3G USB modem on SRX devices

[kza]

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

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

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

Thanks for your answers,

but do you think it will work as well on SRX240 ?

thanks to let me know

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

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.

hi dfex

Can I have the the configs of SRX for the 3G usb modem. also I need to know a stand alone SRX210 with 3G express card will work in Australia Optus network. Has anyone tried that out.

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:
