![]() Target individual software versions for similar devices. Implement the following steps for software version control:ĭetermine device classifications based on chassis, stability, and new feature requirements. Note: Similar network devices are defined as standard network devices with a common chassis providing a common service. Overall, software version control improves network availability and helps lower reactive support costs. This makes the environment less complex and easier to support. Limited software versions also reduce the risk of unexpected behavior with user interfaces, command or management output, upgrade behavior and feature behavior. This improves the chance for validation and testing on the chosen software versions and greatly limits the amount of software defects and interoperability issues found in the network. ![]() Software version control is the practice of deploying consistent software versions on similar network devices. Naming conventions and Domain Name System/Dynamic Host Configuration Protocol (DNS/DHCP) assignments We recommend the following standards for optimal network consistency: The diagram below shows how you can use the critical success factors followed by performance indicators to implement a successful configuration management plan.Ĭreating standards for network consistency helps reduce network complexity, the amount of unplanned downtime, and exposure to network impacting events. High-Level Process Flow for Configuration Management We'll look at the following steps in detail: create standards, maintain documentation, and validate and audit standards. ![]() This best-practice document provides a process flowchart for implementing a successful configuration management plan. Higher network costs due to unused network components Increased reactive support issues and lower availability Inability to determine user impact from network changes We have seen the following issues resulting from a lack of configuration management: Improved network availability due to a decrease in reactive support costs and improved time to resolve problems. ![]() Lower network costs due to device, circuit, and user tracking tools and processes that identify unused network components. Lower support costs due to a decrease in reactive support issues. By building and maintaining configuration management best-practices, you can expect several benefits such as improved network availability and lower costs. Configuration management is a collection of processes and tools that promote network consistency, track network change, and provide up to date network documentation and visibility. ![]()
