How to Unbind a Static IP and Troubleshoot Network Issues on Huawei Devices
This guide explains how to remove a static IP binding, clear ARP caches, and perform network checks such as loop detection, CPU usage monitoring, and log inspection to resolve persistent IP usage errors on Huawei equipment.
To unbind a static IP address on a Huawei device, first clear the ARP cache and then remove the binding.
reset arp dynamic ip 192.168.20.119 undo static-bind ip-address 192.168.20.119
Additional related commands include setting up IP pools:
ip pool pool 2 static-bind ip-address 192.168.20.119 mac-address XXXX-XXXX-XXXX ip pool pool20
After unbinding, verify the network for possible loops and high resource usage. Use display interface brief to check port utilization and look for loops.
Monitor CPU load with display cpu-usage to ensure the device is not overloaded.
Inspect logs for dropped packets or attacks using display logbuffer and display cpu-defend .
