Displaying the timer synchronization mode and ETR ports (ETR)

Use the DISPLAY ETR command to display the current timer synchronization mode and the status of the ETR ports as seen by MVS™.

The DISPLAY ETR command issues the following information when the sysplex is running in STP mode:
  • Timing mode.
  • CTN ID.
  • Time.
  • Node that is the source of the time, if applicable.
  • Redundant available timing links, if applicable.
  • Stratum level of the server.
  • Start of changeETS (external time source) information including ETS ID, ETS timing precision, and the PTP Grandmaster ID, if the ETS is using PTP.End of change

See message IEA386I for additional details.

The complete syntax for the DISPLAY ETR command is:

D ETR 
 
D ETR[,DATA][,L={a|name|name-a}]
ETR
Displays the current ETR (external time reference) synchronization and the status of the ETR ports.
DATA
Displays the status, in detail, of each ETR port, giving the ETR network ID, ETR port number, and the ETR ID.
L=a, name, or name-a
Specifies the display area (a), console name (name), or both (name-a) where the display is to appear.

If you omit this operand, the display is presented in the first available display area or the message area of the console through which you enter the command.

Example

To display the current timer synchronization mode status and the ETR ports, enter: 
D ETR
The status is shown in this display: 
IEA282I
hh.mm.ss ETR STATUS SYNCHRONIZATION MODE=mode  CPC SIDE=id

CPC PORT 0       CPC PORT 1
    op              op
    enb             enb
where the fields in the message are:
hh.mm.ss
is the current time in hours(hh), minutes(mm), seconds(ss).
MODE=mode
is the current synchronization mode, ETR, or LOCAL.
CPC SIDE=id
is the current CPC side ID, 0 or 1.
op
is the status of the port, operational or nonoperational.
enb
is the status of the port, enabled, or disabled.
