Cisco 887VA can't connect to DSL

dmorenolop · ‎04-02-2011

Hello, I'm trying to get an internet connection through my cisco 877va but I can't get access. I cant apply show cotroller vdsl 0 command and I can see DSL up, however, the dialer0 interface can't get access to internet. If I apply "show int dialer0 account" coomand, I get the next message: "No traffic sent or received on this interface".Here is my configuration:

Hi,

You also need a NAT statment and a default route

ip nat inside source list 105 interface dialer0 overload

access-list 105 permit ip 10.10.10.0 0 0.0.0.255 any

ip route 0.0.0.0 0.0.0.0 interface dialer0

Hi Reza, of course I've done that: Here it is:

ip forward-protocol nd
ip http server
no ip http secure-server
!
!
ip nat inside source static udp 10.10.10.0 80 interface Dialer0 80
ip nat inside source route-map SDM_RMAP_1 interface Dialer0 overload
ip route 0.0.0.0 0.0.0.0 Dialer0
ip route 10.10.10.0 255.255.255.0 Dialer0 permanent
!
logging esm config
access-list 1 permit 10.10.10.0 0.0.0.255
access-list 141 permit ip any any
dialer-list 1 protocol ip permit

The problem is DSL interface, it seems ATM0.1 never shows itself up. This interface always be down, do you know why?

Thank you

Hi there,

Would it be possible for you to please post the following outputs from the router when it is connected to the DSL line:

- show dsl int atm 0
- show atm vc
- show pppoe sessison

Thank you.

Cheers,

Yanil

dmorenolop · ‎04-04-2011

Hi yzeledon.

Due the version and model's router I think the "show dsl int atm 0" doesn't work. This model (887VA) has a controller called VDSL so I'm sending the following output "show controller VDSL 0":

yzeledon · ‎04-04-2011

Hi,

No show dsl int atm0, what IOS version are you running? Although I did see something that capture my attention under "show pppoe session" (mac address information displays only 0’s):

Uniq ID PPPoE RemMAC Port VT VA State

SID LocMAC VA-st Type

N/A 0 0000.0000.0000 ATM0.1 Di0 N/A PADISNT

0000.0000.0000 VC: 0/35

So we are not getting anything from that PVC, if you don’t mind forwarding me a few more outputs:

debug atm events

debug atm errors

show ip int brief

show int atm 0

show atm int atm 0

Thank you for your time.

Cheers,

Yanil

Hi again yzeledon, the IOS version is 15.1 It's the newest (I think)

You're right, the pppoe shows 0 on MAC address, it is strange, is'nt it?

Hi,

Look at the following:

000235: *Apr 4 21:25:52.680: ATM: vci 35, vpi 0, index 3 is incorrect

Nice!

Although I got a question for you, Are you configuring this router for VDSL (on which you don't need the ATM interface) or for ADSL2? Please confirm.

Cheers,

Yanil

dmorenolop · ‎04-04-2011

Hi!!, I am configuring the router for ADSL2, trough pppoe

Regards

yzeledon · ‎04-05-2011

Hi,

For some reason I’m kind of thinking the line is configure for VDSL and not ADSL2/2+ as the ATM int is not coming up, plus the errors on the debugs… Can we remove the configuration out of the ATM interface and configure VDLS to test if it trains up?

You can use the following configuration:

!

interface Ethernet0

description $ES_WAN$$FW_OUTSIDE$

no ip address

no ip route-cache cef

no ip route-cache

pppoe-client dial-pool-number 1

no fair-queue

!

interface Dialer0

ip address negotiated

no ip redirects

no ip unreachables

no ip proxy-arp

ip mtu 1452

ip flow ingress

ip nat outside

ip inspect DEFAULT100 out

ip virtual-reassembly in

encapsulation ppp

dialer pool 1

dialer-group 1

ppp authentication chap pap callin

ppp chap hostname dmorenol

ppp chap password 7 08324D420B181718

ppp pap sent-username dmorenol password 7 0017120A065A1909

no cdp enable

!

Let me know how things work.

Hi,

I'm facing exactly the same problem. I've tried all the solutions posted in this forum but nothing!

Can anybody help me please?

Regards,

mjnbacordo · ‎02-14-2012

Hello, i have a small question. Since 887VA model is a multimode dsl/router, how to identify the mode configured on the dslam side? When you configure this device to "auto" mode, it trains up automatically to the mode configured on the dslam side -- either adsl2/2+ or vdsl2.

I'm reading the datasheet and it says that,

ATM WAN Interface - ADSL 1/2/2+ mode

Ethernet WAN Interface - VDSL2 mode

Is this something we need to know (on the CPE side) so we would know which WAN interface (ATM or Ethernet) to configure to connect to the internet?

Thanks a bunch.

I'm running VDSL2 on an 887VA with BT Infinity, the config is here on my blog :

Let me know if that helps, or if you have any questions reply here or post a comment.

Hi,

http://www.cisco.com/en/US/docs/ios/11_3/feature/guide/vcinteg.html

take away oam-pvc manage and check again the PVC. it looks like a mismatch between the two ends.
