Configuration guidelines
When you configure ARP automatic scanning and fixed ARP, follow these guidelines:
The interface view can be Layer 3 Ethernet interface view, VLAN interface view, Layer 3 aggregate interface view.
IP addresses existing in ARP entries are not scanned.
ARP automatic scanning may 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.
Static ARP entries changed from dynamic ARP entries have the same attributes as the manually configured static ARP entries.
Use the arp fixup command to change the existing dynamic ARP entries into static ARP entries. You can use this command again to change the dynamic ARP entries learned later into static ARP entries.
The number of static ARP entries changed from dynamic ARP entries is restricted by the number of static ARP entries that the device supports. As a result, the device may fail to change all dynamic ARP entries into static ARP entries.
To delete a specific static ARP entry changed from a dynamic one, use the undo arp ip-address [ vpn-instance-name ] command. To delete all such static ARP entries, use the reset arp all or reset arp static command.
