Hello everyone,

I have a NAC solution that uses DHCP relay for device profiling and i want to configure DHCP relay on my cisco C1000 switch with the NAC IP as a secondary ip to sniff packets. how do i go about doing this

thanks

Thanks for your response, i would like to confirm some things

1. 10.1.100.100 does this IP represent the IP of the DHCP server?

2.10.1.200.6 and this the IP of the NAC device

correct the order is not important the interface will send packet to all ip helper-address list.
so dont worry which come first
