Reimagine the way you validate network changes with a combined network and end-user perspective via Aruba Central and Aruba User Experience Insight (UXI)
企业在数字转型举措上花了一笔财富。为了更好地支持这些项目，许多IT领导者也在现代化网络基础设施，以改善新的数字应用和服务的交付和性能。
Unfortunately, businesses often struggle to quantify the outcomes of these efforts. Even worse, at times they need to roll back newly implemented network changes – such as device firmware upgrades or even entirely new installs – because overall performance or health suffers, instead of becoming more efficient.
在阿鲁巴岛,我们看到它团队c的情况onfidently rolled out shinning network infrastructure to support an esport event or football tournament, just to realize that it was not working for end users because of sub-optimal positioning of wireless access points (APs).
IT团队需要快速，可靠的方式来识别此过程的早期此类问题，采取纠正措施，或者如果数据比较显示网络输出中的退化，则持有供应商和服务提供商负责。这就是阿鲁巴中心和阿鲁巴·乌西的结合进入图片的地方。
This five-blog series,“网络外和内外”说明了Aruba Uxi和Aruba Central如何通过提供多个可观察性的观点来帮助全球各地的TEMS，以主动微调，安全，故障排除，修复和优化网络。
在第二部分中，我们探讨了我们最大的零售客户之一的现实生活场景。Read on to see how they leveraged the Aruba Central + Aruba UXI solution to validate the impact of network changes from an end user’s perspective, using AI-powered insights that make the network more efficient while giving IT operators confidence to execute or rollback network changes in real time.
（第一个系列showcased how Aruba Central and Aruba UXI simplifies life for IT teams by alerting them when a SaaS application drops and provides them with actionable insights to rapidly fix the issues。Do read it if you haven’t already.)
Fixing newly implemented network upgrade in a post-COVID world
世界上最大的零售商之一正准备在冗长的Covid-19锁定后恢复操作。IT组织正在升级网络基础架构，以支持客户的零触摸购物体验。但是，它收到了关于零件Wi-Fi问题的员工和客户的重复投诉，并且客户交易在多家商店的移动点销售点（POS）系统上反复失败。
幸运的是，零售商的IT组织部署了Aruba Uxi和Aruba Central，以优化其新的网络庄园。一旦问题开始浮出水面，它就会迅速收到警报，并在快速故障排除并解决问题。
1）IT管理员单击Aruba UXI仪表板，并发现频道利用率和重试率相当高，以及由于AP发射功率而发生的低比特率展示问题。
2）同时，Aruba Central内的AI Insights功能分析了网络性能，并确认由于以下原因，问题在网络结束时：
- Disabled radar channels
- Lower beacon rate with more SSIDs
- Sub-optimal transmit power
The same AI Insight also provides the following recommendations to fix the issues:
- Enable higher radar channels
- Disable lower beacon rates and increase basic rates to 12 Mbps
- 将传输功率变为推荐值
Better yet, action cards within the AI Insight show which groups of APs and sites are most impacted by these issues, helping the IT admins prioritize and fix events across its chain of retail stores based on business and network impact.
3）Using the AI Search feature in Aruba Central, the admin quickly surfaces the right help documentation and pinpoints where within the user interface they can quickly make the proper configuration changes.
4）Aruba UXI then helps validate the impact of these changes on end-user experience. UXI sensors are deployed at strategic locations throughout the store, which have been monitoring the network through this entire process. The IT admin opens Aruba UXI dashboard and witnesses the impressive results:
- 渠道利用率的50％提高
- RX Bitrate的24％改善
- 帧重试的88％提高
5)在Aruba Central的Aiops Suite中使用公司和同伴基线，IT管理员还能够确定几十个其他商店，这些商店将从相同的配置变化中受益。在只需几个鼠标点击中，更改将在所有适当的站点和设备上推出，即时产生相同的网络性能和用户体验改进。
The best part of the whole exercise was all the execution and troubleshooting were done remotely! No truck rolls, no waiting, and no extra costs!
Aruba Central以及Aruba Uxi提供了一个极其强大的解决方案来测试和验证网络变化，降低了网络和应用程序性能中的任何故障的风险，可能源于次优配置或操作员错误。
