You can use the display dhcp server ip-in-use command on the DHCP server to view the IP addresses
assigned to the clients.
Dynamic IP address assignment configuration example
Network requirements
•
As shown in
, the DHCP server (SecPath) assigns IP address to clients on subnet
10.1.1.0/24, which is subnetted into 10.1.1.0/25 and 10.1.1.128/25.
•
The IP addresses of GigabitEthernet 0/1 and GigabitEthernet 0/2 on the SecPath are 10.1.1.1/25
and 10.1.1.129/25 respectively.
•
In subnet 10.1.1.0/25, the address lease duration is ten days and twelve hours, domain name suffix
aabbcc.com, DNS server address 10.1.1.2/25, WINS server address 10.1.1.4/25, and gateway
address 10.1.1.126/25.
•
In the subnet 10.1.1.128/25, the address lease duration is five days, domain name suffix
aabbcc.com, DNS server address 10.1.1.2/25, and gateway address 10.1.1.254/25 and there is
no WINS server address.
•
The domain name suffix and DNS server address on subnets 10.1.1.0/25 and 10.1.1.128/25 are the
same. Therefore, the domain name suffix and DNS server address need to be configured only for
subnet 10.1.1.0/24. Subnet 10.1.1.0/25 and 10.1.1.128/25 can inherit the configuration of subnet
10.1.1.0/24.
