    疑難排解

    排除數據機故障時，第一步是確定CGR是否可以識別模組。

    驗證CGR是否可以識別3G模組

    安裝並配置3G模組後，CGR有時無法識別該模組。

    1.運行show cellular 3/1 all命令以驗證CGR是否可以識別模組並顯示所有相關資訊。如果輸出中的所有欄位都顯示「未知」，請重新載入模組並等待多達兩分鐘，然後再次進行驗證。

    2.如果所有欄位甚至在重新載入後都顯示「未知」，請關閉/不關閉蜂窩介面並等待最多兩分鐘，然後再次發出show cellular 3/1 all命令。

    附註：如果所有欄位值繼續顯示「未知」，請聯絡思科TAC以更換模組。附加包含上述故障排除的日誌以及「顯示清單」的輸出，以獲取序列號資訊。 

    重新載入3G模組

    使用此命令僅重新載入3G模組。

    ast03-cgr1120-cgosB# reload module 3
reloading module 3 ...

    退回手機網路介面

    使用此命令關閉/不關閉蜂窩介面。 

    ast03-cgr1120-cgosB# conf t
Enter configuration commands, one per line.  End with CNTL/Z.
ast03-cgr1120-cgosB(config)# interface cellular 3/1
ast03-cgr1120-cgosB(config-if)# shut   <<<<<<<<<<<<<<<<<   Wait for 30 sec
ast03-cgr1120-cgosB(config-if)# no shut

    3G模組啟動並正常工作時的輸出示例

    模組工作正常時「show cellular 3/1 all」的輸出。

    ast03-cgr1120-cgosB# sh cellular 3/1 all

    檢查3G模組是否已識別但沒有連線

    檢查蜂窩介面

    發出show ip interface brief命令，並驗證行動介面是否收到IP，狀態是否為UP。如果介面無法獲取IP，請繼續執行trpubleshoot。

    ast03-cgr1120-cgosB# sh ip int b
IP Interface Status for VRF "default"(1)
Interface            IP Address      Interface Status
Cell3/1              192.0.2.1       protocol-up/link-up/admin-up

    檢查訊號強度

    接收訊號強度指示(RSSI)指示3G模組接收的訊號強度。可以使用show cellular 3/1 radio 命令檢查此問題。

    ast03-cgr1120-cgosB# sh cellular 3/1 radio

Current band = WCDMA_V_850
Radio power mode = On
Channel number = 4359
Band selected = Auto
Current RSSI = -92 dBm

    RSSI值：

    1. RSSI至少應大於–90才能獲得可靠的連線。RSSI大於–60表示強大的訊號強度。

    2.如果RSSI小於–100，模組將無法連線到網路。這可能是因為以下原因：

    • 蜂窩介面管理性關閉；no關閉蜂窩介面並檢查RSSI值是否更改。
    • 模組停滯在低功率模式下；shut/no shut the cellular interface and check if the RSSI value changed（關閉/否關閉蜂窩介面並檢查RSSI值是否更改）。等待30秒，然後發出no shut(不關閉)。
    • 天線缺失或未正確連線。
    • 該地區沒有3G服務覆蓋。

    3.如果RSSI大於–60，則需要更多故障排除。啟用調試以進一步診斷問題。

    檢查IP地址連線

    1.使用show ip interface brief和show cellular 3/1 all 命令驗證模組是否發起出站呼叫並收到IP地址。驗證此情況的調試輸出示例：

    2009 Feb  5 22:57:51.479132 dialer: Dialer1 is in READY state

2009 Feb  5 22:57:52 ast03-cgr1120-cgosB %DIALER-5-DIALER_DIAL_OUT: Dialer1 dial out cellular3/1 successfully

2009 Feb  5 22:57:55.995243 cellpm: interface cellular 3/1 IP address 192.0.2.1

    2.如果發出出站呼叫但未收到IP地址，請收集日誌，使用show log檢視斷開原因 |無指令並將其附加到TAC案例。

    3.如果沒有出站呼叫請求，請執行空中初始化(IOTA)以驗證是否可以建立連線（僅適用於CDMA模組）。

    cellular3/1 cdma activate otasp *22899

    (i)如果IOTA連線成功，請檢查硬體或配置問題。

    • show interface cellular 3/1
    • show controllers cellular 3/1
    • show tech

    (ii)如果IOTA連線失敗，請驗證原因日誌，然後發出以下命令：

    • 顯示日誌 |否 

    成功連線時的調試輸出示例：
