Logging dhcp bindings

[Rosa Ladeira]

I have configured a DHCP server running on Cisco 6509 IOS 12.2(18)SXF13.

Something like this:

ip dhcp pool ap-clients

   network 148.66.155.0 255.255.255.0

   default-router 148.66.155.7

   dns-server 148.66.111.23

I would like to block some mac adress which do not follow internal rules.

How can I log each binding ?

Should I use dhcp server database ?

Thanks,

Rosa

Thanks for your answer.

In fact I have a question.

I am needing information such as shown in comand:

#sh ip dhcp binding

IP address       Client-ID/ Lease expiration        Type

Hardware address

148.66.155.71     01d8.3062.6d0d.66       Dec 20 2010 02:58 PM    Automatic

148.66.155.121   0100.13e8.3633.5b       Dec 21 2010 03:29 AM    Automatic

148.66.155.131   c417.feba.4b91            Dec 21 2010 12:18 AM    Automatic

I have never seen output from dhcp server database and I am supposing it outputs only  the most recent bindings not all of then.
