• priority—Configures the priority of the network clock source. Values
range from 1 to 6.
• type—Interface type that needs to be configured like Gigabitethernet, POS,
CEM and so on.
• interface name—Configures the network clock source to the selected
interface.
• global—Configures the network clock such that it uses a global
configuration.
• local—Configures the network clock such that it uses a local configuration.
Only one source can be configured at a
Note
time.
Configures the revertive mode on the network clock.
