD after the number of ping failures
reaches the threshold.
Failures Display the number of ping failures since the latest reboot of the PD. It will be
reset when the PD responds to the ping packet or is rebooted.
Reboots Display the number of PD’s reboots. It will be reset after reaching 9,999 or
when the switch is rebooted.
Total Pings Display the total number of ping packets that the switch sends to the
connected PD. It will be reset after reaching 9,999 or when the switch is
rebooted.
