簡介
本文檔介紹當通過MAC地址新增裝置時,如何排除WxC中的MPP電話的調配和註冊問題。
需求
思科建議您瞭解以下主題:
採用元件
本文檔中的資訊僅基於MPP電話,例如78XX、88XX。
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除(預設)的組態來啟動。如果您的網路運作中,請確保您瞭解任何指令可能造成的影響。
在控制中心新增裝置
步驟1.導航到admin.webex.com並使用管理員憑據。在組織中,導航到Devices > Add device:
Devices頁籤
步驟2.選擇要分配給使用者的個人使用,或選擇要分配給工作區的共用使用。(在此案例中使用了使用者。)
新增裝置
步驟3.搜尋並選擇要分配給此裝置的使用者,然後按一下下一步:
搜尋使用者
步驟4.選擇Cisco IP Phone並搜尋您的裝置型號:
選擇裝置型號
步驟5.選擇裝置後,選擇By MAC Address選項並輸入裝置的MAC地址,然後點選Save:
新增MAC地址
步驟6.裝置進入Control Hub後,可以在搜尋欄中搜尋MAC地址時驗證是否正確新增了該裝置:
裝置驗證
狀態顯示為「不可用」,因為裝置尚未調配。裝置進入控制中心後,下一步是出廠重置裝置。出廠重置後,裝置必須向WxC伺服器發出請求以獲取配置檔案。(這是調配過程。) 當裝置在螢幕上顯示電話號碼和/或分機時,裝置已成功調配。
如果發現裝置未顯示正確的配置,則設定裝置的過程失敗。
在WxC中調配裝置的流程概述
調配圖
在WxC中調配裝置的過程故障排除
如果配置了WxC,則MPP裝置無法通過WxC進行調配:
- 在DHCP伺服器中配置的TFTP伺服器
- 如果選項(OPT66、OPT160、OPT159或OPT150)由DHCP伺服器配置和提供
要檢視電話是否從DHCP伺服器獲取了TFTP配置,需要PRT日誌。
從MPP裝置生成PRT日誌
從電話的PRT日誌中提交。後續步驟顯示如何生成PRT日誌。
從裝置生成PRT
步驟1.在裝置上,按Applicationsbutton
「設定」按鈕 .
步驟2.前往Status > Report Problem。
步驟3.輸入問題的日期和時間。
步驟4.從清單中選擇描述。
步驟5.按提交。
提交日誌後,請參閱以下步驟下載PRT日誌:
步驟1.登入https://IP_ADDRESS_PHONE/
附註:附註:如果IP地址未知,可以從設定>狀態>網路狀態> IPv4狀態
步驟2.導覽至Info > Debug Info > Download the PRT log(按一下右鍵該連結並選擇Save As...)
Web GUI
PRT日誌
開啟日誌時,您可以看到如下所示的檢視:
附註:您可以用WinRAR等程式開啟日誌,因為日誌已壓縮。
PRT日誌檢視為了分析設定裝置的過程,需要開啟名為logcat的日誌。它可以使用記事本或記事本++之類的文本編輯器開啟。
可以使用文本編輯器中的「查詢」功能來查詢電話是否配置了TFTP伺服器。使用DHCP-tftpsvr1或DHCP-tftpsvr2查詢該日誌的特定行。如果您檢視日誌和其他行,可以找到有關DHCP配置的詳細資訊:

從DHCP伺服器中刪除任何TFTP配置和任何OPT配置後,您必須出廠重置裝置,以便開始使用WxC重新配置裝置的過程。

疑難排解DNS(布建URL)
如果您所在的網路中裝置存在DNS解析問題,可以使用nslookup檢查DNS伺服器是否能夠解析該域。開啟命令列介面並執行以下步驟:
- nslookup ->輸入
- set type=A -> Enter
- activate.cisco.com
如果PC可以解析域,則它可能如下所示:
nslookup activate.cisco
cisco.sipflash.x解析域時可以執行相同的過程:
nslookup cisco sipflash
如果PC無法解析域,請檢視您的DNS伺服器。

完成此過程後,裝置必須啟動並註冊到WxC服務。
疑難排解DNS(註冊URL)
如果您所在的網路中裝置存在DNS解析問題,可以使用nslookup檢查DNS伺服器是否能夠解析域。開啟命令列介面並執行以下步驟:
- nslookup ->輸入
- set type=SRV -> Enter
- _sips._tcp.da02.hosted-us10.bcld.webex.com
如果PC能夠解析域,則它可能如下所示:
nslookup SRV OBP
封包擷取(註冊程式)
您可以採用電話註冊的IP地址,資料包捕獲中可以使用過濾器來檢視TLS握手:
PCAP SSE
資料包捕獲可幫助檢視TLS握手是否失敗。
