MSR830 4G拔号失败

#默认会在设备里面多出一个Eth-channel接口，如下：

controller Cellular1/0

eth-channel 0

# 配置拨号访问组1以及对应的拨号访问控制条件。

dialer-group 1 rule ip permit

#配置4G拨号接口：

interface Eth-channel/0:0

dialer circular enable

dialer-group 1

dialer timer idle 0

    dialer timer autodial 60

dialer number *99# autodial   //如果是电信的拨号串为#777，联通和移动都是*99#

    ip address cellular-alloc

    nat outbound 

#配置默认路由，指向4G出接口：

ip route-static 0.0.0.0 0 Eth-channel1/0:0

#配置成功后，把modem模式设置为lte，并重启下modem：

controller Cellular 1/0

  mode lte 

  modem reboot
