In general, for network switches supporting MAC notification traps, it's advisable to configure these
traps on all ports except uplink ports. Uplink ports are used for connecting to other switches or
network infrastructure devices and typically don't need MAC notification traps, which are more
relevant for end-device connectivity monitoring.
The study guide specifies that MAC notification traps should not be configured on interfaces that are
uplinks. They are the preferred method for learning and updating Layer 2 information and should be
used whenever available, but not on uplink interfaces.
