show network-clock clock-source


Displays the configured network clock source information.

Syntax Description




Usage Guidelines

The ExtremeSwitching switches have clock sources in addition to SyncE. The clock that 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 a switch:

# 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
