Operation Manual – DHCP
H3C S3610&S5510 Series Ethernet Switches
The domain name and DNS server address on the subnets 10.1.1.0/25 and
10.1.1.128/25 are the same. Therefore, the domain name suffix and DNS server
address can be configured only for the subnet 10.1.1.0/24. The subnet
10.1.1.128/25 can inherit the configuration of the subnet 10.1.1.0/24.
Note:
In this example, the number of requesting clients connected to VLAN-interface 1 should
be less than 122, and that of clients connected to VLAN-interface 2 less than 124.
