Problem Cause

NetScaler SD-WAN 10.0 includes a new centralized licensing feature to accomodate large scale deployments. New sites or license changes must generate their license through the MCN. The MCN hands down licenses to client nodes through their RCN using the control data path. If for whatever reason (e.g. when real license expires, connectivity is broken, user removes license, system boots up first time with no license etc) the client is unable to obtain a license from the MCN, it will be issued with a Grace License. This provides a grace period of 45 days.

The Grace License bandwidth will be the license rate selected in site configuration.
