NMCLI設備不可用

Question

我想在ubuntu core 16.04上配置一個帶有蜂窩接口的新設備。我運行了NMCLI軟件包。在我加入我的連接我檢查了接口

# nmcli dev 
DEVICE TYPE  STATE   CONNECTION   
eth1  ethernet connected  Wired connection 1 
wlan0  wifi  disconnected --     
eth0  ethernet unavailable --     
cdc-wdm0 gsm  unavailable --     
lo  loopback unmanaged  --  

我說我的連接：

nmcli con add type gsm ifname cdc-wdm0 con-name MyConnection apn myapn.com 

最後我試圖把連接通過運行：

nmclil con up MyConnection 
Error: Connection activation failed: No suitable device found for this connection 

而且我已經貼了應用Config的輸出：

# nmcli -p con show MyConnection 

        Connection profile details (MyConnection)

我的問題是如何啓用不可用的設備，爲什麼它不可用？我可以檢查什麼來幫助我解決問題。

任何幫助將是偉大的，因爲我只是開始在Snappy。

Answer 1

好了，所以我設法解決我自己的問題，是我所採取的步驟如下：

1）檢查我的網關調制解調器被Ubuntu核心閱讀：

$ sudo mmcli -L 

Found 1 modems: 
    /org/freedesktop/ModemManager1/Modem/0 [Generic] MBIM [1519:0020] 

2 ）檢查SIM卡正確讀取：

$ sudo mmcli -m 0

這是我意識到，我的SIM尚未在網關發現，我有一個損壞SIM卡，我已經改變了我的SIM卡，並與輸出想出了ABOV即

3）配置新的APN或編輯現有的APN。 （我發現它更容易添加重新連接）

確保您在根（sudo su -）

一）刪除是失敗

#nmcli con delete MyConnection 

b現有連接）創建新的連接

#nmcli con add type gsm ifname cdc-wdm0 con-name MyWorkingConnection apn MyNewApn.com 

4）添加用戶名和密碼，以新的連接

#nmcli con edit MyWorkingConnection 

此時您將處於nmcli>提示符狀態。請輸入幫助以獲取幫助您編輯連接的命令列表。對我來說，我需要添加用戶名和密碼，所以我實現了通過鍵入：

nmcli> set gsm.username data 
nmcli> set gsm.password <passwordgoeshere> 
nmcli> save 
nmcli> quit 

在這一點上我的連接已經建立。我已經找到了命令

#nmcli m 

在另一個會議是檢查接口變化的狀態有用的開放。

希望這可以幫助一些人！
