What is myMacNotiHisMacChangedMsg?
This read-only OCTET STRING (1-254 bytes) packs one or more 11-octet MAC change records, each encoding an operation code (learned or removed), a 2-octet VLAN number, a 6-octet MAC address, and a 2-octet interface value. An admin decodes this to reconstruct exactly which MAC address appeared or disappeared, on which VLAN, and on which interface, for a given history entry. For example, an operation byte of 1 followed by a VLAN, MAC, and interface tuple would tell an admin a specific host's MAC address was just learned on that VLAN/port.
