Comment 0 for bug 1755587

This is reproduced by opening up the subnet page and clicking on "Edit" and changing the fabric to point to another fabric. The result is that the value reverts back to the original setting and doesn't get saved.

Expected result:
To have the new fabric id retained after the settings are saved.

Please let me know if you need more detail. Thanks.
