Router# network-clock switch manual
{interface interface_name slot/card/port |
external slot/card/port | internal T0}
Example:
Router#network-clock switch manual
interface GigabitEthernet 0/0/0 T0
Manually selects a synchronization source, provided the
source is available and is within the range.
Router#network-clock clear switch {t0 |
external <slot/card/port> [10m | 2m]}
Example:
Router#network-clock clear switch t0
Clears the forced switch and manual switch commands.
