Example: Configuring Manual Bindings
The following example shows how to create a manual binding for a client named example1.abc.com that
sends a client identifier in the DHCP packet. The MAC address of the client is 02c7.f800.0422 and the
IP address of the client is 172.16.2.254.
Switch(config)# ip dhcp pool pool1
Switch(dhcp-config)# host 172.16.2.254
Switch(dhcp-config)# client-identifier 01b7.0813.8811.66
Switch(dhcp-config)# client-name example1
The following example shows how to create a manual binding for a client named example2.abc.com that
does not send a client identifier in the DHCP packet. The MAC address of the client is 02c7.f800.0422
and the IP address of the client is 172.16.2.253.
Switch(config)# ip dhcp pool pool2
Switch(dhcp-config)# host 172.16.2.253
Switch(dhcp-config)# hardware-address 02c7.f800.0422 ethernet
Switch(dhcp-config)# client-name example1
Because attributes are inherited, the two preceding configurations are equivalent to the following:
Switch(config)# ip dhcp pool pool1
Switch(dhcp-config)# host 172.16.2.254 255.255.255.0
Switch(dhcp-config)# hardware-address 02c7.f800.0422 ieee802
Switch(dhcp-config)# client-name client1
Switch(dhcp-config)# default-router 172.16.2.100 172.16.2.101
Switch(dhcp-config)# domain-name abc.com
Switch(dhcp-config)# dns-server 172.16.1.102 172.16.2.102
Switch(dhcp-config)# netbios-name-server 172.16.1.103 172.16.2.103
