IP and MAC binding

Sangamesh — Tue, 18 Feb 2020 14:05:37 GMT

My configuration is

configure iparp 10.10.10.1 vr VR-Default <MAC add>.

My requirement is

If I change the IP address of that particular device. It should not work means it should not PING.

How do I do that? I only want to allow particular IP from particular MAC address.

Hello do you know the ip address you want to not allow to ping? You are going to have to go into the Dhcp server and exclude it.

My requirement is, I only want to allow only one IP address for one MAC. If I change IP for that particular MAC it should not PING.

You might be able to use access lists for this. The logic

if ethernet-source-address 00:01:02:03:04:00 and source-address 1.1.1.1 then permit else deny. Play with policies.

What are you hoping to achieve as there may be a better way to look at it. Would it be enough to pin an IP address to a specific MAC within DHCP, or to hard set the host and exclude the address from DHCP scope?
