The only way I know how to acomplish DHCP reservation is to have a dedicated dhcp server outside of the asa running mac reservations<br />
The earlier command would statically allocate mac to ip arp resolution but not static DHCP reservation

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
