ARP/4/hwEthernetARPLimitExceed_active

ARP/4/hwEthernetARPLimitExceed_active

Message

ARP/4/hwEthernetARPLimitExceed_active: The number of ARP entries learned on the interface exceeded the threshold. (Interface name=[InterfaceName], Maximum number of ARP entries=[LimitNumber], Number of learned ARP entries=[LearnedNumber])

Description

The number of dynamic ARP entries learned on the interface exceeded the threshold.

Parameters

Parameter Name Parameter Meaning

Interface name

Interface name

Maximum number of ARP entries

Maximum number of dynamic ARP entries that an interface can learn

Number of learned ARP entries

Number of dynamic ARP entries that an interface has learned

Possible Causes

The number of dynamic ARP entries learned on the interface exceeded the specified threshold.

Procedure

  1. Check whether the arp limit and arp limit alarm-threshold commands need to be run.

    • If the commands do not need to be run but have been run, run the undo arp limit and undo arp limit alarm-threshold commands to disable the ARP entry limit function.
    • If the commands need to be run, go to 2.

  2. Check whether the values of maximum and threshold-value specified using the arp limit and arp limit alarm-threshold commands are too small.

    • If the values are too small, run the arp limit command to increase the maximum number of dynamic ARP entries that the interface can learn, or run the arp limit alarm-threshold command to increase the alarm threshold for the maximum number of dynamic ARP entries that the interface can learn.
    • If the values are not too small, go to 3.

  3. Run the display arp interface command to check whether the ARP entries learned on a specified interface are needed.

    • If the ARP entries are needed, go to 5
    • If the ARP entries are not needed, run the reset arp command to clear the ARP entries without interrupting services, and then go to 4.

  4. Run the display arp statistics command to check whether the total number of ARP entries on the device is increasing.

    • If the number of ARP entries is not increasing, go to 6.
    • If the number of ARP entries is increasing, go to 5.

  5. Collect log information and configuration information, and then contact technical support personnel.
  6. End.
