Network requirementsAs shown in Figure 9-10,z The DHCP server is connected to the DHCP client and the RADIUS serverthrough interface Ethernet1/0/0 and Ethernet1/0/1 respectively.z The IP address of the RADIUS server is 10.1.2.2/24.z DHCP accounting is enabled on the DHCP server. The global DHCP address poolis 10.1.1.0 and domain 123 is assigned to the pool for DHCP accounting.It is required that the RADIUS accounting server could track IP address use of theDHCP client.II.
