ip arp-throttle remediation-mode

Determines the disposition of ARP packets the switch receives.

Syntax 


ip arp-throttle remediation-mode <monitor | filter>
When ARP throttle is enabled in monitor mode (the default), the switch does the following:

  • Monitors ARP packet traffic received by the switch CPU.

  • Assigns “blacklist” status to devices generating an excessive numbers of ARP packets within a five-second period.

  • Maintains a running total of the devices from which ARP packets are being received.

When ARP throttle is enabled in filter mode, the switch drops all ARP packet traffic received from blacklisted devices while continuing to perform the above three monitor actions.

Example

Configure the switch to drop ARP packet traffic received from blacklisted devices.


switch(config)# ip arp-throttle remediation-mode filter
