How to Troubleshooting if an IP address conflict was reported on the device?

Topology:
EG3250-->PoE Switch-->AP820-L(v3)-->end users
Troubleshooting procedure:
1.Verify the true network topology
2.Check the number of connections and whether the configured DHCP address pool is sufficient. (If the number of IP addresses configured in the DHCP address pool is lower than the number of users using the address pool, IP address conflicts will happen in some of the users, or some users fail to obtain addresses)
3.Check whether the DHCP server assigns static addresses to certain devices, or some users use the IP addresses in the DHCP server as static addresses.


Configuration Commands:
Ruijie#show ip dhcp pool
Ruijie#show ip dhcp binding
Input the CLI commands in the Cloud:






Input the CLI commands in the CLI interface:



4. Result:
If the terminal is manually bound to a static IP address on the DHCP server, it will need to change the terminal to obtain the ip address dynamically. If users cannot find the terminal obtained the ip address statically. Users can only change the static IP address bound to the device in the list to another IP address.
