What is h3cMACInfoTrapMsgExt?

This OID holds enhanced binary-encoded MAC information (up to 254 bytes) with a slightly larger cell structure than the standard version, allowing additional metadata. Engineers use it to track MAC address lifecycle events with extended detail about port changes and address types. A typical value might encode MAC learnings on multiple ports with operation type, VLAN, address, and type indicators.
