Having finally purchased myself the necessary HWIC (VA-DSL-A) I'm now having a hell of a time setting it up. I'm trying to get it to work on bt infinity 2.

Looking at it,I don't think it's my config that's the issue, I think that it's firmware related. Having said that, I'm no expert in this so cannot be certain.

This is the main bit of the config for running the interfaces:
Code:

Currently I'm seeing this in the console shortly after bootup
Code: 
VDSL_DAEMON-3-INITFAIL: VDSL Daemon Boot init retries done max times init failed.


sh controller vdsl 0/0/0 gives the following output:
Code: 
Controller VDSL 0/0/0 is DOWN

Daemon Status:           Start

DSL modem is not yet initialized.

OS FW           embedded        VDSL_LINUX_DEV_01212008 (1)

sh flash gives:
Code:

2         3064 Mar 3 2014 20:10:24 +00:00 cpconfig-19xx.cfg


I've since added a firmware for the card (though it's pretty old)
Code: 
1     68923232 Mar 3 2014 20:02:30 +00:00 c1900-universalk9-mz.SPA.152-4.M5.bin
2         3064 Mar 3 2014 20:10:24 +00:00 cpconfig-19xx.cfg
3      2602194 Apr 6 2019 15:15:08 +00:00 vdsl.bin-A2pv6C033c_d23e


and then set it as follows:
Code: 
controller VDSL 0/0/0
 operating mode auto
 firmware filename flash:/vdsl.bin-A2pv6C033c_d23e


Having done all that, sh controller vdsl 0/0/0 still shows exactly the same as above. I've acquired an image for IOS 15.7 (c1900-universalk9-mz.SPA.157-3.M2.bin) and tried that along with a much later firmware for the card (va_a_39t_b_38r1_24o.bin) and it is still behaving as above.

This is my original working config with the separate OR modem.

Am I doing something wrong here or is it likely to be a duff card?

There's a UK flag that can be set on the controller which may or may not help you, 'modem ukfeature'.

Thanks for the suggestion, caged. Sadly I've tried that earlier this evening, having found reference to it elsewhere relating to the 887VA.

This is now the config that it's running from. I'm still getting the same output for sh controller vdsl 0/0/0 with no modem FW or modem phy

The card's interfaces are ATM0/1/0 and ethernet0/1/0 but the card controller is VDSL 0/1/0. If the card is in slot 0 they are all 0/0/0, moving it to slot 1 changed them all to 0/1/0. I didn't modify the config before moving the card to the other slot, hence the invalid inputs.
 
The symptoms and the lack of a modem FW, modem PHY and Vendor version suggest a hardware issue to me, so I've contacted the seller. Hopefully I'll be able to sort out a replacement.
 
Replacement arrived yesterday. Will be testing it out this evening. I've got my fingers crossed I've not been one of "those guys" and this one initialises and works perfectly.
 
I've fitted the replacement modem and re-applied my config and it worked first time, although I had some issues with a lot of websites timing out. I think that may have been caused by my not having "ip tcp adjust-mss 1452" on interface GigabitEthernet0/1. It used to be set at 1350. It all seems to be working perfectly since I put it back in.

Seeing this controller info was the best thing in the world.

I've got the feeling that some of the config has been lost over the last few months as ACL 2 doesn't look right to me. Anyone spot anything daft in the config, let me know. I realise I've never bothered to setup users on it as it's never really bothered me.

I have no idea if that Cisco supports baby jumbo frames, but the Openreach VDSL infrastructure does. I can run full 1500 byte packets over a Vodafone business FTTC link by setting the interface MTU to 1508.

Well I've seen others mention it elsewhere, so I've given it a go. Not had any issues so far.

Tweaked config.

I've tried this on mine and get "timeout while retrieving stats". Trying to run xdslctl on the router via telnet outside of exec results in the following message.

Code: 
Cisco-1921>xdslctl
test vdsl 0/0/0 modem exec /bin/xdslctl
  ^
% Invalid input detected at '^' marker.


My config contains the two lines:
Code: 
service internal
alias exec xdslctl test vdsl 0/0/0 modem exec /bin/xdslctl

Is this your problem? Try checking the box 'requires command to enter shell' and use 'en' in your settings, I think you have to be in privileged mode for it to work. :D

Is that what you meant by "outside of exec”

That is what I meant. I’d already tried using en command to enter shell but dslstats then has problems logging in. I tried to set something in special login options but it didn’t work. It’d be nice to know what @iwrox did with special login.
