You can protect your network from broadcast storms by setting a threshold for
broadcast traffic for each port. Any broadcast packets exceeding the specified
threshold will then dropped. (Broadcast Storm Control is enabled by default.)
Use this command to configure broadcast storm control. Use the no form
to disable broadcast storm control.
Syntax
switchport broadcastpacket-raterate no switchport broadcast
rate - Threshold level as a rate; i.e., packets per second.
(Range - PowerConnect 5224: 16, 64, 128, 256; PowerConnect 3248: 500 - 262143)
Default Setting
PowerConnect 5224: 256 packets per second
PowerConnect 3248: 500 packets per second
Command Mode
Interface Configuration (Ethernet)
Command Usage
When broadcast traffic exceeds the specified threshold, packets above that
threshold are dropped.
This command can enable or disable broadcast storm control for the selected
interface. However, the specified threshold value applies to the entire switch.
Enabling jumbo frames for the PowerConnect 5224 will limit the maximum threshold
for broadcast storm control to 64 packets per second. (See the jumbo
frame command.)
Example
The following shows how to configure broadcast suppression at 64 packets
per second on port 5:
