Broadcast Control
In the
Broadcast Control
page, you can enable and disable broadcast control for all ports on the switch.
The
Broadcast Control
page contains the following editable fields:
l
Broadcast Control Status
—
Allows you to enable/disable broadcast storm control for ports on the switch. When enabled, the switch employs a
broadcast-control mechanism if the packet-per-second threshold on a port is exceeded. (The default is enabled.)
l
Threshold
—
The packet-per-second threshold for broadcast packets received on a port. (The default is 500 packets per second.)
