VIAVI TestCenter PX3-QSFP-DD-8 / DX3-QSFP-DD-8 appliances - Why does changing the port speed intermittently take up to 20 minutes, and sometimes the port may still be "Unavailable".
VIAVI Engineering is still investigating this issue and plans to have the issue resolved for the 4.96 release.
If the port continues to be "Unavailable" the current workaround is to reboot the port group and restart the STC GUI.
