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]
- Maximum: 30

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.
- 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)
