CAUTION:
In the interface address pool mode, after the addresses in the interface
address pool have been assigned, the DHCP server picks IP addresses from the
global interface address pool containing the segment of the interface address pool
and assigns them to the DHCP clients. As a result, the IP addresses obtained from
global address pools and those obtained from interface address pools are not in
the same network segment, so the clients cannot interoperate with each other.
In the interface address pool mode, if the IP addresses in the same address pool
are required to be assigned to the clients on the same VLAN interface, the number
of clients that obtain IP addresses automatically cannot exceed the number of the
IP addresses that can be assigned in the interface address pool.
Configuration Overview
An interface address pool is created when the interface is assigned a valid unicast
IP address and you execute the
dhcp select interface
command in interface view.
The IP addresses contained in it belong to the network segment where the
interface resides and are available to the interface only.
You can perform certain configurations for DHCP address pools of an interface or
multiple interfaces within specified interface ranges. Configuring for multiple
interfaces eases configuration work load and makes you to configure in a more
convenient way.
