NSNA solution in an active network deployment

You can deploy the NSNA solution on an existing, active Ethernet Routing Switch 5000 Series switch. You must upgrade the switch to a minimum software release of 4.3, and you must understand how the implementation of NSNA on the edge switch impacts the switch functions.

The term network access device is used to refer to the Ethernet Routing Switch 5000 Series edge switch when it is configured for the NSNA environment.
