BPDU Send Interval (Hello Time)
Set in the range from 1 to 10 (seconds). This determines the
interval within which a bridge that is the root bridge sends a packet
notifying its existence. This parameter may not exceed the Max
Age Time.

notifying its existence. This parameter may not exceed the Max
Age Time.
Forward Delay Time
Set in the range 4 to 30 (seconds). When the ports of a bridge
change from blocking to forwarding status, this determines the time
in which they will remain in listening status.
