USB Parameters - Huawei E3276; RAP-155; ArubaOS 6.4.0.3

Hello,


We have the following hardware:

  1. RAP-155
  2. 4G Huawei E3276 USB modem
  3. Aruba7210 Controller with ArubaOS 6.4.03.

Our ISP parameters are :

  1. APN:  internet.se
  2. Access Number: *99#

We have not been able to get the 4G connection working and would therefor be very grateful for any inputs as to what the appropriate USB parameters would be for the above combination.

 

Thank you in advance.

 

Kind Regards

Peter

Thanks for the response kdisc98.  

I have now tried the settings you recommended, but could not get the 4G connection up.

 

I also tried with Dial Strings: ATD*99# and ATDT*99# since our ISP's Access Number is  *99#

 

Any more ideas on what I could try or troubleshoot?

Many thanks in advance!

You may try setting additional modem parameters to:

 

Device Type: huawei-cdc

Device Identifier: 0x12d11506

 

Also, remove PIN from your SIM-card; if you have it working without PIN, you may try to put CPIN=<PIN> in your dialer string:

AT+CPIN=27822;+CGDCONT=1,"IP","internet.se"

I have seen issues with the E3272s where PIN was not supported.

Re: USB Parameters - Huawei E3276; RAP-155; ArubaOS 6.4.0.3

Thanks for your response hrobers,

 

I have tried the suggested settings, with and without the PIN, but have not succeeded in getting up the connection.

I would be grateful for further setting suggestions to try out.

I wonder if there is any way of debugging to try and find out what is going wrong during the connection sequence?

 

 

Best regards

Peter

Peter,

 

Please work with your partner, open a TAC case, or work with your local Aruba SE to get help on this.

 

Few things if you want to find out youself:

 

Convert the RAP to a controller RAP before checking the USB 4G connection. Converting the RAP over USB 4G requires configuration on Instant first, and then also on your controller. 

 

The boot process of your AP should show the dongle present, the modeswitch (if applicable), and the USB modem detected as a modem. To get access to the RAP-155 console, you will need a special console cable:

AP-CBL-SERAP serial adapter cable (proprietary to DB9 female)

If you have another AP, like AP-225, AP-115, RAP-109, there is a RJ45 serial console port on the AP, as well there is an USB port for the dongle.

 

Fully un-powering the AP after configuration has been needed for me few times to get the dongle working. That has to do with the mode switching, and rebooting was not enough in those cases, unplug and replug the AP after a config change.

 

This E3276 requires AOS 6.4 or Instant 4.1 as a minimum. Please also doublecheck your versions.

 

Again, work with your partner, TAC, Aruba SE (in that order) to get you going.

 

Herman

Re: USB Parameters - Huawei E3276; RAP-155; ArubaOS 6.4.0.3

Hi Peter,

 

To configure Huawei E3276 you only need to do this. You should not need to configure dialstrings etc.

 

conf t
provision ap
read-bootinfo al-name <AP-NAME>
usb-type huawei-cdc
usb-dev 0x12d11506
cellular-network-preference auto
link-priority-cellular 8
link-priority-ethernet 1
reprovision ap-name <AP-NAME>
 
I have this up and running with 6.4.0.3 with both Telia and Telnor modems.
You could adjust the values for link-priority if needed. Please let me know if you run into any more issues.

Hi Jonas!

Thanks for your response.

Sorry for the delay in replying, just back from vacation.

I have tried the configurations you sent, but to no avail.

 

We have TDC as our carrier, but I do not think this ought to be the problem.

I have however noted that there are many flavours of Huawei E3276 modems, and on checking closer, the recommended type of modem for this purpose is the Huawei E3276-150 modem.

 

I wonder if this is the specific E3276 modem you are using, (before I order it and make a last effort).

Re: USB Parameters - Huawei E3276; RAP-155; ArubaOS 6.4.0.3

Hi Peter, 

 

I have noticed that with some of the ISPs we need to add the APN information as well i.e. I have tested with Tele2 and DGC and got them up and running if i added this line and change to correct APN adress in it.

 

I have used the Huawei E3276-150 for this so it should work.

 

usb-init        AT+CGDCONT=1,'IP','sp.apn.se

 

Regards,

Jonas

Hi Jonas!

Thanks for your response!

 

Vi have placed an order for the Huwaie E3276-150 4G modem, and once we receive it, will give it another try, as per your suggestion.

I will post back on here whatever the outcome.

 

 

Best regards Peter
