Monitoring System Timing Settings
Purpose
Display the timing settings and the operational status of the system timing. If a timing source fails, the system uses the next time source in the hierarchy, and a message appears in the system log at the warning level. If auto-upgrade is enabled, the system upgrades to a higher-priority timing source when one becomes available, and a message appears in the system log at the notice level.
Action
To display the timing settings and the operational status of the system timing:
host1#show timing
timing: tertiary (failover from primary) primary: external SC E1 (A) (ERROR) secondary: ds3 3/0 (ERROR) tertiary: internal SC oscillator (ok) auto-upgrade enabled
Meaning
Table 39 lists the show timing command output fields.
