Hi @iniestha.aung ,

 

Do you know why DHCP conflicts are generated? Maybe the cause can be avoided.

For example, if the conflict is with an IP that is statically assigned, you could exclude it with the command ip dchp excluded-address <ip>

 

Regards

 

Hi Cisco,



I have excluded some ip and as I check with user, they are saying they didn't assign static ip in their device.

Router#sh run | i ip dhcp exclude

ip dhcp excluded-address 192.168.1.1 192.168.1.99

ip dhcp excluded-address 10.10.8.1 10.10.8.20



Below is log :

*Apr 15 06:51:34.379: %DHCPD-4-DECLINE_CONFLICT: DHCP address conflict: client 0168.dbca.9ebc.2f declined 10.10.11.40.

My temporary solution right now is clear ip conflict when users are having issue.



Thank you.
