Haryortheyji,

 

You can use the following show commands in EXEC Privilege mode to get that information. In order to get the log messages for all DHCP packets sent and received on DHCP client interfaces you would use the debug ip dhcp client packets [interface type slot/port[/subport] command.

 

To display log message on DHCP client interfaces for IP address acquisition, IP address release, IP address and lease time renewal, and release an IP address, use the [no] debug ip dhcp client events [interface type slot/port[/subport]] command.

 

Let me know if this helps.

These are the errors I get. I'd like to let you know that the ip helper address is not configured on the individual interfaces. Also there is no any option when I use the help after the debug command.

debug ip dhcp client events eth1/1/1
% Error: Unrecognized command.

debug ip dhcp client events int eth1/1/1
% Error: Unrecognized command.

debug ip dhcp client packets int 1/1/1
% Error: Unrecognized command.

Thanks Young!. To clarify things without the DHCP snooping configuration, the debug commands mentioned by Chris will not work. 

No Events found!
