Configuration Examples
To display DHCP server information, use the following commands in EXEC mode, as needed:
Command
Router> show ip dhcp binding [address]
Router> show ip dhcp conflict [address]
Router# show ip dhcp database [url]
Router> show ip dhcp server statistics
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:password@172.16.4.253/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.
