Enabling STP Protocol (Active)
The active option acts as an On/Off switch for the STP protocol. The

are placed in the forwarding state. If the option is turned “On”, the root
and repeater LAN ports are placed in the listening state.

If you are running a small infrastructure, and there will never be any
loops, leave the STP protocol “Off”. If you are unsure, change the set-
ting to “On” as the overhead involved for bridges is small.
