Global Features
7.2.3.6.1
Broadcast Storm Control
The EISC can enable or disable broadcast storm filtering. When enabled, each port will
drop broadcast packets — those with a Destination MAC ID of FF FF FF FF FF FF — after
receiving 64 continuous broadcast packets. The counter will be reset to 0 every 800 ms
or on receiving a packet with a Destination MAC ID other than FF FF FF FF FF FF.

7.2.3.6.2
Backpressure Flow Control
Backpressure flow control is applied globally — affecting all half-duplex ports or none. If
this feature is disabled, the destination of the incoming packet is checked and, if found
to be congested, the packet is discarded to avoid blocking the packet stream.
(applying to ALL ports)
