3G Configuration on 819 Router

_yzenezy_ · ‎01-09-2013

Hi,

I have a 819 Router (C819HG-U-K9) and I'm trying to get the 3G connection up. I have followed this thread which was a great help but so far I'm still unable to get a connection to my carrier:

https://supportforums.cisco.com/message/3824614#3824614

The 3G cell network seems to be ok:

#sh cell 0 network

Current Service Status = Normal, Service Error = None

Current Service = Combined

Packet Service = HSPA (Attached)

Packet Session Status = Inactive

Current Roaming Status = Home

Network Selection Mode = Automatic

Country = AUS, Network = Optus

Mobile Country Code (MCC) = 505

Mobile Network Code (MNC) = 2

Location Area Code (LAC) = 33320

Routing Area Code (RAC) = 1

Cell ID = 38469

Primary Scrambling Code = 384

PLMN Selection = Automatic

Registered PLMN = , Abbreviated =

Service Provider = YES OPTUS

I can even send and receive SMS's on the cell network.

Our carrier (Exetel) does not require a username/password so they are not set in the profile:

#show cellular 0 profile 1

Profile 1 = INACTIVE*

--------

PDP Type = IPv4

Access Point Name (APN) = exetel1

Authentication = None

Username:

Password:

* - Default profile

This is what I get when I attempt a manual start-chat:

I've tried lots of different configuartions so I may have left something undone or done that shouldn't be. Have I overlooked something simple? Any assistance is apreciated.

Thanks in advance,

Cisco Configuration Professional (Cisco CP) is installed on this device

and it provides the default username "cisco" for one-time use. If you have

already used the username "cisco" to login to the router and your IOS image

supports the "one-time" user option, then this username has already expired.

You will not be able to login to the router with this username after you exit

this session.

It is strongly suggested that you create a new username with a privilege level

of 15 using the following command.

Replace <myuser> and <mypassword> with the username and password you

want to use.

Shameless bump on my part. Has anyone a few clues for me?

Peter Paluch · ‎01-10-2013

Hello Tom,

Try changing the encapsulation on your Cellular0 interface from ppp to slip, i.e.

interface Cell0

encapsulation slip

The documentation appears to indicate that for the basic communication with the cellular controller, we need to speak plain serial data which is exactly the SLIP. Then please post the output of the debug again. Thank you!

Best regards,

Peter

_yzenezy_ · ‎01-10-2013

Hi Peter,

Thanks for your reply.

I did try this before but got an unexpected response:

muddy#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

muddy(config)#interface cellular 0

muddy(config-if)#encapsulation slip

Cellular0: Only PPP encapsulation supported

muddy(config-if)#

Seems I can set slip on this interface. Any idea why? Is there some other configuration I need to make first?

I suppose this information is useful:

muddy#show inventory

Is this an HSPA+7 modem? Shoul I be using a different chat-script?

Kind regards,

_yzenezy_ · ‎01-10-2013

Ok,

I've worked out this is not an HSPA+ modem.

With the chat script:

chat-script gsm "" "ATDT*99*1#" TIMEOUT 60 "CONNECT"

It appears to make a connection but I get no IP Address:

Hi,

Well I seem to be making more progress but I'm still stuck. I remind you that my carrier expects an APN only; no username or password are expected. With some routing and a ping I see the following:

Hi All,

I've worked out that the peer is looking for a username on my router called UMTS_CHAP_SRVR:

Configuring a username:

has done the trick!

This helped immensely:

Thanks to Peter Paluch for his tip. Even though you didn't 'answer' my question, you gave me some focus. I would give you some credits if I knew how.

Thanks and I hope this helps someone else.

Kind regards,

Hi Guys,

I had the same issue with a separate 3G module on 888G.

Thought to share as below worked for me,

cellular 0 gsm profile create 1 telstra.internet chap '' ''

chat-script INTERNET "" "ATDT*99*1#" TIMEOUT 30 "CONNECT"

interface Cellular0
no ip address
encapsulation ppp
dialer in-band
dialer pool-member 1
async mode interactive

interface Dialer1
ip address negotiated
encapsulation slip
dialer pool 1
dialer idle-timeout 0
dialer string INTERNET
dialer persistent
!

ip route 0.0.0.0 0.0.0.0 Dialer1

line 3
script dialer INTERNET

I`m posting this for future reference.

I encountered the same problem as _yzenezy_

Configuration was as follows:

chat-script DIAL "" "ATDT*99***1#" TIMEOUT 30 "CONNECT"
!
interface Cellular0
 ip address negotiated
 ip mtu 1530
 ip nat outside
 encapsulation ppp
 dialer in-band
 dialer pool-member 1
 async mode interactive
!
interface Dialer1
 mtu 1530
 ip address negotiated
 ip nat outside
 ip virtual-reassembly in
 encapsulation ppp
 load-interval 30
 dialer pool 1
 dialer idle-timeout 0 either
 dialer string DIAL
 dialer persistent delay initial 10
 dialer persistent delay 10
 dialer-group 1
 no cdp enable
!
dialer-list 1 protocol ip permit
!
line 3
script dialer DIAL

cellular 0 gsm profile create 1 MY_APN

There was no connection

debug ppp negotiation showed this

*Feb  6 06:56:37.903: Ce0 PPP: Phase is AUTHENTICATING, by the peer
*Feb  6 06:56:37.903: Ce0 CHAP: Redirect packet to Ce0
*Feb  6 06:56:37.903: Ce0 CHAP: I CHALLENGE id 1 len 35 from "UMTS_CHAP_SRVR"
*Feb  6 06:56:37.903: Ce0 LCP: State is Open
*Feb  6 06:56:37.903: Ce0 CHAP: Unable to authenticate for peer
*Feb  6 06:56:37.903: Ce0 PPP DISC: User failed CHAP authentication

I tried configuring hostname AND password on my dialer interface as _yzenezy_ said:

interface Dialer1
 ppp authentication chap callin
 ppp chap hostname UMTS_CHAP_SRVR
 ppp chap password 0 UMTS_CHAP_SRVR

Since the connection was unsuccessful, i continued with removing hostname and PAF it connected! So, the final config on my dialer interface is:

interface Dialer1
 mtu 1530
 ip address negotiated
 ip nat outside
 ip virtual-reassembly in
 encapsulation ppp
 load-interval 30
 dialer pool 1
 dialer idle-timeout 0 either
 dialer string skripta
 dialer persistent delay initial 10
 dialer persistent delay 10
 dialer-group 1
 ppp authentication chap callin
 ppp chap password 0 UMTS_CHAP_SRVR
 no cdp enable

Profile 1 = ACTIVE*
--------
PDP Type = IPv4
PDP address = 10.169.129.129
Access Point Name (APN) = MY_APN
Authentication = None
Username:
Password:

Hope this helps someone out there!

Cheers,

Tom
