[ CSCvg26013 / FN64251] - Bug

What needs to be validated

The affected modules as per CSCvg26013 / FN64251 fail to come up after reload.

Why it needs to be validated

Upgrade causes switch reload and hence it is important to verify if the SN is affected by the above FN prior to upgrade. If it is affected, the FC/LC has to replaced prior to upgrade.

Code to be added.
