corresponding port. It can not transmit data if any port disable. The default is
“Enable”.
Flow Control
Whether selecting flow control to the port. Only can selecting flow control when
the port enable. The default is off.
The described Electric port is the common network device RJ-45 port, commonly known as "crystal
head", it's is a twisted-pair Ethernet interface type. This interface can be used in 10Base-T, 100Base-Tx
and 1000Base-Tx Ethernet, transmission media is twisted pair, but according to different bandwidth
media have different requirements, in particular, 1000Base-Tx Gigabit Ethernet connection, at least to
use cat5e.
Port Speed
Port speed shows the connecting speed of the port. It includes 3 kinds of speed: 10M, 100M and
auto-negotiation.
10M uses 10base-T standard and UTP cable for connection. When the port is in 10M speed,
Link/Act indicator will blink continuously while data transmitting and status indicator of 10M/100Mbps
will stay OFF.

User manual
Page 18
100M uses 100Base-TX standard and UTP/STP cable for connection. When the port is in 100M
speed, Link/Act indicator will blink continuously while data transmitting. 100M fiber port uses 100Base-
FX standard and single/multi-mode fiber for connection. Main fiber of 100Base-FX standard includes:
62.5nm multi-mode fiber and 50nm multi-mode fiber.Auto-negotiation includes 2 kinds of speed
according the capability of the other end: 10M and 100M.
Port Enable
This item provides a device to enable/disable the port. When choosing disable, the device would
cut off power supply of this port. Even if other device is connected to this port, all status indicators of
this port are OFF. Only enable this port, all settings about this port will be valid. This item provides a
kind of safety mechanism to protect the port from illegal use. It is not allowed to disable all the ports.
Duplx Mode
Full duplex of the switch means switch can transmit and receive data at the same time. Half duplex
of the switch means switch can transmit or receive data in a certain time. Generally the speed will
choose auto-negotiation so that the port can automatically judge the connection type of the device
connected to it and automatically adjust the connection type to ensure the maximum compatibility.
Flow Control
Flow control is used to prevent the frames from discard while port is blocked. This method is to
send back the blocking signal to its original address while sending or receiving buffer area start to
overflow. It limits the abnormal flows into a certain range. Flow control can be effective in preventing
large amounts of data in the network instant impact on the network to ensure the efficient and stable
user network running.
Two types of flow control:
1. In the half duplex mode, flow control is through back pressure. It is to send a jamming signal to
the transmission source to reduce transmission speed.
2. In the full duplex mode, flow control generally follow IEEE 802.3x standard. Switch sends
"pause" to information source to pause its sending information.
Use flow control to control the data flow between the sending and receiving nodes, can prevent
packet loss.
Polarity (MDI/MDIX auto-negotiation)
MDI-II (Medium Dependent Interface- II mode), is a kind of standard built by IEEE for RJ-45 UTP
cable of fast Ethernet 100BASE-T. II stands for parallel configuration. MDI-X(Media Dependent
Interface-x mode) and MDI- II is a kind of standard built by IEEE for RJ-45 UTP cable of fast Ethernet
100BASE-T. X stands for crossover configuration.
6.3.2 Bandwidth Management
Bandwidth management mainly refers to limit the data’s egress and ingress bandwidth to save the
network sources.
Click [port setting/bandwidth management] and enter into the following interface.
Egress Bandwidth Configuration:
“----” stands for no limitation for the speed, the others are corresponding speed.
As shown in following figure 6.3.2, the forcible egress rate of Port 4 is 8Mbps. Only need to select
8Mbps in egress rate setting of Port 4. The bandwidth of Port 4 as receiver is still 100Mbps, but the
forcible egress bandwidth of Port 4 is 8Mbps.

（Figure 6.3.2）
Ingress Bandwidth Configuration:
Ingress bandwidth limit includes 4 kinds:
1 All frames;
2 Broadcast&Multicast &unicast frames;
3 Broadcast&Multicast only;
4 Broadcast only
“----” stands for no limitation, the rate of low priority queues （L）can be setted:128k, 256k, 512k,
1M, 2M, 4M, 8M.The rate of normal priority queues（N）is 1 or 2 times as wide as that of low priority
queues. The rate of medium priority queues（M）is 1 or 2 times as wide as that of normal one. The
rate of high priority queues is 1 or 2 times as wide as that of medium one.
For example, the rate of low priority queues is 256k, then the rate of normal priority queues can be
set for 256k or 512k. Detailed operating as shown in Figure 6.3.3

configuration
For example, keep up step 1 and 2, choice “All frame” in port 4 and 5 at step 3. Set 2M in all low
priority queue
：
If priority queue bandwidth configuration is available, must mark the enter into port’s data pack as CoS.
6.4 L2 Features
6.4.1 VLAN
IES716-2GS supports based on 802.1Q VLAN. It deals with messages based on Tag of recognized
message（including 802.1p priority and VLAN ID, etc.）.
Frames with 802.1q add 4 byte Tag based on Ethernet frames, including 2 byte TPID, 3 byte
Priority, 1 byte CFI and 12 byte VLAN ID.
TPID: a 16-bit field set to a value of 0x8100 in order to identify the frame as an IEEE 802.1Q-tagged
frame.
Priority: It indicates the frame priority level. Values are from 0 (best effort) to 7 (highest); 1 represents
the lowest priority.
CFI: a 1-bit field. If the value of this field is 1, the MAC address is in non-canonical format. If the value is
0, the MAC address is in canonical format.
VLAN ID: a 12-bit field specifying the VLAN to which the frame belongs. The hexadecimal values of
0x000 and 0xFFF are reserved. All other values may be used as VLAN identifiers, allowing up to 4,094
