•Forward Delay — The maximum time (in seconds) the switch
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.
(This is the default.)
•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)
