bounce
Brings the active links down and back up if a new value is set.
Sample Output:
-> ismIslSetSpeed 2
L01S3Ba link speed is DDR

This command will set the MTU capability for both internal and
external switching. If the vlCap option is not specified, the command
defaults to the maximumVL(s) for the selected mtuCap. Calling this
function without an mtuCap designator displays the current value for
each port.
Calling this function with the [-bounce] option disruptively brings
active links down and back up so the links use the new setting
immediately. Otherwise the new setting will be used the next time
links retrain.
