TIMERS
Max. Age Time: This is a user changeable parameter. Should a Bridge fail to receive an identifier packet from its Root Bridge within this time limit, it assumes that the Root Bridge has failed. Therefore, a new Root Bridge will be established for the network.
Hello Time: This is a user changeable parameter. Should a Bridge be assigned as a Root Bridge, the Hello Time setting will be used as the interval to send out identifier packets to notify other Bridges of its existence. The Hello Time must be less than the Max. Age Time, or else a configuration error will occur.
Forward Delay: This is a user changeable parameter. This is the delay time that each port on a Bridge waits in the Listening state before changing its Blocking state to the Forwarding state.
