What is hh3cMACInfoTrapMsg?

This object carries the actual MAC address change data reported by a trap, packed as one or more fixed-format 12-octet cells each describing an operation type, VLAN, MAC address, MAC type, and interface index. An NMS decodes each cell to learn specifics like whether a MAC was learned or removed, on which VLAN and interface, and what kind of MAC entry it is (dynamic, static, 802.1x, etc.), giving detailed forensic detail beyond a simple counter. For example, a cell with operationType 1 (learnt), a given VLAN and MAC, MACtype 6 (802.1x), and an ifIndex value tells the admin exactly which port authenticated a new MAC address via 802.1x.
