jnxLicenseFeatureDescr provides a descriptive text string for a licensed feature entry, meant to complement the shorter jnxLicenseFeatureName field in the same table row; the source MIB's DESCRIPTION text for this object is a copy-paste of the name field's text, so this reading follows from the object's own name and DisplayString syntax rather than that duplicated wording. An admin would use it to get a fuller explanation of what a listed feature actually does when the short name alone isn't clear. For example, where jnxLicenseFeatureName might show a terse code, jnxLicenseFeatureDescr would ideally spell out in plain language what capability that license unlocks.
