Discovery jobs to read ARP Cache on Switches

We have an SNMP read only community string on our network switches.  We want to run UD jobs to connect to the switches via SNMP, read the ARP cache and discover any computers in our environment that don't have agents on them.  I'm told that DDMI did this and ran the MAC address against a master list of MAC address assignments by vendor to identify what the device likely is.  Can anyone suggest which discovery jobs could accomplish this in UD?

Re: Discovery jobs to read ARP Cache on Switches

If you are trying to hone in on devices on the network using the switches I believe you can use the Host Networking by SNMP job. Alternatively, if you are just trying to see what else is on the network you could use the Host Fingerprint using nmap job, if you tune the port scan it's actually a pretty effective discovery.
