  • How To Do A Proof of Concept

    Posted September 20, 2009 - 9:53 pm

    All design changes you make to your network must be tested with a proof of concept plan. It is important to test the current design, configuration and IOS versions in a non-production environment or on the production network with limited disruption. Implementation of newer network modules at a router, for instance, could require that you change the current IOS version that is implemented. Making those changes could affect WAN or campus modules already installed at production routers. That is the real value of doing a proof of concept and certifying that the new equipment and IOS versions integrate with each device as well as the network.
