DHCP : Bind MAC with wildcard to a specific IP-Range ?

Hello ,

Using a Cisco 1800 series router (1802) with IOS 15.1(4)M2.

I am quite sure the following should somehow be possible in IOS, but I can't figure out how to do it ... :

I have the situation that I need to bind specific devices by DHCP to the same IP range.

These devices (medical equipment, used in hospital) are all from the same vendor.

So the first three octets in the MAC address (Organizationally Unique Identifier , OUI) are the

same for each device. The next three are always 'unknown'.

I know how to bind a fully known MAC address to a host ip or ip range ,

but is it somehow possible to do this by the OUI ??

Like using some wildcard option.

Best regards

Re: DHCP : Bind MAC with wildcard to a specific IP-Range ?

I don't think this is possible. You can bind a single address to a single mac address, but depending on how many devices you have it could be a pain to try to manage. The better option may be to create a vlan for these devices only and then assign your addresses based on that.

The other option that you may have is to create an origin file and map all of your static addresses in there:
