What Can I Do If the Alarm "The number of ARP exceeded the warning threshold" Is Generated on the Device?

What Can I Do If the Alarm "The number of ARP exceeded the warning threshold" Is Generated on the Device?

If the alarm The number of ARP exceeded the warning threshold is generated on the device, the number of used ARP forwarding resources has exceeded a specified alarm threshold.

Depending on the number of remaining ARP forwarding resources on the device, this alarm can be generated in either of the following situations, as indicated by different message digests:
  • If the message digest is hwBoardResWarningThresholdExceed_active, the number of remaining ARP forwarding resources on the device is insufficient. The number of used forwarding resources has exceeded the alarm threshold 75%.

    Dec  6 2017 04:30:43-08:00 DC08-CR03 %%01FEI/4/hwBoardResWarningThresholdExceed_active(l):CID=0x807f042c-alarmID=0x095e2029;The number of forwarding resources reaches the alarm threshold. (Slot = 1, Threshold = 75, Reason = 174, Description : The number of ARP exceeded the warning threshold.)
  • If the message digest is hwBoardResThresholdExceed_active, the remaining ARP forwarding resources on the device are about to be exhausted. The number of used forwarding resources has exceeded the alarm threshold 90%.

    Dec  6 2017 02:35:43-08:00 DC08-CR03 %%01FEI/2/hwBoardResThresholdExceed_active(l):CID=0x807f042c-alarmID=0x095e2022;The number of forwarding resources reaches the alarm threshold. (Slot = 1, Threshold = 90, Reason = 174, Description : The number of ARP exceeded the warning threshold.)
If the alarm The number of ARP exceeded the warning threshold is generated on the device, use either of the following methods to clear the alarm:
  • Increase the number of ARP forwarding resources supported by the device.

    • For the CE12800, CE6870EI, and CE6875EI, if MAC addresses corresponding to ARP entries are contiguous, run the arp resource-mode extend command in the system view to set the ARP resource allocation mode to extend.
    • For the CE12800E equipped with CEL24XSED-E, CEL48XSED-E, CEL24LQED-E, CEL36LQED-E, or CEL36CQFD-X cards, CE5855EI, CE6850HI, CE6850U-HI, CE6851HI, CE6855HI, CE6856HI, CE6857EI, CE6860EI, CE6865EI, CE7850EI, CE7855EI, CE8850EI, CE8860EI, CE8861EI, and CE8868EI, run the system resource large-arp command in the system view to set the system resource mode to large-arp.
  • Reduce the usage of ARP forwarding resources on the device.

    Properly plan network deployment, reduce the number of terminals connected to the device, and prevent all Layer 3 packets from being forwarded by the device. These measures help reduce the number of ARP entries learned by the device.
