DHCP Pool Selection – How to Choose a Pool for IP Address Assignment

Well, one way to do this would be to exclude the entire pool from assignment. This would leave the configuration of the pool in there and you would just remove the exclusion if you wanted it to assign addresses again.

ip dhcp excluded-address <first address> <last address>

However, I would just archive a copy of the config and remove the pool.

On a Cisco IOS DHCP server, it is pretty simple. In the DHCP pool configuration, use the address command to assign an IP address to a MAC address:

address <ip-address> hardware-address <mac-address>

Preassigning IP Addresses and Associating Them to a Client:

Preassigning IP Addresses and Associating Them to a Client

Perform this task to preassign an IP address and associate it to a client identified by a client ID or MAC address.

For port-based address assignment, you must perform the task in the Automatically Generating a Subscriber Identifier for a DHCP Message Received on a Port task to associate the client ID with the subscriber ID. The subscriber ID value is based on the short name of the port to which the directly connected device is attached.

Configure a normal DHCP pool by supplying any DHCP options and lease time. Preassigned addresses are automatically excluded from normal dynamic IP address assignment. Preassigned addresses cannot be used in host pools, but there can be multiple preassigned addresses per DHCP address pool.

Note

Only one IP address can be assigned per port.

Preassigned addresses (also called reserved addresses) cannot be cleared by using the clear ip dhcp binding command.

SUMMARY STEPS

1. enable
2. configure terminal
3. ip dhcp pool name
4. network network-number [mask | / prefix-length]
5. address ip-address client-id string [ascii]
6. address ip-address hardware-address mac-address [hardware-number]
7. end
8. show ip dhcp pool [name]
9. show ip dhcp binding
