Command History
Usage Guidelines
The input network clock reference selection can be forced or automatically selected using an algorithm
based on the highest priority valid input clock.
•
In revertive mode, the forced clock automatically becomes the selected reference.
• In non-revertive mode, the forced clock is selected only with the existing reference is invalidated or
made unavailable.
You use the network-clock-select mode { nonrevert | revert } global configuration command to set the
mode.
You can use set network-clocks next-select command to scroll through the set of available clocks.
After you force the network clock selection by entering the set network-clocks force-select or set
network-clocks next-select command, the system remains locked to the selected clock even if it
becomes invalid.
You can verify your settings by entering the show network-clock privileged EXEC command.
Examples
This example shows how to set clock selection to automatic:
Switch# set network-clocks automatic
automatic Selects automatic clock selection. The clock with the highest priority
is always automatically selected as the input clock.
force-select Forces the system to reselect a valid network clock with the highest
priority.
next-select Forces the system to select the valid clock with the next highest
priority.
