Cause

This field displays the types of control packet that may cause CPU 
overload.

*

Use this row to make the setting the same for all entries. Use this row 
first and then make adjustments to each entry if necessary. 

Note: Changes in this row are copied to all the entries as soon as you 

make them.

Active

Select this option to have the Switch detect if the configured rate limit for 
a specific control packet is exceeded and take the action selected below.

Mode

Select the action that the Switch takes when the number of control 
packets exceed the rate limit on a port, set in the Advanced Application 
> Errdisable > CPU protection screen.

• inactive-port - The Switch disables the port on which the control 

packets are received.

• inactive-reason - The Switch bypasses the processing of the 

specified control packets (such as ARP or IGMP packets), or drops all 

the specified control packets (such as BPDU) on the port.

• rate-limitation - The Switch drops the additional control packets the 

port has to handle in every one second.

Apply

Click Apply to save your changes to the Switch’s run-time memory. The 
Switch loses these changes if it is turned off or loses power, so use the 
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.

Cancel

Click Cancel to begin configuring this screen afresh.
