Chapter 3: Software Description
3.2.2 Ports
Port Security ensures access to a switch port based on MAC address, limits the
total number of devices from using a switch port, and protects against MAC
flooding attacks.
3.2.2.1 Port Configuration
In Port Configuration, you can set and view the operation mode for each port.
• Enable Jumbo Frames: This switch provides more efficient throughput for large
sequential data transfers by supporting jumbo frames on Gigabit Ethernet ports
up to 9.6 KB. Compared to standard Ethernet frames that run only up to 1.5 KB,
using jumbo frames significantly reduces the per-packet overhead required to
process protocol encapsulation fields.
• Power Saving Mode: Adjusts the power provided to ports based on the length
of the cable used to connect to other devices. Only sufficient power is used to
maintain connection requirements.
• Mode: Manually set the port speed such as auto, 10 half, 10 full, 100 half,
100 full, 1000 full. or disabled. Click on the “Apply” button to complete the
configuration.
Flow Control
Click the check box (x) to enable flow control. If flow control is set to enable, both
parties can send PAUSE frames to the transmitting device(s) if the receiving port is
too busy to handle the amount of data being sent. When it is set to disable, there
will be no flow control on that port. The port will drop packets if the amount of
data becomes too much for the port to handle.
