Configuring the MST Hello Time

You can configure the interval between the generation of configuration messages by the root bridge for all
instances on the device by changing the hello time.

root secondary global configuration commands to modify the hello time.
Before You Begin
Ensure that you are in the correct VDC (or enter the switchto vdc command).
