How to create a static Ip address using DHCP on the server


We are getting a new PBX in our company. The PBX provider needs a static IP for the PBX.

I am trying to create the static IP using the reservation option on the DHCP service but I do not what I have to put in the MAC ADDRESS field.

I am not sure if this Mac is for the PBX or what?

Please give  me a hand on this.

Thank you

This would be the MAC address of the PBX, yes. If the PBX has multiple MAC addresses, due to multiple possible connections, you'll need to make sure you use the one that will be connected to your network.
