Jumbo Frames Support

Jumbo frames enable transporting data in fewer frames to ensure less

overhead, lower processing time, and fewer interrupts.

For information about configuring the port MTU, see "Configuring Port

Characteristics" on page 451.

Your switch supports auto-detection between crossed and straight-through

cables. Media-Dependent Interface (MDI) is the standard wiring for end

stations, and the standard wiring for hubs and switches is known as Media-

Dependent Interface with Crossover (MDIX).

Packets arriving from an unknown source address are sent to the CPU and

added to the Hardware Table. Future packets addressed to or from this

address are more efficiently forwarded.

On half-duplex links, a receiver may prevent buffer overflows by jamming the

link so that it is unavailable for additional traffic. On full-duplex links, a

receiver may send a PAUSE frame indicating that the transmitter should

cease transmission of frames for a specified period.

When flow control is enabled, the PowerConnect 8000/8100-series switches

will observe received PAUSE frames or jamming signals, but will not issue

them when congested.
