You can use the display dhcp server ip-in-usecommand on the DHCP server to view the IP addresses assigned to the clients.Troubleshooting DHCP server configurationSymptomA client's IP address obtained from the DHCP server conflicts with another IP address.AnalysisAnother host on the subnet might have the same IP address.Solution1. Disable the client's network adapter or disconnect the client's network cable. Ping the IP addressof the client from another host to check whether there is a host using the same IP address.2. If a ping response is received, the IP address has been manually configured on a host. Execute thedhcp server forbidden-ip command on the DHCP server to exclude the IP address from dynamicallocation.
