Release Information
Statement introduced in Junos OS Release 12.2 for ACX Series Routers.
Description
Configure an interface with an upstream clock source to be considered one of the candidate sources for the chassis synchronization by the clock source selection algorithm.
Options
interface-name | — | Consider the specified interface as a candidate source. |
priority number | — | Specify a priority level between 1 and 5. When not specified, gps has higher default priority than bits, and bits has higher default priority than other Gigabit Ethernet, 10-Gigabit Ethernet, T1, or E1 clock sources, which have the lowest default priority. |
quality-level | — | Specify the level of the Ethernet Synchronization Message Channel (ESMC) Ethernet equipment clock (EEC). The quality level specifies the expected accuracy level of the clock and is transmitted across the network through Synchronization Status Messages (SSMs) over the ESMC. |
request force-switch | — | Force a switch to the source provided that the source is enabled and not locked out. Only one configured source may be force-switched. |
request lockout | — | A lockout may be configured for any source. When a lockout is configured for a source, that source will not be considered by the selection process. |
wait-to-restore minutes | — | Specify a time for each port to be up before opening the ESMC—from 0 to 12 minutes. When a port’s signal transitions out of the signal fail state, it must be fault free for the wait-to-restore time before it is again considered by the selection process. |
Required Privilege Level
