Restricting Dynamic ARP Entry Learning
When a large number of ARP entries are generated on a specified interface, you can prevent the interface to dynamically learn ARP entries.
Background Information
If dynamic ARP entry learning is disabled on an interface, traffic forwarding may fail on this interface.
After dynamic ARP entry learning is disabled on an interface, the system will not automatically delete the ARP entries that were learnt previously on this interface. You can delete or retain these dynamic ARP entries as required.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run arp learning disable
Dynamic ARP entry learning is disabled on the interface.
- Run commit
The configuration is committed.
