排除WxC中MPP电话的调配和注册故障
简介
本文档介绍在通过MAC地址添加设备时，如何排除WxC中的MPP电话的调配和注册问题。
要求
Cisco 建议您了解以下主题：
- 基本网络知识
- MPP电话
使用的组件
本文档中的信息仅基于MPP电话，例如78XX、88XX。
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
在Control Hub中添加设备
步骤1:导航到admin.webex.com并使用管理员凭证。在组织中，导航到设备>添加设备：
“设备”选项卡
第二步：选择要分配给用户的个人使用情况，或选择要分配给工作区的共享使用情况。（在此场景中使用用户。）
添加设备
第三步：搜索并选择要分配给此设备的用户，然后单击Next：
搜索用户
第四步：选择Cisco IP电话并搜索您的设备型号：
选择设备型号
第五步：选择设备后，选择By MAC Address选项并输入设备的MAC地址，然后单击Save：
添加 MAC 地址
第六步：设备进入Control Hub后，您可以在搜索栏中搜索MAC地址时验证添加正确：
设备验证
由于设备仍未调配，状态显示为“不可用”。一旦设备在Control Hub中，下一步就是出厂重置设备。出厂重置后，设备必须向WxC服务器发出请求以获取配置文件。（这是调配过程。） 当设备在屏幕上显示电话号码和/或分机时，设备调配成功。
如果您看到设备未显示正确的配置，则调配设备的过程失败。

调配图
在WxC中调配设备的过程故障排除
如果MPP设备配置有以下内容，则无法通过WxC进行调配：
- DHCP服务器中配置的TFTP服务器
- 如果选项（OPT66、OPT160、OPT159或OPT150）由DHCP服务器配置和提供
要查看电话是否从DHCP服务器获取了TFTP配置，需要PRT日志。
从MPP设备生成PRT日志
通过电话提交PRT日志。接下来的步骤显示如何生成PRT日志。
从设备生成PRT
第1步：在设备上，按Applicationsbutton Settings按
钮。
第2步：转至状态>报告问题。
步骤3.输入问题的日期和时间。
第4步：从列表中选择描述。
第5步：按提交。
提交日志后，请参阅以下步骤下载PRT日志：
步骤1: 登录https://IP_ADDRESS_PHONE/
注意：注意：如果IP地址未知，可从设置>状态>网络状态> IPv4状态获取它
第二步： 导航到信息>调试信息>下载PRT日志(右键单击链接并选择另存为……)
Web GUI
PRT日志
打开日志时，您可以看到如下所示的视图：
注意：由于日志已压缩，因此可以使用类似WinRAR的程序打开日志。
PRT日志视图
要分析调配设备的过程，需要打开名为
logcat的日志。它可以通过
记事本或
记事本++等文本编辑器打开。
可以使用文本编辑器中的“Find”功能来查找电话是否配置了TFTP服务器。使用
DHCP-tftpsvr1或
DHCP-tftpsvr2查找该日志的特定行。如果您查看日志和其他行，可以找到有关DHCP配置的详细信息：

故障排除DNS（调配URL）
如果您所在的网络中的设备存在DNS解析问题，可以使用nslookup检查DNS服务器是否能够解析域。打开命令行界面，然后执行以下步骤：
- nslookup ->输入
- set type=A -> Enter
- activate.cisco.com
如果PC可以解析域，则其可能如下所示：
nslookup activate.cisco
对cisco.sipflash.x可以执行相同的过程来解析域：
nslookup cisco sipflash
如果PC无法解析域，请查看您的DNS服务器。

完成此过程后，设备必须启动并注册到WxC服务。
排除DNS故障（注册URL）
如果您所在的网络中存在与DNS解析有关的设备，可以使用nslookup检查DNS服务器是否能够解析域。打开命令行界面，然后执行以下步骤：
- nslookup ->输入
- set type=SRV -> Enter
- _sips._tcp.da02.hosted-us10.bcld.webex.com
如果PC能够解析域，则其可能如下所示：
nslookup SRV OBP
数据包捕获（注册过程）
您可以获取电话用于注册的IP地址，可在数据包捕获中使用过滤器来查看TLS握手：
PCAP SSE
数据包捕获有助于查看TLS握手是否失败。
