896 router cannot synchronize for 100Mbit

Level 1
Level 1

Hello everyone,

i live in germany and i have a new Internet 100mbit from M-net Provider.

i have found that i need the 30a Profile thats why i configure the next command on the controller.

controller VDSL 0
 operating mode vdsl2
 firmware filename flash:VA_B_38V_d24m.bin


and the next commands on the ethernet0.40 because of the tagging to the provider.

interface Ethernet0
 no ip address
interface Ethernet0.40
 description DSL Internet Vlan 40tagged
 encapsulation dot1Q 40
 pppoe enable group global
 pppoe-client dial-pool-number 1



because of the PPPoE i have shutdown the ATM.


although the line is all the time down.

I posted the config from the 897.




just to be sure: you have a standard phone cable connected to the port marked with '12' in the attached image. VDSL uses pins 3 and 4. Have you tried different cables ?

the same cable I connect it and is working on my fritzbox from the provider.

do you think the fritzbox is working with a cable which is not working on cisco router?

and yes i connect to 12 port :)



here is the thing: I have looked at the M-Net website, and it seems that the only device they actually use (and support) is the Fritz!Box (various models of it). The Fritz!Box uses the Qualcomm Atheros and Lantiq/Intel chipsets, while the Cisco 896/897 uses the Broadcom chipset. I am almost certain that the DSLAMs used by M-Net do not support the Broadcom chipsets. Which means that the hardware is simply not compatible.


By the way, I am German myself, so if you feel more comfortable writing in your own language, do so...I don't think anybody else is looking at this thread anyway...

:) if i speak in my own language, you will never understand me :)

i could speak on your own language.


it Is so crazy if that is true. i tried so many upgrades of the firmware so that the chipset to be compatible.

and i have to send it back now, which is difficult because we open the box.


now i have to sell it , if that is true.


and what do you think?

if i go / downgrade from the 100mib to 50Mbit, do i have the same problem? which means my problem is not the profil 30a, but the Chipset of the DSLAM.




like a solution, how do you think if a have a a modem and then try to connect the modem to WAN?
can you please recommend me a modem if that is a solution?


change provider is a bit difficult. 2 years contract. :(
although, i was thinking something else.
i have to connect the router to a friend office, who wants a second internet Line for a backup.
then we will have an other provider, connect him to VDSL from cisco, like a main internet connection and then i will use the mnet like the backup connection.
then comes the question , how to connect the cisco router to the fritzbox?
is it possible to connect the fritzbox to LAN interface from cisco and create a new vlan for that communication?




in theory that would be an option. You would need to add the network that runs on the Cisco to the Fritz!Box so it get NATted on the Fritz!Box, and I am not sure if that is possible.



I have been looking at the Fritz!Box manual, and I think it should be possible to use it as a backup for your Cisco 896/897. It depends on whether you have one or two phone lines available. If you have only one line, you need to use a splitter to connect both devices. What we need to do next is connect the Fritz!Box to one of the GigabitEthernet ports on the Cisco, and when the Cisco connection fails, execute an EEM script on the Cisco that activates the GigabitEthernet port where the Fritz!Box is connected to. It is actually fairly easy to accomplish.


If that is what you want to do, I can work out the configuration.
