The arp learning disable command disables an interface from learning dynamic ARP entries.
The undo arp learning disable command enables an interface to learn dynamic ARP entries.
By default, an interface is enabled to learn dynamic ARP entries.
Usage Scenario
To ensure security and facilitate management, you can enable an interface to learn or disable an interface from learning dynamic ARP entries. You can also use the arp learning strict or arp learning strict commands to strictly control ARP entry learning on an interface.
Precautions
If an interface is disabled from learning ARP entries, the network will be interrupted.
If an interface has learned some dynamic ARP entries, the system does not delete these entries after the interface is disabled from learning dynamic ARP entries. You can manually delete or reserve these learned dynamic ARP entries (deleted by the reset arp command).
