Verifying the Clock Source Attribute Configuration

Verifying the Clock Source Attribute Configuration


  • Run the display clock { bits0 | bits1 } [ slave ] command to view BITS configurations, including the type of the BITS clock, bit used to transmit the SDH synchronization status code (S1 byte), content of the S1 byte that is set forcibly, and whether the ID of the clock source is prohibited from being sent.
  • Run the display clock source command to view information about clock sources, including the validity of clock signals, SSM quality level, and ID of each clock source.
  • Run the display clock state interface interface-type interface-number command to view the clock status on an interface. You can use this command to query all the clock configurations on an interface.
  • Run the display clock freq-deviation-detect-range command to view the range of frequency offset check.
  • Run the display clock freq-deviation-detect-result command to view the frequency offset check result of a clock source.
  • Run the display clock source-lost holdoff-time command to view the holdoff time for the system to consider a clock source lost.
  • Run the display clock wtr command to view the WTR time of each clock source.
  • Run the display clock mode [ slave ] command to check whether the SSM quality level is used in clock source selection, whether the result of frequency offset check is used in clock source selection, retrieve mode, holding mode, running status, and clock source selection status of each clock source.
  • Run the display clock { left-frame | right-frame } command to check the priorities of the clock signals transmitted from the left-frame interfaces and right-frame interfaces to the clock source on the MPU.
  • Run the display clock lockout command to check whether the clock source is locked.
  • Run the display clock priority command to view the priorities of clock sources.
  • Run the display clock map unk command to check the SSM quality level mapping the unknown level.
  • Run the display clock selection [ slave ] command to check information about clock source selection of the external clock source.
  • Run the display clock ssm-config command to view the SSM quality levels of clock sources.
