DHCP. Give IP in function of the Physical Port.

RouterOS Scripting
1

I need to Ip as a function of physical port that I connect. example:

My network is 192.168.1.x/24

if I connect on port 5, I want that computer IP 192.168.1.5
if I connect on port 3, I want that computer IP 192.168.1.3

Where to write the script for the DHCP-Server deliver the IP I want? Any idea?

thank you very much

Why do that?

I have 175 users in a network, all on cable and connect directly to switch. When I have any problem witch cable, it´s so dificult detect the cable on Switch. If I could do fix the Ip-user with the port-fisic, I resolve this problem.

Very hard to do…

I have some ideas about VLAN bridged on each port of each switch, and finally all the VLAN on gateway on same bridge… [and only one DHCP]
Whit this you can trace exactly the source port reading on sniffer the vlan id source…

But is too complicated, I can not help you.



You can not simply sniff traffic on each switch?

Now, I only have this idea:

On each CRS125-24G:
One dhcp-server each port/interface, one IP per pool with reply-arp only activated.

It´s a lot of work and it´s not elegant way to do it.

I hope a better way exist from CCR1016, just only one dhcp-server!!.
