Fixed ip address by DHCP

Unanswered Question

Hello all,

Is the first time I make a question here. Sorry if already was been answered but I've not found it out.

There is anyway to assign a fixed ip address using MAC-Address by DHCP server in a Cisco ASA5510? Now we have a isc-dhcp server running on a Freebsd server, but I want to change it and use the firewall instead but I would like to assign some fixed ip address based on MAC-Address for administration purposes. I don't want to use static ip address because is very annoying change the laptops from static to dhcp client every day.

Hello Oscar,

I have briefly skimmed over the Configuration Guide and Command References to ASA Operating System v8.2 but I was not able to find any indication of the possibility to assign constant IPs to predefined MAC addresses. I am afraid that this will not be possible. Somebody having better information please correct me!

I think that it should be stressed that the DHCP Server functionality implemented in Cisco products is quite limited. I have a feeling that I've seen a statement somewhere written by Cisco itself that for more complex requirements, customers should use external DHCP servers that are better equipped with various functions. The ISC DHCP you're using now is one of the best DHCP servers out there.

Best regards,
