Dynamic Host Configuration Protocol (DHCP)
Configuring a DHCP Server
The command line interface (CLI) displays Configuring New Pool “<pool-
name>” and moves you into the DHCP server pool configuration mode
context.
You can also edit a pool with the same command. The CLI displays
Configuring Existing Pool “<poolname>”.
You can create multiple DHCP server address pools to provide configurations
to different segments of the network. If the subnets are contiguous, you can
create a parent pool with global settings for all subnets and separate child
pools, each with settings particular to an individual subnet. (See “Configuring
Parent and Child Pools” on page 13-13.)
From the DCHP server address pool configuration mode context, you
configure:
■ subnet address
■ default gateway address
■ lease time
■ DNS server addresses
■ WINS server addresses
■ domain name
Every pool must include a subnet address, default gateway, and lease time.
You can accept the default lease time (1 day), but you must configure the
subnet address and default gateway. You should also configure at least one
DNS server.
Specifying the Network Address and Subnet Mask
You assign a subnet to the DHCP server address pool by specifying the
network address and subnet mask:
Syntax: network <network A.B.C.D> <subnet mask | /prefix length>
For example, to specify a private Class C subnet:
ProCurve(config-dhcp)# network 192.168.1.0 255.255.255.0
The DHCP server on the ProCurve Secure Router supports Classless Inter-
Domain Routing (CIDR) addresses, so you can enter a bit length for the
network address rather than a subnet mask. For example, your organization
may have divided the Class B network 172.16.0.0 into sixteen subnets, includ-
ing 172.16.32.0 /20 and 172.16.48.0 /20. For the first DHCP pool, you would
enter:
ProCurve(config-dhcp)# network 172.16.32.0 /20
