Video Smart Licensing
The Cisco Smart Licensing feature uses a pooled license model. All FRUs in the chassis and multiple such chassis share the entitlements for Upstream (US), Downstream (DS), WAN, Narrowcast (NC), Broadcast (BC), encrypted licenses (PME, PKY, DVB), and Replicate (RPL) as long as they do not exceed the entitlement count for that pool.
For information on entitlement usage, see the Cisco Smart Licensing.
