show network-clock clock-source


Displays the configured network clock source information.

Syntax Description




Usage Guidelines

The E4G-200 and E4G-400 have clock sources beyond SyncE. The clock which drives all of the ports on a switch may be selected from:
  • SyncE (Synchronous Ethernet).

  • PTP – Precision Time Protocol, an optional 1588v2 module.

  • TDM – an optional module which has multiple T1/E1 interfaces for TDM/Ethernet interworking.

  • BITS – Building Integrated Timing Supply. A connector capable of receiving a timing signal provided by other building equipment.


The following is an example for an E4G-400 switch:

E4G-400.1 # show network-clock clock-source
Input Clock Source             :  Sync-E
Input Quality Level            :  QL-SEC (11)
Input Region                   :  E1
Input Clock Status             :  LOCAL CLOCK
Output Bits BNC 1 Clock Source :  8KHz
Output Bits BNC 2 Clock Source :  E1
