Solved: adsl wic is DOWN DOWN all the time.

Francis Garcia · ‎12-10-2009

Hi Folks,

I got a 1760 router with 2 adsl wics, but what happens is that both cards are always- down - down -, even if I execute the -no shutdown- command in the interface mode.Here you got some commands.

I want to know why it behaves like this, because I want to mount my adsl services over this router since a month ago but I always got a new trouble.

Giuseppe Larosa · ‎12-11-2009

Hello Francis,

if the interface is up/up now clearly there is OSI layer1 compatibility and yes ADSL2+ is backward compatible with ADSL.

If your provider is using MER you need a different configuration.

saying that MER is like RFC 1483 bridging means:

IPv4/Eth/AAL5/ATM/DSL

your current configuration is classic IP over ATM:

IPv4/AAL5/ATM/DSL

a possible configuration that can help is the usage of IRB, integrated routing and bridging

int eth0

no ip address

bridge-group 1

int atm1/0

no ip address

int atm1/0.1 point-to-point

no ip address

bridge-group 1

pvc 8/35
encapsulation aal5snap

in BVI1

! set here the ip address

ip address

bridge 1 protocol ieee

bridge 1 route ip

ip route 0.0.0.0 0.0.0.0 BVI1

there is a more compact configuration using RBE, but this is more easy to understand at first.

to see RBE

https://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a0080093e5f.shtml

PVC 8/35 is typically used for bridged implementation on Alcatel based chipset.

Hope to help

Make sure you have read: http://www.cisco.com/en/US/docs/routers/access/1700/software/feature/guide/1700ADSL.html

There's a few potential causes. The first is that you may need to have a special crossover cable to bring up your DSL. I found this was common when I was deploying home-offices with routers handling the ADSL. You need a CAB-ADSL-RJ11X= if you have a DSL filter/splitter in the wall. From Cisco Docs:

"Cable Information

The straight-through cable is the default cable and is included in the WIC packaging. For customers that have an external splitter, please order the crossover cable. This crossover cable can be ordered as a spare with the product id: CAB-ADSL-RJ11X="

Another callout to this same cable:

"If you are connecting a Cisco 1700 series router with an ADSL WIC to an RJ-11 wall jack that has the ADSL pair wired for pins 2 and 5, you must use the lavender crossover cable with the blue stripe. The crossover cable is orderable as a spare."

Second, can you please provide a configuration dump so we can examine your config? Who is your provider, and what information have you collected to configure the interface? You usually need the VPI and VC numbers from your provider to configure the pvc on the interface, as well as if you are going to be using bridged ethernet or ppp on the circuit. You also need to know if they are using aal5snap or another encapsulation type.

I'll assist you further once you respond with the additional information. Please rate if this helps you.

Cheers,

Tim

Hello Francis,

I've searched with feature navigator at

http://www.cisco.com/go/fn

search by feature: ADSL

I would try with a newer IOS image like

c1700-sy7-mz.124-25a.bin

I had similar problems with a C3640 some mounths ago.

Hope to help

Giuseppe

Francis Garcia · ‎12-10-2009

Hi folks,

After I upgrade the IOS to the c1700-sy7-mz.124-25a.bin I have this result.

Router#show ip inter brief
Interface IP-Address OK? Method Status Prot
ocol
ATM0/0 unassigned YES NVRAM down down

FastEthernet0/0 unassigned YES manual up up

ATM1/0 unassigned YES NVRAM initializing down

Now just stay initializing all the time. There is something that I want to explain.

My ISP is using a method called MER because I got a ADSL modem that was running that protocol, I want to replace it for the cisco 1760 but I don't know what is the equivalent of this for cisco, if u can plz can help me with some guideline or template.

Giuseppe Larosa · ‎12-11-2009

Hello Francis,

MER is a type of encapsulation that should match with RFC 1483 bridged or RBE in cisco terms with ethernet frames carried inside AAL5 PDUs.

In your case you have a problem at OSI physical layer (lower level)

Verify with your provider specification what type of ADSL they provide:

ADSL

ADSL2 not backward compatible to ADSL

ADSL2+ backward compatible to ADSL

your WIC should support ADSL not ADSL2. So if DSLAM is ADSL2 there is an issue.

Hope to help

Hi giuslar,

I think that your answer is logic, thanks, then... Can my Wic be operable with adsl2+ then? I'm using this configuration in the interface and is up up but there is not transmition, I cannot even make ping to the ip address of the interface interface. What do u think?

interface ATM1/0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM1/0.1 point-to-point
ip address xxx.xxx.xxx.xxx
pvc 8/35
encapsulation aal5snap

Regards,

Francis

Thank you soooo much Giuslar,

I have configured the the router like this and It worked.

!
interface ATM1/0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM1/0.1 point-to-point
bridge-group 1
pvc 8/35
encapsulation aal5snap
!
!
interface BVI1
ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx
