DHCP Set Up Overview Chapter 12
Configuring DHCP
 Use ip dhcp ping timeout to specify the period the server must wait
before timing out a ping request.
 Monitor and maintain DHCP Server services by issuing the following
show commands. Show ip dhcp bindings displays bindings data on
the DHCP Server including lease expiration dates.
Show ip dhcp
conflict displays address conflicts found by a DHCP Server when
addresses are offered to the client.
Show ip dhcp server
statistics is a useful catch-all command. Show ip local pool
shows a list of active IP local pools, excluded and in use IP addresses.
DHCP Set Up Overview
Configuring DHCP Address Pools
The DHCP Server is configured by performing the following:
 Allocate one or more address pools for DHCP clients. These pools can
specify addresses on the local subnets of the router or external
subnets whose clients reach the DHCP Server using BOOTP Relay.
 Exclude any addresses from these pools which must restricted and
map to the DHCP pool.
 For each pool, define the set of DHCP network configuration
parameters to be supplied to clients.
 Add manual (static) bindings to the DHCP pool configuration.
 Enable the DHCP Server on a FastEthernet interface only.
Configuring DHCP - Network Configuration Parameters
The DHCP Server can supply network configuration parameters; e.g., the IP
address of the DNS Server to its clients.
A DHCP client may require a large set of configuration parameters. Likewise,
a network may contain a variety of different client types, each needing a
different (possibly unique) set of network parameters.
The XSR’s DHCP setup is minimized for elaborate configuration by the use of
scopes.
