Sets the time between configuration messages that the bridge generates if it is operating as the root bridge. The current value is shown in the bridgeHelloTime field of the bridge display.

Valid Minimum Abbreviation

Important Considerations

■If the probability of losing configuration messages is high, shorten the time to make the protocol more robust.

■If the probability of losing configuration messages is low, lengthen the time to lower the overhead of the algorithm.

■The recommended Hello time is 2 seconds.

■Although the possible range for stpHelloTime is 1 – 10, the available range is constrained by the following inequality:

stpMaxAge >= 2 x (stpHelloTime + 1 second)
