  curl --cookie PHPSESSID=ue5gks2db6optrkputhhov6ae1 -X GET --user admin:pxc*** 'http://osw-daq-calients320.pcdsn/rest/crossconnects/?id=list'
• Save cross-connections to a file:

  • Navigate to Ports→Summary
  • Click on 'Export CSV' in the upper left of the Port Summary table
  • Check in the resulting file as lcls2/psdaq/psdaq/cnf/BOS-PortSummary.csv
