Test and validation
After the risk level of the potential change has been assessed, the appropriate amount of testing
and validation can be applied.
Table 86: Testing and validation recommendations
demonstrates
how testing and validation may be applied to the five-level risk model.
For changes with risk levels 1 through 3, two types of laboratory validation are important:
●
Feature and functionality testing
●
What-if analysis
Feature and functionality testing
Feature and functionality testing requires that you validate all configurations, modules, and
software with laboratory-generated traffic to ensure that the solution can handle the expected
traffic requirements. Create a test plan that validates configuration parameters, software
functionality, and hardware performance. Be sure to test behavior under real-world conditions,
including spanning-tree changes, default gateway changes, routing changes, interface flaps,
and link changes. Also validate the security and network management functions of the new
solution.
Table 86: Testing and validation recommendations
Risk level
Recommendations
1
Requires laboratory validation of the new solution, including
documented testing, validation, and what-if analysis showing the
impact to existing infrastructure; completion of an operations support
document, backout plan, and implementation plan; and adherence to
the change process. Recommend solution pilots and a preliminary
design review prior to testing.
2
Requires laboratory what-if analysis to determine the impact to the
existing environment with regard to capacity and performance; test
and review of all routing changes; backout plan, implementation plan,
and adherence to change process; and design review for major
routing changes or backbone changes.
3
Requires engineering analysis of the new solution, which may require
laboratory validation; implementation plan and adherence to change
process.
4
Requires implementation plan and adherence to change process.
5
Optional adherence to change process.
