The mac-change notify-arp disable command disables association between MAC and ARP.
The undo mac-change notify-arp disable command enables association between MAC and ARP.
By default, association between MAC and ARP is enabled.
Usage Scenario
A device supports association between MAC and ARP by default. Association between MAC and ARP is generally deployed on the gateway and applies to networks where multiple links are available between the user and gateway or the interface through which users access the gateway can change. After association between MAC and ARP is configured, ARP entries can be rapidly updated to ensure stable traffic forwarding. However, the ARP entries learned by the VLANIF interface are synchronized globally, causing the number of ARP entries on all interface boards to increase. To resolve this problem in scenarios where ARP entries learned by the VLANIF interface do not need to be synchronized globally, run the mac-change notify-arp disable command to disable association between MAC and ARP.
Precautions
Running the mac-change notify-arp disable command causes ARP entries on the VLANIF interface to be reset, which may cause traffic forwarding failures. Therefore, exercise caution when running this command.
