MAC addresses - EMACS at CO

Question

One of these things is typically combined with the system priority to make a system ID in the Link Aggregation Control Protocol, or LACP. These things are statically or dynamically learned when adding them to a CAM table, and are removed over time in a process called “aging”. The first bit of these things indicates whether they’re universally or locally administered. These things contain an organizationally unique identifier, or OUI, (-5[2])that is assigned to manufacturers by IEEE (“I triple E”). Switches contain (15[1])a (*) table that maps these things to ports, which determines where to forward layer 2 frames. As of iOS 14 and Android 10, these things are always randomized when connecting to a Wi-Fi network to make it harder (10[1])to track devices. For 10 points, name these 48-bit values that are similar to IP addresses, except they identify physical devices on a local network. ■END■ (10[2])
