4 Port Management
4.1 Configuring Port
Port configuration can be used to configure basic parameters which are related to switch port. The
port parameters will directly affect the working mode of the port. Make configurations according to
the practical requirements.
Step 1 Select Port Management > Port Configuration on the System Info page.
Figure 3-1 Configure port
Step 2 Configure port parameters.
Table 3-1 Description of parameters
Parameter Description
Port Displays the Switch port number.
Description Add description information for port.
Link Displays the port link status.
Enable
Configure port on and off.
●On: Enable the link.
●Off: Disable the link.
Speed Duplex Status Displays the status of the port speed.

10
Parameter Description
Speed Duplex Setting
Configure the modes of the port speed duplex.
●Ethernet port.
◇Auto (default): Auto negotiation mode.
◇10 M FULL: 10 M full duplex.
◇10 M HALF: 10 M half duplex.
◇100 M FULL: 100 M full duplex.
◇100 M HALF: 100 M half duplex.
◇1000 M FULL: 1000 M full duplex.
●Fiber port.
◇1000 M FULL: 1000 M full duplex.
The port communication can be directly affected if you change the
port speed duplex mode. Please be advised.
Flow Control
Configure the Switch flow control.
●On: Enable port flow control function.
●Off: Disable port flow control function.
For Ethernet port, you need to enable port flow control function to
synchronize the inbound speed and the outbound speed to avoid
packet losses.
Step 3 Click Save.
4.2 Configuring Port Mirroring
Port mirroring (also called port monitor) is the process of copying the packet of a port or several
ports (called the source port) to another port (called the destination port), which is connected with a
monitoring device for packet analysis. This enables monitoring the network and resolving the
network malfunction.
Step 1 Select Port Management > Port Mirroring on the System Info page.
Step 2 Configure parameters.

11
Figure 3-2 Configure port mirroring
Table 3-2 Description of parameters
Parameter Description
Monitored Packets
Select mirrored packets.
●Disable (default): Disable the monitor function.
●Egress: Monitor output packets.
●Ingress: Monitor input packets.
●Ingress & Egress: Monitor input/output packets.
Dest Port The Port that is used to monitor. You can select only one port. The
default setup is disabled.
Src port The port that is being monitored. Select one or more port(s).
Enable Enable the function on the selected ports.
Step 3 Click Save.
4.3 Configuring Port Statistics
You can view port statistics including the transmit/receive packet amount of each port, collision
statistics, drop packet and CRC error packet. The port working performance is low if the error packet
amount is too huge. Check the port cable connection or confirm corresponding opposite port has
problem or not.
Procedure
Step 1 Select Port Management > Port Statistics on the System Info page.

12
Figure 3-3 Configure port statistics
Step 2 Select Counter Mode Selection, including Transmit Packet & Receive Packet, Collision
Packet & Transmit Packet, Drop Packet & Receive Packet and CRC (Cyclic Redundancy
Check)Error Packet & Receive Packet, and then view the results.
If there are too many error packets from the port, the working status of the port is very
poor. Make sure to check if there is a problem with the cable connected to the port or the
Switch.
Related Operations
●Clear statistic results: Click Clear.
●Refresh statistic results: Click Refresh.
4.4 Configuring Port Speed Limit
You can set port speed limit parameters, and restrict exchanging rate of inbound/outbound data
packets.
Step 1 Select Port Management > Port Speed Limit on the System Info page.
Step 2 Configure parameters.

13
Figure 3-4 Port speed limit
Table 3-3 Description of the port speed limit parameter
Name Note
Port Displays port list.
Tx Rate Set port outbound rate. The value ranges from 0 through 63 Mbps. The
default setup is 0, which means there is no speed limit.
Rx Rate Set port inbound rate. The value ranges from 0 through 63 Mbps. The default
setup is 0, which means there is no speed limit.
Step 3 Click Save.
4.5 Configuring Broadcast Storm Control
Background Information
The broadcast frames on the network are forwarded continuously, which affects the proper
communications, and greatly reduces the network performance. The storm control can limit the
broadcast flows of the port and discard the broadcast frames once the flow exceeds the specified
threshold, which can reduce the risk of the broadcast storm and ensure the network proper
operation.
Procedure
Step 1 Select Port Management > Broadcast Storm Control on the System Info page.
Step 2 Configure Threshold.
