I really like Aruba Instant. It's a great solution for branch offices, many retail locations, and if you are a Wi-Fi guy, maybe even your home. A Virtual Controller gives you all the basics and even quite a few advanced features without having to run a traditional hardware controller. That's all fine and dandy until you decide to debug something. There's a lot of detail not obviously exposed in the GUI, but it's there and you can find a lot about what's actually happening in an Instant deployment using the support features and might even learn a bit of CLI goodness while you are at it.
前几天，我真的很想知道手臂状态。我正在解决一个连接问题，并想看看频道是否在变化。找到哪个频道，您目前正在使用的频道很容易，但是如果您想知道发生了什么变化以及为什么，则需要深入研究支持菜单。
如果愿意，您可以运行技术支持转储，您可能以前做过。这是超过8000行的数据。很难找到您想要的东西，甚至还不包括所有内容！您可以选择命令选择更具针对性，并为自己提供更容易使用的数据。您甚至可以在此处搜索术语，它将限制与您的术语匹配的选项，从而更容易找到您真正想要的命令。让我们搜索“ ARM”：
这是一个更合理的选择列表。“ AP ARM历史记录”听起来像是一个有用的命令。让我们看看最近发生了什么变化。

注意说“命令”的顶线。现在，我们知道要在CLI中找到这些数据，我们可以运行“显示AP ARM历史记录”。如果您感兴趣的话，这是学习CLI的好方法。顺便说一句，不要敲CLI。知道如何使用CLI在您必须从远程进行故障排除时特别有用。它比GUI快得多！
This looks like some pretty approachable data. Let's talk about the data we have here:
- We have both radios listed.
- We see 2.4GHz has been on channel 6 for over a month.
- We see that the 5GHz radio has changed channels a couple times, when those changes happened, and that one of them was due to too much RF noise.
- 我们看到两个收音机都改变了功率水平几次。
假设您有一份麻烦报告，该报告抱怨所有客户设备在1月13日晚上失去联系Th. We have a log line that could explain that:
变更时间旧频道新频道旧电源新电源原因结果---------------------------------------------------------------------------------------------------- 2017-01-13 20:15:28 36+ 116+ 24 24 2配置
1月13日晚上8:15Th，由于噪声，AP从通道36切换到通道116。功率水平保持不变。现在，我们有一个合理的解释，说明为什么这一事件在13Thoccurred. Problem explained and probably resolved by ARM moving away from the interference. If you stick the the GUI, you won't be finding out what happened.
该虚拟控制器中不仅仅是明显的GUI组件或您在Aruba Central中看到的内容。进入控制器，稍微戳一下。看看您可以找到什么。挖掘该支持菜单。您可以找到并了解很多有关您的无线系统从这些命令中工作的工作，甚至可能发现您不知道存在的问题。在影响您的用户之前，积极解决问题始终是胜利！
