Configuration restrictions and guidelines
Follow these restrictions and guidelines when you configure ARP scanning and fixed ARP:
IP addresses in existing ARP entries are not scanned.
ARP scanning will take some time. To stop an ongoing scan, press Ctrl + C. Dynamic ARP entries are created based on ARP replies received before the scan is terminated.
The arp fixup command is a one-time operation. You can use this command again to convert the dynamic ARP entries learned later to static.
Due to the limit on the total number of static ARP entries, some dynamic ARP entries might fail the conversion.
To delete a static ARP entry converted from a dynamic one, use the undo arp ip-address [ vpn-instance-name ] command. Use the reset arp all command to delete all ARP entries or the reset arp static command to delete all static ARP entries.
