3.7 Configuration Examples

DHCP configuration examples explain the networking requirements, networking diagram,
configuration notes, configuration roadmap, and configuration procedure. The configuration
examples involve various usage scenarios of DHCP.
3.7.1 Example for Configuring a DHCP Server Based on the Global
Address Pool
This section describes how to configure a global address pool to allocate IP addresses for clients
when the clients and DHCP server are in the same network segment.
Networking Requirements
An enterprise has two offices that are in the same network segment. To reduce network
construction cost, the enterprise uses one DHCP server to allocate IP addresses for the computers
in the two offices.
As shown in
user access switches. A global address pool or an interface address pool can be configured on
SwitchA. This section describes how to configure a global address pool. Address pool
10.1.1.0/24 consists of two network segments: 10.1.1.0/25 and 10.1.1.128/25. The IP addresses
of the VLANIF interfaces on the DHCP server are 10.1.1.1/25 and 10.1.1.129/25.
There are a few computers in network segment 10.1.1.0/25 and the computer locations are fixed.
The lease of an IP address in 10.1.1.0/25 is 10 days, the DNS address is 10.1.1.2, no NetBIOS
address is set, and the IP address of the egress gateway is 10.1.1.126.
There are many computers in network segment 10.1.1.128/25 and the computers are often moved
from one place to another. The lease of an IP address in 10.1.1.128/25 is 2 days, the DNS address
is 10.1.1.2, the NetBIOS address is 10.1.1.4, and the IP address of the egress gateway is
10.1.1.254.
