Description
Using the dhcp select command in system view, you can select a method for
multiple interfaces in a specified range to dispose the DHCP packets destined to
the local device. Using the undo dhcp select command in system view, you can
restore the default setting.
By default, DHCP packets destined to the local device will be sent to the internal
server and the clients sending them will be allocated with addresses selected from
a global address pool (in global approach).
For the related command, see dhcp select (in interface view).
Example
Configure the interfaces in the range of Ethernet2/0/0.1 to Ethernet2/0/0.5 to
allocate addresses selected from an interface address pool maintained by the
internal server to the clients sending DHCP packets destined to the local device.
