smLooptestStop

Stops loop test. Returns switch LFTs back to normal.

smLooptestInjectPackets

Enter numPkts to send to all switch loops. Default is 1.

smLooptestInjectAtNode

Enter the switch node index to inject loop packets. Default is 0.

smLooptestInjectEachSweep

Sets whether to inject or stop injecting packets each sweep.
