Global Configuration

This option allows you to configure the global port control registers.
Half Duplex Back Pressure Flow:
Compex SAS2224B supports two backpressure flow control scheme to force incoming
packet back off after the switch destination port is congested. This means that when A
sends packets to B continuously, the latter might not be able to receive all packets on
time. As a result, some of the packets will be dropped. Upon enabling this option, B will
send out a packet, informing A to slow down the progress in transmitting the packets.
Broadcast Storm Filtering Control:
Enabling this option will allow each port to drop broadcast packets after a continuous
received broadcast packets counter up to 64 count. The counter will be reset to 0 every
800ms or when receiving any non-broadcast packets.
Loop Detect:
Compex SAS2224B provides loop-detecting function to alarm a network loop existing
via the diagnostic section (Section 5.3).
