SUMMARY STEPS
1. Modify the basic configuration script provided by Cisco or create your own script.
2. Deploy a DHCP server and configure it with the interface, gateway, and TFTP server IP addresses and a
bootfile with the path and name of the configuration script file. (This information is provided to the switch
when it first boots.)
3. Deploy a TFTP or HTTP server to host the configuration script.
4. Deploy one or more servers to host the software images and configuration files.

not all the DHCP server including IOS DHCP server sends the DHCP responses to 255.255.255.255,
NX-OS is unable to get an IP address as a result POAP does not succeed.
fabricpath interface is converted to classical Ehternet (CE). The neighbor (transit) nodes uses the poap
transit configuration for the initial traffic. This command was introduced in Cisco NX-OS Release
7.0(0)N1(1) and is used in global configuration mode. By default, this command is enabled on devices
running 7.x images. To disable the poap transit command, use the no poap transit command.
