<pre wrap="">Hi,
Really interesting! Could you tell us which sierra module version are
you using? (modinfo sierra)
I cannot help you with the newtork redundancy problem, but it would be
interesting to know how to solve it.

<pre wrap="">Dear all,
after some challenges with installing the necessary modules for the new
Sierra Wireless MC8700 embedded modem on ALIX 6b2 I got the modem now up and
the new Direct IP interface working.
Here is briefly how it was done, and there is two questions left to you
gurus too.
So, if Direct IP is new to you too, its is a very very cool new feature in
the newest Sierra modems. You can connect directly to 3G modem without using
ppp at all!
Here is the story:
1. I installed new sierra and sierra_net modules to Voyage, and they seem
OK:
voyage:~# lsmod |grep sierra
sierra_net 8580 0
usbnet 12040 1 sierra_net
sierra 11144 0
usbserial 24368 1 sierra
usbcore 103996 7
sierra_net,usbnet,sierra,usbserial,ohci_hcd,ehci_hcd
2. The new usb0 interface gets up and IP addresses from the operator:
voyage:~# ifconfig usb0
usb0 Link encap:Ethernet HWaddr ba:36:0c:7f:01:07
inet addr:85.77.195.36 Bcast:85.77.195.36 Mask:255.255.255.255
inet6 addr: fe80::b836:cff:fe7f:107/64 Scope:Link
UP BROADCAST RUNNING NOARP MULTICAST MTU:1500 Metric:1
RX packets:207 errors:0 dropped:0 overruns:0 frame:0
TX packets:380 errors:0 dropped:5 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:43510 (42.4 KiB) TX bytes:30174 (29.4 KiB)
3. As the last step I changed NAT'ing eth0 from eth1 to usb0 and after that
it works nicely.
Then the questions:
1. At boot there is a notification about invalid interface number and
missing interface number (lines 2 and 3 below). Is this a problem and is
there something I could do?
[ 11.020832] usb 2-3: new high speed USB device using ehci_hcd and address
2
[ 11.137442] usb 2-3: config 1 has an invalid interface number: 7 but max

[ 15.913781] usbcore: registered new interface driver sierra
[ 15.914781] sierra: USB Driver for Sierra Wireless USB modems: v.1.7.8
[ 16.136390] usb0: register 'sierra_net' at usb-0000:00:0f.5-3, Sierra
Wireless USB-Ethernet Modem, 86:bc:8a:7a:01:07
[ 16.137781] usbcore: registered new interface driver sierra_net
done.
2. Would it be possible to configure ADSL and 3G (eth1 and usb0) to be used
simultaneously as each others backups? I.e. in case of one interface failing
the other one gets active and returns when the preferred interface is up
again.
Best regards
Anttu
