Usage Guidelines

Usage Scenario

You can run this command to configure a clock running mode for the

NetEngine 8000 F.

If you configure free, the system clock works in free-running mode. In this mode, the NetEngine 8000 F does not use the clock source selection algorithm to select a clock source.
If you configure hold, the system clock works in hold mode. In this mode, the NetEngine 8000 F uses the locked clock signals.
If you configure normal, the NetEngine 8000 F uses the clock source selection algorithm to select a clock source. If no clock source is available, the system clock automatically works in free-running or hold mode.

Precautions

In VS mode, this command is supported only by the admin VS.

Example
