Using PAN as a DHCP Server - MAC Addresses are Case Sensitive

[RaulTrujillo]

Hi everyone,

I'm having an issue trying to tell our account representative that PAN should treat upper-case or lower-case (or even mixed) MAC addresses as one entry.  I say this because I had an entry in our PAN DHCP Server all in lower-case (entered manually); later, I copied a MAC address into the system was wondering why the device didn't pick up the reserved IP address.  I found out that one was in lower-case and the other in upper-case.  I submitted this as a bug.  However, the tech engineer came back with the following:

Comment: Hello Raul,
RE CASE # 02750803
About this case,
After reviewing your report it looks like the issue was not threating the MAC address as different entries, the issue was actually that since the first entry that you created (MAC lower-case) was still there, is expected it takes the priority.
It would be require as you discover it later to remove any existing entry in case you want to change it for a new IP address.

Note:
Also I found a case were customer reported that he configure a DHCP reservation with MAC address uppercase and they reported connectivity issues on the device with that IP address, the issue in that case was resolve after configuring the reservation with the MAC address all lowercase.

Based on this I suggest the following:
-delete any existing reservation if MAC is the same and you want to assigned a new IP for that device.
-use always lowercase in MAC as best practice.

Please let me know if this answer your questions, if everything is fine please confirm if we can proceed to close the case.
I will be attentive to your reply, thank you!

As you can see, they plan to leave it as is, but I still think it's not right.  I consider this a bug.  Does anyone agree?
