Flow Control
—When there is a great deal of traffic on the wireless LAN, flow
control can prevent bridge input buffers from overflowing, thereby increasing
WLAN reliability. The bridge supports IEEE 802.3x asymmetric outgoing flow
control, allowing it to pause the transmission of data frames from a switch or
router that is operating in full-duplex mode and supports 10/100
