Syntax
priority number;
Hierarchy Level
[edit chassis synchronization source interfaces (external-a | external-b | interface interface-name)] [edit chassis synchronization source interfaces (external | interface interface-name)] [edit chassis synchronization source interfaces (external-0/0 | external-1/0 | interface interface-name)]
Description
Configure the priority of a clock source in relationship to other clock sources to define a network synchronization flow and to help prevent timing loops.
When the priority is not specified, the external-a interface has higher default priority than the external-b interface, and the external-b interface has higher default priority than other Gigabit Ethernet or 10-Gigabit Ethernet clock sources, which have the lowest default priority. Any priority you configure is higher than any default priority.
