Operation Manual – DHCPH3C S7500 Series Ethernet Switches Chapter 2 DHCP Server Configuration2-9DHCP server provides the gateway addresses to DHCP clients as well whileassigning IP addresses to them.You can configure gateway addresses for address pools on a DHCP server. Currently,you can configure up to eight gateway addresses for a DHCP address pool.Follow these steps to configure gateway addresses for DHCP clients:To do… Use the command… RemarksEnter system view system-view —Create a DHCP addresspool and enter DHCPaddress pool viewdhcp server ip-poolpool-nameRequiredBy default, no globalDHCP address pool iscreatedConfigure gatewayaddresses for DHCPclientsgateway-listip-address&<1-8>RequiredBy default, no gatewayaddress is configured2.3 Interface Address Pool-Based DHCP ServerConfigurationCaution:In the interface address pool mode, after the addresses in the interface address poolhave been assigned, the DHCP server picks IP addresses from the global interfaceaddress pool containing the segment of the interface address pool and assigns themto the DHCP clients. As a result, the IP addresses obtained from global address poolsand those obtained from interface address pools are not in the same networksegment, so the clients cannot interoperate with each other.In the interface address pool mode, if the IP addresses in the same address pool arerequired to be assigned to the clients on the same VLAN interface, the number ofclients that obtain IP addresses automatically cannot exceed the number of the IPaddresses that can be assigned in the interface address pool.2.3.1 Configuration OverviewAn interface address pool is created when the interface is assigned a valid unicast IPaddress and you execute the dhcp select interface command in interface view. TheIP addresses contained in it belong to the network segment where the interfaceresides and are available to the interface only.
