Port Configuration
Ports Settings
You can use the Port Configuration page to manually set the speed, duplex
mode, and flow control.
Field Attributes
• Enable Jumbo Frames – This switch provides more efficient
throughput for large sequential data transfers by supporting jumbo
frames on Gigabit Ethernet ports up to 9216 bytes. 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.
IEEE 802.3 defines the Ethernet standard and subsequent power
requirements based on cable connections operating at 100 meters.
Enabling power saving mode can significantly reduce power used for
cable lengths of 20 meters or less, and continue to ensure signal integrity.
• Speed/Duplex – Allows you to manually set the port speed and duplex
mode.
• Flow Control – Allows flow control to be enabled or disabled. When the
box is checked, flow control is enabled.
• Trunk – Indicates if a port is a member of a trunk.
Note: Ports within a trunk cannot be configured individually. However,
you can use the “Trunk Configuration” page to manually set the
same speed, duplex mode, and flow control for every port in a
trunk.
Web – Click PORTS, Settings. Enable or disable jumbo frames, select the
required settings for any port, and then click APPLY.
