Could you add a oui lookup table or allow the user to download the IEE oui database and upload it to the server this way when macaddresses are discovered or when your looking for a particular mac address it will also show you the Vendor associated with the MAC ... As well as being able to generate a report based on vendor... example if i want to find out how many Axis encoders I have in the system i could look that up based on the current snmp info that was gathered previously ......
Thanks,
P.S This is by far the best NMS I have found compared to the previous if have tried PandorasFMS, Zabbix , libreNMS ,and Nagios Thanks for your hard work
