• Forward Delay – The maximum time (in seconds) this device will wait
before changing states (i.e., discarding to learning to forwarding). This
delay is required because every device must receive information about
topology changes before it starts to forward frames. In addition, each
port needs time to listen for conflicting information that would make
it return to a discarding state; otherwise, temporary data loops might
result.
-Default: 15
- Minimum: The higher of 4 or [(Max. Message Age / 2) + 1]

• Path Cost Method – The path cost is used to determine the best path
between devices. The path cost method is used to determine the range
of values that can be assigned to each interface.
- Long: Specifies 32-bit based values that range from 1-200,000,000.
(This is the default.)
- Short: Specifies 16-bit based values that range from 1-65535.
• Transmission Limit – The maximum transmission rate for BPDUs
is specified by setting the minimum interval between the transmission
of consecutive protocol messages. (Range: 1-10; Default: 3)
