Configuring Jumbo Frames Using CLI Commands
The following table summarizes the CLI commands for configuring Jumbo
frames.
The following is an example of the CLI commands:
Green Ethernet Configuration
Green Ethernet is a name of a set of features that are designed to reduce the
power consumption of a device, and so make it environmentally friendly.
The Green Ethernet feature reduces overall power usage in the following
ways:
• Energy Efficient Ethernet — When using EEE, systems on both sides of
the link can disable portions of their functionality and save power during
periods of low link utilization. EEE is a hardware feature that is enabled by
default, and is transparent to users. This feature is defined per port,
regardless of their LAG membership.
• Link Short-Reach Energy Saving Mode — Power usage is adjusted to the
actual cable length. In this mode, the VCT (Virtual Cable Tester) length
test is performed to measure cable length. If the cable is shorter than a
predetermined length, the switch reduces the power used to send frames
over the cable, thus saving energy. This mode is only supported on RJ45
ports.
