Example Dhcp Pool Configuration; Assigning A Fixed Address To A Host Through A Dhcp Server - HP ProCurve Secure 7000dl Series Basic Management And Configuration Manual

Dynamic Host Configuration Protocol (DHCP)
Configuring a DHCP Server
13-14
You do not specify a default router for a parent pool.
You configure the child pools just as you do any DHCP pool, but you only have
to configure the subnet address and default router. If you alter a setting, such
as the lease time, the configuration in the child pool overrides that in the
parent pool.

Example DHCP Pool Configuration

In Figure 13-3, a router connects to two subnets. The figure also shows the
network's DNS and WINS servers. This LAN reserves addresses 1 to 29 on each
subnet for various network devices, such as routers, switches, and servers. To
configure this router to act as a DHCP server for its local subnets, you would
complete these steps:
1. Exclude static addresses:
ProCurve(config)# ip dhcp-server excluded-address 192.168.1.1 192.168.1.29
ProCurve(config)# ip dhcp-server excluded-address 192.168.2.1 192.168.2.29
2. Create the parent pool with global settings:
ProCurve(config)# ip dhcp-server pool Parent
ProCurve(config-dhcp)# network 192.168.0.0 /16
ProCurve(config-dhcp)# dns-server 192.168.1.25 192.168.2.23
ProCurve(config-dhcp)# netbios-name-server 192.168.2.26
ProCurve(config-dhcp)# lease 0 12
3. Create the child pools, each with its own subnet and default gateway:
ProCurve(config-dhcp)# ip dhcp-server pool LAN1
ProCurve(config-dhcp)# network 192.168.1.0 /24
ProCurve(config-dhcp)# default-router 192.168.1.1
ProCurve(config-dhcp)# ip dhcp-server pool LAN2
ProCurve(config-dhcp)# network 192.168.2.0 /24
ProCurve(config-dhcp)# default-router 192.168.2.1
Assigning a Fixed Address to a Host through a DHCP
Server
Certain devices should almost always be given static addresses so that routes
remain accurate, the network design logical and consistent, and the traffic
flow uninterrupted. However, sometimes such a device is also required to take
a dynamic address from a DHCP server. You can configure the router to assign
a fixed DHCP address to this device.
