Comware

Hello community! 

I've been trying to get the 4G interface up on the router but nothing seems to work. Let me show you what I have discovered so far. 

So I have my Celluar interface UP and it is attached to the Eth-Channel 1/0:0

Cellular1/0
Current state: UP
Description: Cellular1/0 Interface
Last clearing of counters: Never
Modem status: Present
DM port status: Disabled
Capability:
1 Control channel,, 1 ETH channel
Control channel 0 traffic statistics:
TX: 0 packets, 0 errors
RX: 0 packets, 0 errors
ETH channel 0 traffic statistics:
TX: 0 packets, 0 errors
RX: 0 packets, 0 errors

controller Cellular1/0
eth-channel 0

interface Eth-channel1/0:0
description CONEXION 4G
dialer circular enable
dialer-group 1
dialer timer idle 0
dialer timer autodial 5
dialer number *99#
ip address cellular-alloc
tcp mss 1024
nat outbound

If I check the status of the interfaces, I am seeing this: 

Eth-channel1/0:0
Current state: DOWN
Line protocol state: UP(spoofing)
Description: CONEXION 4G
Bandwidth: 100000kbps
Maximum Transmit Unit: 1500
Internet protocol processing: disabled

It is saying that The physical interface is Down but the line protocol is UP. I have read about this error and it seems to me that the router is not matching correctly the interfaces. 

I have rebooted, reset, re-configured and still, I am not able to bring the physical interface UP. 

May I have some help to solve this issue? 

Cquirozb,

Can you please share the configuration with us?  I am pretty sure you are missing something like the dial string.  Which carrier are you trying to connect to?

I have a couple of these running in the lab without any trouble.  We have AT&T and Verizon SIM cards.

Thanks!

David

Hello David! Thank you very much for your reply!

Here is the configuration that I'm using for the Eth-Channel1/0:0

interface Eth-channel1/0:0

description CONEXION 4G

dialer circular enable

dialer-group 1

dialer timer idle 0

dialer timer autodial 5

dialer number *99#

ip address cellular-alloc

tcp mss 1024

nat outbound

dialer-group 1 rule ip permit

I will paste the configuration edited as well. I left what I believe is "relevant".

Is there something missing ? 

I am trying to connect to Telefónica.

If you need further information please let me know so I can get it ASAP. Thank you very much for the help David!

What's the purpose of tcp mss 1024 command on your configuration? what's the result of display cellular-ethernet all, display interface cellular-ethernet and display dialer commands?

Shouldn't be present a directive:

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

to get to your ISP?

Hello Community! 

The problem was within the equipment. We changed it and the link came up. 

Thank you very much for all your help!

We were able to fix the issue by changing the equipment, but! I have the faulty one in my hands and I really want to know if there is something wrong within the equipment. 

Regarding the static route. That is true, I have to configure that in order to have access to the internet. Nevertheless, I should be able to get an IP address from my SIM Card for the 4G Network even if the route is not there.
