4.2.1 Port Parameter

4.2.1.1 Duplex Mode
Ports have the duplex modes: 10M HD, 10M FD, 100M HD, 100M FD and
1000M FD (Giga port support).
The First part indicates the transmission rate and the second part indicates the
duplex mode.
HD: half-duplex, the port supports transmission between the device and
the client in only one direction at a time.
FD: full-duplex, the port supports transmission between the device and its
link partner in both directions simultaneously.
Switch support auto negotiation is a protocol between two link partners that
enables a port to advertise its transmission rate and duplex mode to its
partner.
4.2.1.2 Flow Control
Flow control enables lower speed devices to communicate with higher speed
devices. This is implemented by the higher speed device refraining from
sending packets.
4.2.1.3 Port Security

TL-SG2109WEB/TL-SL2210WEB/TL-SL2218WEB/TL-SL2428WEB/TL-SL2452WEB
If the port security is enabled, it will not learn new MAC address and only
transmit the frames from the MAC address list in the port’s static MAC address
table.

4.2.2 Port Statistic and Port Status

Port Statistic calculates the statistics of each port, such as how many frames,
error frames, broadcast frames it has received, and so on.
Port Status indicates whether the port is linked, not linked or disabled, what
speed and duplex mode it is working on, and whether ow control is enabled
or disabled.

4.2.3 Storm Control

Storm control limits the amount of multicast, broadcast and UL (the address
hasn't been learned) frames accepted and forwarded by the device. When
Layer 2 frames are forwarded, broadcast, multicast and UL frames are ooded
to all ports on the relevant VLAN. This occupies bandwidth, and loads all
nodes on all ports.
A Storm is a result of an excessive amount of these frames simultaneously
transmitted across a network by a single port. Forwarded message responses
are heaped onto the network, straining network resources or causing the
network to time out. Storm control is enabled for all ports by defining the
packet type and the rate at which the packets are transmitted. The system
measures the incoming dened frame rates on each port, and discards the
frames when the rate exceeds a user-dened rate.

4.2.4 Port Description

Use a description word to indicate the port.

4.3 Network Setting

The network module provides the function of setting switch IP address,
dynamic binding and aging time, conguring static MAC address and ltering
MAC address, displaying dynamic bound address and ping.

4.3.1 Switch IP Address

An IP address is indispensable for a switch to be accessed. TheTL-
SG2109WEB/TL-SL2210WEB/TL-SL2 218 WEB /TL -SL2428WEB/TL-
SL2452WEB Web-Smart Switch Family provides the conguration interface of
IP address, netmask and default gateway.
DHCP (Dynamic Host Conguration Protocol) is dedicated for the DHCP client
to obtain IP configuration information from the DHCP server. Two types of
information are included in IP conguration information. One type is specic
conguration information; another is IP address parameter. DHCP is based
on client-server mode. The network station that offers the IP configuration
information is called DHCP server.
Make sure that a DHCP server is correctly connected to the network, enable
the DHCP client function of the switch, then the switch will automatically obtain
IP address, netmask and default gateway from the DHCP server.
If more than one DHCP servers are available in the network, the switch will
choose one according to a specic algorithm.

Notice:
If no DHCP server is present in the network, the DHCP client fails to get IP
conguration information, the switch then restores the IP parameters to default
in several minutes to ensure a valid IP address being equipped.

4.3.2 Aging Time and Dynamic Address Table

A dynamic MAC address table is maintained inside the switch. A MAC address
is the physical address of a network device; it is six-bytes long and should be
hole in a subnet. A network device can be identied by its MAC address.
A dynamic address table entry contains two items: MAC address and its
corresponding switch port. The dynamic address table is volatile. The dynamic
address entry begins to age once it has been added; it will be purged if it isn’t
renewed in a specied length of time, which is dened as aging time.
The aging time ranges from 0 to 3825 seconds for this switch family.
The default value is 300 seconds. Dynamic address table entry won’t age if 0
is set. The aging time precision is 15 seconds.

4.3.3 Static MAC Address Table

A sta tic MAC address table entry contains a MAC address a nd its
corresponding switch port. All the packets taking that MAC address as their
destination will be forwarded to the corresponding switch port.
The static MAC address won’t age, which differs from the dynamic MAC
address. The static MAC address table entry is always valid before it is
deleted.
