Configuring DHCP failover
Making two DHCP servers communicate with one another in order to provide redundancy and high availability is termed as DHCP failover. It can be configured by right-clicking on any existing scope and then pressing Configure Failover…
A DHCP Failover intro window appears which gives basic info. It also allows you to select any specific scope or leave it as default (select all). Then click next
In the Specify the partner server to use for the failover page, add or search for the second server that will be part of the DHCP Failover feature, and click Next

All changes that you made will be displayed. Click on Finish, and a new dialog box with the status of each task will be displayed.
You are done. On the second DHCP server could be seen the copied scope.
MAC binding in the DHCP server
Security is one of the biggest concerns in any company or organization. Static MAC binding can allow the network administrator to identify the user so that any user cannot harm the network anonymously.
The steps to configure MAC binding are as follows:
In any desired scope right click on reservations and choose new reservation.
Now a window pops up. Here enter the reservation name, IP address, MAC address, and description, and in the end select supported types both. Click Add.
Your static MAC address is bonded successfully now every user is well-recognized by the network administrator.
