Select this option to have the Switch detect if the configured rate limit for

 

specific control packets 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 shuts down the port.

 

• 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
