Parameter
interface interface-type interface-number [ to interface-type interface-number ]:
Specifies the interface(s) to operate in global address pool mode. The interface-type
and interface-number arguments are the type and number of an interface. The to
keyword separates the start and the end of an interface range.
all: Specifies all ports to operate in global address pool mode.
Description
Use the dhcp select global command to configure the specified interface(s) or all
interfaces to operate in global DHCP address pool mode. Upon receiving a DHCP
packet from a DHCP client through an interface operating in global DHCP address
pool mode, the DHCP server chooses an IP address from a global DHCP address pool
of the local DHCP server and assigns the address to the DHCP client.
Use the undo dhcp select global command to restore the default DHCP packet
processing mode.
By default, an interface operates in local DHCP server global address pool mode.
Example
# Configure all interfaces to operate in global DHCP address pool mode, so that when
a DHCP packet is received from a DHCP client through any interface, the DHCP
server assigns an IP address in local global DHCP address pools to the DHCP client.
