  1. question, on the last sentence you said the default action is exceeding traffic will be dropped. but you can also use to shutdown the interface or send a trap.

    if you configure to send a trap, the exceeding traffic will not be dropped? just only to inform you that it exceeds?

    because on the selection of action, its only “Shutdown” and “Trap”. theres no “Drop the exceeding traffic”.

    or it works this way that, it will drop the exceeding traffic, you just need to choose the 2nd option on what to do with it? is it you’ll shutdown the interface or send a trap?

  2. Hi John,

    In both cases, the exceeding traffic will be dropped. The only difference is the “extra” action that we perform. Do you want to shut the interface or only send a SNMP trap? That’s it.

  3. Hi Rene,
    Great Article :slight_smile: What is the meaning of the sentence “default action will drop exceeding traffic”. Exceeding traffic means exceeding Broadcast/Multicast/Unknown Unicast traffic will be drop ?? and regular traffic will not, right ?? Thanks

  4. Can you explain exactly what the Unicast element is? What makes a unicast “unknown”? :slight_smile:

  5. Hello Chris

    Unknown unicast traffic is essentially unicast traffic for which a switch does not have the destination MAC address already in its CAM table. Such traffic will require flooding from all of its ports thus adding to the severity of a potential broadcast storm.

    I hope this has been helpful!
