某局点MSR810-LM路由器4G拨号失败,现场将4G移动卡换到其他设备可以拨号成功,其他设备正常的SIM卡换到这台设备也是依然拨号失败。和现场客户确认了设备配置的APN接入点以及认证都和其他正常设备是一样的。接下来进行分析。
1、搜集配置检查发现没有问题:
#
dialer-group 1 rule ip permit
#
controller Cellular1/0
eth-channel 0
#
interface Eth-channel1/0:0
dialer circular enable
dialer-group 1
dialer timer idle 0
dialer timer autodial 5
dialer number *99# autodial
ip address cellular-alloc
#
ip route-static 0.0.0.0 0 Eth-channel1/0:0
2、搜集4G拨号接口的详细信息分析:
