3G USB modem on SRX devices

Hi,

 

I've read on internet that it could be possible to connect a 3G USB modem directly on SRX device (without the use of CX111). Is there an update which allows this functionnality (I've read about 10.4R6)

 

Thanks for infos

Re: 3G USB modem on SRX devices

I think 11.2R2 would be the primary target release for these modems.

Re: 3G USB modem on SRX devices

Hi Iza,

 

Yes - Sierra Wireless 3G USB Modems are supported on the SRX210 under 10.4R6.  So far I have tested the USB306, 310U and 312U and they all work fine.

 

Download the release notes for 10.4R6, because there are a couple of things you need to do first (upgrade RE firmware, plus add a chassis command), but once that is all done and you've rebooted, the USB cards will be detected as a cl-0/0/8 interface, just like the Express Card slot would be.  Configuraiton is identical.

 

It's a really neat solution!

 

Hope this helps

Re: 3G USB modem on SRX devices

Any idea if there are pre-paid providers that these devices work on?  I'd like to pick up one to use in my home lab for testing

Re: 3G USB modem on SRX devices

I'm almost positive this is SRX210 only, but when I get some time I'll run some testing.

 

As for pre-paid, I don't see why not - as long as the modem is one of the supported Sierra Wireless ones, you should be fine.

 

I also heard that the complete list of supported modems will be made available in the 10.4R7 release notes when it's available.

Re: 3G USB modem on SRX devices

Hi Lushan,

 

Yes - I'm based in Australia, and I've tested this on both Telstra and Optus.  Be aware though that most modems that Optus provide are Huawei (and won't work).  The only Sierra modem they supply is the 310U:

The configuration is the same as you would use for the 3G Express card, which is documented in the Knowledge Base:

Re: 3G USB modem on SRX devices

Hi dfex,

 

In our testing with Telstra Ultimate (U312) using dialer-filter to initiate the dial-out, after the call times out, the modem became unresponsive.

 

Below is the respond of the "show modem wireless interface" command (it took a while to come back with the incomplete output).

 

root@SRX210> show modem wireless interface cl-0/0/8 Wireless modem firmware details

  Card type: (null)

  Modem manufacturer: Sierra Wireless, Inc

  Current modem temperature: 0 deg C

  International mobile equipment identity

            (IMEI): (null)

  Modem PIN security status: Enabled

  SIM status: SIM Okay

  SIM lock: Unlocked

  SIM user operation needed: No Op

  Retries remaining: 0

Radio statistics

  Current radio signal strength: -0 dB

 

----------------

 

I'm wondering if you've seen this. If you have, what do you do to get the modem to respond again? (other than rebooting the router)

Better yet, do you know why the modem behaved like this?

 

The modem seems to be doing this intermittently.

 

Any input would be very much appreciated.

Re: 3G USB modem on SRX devices

Hi Guys,

 

So just to confirm that, SRX 3G support is only with Sierra modems and it won't work with any other 3G modems cause I've tested this and it didn't recognized the card.

 

Thanks

Re: 3G USB modem on SRX devices

Hi,


The modem I'm using is a Sierra Wireless.

 

Anyway, JTAC has found that there's a memory buffer leak with using the 3G modem (regardless whether it's USB modem or an Express Card), in which memory buffer is not being released after use and caused it to fail after several dial-out.

 

They've got a fix and it will be released soon.

 

 

Cheers,
Sari

Re: 3G USB modem on SRX devices

Is the Sierra Wireless 313U (also known as the AT&T USBConnect Momentum 4g) supported on the srx210?  If I can skip the CX111 and just use the SRX USB port that would be helpful.

Re: 3G USB modem on SRX devices

[ Edited ]

Hi mysterx,

 

My understanding is that Junos 10.4R6 and above can handle any Sierra Wireless 3G USB modem (SRX 210 and 110 only).

 

I've tested 3 Sierra Wireless USB modems (312u, 319u and 308u) and they all worked.

 

I'm not familiar with 313u... if it's LTE (4G) modem then it is not yet supported.

 

P.S. When using 3G USB modem on SRX 210 or 110, please note there's the memory buffer leak bug which causes the modem to stop dialing out after several times of successful dialing. The fix is going to be corporated in Junos 11.4R2, which is due in Mid Feb, I am told.

Re: 3G USB modem on SRX devices

I guess the momentum isn't supported.  I upgraded the srx to 10.4r8.5 and the bios to 2.1. I then added that chassis command to enable support for modems on usb port 1. I saw cl-0/0/8 in the interfaces list. However, with the card in the srx210, I reboot, after the reboot the status shows that the srx is still waiting for a card. 

 

Oh well Smiley Happy.

Re: 3G USB modem on SRX devices

Hi kza,

 

3G modem is only supported on SRX 100, 110, 210.

 

Nothing above SRX 210.

Sari
