2-5Enabling the Global Address Pool Mode on Interface(s)You can configure the global address pool mode on the specified or all interfaces of a DHCP server.After that, when the DHCP server receives DHCP packets from DHCP clients through these interfaces,it assigns IP addresses in the global address pool to the DHCP clients.Follow these steps to configure the global address pool mode on interface(s):To do… Use the command… RemarksEnter system view system-view —interface interface-typeinterface-numberdhcp select globalConfigure thecurrent interfacequitConfigure thespecifiedinterface(s) orall theinterfaces tooperate inglobal addresspool modeConfigure multipleinterfacessimultaneously insystem viewdhcp select global { interfaceinterface-type interface-number [ tointerface-type interface-number ] |all }OptionalBy default, theinterface operatesin global addresspool mode.Creating a DHCP Global Address PoolFollow these steps to create a DHCP address pool:To do… Use the command… RemarksEnter system view system-view —Create a DHCP global address pooland enter its viewdhcp server ip-poolpool-nameRequiredNot created by default.Configuring an Address Allocation Mode for the Global Address PoolYou can configure either the static IP address allocation mode or the dynamic IP address allocationmode for a global address pool, and only one mode can be configured for one DHCP global addresspool.For dynamic IP address allocation, you need to specify the range of the IP addresses to be dynamicallyassigned. But for static IP address binding, you can regard that the IP address statically bound to aDHCP client comes from a special DHCP address pool that contains only one IP address.Configuring the static IP address allocation modeSome DHCP clients, such as WWW servers, need fixed IP addresses. This can be achieved by bindingIP addresses to the MAC addresses of these DHCP clients. When such a DHCP client requests an IP
