Configuring dynamic address allocation for an extended address pool
After the assignable IP address range and the mask are specified, the address pool becomes valid.
Extended address pools support dynamic address allocation only. Excluded IP addresses specified with the forbidden-ip command in DHCP address pool view are not assignable in the current extended address pool, but are assignable in other address pools.
