Here is a link to Cisco documentation concerning DHCP origin and database files:Įssentially, you need a tftp/ftp server that records leases from the DHCP server in a database file (text file) on the Cisco device and reads the origin file (also a text file) in which you create all the manual bindings you need.
Also, 'sh ip arp i 0/24' will show just the MAC address(es) on that port. If you're all Cisco, 'show cdp neighbor' (or 'sh cdp nei') will get you to the next switch. There is a solution to avoid the multiple manual bindings. (Small tip: When you see a large number of MAC addresses showing up on a single port, there's a switch on that port into which those MAC addresses are connected. Our database comes in the following forms: JSON, CSV, XML, Cisco vendorMacs.xml for maximum compatibility and fast integration into existing systems.

I go into the pool I need to reserve the IP in, but I do not have the address command as an option to do it like I have in the past on IOS.
