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.
-
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%.

-
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%.

-
Increase the number of ARP forwarding resources supported by the device.
- For the CE12804, CE12808, CE12812, CE12816, CE12804S, CE12808S, 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/CEL36LQED-E/CEL36CQFD-X series cards, CE5855EI, CE6850HI, CE6850U-HI, CE6851HI, CE6855HI, CE6856HI, CE6860EI, CE6865EI, CE7850EI, CE7855EI, CE8850EI, and CE8860EI, 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.
