I will set 2 dhcp servers on 1 ethernet port, if dhcp server1 failed take dhcp server2 over.
see printscreens what i done: If i disable dhcp server 1 as test) and restart computer, give dhcp2 server not ip adresses.
What do i wrong?
Sorry for my bad englisch

I don’t understand what the point of that would be. I can see adding a second physical device, but why would you want two DHCP server instances on the same physical device?

for a redundant network if dhcp server1 failed take the second dhcp it over.

That only makes sense when you have two different physical devices. Having two DHCP servers on the same router on the same interface does absolutely nothing to improve redundancy. If the router dies, both DHCP servers are dead. If the interface does, both DHCP servers are dead. If the DHCP server process does, both DHCP servers are dead.

I understand, thanks for your answer.
