DHCP Server Multiple Subnet


The DHCP Server Multiple Subnet feature enables multiple disjoint subnets to be configured under the same DHCP address pool. This functionality enables the DHCP server to manage additional IP addresses by adding the addresses to the existing DHCP address pool (instead of using a separate address pool). Multiple subnets in a DHCP address pool can occur along with or instead of managing individual client addresses.

See the "DHCP Features Roadmap" for information about which release trains support DHCP features.
