What is ctAliasMacAddressVlanID?
This is the VLAN ID recorded in the header of the frame associated with this MAC-address-keyed alias entry, or fixed at 1 on agents without VLAN support. It lets an admin looking up a host by MAC address also learn which VLAN that host was communicating on. For example, when investigating a specific MAC address flagged by a security tool, the admin can check ctAliasMacAddressVlanID to confirm which VLAN segment that traffic came from.
