I'm looking to find the 'device type' from the MAC Address ina packet capture.
I realise the first 3 bytes indicate the OUI, but once I know it is a CISCO device how can I work out the type of device it is i.e. 6500 catalyst, router etc.
Any pointers in the right direction would be grateful.
A universally administered address is uniquely assigned to a device by its manufacturer; these are sometimes called "burned-in addresses" (BIA). The first three octets (in transmission order) identify the organization that issued the identifier and are known as the Organizationally Unique Identifier (OUI).The following three (MAC-48 and EUI-48) or five (EUI-64) octets are assigned by that organization in nearly any manner they please, subject to the constraint of uniqueness. The IEEE expects the MAC-48 space to be exhausted no sooner than the year 2100; EUI-64s are not expected to run out in the foreseeable future.
