DHCP Scope

DHCP scope is a well-defined term in DHCP arena. It is used to define a policy for giving out IP addresses and other options to host on a specific IP subnet. In DCNM, we use the DCHP scope to distribute IPv4 address, PYTHON bootscript, (or other supported protocol + access credential + server, for example; http://<dcnm-server-ip>/scripts) which stores the bootscript.

From the menu bar, select Config>Power-On Auto Provisioning (POAP)>DHCP Scope.
