It worked for me! Thanks a lot. I am using 5506-x.

It seems one can use the command arp to configure a static address to a device … arp [interface] [ip address] [mac address]

Cisco came up 2006 with version 7 for the ASA. 14 years later they thought they had enough people to let them do some nice-to-have features like DHCP reservation. 9.13 should do it. But we know, they wanted to bring back switching functions from the 5505 to 5506, what they never managed (Besides a lot of other things…). So I doubt that DHCP reservation will work on the asa very well. If at all… somehow.

There is an alias option to the arp command that prevents the entry from expiring, would that solve the issue, I have not bothered to test it, but I read from the remarks that an issue would be that the reservation will expire, add alias at the end and it will not?

It worked for the author because he disconnected the device and reconnected it within the window off the original DHCP lease so the device got the same IP. If the lease timed out before he reconnected there is a good change the IP would have already been given out to another device or a lower IP would have been available in the pool and given out instead.

It never worked. DHCP does not reference the ARP table.

When I wrote the article 3 years ago it worked as I have documented. I understand from some of the comments that it doesn’t work any more. I don’t know why, maybe cisco have changed something.
