1. Run the display arp statistics command to view ARP entry statistics on the device and check whether there are more static ARP entries or dynamic ARP entries.

• If there are more dynamic ARP entries, go to Step 2.
• If there are more static ARP entries, go to Step 3.

2. Run the display arp all command to identify the interface that has more ARP entries. Then run the display arp interface command to check ARP entries on the interface and determine whether these ARP entries are necessary for the interface.

• If these ARP entries are necessary, go to Step 5.
• If these ARP entries are not necessary, run the reset arp command to delete certain ARP entries (without system running being affected) and go to Step 4.

3. Run the display current-configuration command to view static ARP entries and check whether these static ARP entries are necessary.

• If these static ARP entries are necessary, go to Step 5.
• If these static ARP entries are not necessary,run the undo arp static command to delete certain static ARP entries (without system running being affected) or run the reset arp static command to clear all static ARP entries. Then go to Step 4.

4. Run the display arp statistics command to check whether the number of ARP entries still continuously increases unexpectedly.

• If the number of ARP entries does not continuously increase unexpectedly, go to Step 6.
• If the number of ARP entries still continuously increases unexpectedly, go to Step 5.

5. Collect the alarm information, log information, and configuration information, and contact Huawei technical support engineers.
