• Create cross-connections:
  curl --cookie PHPSESSID=ue5gks2db6optrkputhhov6ae1 -X POST --header "Content-Type: application/json" --header "Accept: application/json" -d "{\"in\": \"1.1.1\",\"out\": \"6.1.1\",\"dir\": \"bi\",\"band\": \"O\"}" --user admin:pxc*** "http://osw-daq-calients320.pcdsn/rest/crossconnects/?id=add"
• Activate cross-connections:
  curl --cookie PHPSESSID=ue5gks2db6optrkputhhov6ae1 -X POST --header "Content-Type: application/json" --header "Accept: application/json" --user admin:pxc*** "http://osw-daq-calients320.pcdsn/rest/crossconnects/?id=activate&conn=1.1.1-6.1.1&group=SYSTEM&name=1.1.1-6.1.1"
  • This doesn't seem to work: Reports '411 - Length Required'
    Use the web GUI for now
• List cross-connections (easier to read in the web GUI):
  curl --cookie PHPSESSID=ue5gks2db6optrkputhhov6ae1 -X GET --user admin:pxc*** 'http://osw-daq-calients320.pcdsn/rest/crossconnects/?id=list'
• Save cross-connections to a file:
  • Go to http://osw-daq-calients320.pcdsn/
  • 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

BOS Connection CLI

Courtesy of Ric Claus.  NOTE the dashes in the "delete" since you are deleting a connection name.  In the "add" the two ports are joined together with a dash to create the connection name, so order of the ports matters.

bos delete --deactivate 1.1.7-5.1.2
bos delete --deactivate 1.3.6-5.4.8
bos add --activate 1.3.6 5.1.2
bos add --activate 1.1.7 5.4.8

Link qualification

Looking at the eye diagram or bathtub curves gives really good image of the high speed links quality on the Rx side. The pyxpm_eyediagram.py tool provides a way to generate these plots for the SFPs while the XPM is receiving real data.
