Transmissions are temporarily halted to prevent buffer overflows. For information on configuring Flow Control for ports or LAGs, see "Defining Port Parameters" or "Defining LAG Parameters." Back Pressure Support On half-duplex links, the receiving port prevents buffer overflows by occupying the link so that it is unavailable for additional traffic. For information on configuring Back Pressure for ports or LAGs, see "Defining Port Parameters" or "Defining LAG Parameters." Jumbo Frames Support Jumbo frames are frames with an MTU size of up to 10K bytes, and better utilize the network by transporting the same data using less frames. The main benefits of this facility are reduced transmission overhead, and reduced host processing overhead. Jumbo are used for server-to-server transfers. For information on enabling Jumbo Frames, see "Configuring System Information." 10 Introduction

Features

This section describes the Ethernet Switch Module user-configured features. For a complete list of

all updated Ethernet Switch Module features, see the latest software version

Release Notes

General Features

Head of Line Blocking

Head of Line (HOL) blocking results in traffic delays and frame loss caused by traffic competing

for the same egress port resources. HOL blocking queues packets, and the packets at the head of

the queue are forwarded before packets at the end of the queue. By default HOL blocking is active

at all times except when QoS, Flow Control, or Back Pressure is active on a port, the HOL blocking

prevention mechanism is disabled on the whole system.

Flow Control Support (IEEE 802.3X)

Flow control enables lower speed Ethernet Switch Modules to communicate with higher speed

Ethernet Switch Modules, by requesting that the higher speed Ethernet Switch Module refrains

from sending packets. Transmissions are temporarily halted to prevent buffer overflows.

For information on configuring Flow Control for ports or LAGs, see "Defining Port Parameters" or

"Defining LAG Parameters."

Back Pressure Support

On half-duplex links, the receiving port prevents buffer overflows by occupying the link so that it is

unavailable for additional traffic.

For information on configuring Back Pressure for ports or LAGs, see "Defining Port Parameters" or

"Defining LAG Parameters."

Jumbo Frames Support

Jumbo frames are frames with an MTU size of up to 10K bytes, and better utilize the network by

transporting the same data using less frames.

The main benefits of this facility are reduced transmission overhead, and reduced host processing

overhead. Jumbo are used for server-to-server transfers.

For information on enabling Jumbo Frames, see "Configuring System Information."
