IP Duplicity configuration

[Vachy]

Hi.

I got peoblem with IP duplicity messages in the switch. We got 5940. Before was there 7506 on Comware 5. If was some duplicity on network, then comes DUP message in log. But 5940 show nothing. I tryed everything, but was no succesfull. 

What must be configured?

Thank for helping.

Thank you for Answer. This command is still in the config. But the messages did not come. This switch is main router/switch for network. Here is all interfaces for VLANs. Must there be some special config for ARP or Log?

Hi,

By default duplicated address detection eneabled in comware 7.

Are you using DHCP ip assignment, if yes then  use command: 'dhcp client dad enable'

Please refer configuration guide. And if still remains then please log a ticket with support.

Thanks!
