Hello!
I've got MSR954 JH299A 4G router which won't bring up the eth-channel after it reboots the system regardless of the configuration. This results in NTP and DNS services unable to serve the clients, also the clients can't access the internet as the interface is down. The only way to bring it up is to ping a random site by its IP-address on which the physical interface is brought up and everything works. The issue has been present since I got the device and it has to be a setup related problem as I have the same issue on another MSR954 JH299A if it runs on 4G.
On technical level everything is sound as the SIM is inserted and functional, subscription is set and when the interface brings itself up everything works flawlessly.
The setup is following:
DIALER-GROUP 1 RULE IP PERMIT
APN-PROFILE 0
APN STATIC internet // provider specified only required APN parameter
CONTROLLER CELLULAR 1/0
ETH-CHANNEL 0
MODE LTE
INT ETH-CHANNEL 1/0:0
UNDO SHUT
IP ADDRESS CELLULAR-ALLOC
APN-PROFILE APPLY 0
DIALER CIRCULAR ENABLE
DIALER-GROUP 1
DIALER NUMBER *99#
NAT OUTBOUND
IP ROUTE-STATIC 0.0.0.0 0 ETH-CHANNEL 1/0:0
DNS SOURCE-INTERFACE ETH-CHANNEL 1/0:0
I tried to resolve the issue by creating a job which pings my own server to get it up but the reality is after rebooting the scheduler is clear from previously scheduled jobs, thus making forcing to find a solution for the root of the problem as the router is deployed at customer's premise and I can't access it physically. To make it accessing the internet the need is to log into the router and ping by an IP-address.
After reboot command "disp ip int eth-channel" shows:
Eth-channel1/0:0 current state: DOWN
Line protocol current state: UP(spoofing)
After ping:
Eth-channel1/0:0 current state: UP
Line protocol current state: UP(spoofing)
Also, the eth-channel tends to shut down itself after an idle period on the interface.
Command "disp cellular 1/0" shows:

I can't get the eth-channel interface up by command "undo shutdown" as its status will remain unchanged - Eth-channel1/0:0 current state: DOWN
Firmware is on Comware version 7.1.064, Release 0809P33 but that's is not an issue as the same problem has been present on the firmwares prior that one.
NTP is configured and enabled but that won't change the behavior of the physical interface.
Can someone advice what else configuration has to be applied to get 4G eth-channel up as its unwillingness to get up when the setup is applied is the root of the issue. I've read all the MSR954 configuration manuals and no, I haven't found anything that would help me resolve the issue by myself.
