Low , High or Normal. If the network is congested, the Switch handles packets with a higher priority before those
with lower priority.

keep intruders off your network since any packet coming from an unknown source will be dropped by the Switch,
that is, not added to your MAC Address Forwarding Table. Select Enabled or Disabled.

Forwarding-Trap and the Broadcast Storm Falling Action Threshold that will trigger a Broadcast
Storm Falling Action.
