documented in detail in the ExtremeWare Software User Guide or the ExtremeWare Software Command
Reference Guide, unless otherwise noted.

Features Added or Enhanced in ExtremeWare 7.0.1b11
The following features were added or enhanced in ExtremeWare 7.0.1b11:
• You can configure 802.3x flow control on your “
3
” series module. Because these modules are
oversubscribed to the module switch fabric, traffic can congest. Flow control allows you to stop
incoming traffic when too much congestion occurs.
Flow control sends a PAUSE frame to the transmitter when traffic approaches the congestion
threshold for a specific queue. The PAUSE frame is sent before the queue overflows, so throughput is
slightly reduced when flow control is enabled. Flow control is auto-negotiated and is disabled if both
ports do not support it.
