When I change the status of switch from close to open no changes have been observed in the feeder ID.
I am using Arcfm 10.8 when I make changes in the switch its add or remove feeder ID in all connected layers and features. but not observing the same in UN 

Using arcgi pro 3.6

The subnetwork name field (the UN equivalent of feeder id) isn't automatically updated, much like with feeder manager 2.0 you must run a separate command to populate the field. In this case you must run update subnetwork.

In addition to this, many customers configure their subnetworks to not update the field when in a named version (for performance reasons). You should be able to verify that the features are energized by running a subnetwork trace. The subnetwork name field (feederid) will become populated once the version is posted to SDE.Default and update subnetwork is run on SDE.Default.

Please suggest how to run a separate command to populate the field. 

I run the update, but no changes observe

[RobertKrisher]

The field is updated when you run update subnetwork, but if you're using the standard ArcFM model you will only see that field updated when you run the tool in default.

If you are not seeing this, please open a case with support.
