Configuration Examples
This section provides the following configuration examples:
•
DHCP Database Agent Configuration Example
•
DHCP Address Pool Configuration Example
•
Manual Bindings Configuration Example
DHCP Database Agent Configuration Example
The following example stores bindings on host 172.16.4.253. The file transfer protocol is FTP. The
server should wait 2 minutes (120 seconds) before writing database changes.
ip dhcp database ftp://user:[email protected]/router-dhcp write-delay 120
DHCP Address Pool Configuration Example
In the following example, three DHCP address pools are created: one in network 172.16.0.0, one in
subnetwork 172.16.1.0, and one in subnetwork 172.16.2.0. Attributes from network 172.16.0.0, such
as the domain name, DNS server, NetBIOS name server, and NetBIOS node type, are inherited in
subnetworks 172.16.1.0 and 172.16.2.0. In each pool, clients are granted 30-day leases and all
addresses in each subnetwork, except the excluded addresses, are available to the DHCP server for
assigning to clients. Table 1 lists the IP addresses for the devices in three DHCP address pools.
Command Purpose
Router> show ip dhcp binding [address] Displays a list of all bindings created on a specific DHCP
server.
Router> show ip dhcp conflict [address] Displays a list of all address conflicts recorded by a specific
DHCP server.
Router# show ip dhcp database [url] Displays recent activity on the DHCP database.
Note Use this command in privileged EXEC mode.
Router> show ip dhcp server statistics Displays count information about server statistics and mes-
sages sent and received.
