The clock priorities have been configured properly in each NE but the clock view does not show the link status
iew only shows
Go to VIEW menu / Display Settings / Legend and The legend view is comming out.
Click in Filter and thick "link Level"
When an U2000 Client is installed, the Link levels are disabled by default and it doesn't show the Clock Links even if they are working Properly
Once the U2000 Is installed, try to thick all the functions in the legend.
