ISR 1100 no IP address on Cellular Interface

[ben222]

Hi everyone,

I am trying to get LTE running on ISR 11xx routers.

Old config (dialer interface with "dialer pool" command and the cellular interface with "dialer pool-member" command) ist not working.

As I read there is new way to configure that.

That is what I tried:

TEST#cellular 0/2/0 lte profile create 1 internet.telekom

conf t

controller Cellular 0/2/0
lte modem link-recovery rssi onset-threshold -110
lte modem link-recovery monitor-timer 20
lte modem link-recovery wait-timer 10
lte modem link-recovery debounce-count 6

interface cellular 0/2/0
ip address negotiated
dialer in-band
dialer watch-group 1
dialer idle-timeout 0
dialer-group 1
pulse-time 1

ip route 0.0.0.0 0.0.0.0 cellular 0/2/0
dialer-list 1 protocol ip list 1
access-list 1 permit any

dialer watch-list 1 ip 5.6.7.8 255.255.255.255
dialer watch-list 1 delay route-check initial 60
dialer watch-list 1 delay connect 1

Unfortunately I am not getting an IP address assigned.

Modem is up:

TEST#sh cel 0/2/0 radio
Radio power mode = online
LTE Rx Channel Number = 1600
LTE Tx Channel Number = 65535
LTE Band = 3
LTE Bandwidth = 20 MHz
Current RSSI = -58 dBm
Current RSRP = -87 dBm
Current RSRQ = -8 dB
Current SNR = 11.8 dB
Physical Cell Id = 92
Number of nearby cells = 4
Idx PCI (Physical Cell Id)
--------------------------------
1 92
2 12
3 322
4 432
Radio Access Technology(RAT) Preference = LTE
Radio Access Technology(RAT) Selected = LTE

But I am not getting a connection:

TEST#sh cel 0/2/0 network
Current System Time = Sun Jan 6 2:3:22 1980
Current Service Status = No service
Current Service = Unknown
Current Roaming Status = Roaming
Network Selection Mode = Automatic
Network = o2 - de
Mobile Country Code (MCC) = 262
Mobile Network Code (MNC) = 3
Packet switch domain(PS) state = Not attached
LTE Carrier Aggregation state = Deconfigured
Registration state(EMM) = Not registered
EMM Sub State = Limited Service
Tracking Area Code (TAC) = 0
Cell ID = 0
Network MTU = Not Available

Any ideas how to fix that?

What commands am I missing?

Thank you very much in advance.

Kind Regards

Ben

Hello,

try the simplified configuraion below, then ping 8.8.8.8.

interface cellular 0/2/0
ip address negotiated
ip nat outside
dialer in-band
dialer idle-timeout 0
dialer-group 1
pulse-time 1
!
ip nat inside source list 1 interface Cellular0/2/0 overload
ip route 0.0.0.0 0.0.0.0 cellular 0/2/0
dialer-list 1 protocol ip permit
access-list 1 permit any

Hi Georg,

thanks for your quick response.

Unfortunately it's still not working.

Same output on the cel 0/2/0 network, no ip adress assigned, all pings failing.

Actually the cellular interface is in state down/down.

How do I get that into up/up state?

[Georg Pauwen]

Hello,

what is the output of:

show cellular 0/2/0 profile

Try the dialer watch below:

lte modem link-recovery rssi onset-threshold -110
lte modem link-recovery monitor-timer 20
lte modem link-recovery wait-timer 10
lte modem link-recovery debounce-count 6
!
interface cellular 0/2/0
ip address negotiated
ip nat outside
dialer in-band
dialer watch-group 1
dialer idle-timeout 0
dialer-group 1
pulse-time 1
!
ip route 0.0.0.0 0.0.0.0 cellular 0/2/0
dialer-list 1 protocol ip permit
access-list 1 permit any
!
dialer watch-list 1 ip 8.8.8.8 255.255.255.255

Hi,

#sh cel 0/2/0 profile
Profile password Encryption level = 7

Profile 1 = INACTIVE* **
--------
PDP Type = IPv4
Access Point Name (APN) = internet.telekom
Authentication = None

* - Default profile
** - LTE attach profile

Configured default profile for active SIM 0 is profile 1.

I applied the config you provided.

One thing I noticed now:

Most of the time, the cellular interface is down/down. But from time to time it is up for a very short time, displaying the following:
Cellular0/2/0 is up (spoofing), line protocol is up (spoofing)

Hello,

can you issue the exec command:

test cellular 0/2/0 modem-power-cycle

and post the output ?

[ben222]

are you able to use that sim from a mobile? does it have PIN?

do you have your ISP SIM APN details?

cellular 0/2/0 lte sim unlock <PIN>
cellular 0/2/0 lte profile create 1 <APN (i.e. apn.movistar.com)> <pap/chap> <user> <pass> ipv4

yes

yes

controller Cellular 0/2/0
lte sim data-profile 1 attach-profile 1 slot 0 ! in case this is the slot you have the sim in

..

and the rest is said here already.

[ben222]

Hi,

sim is working in another device.

There is no PIN assigned at the moment.

ISP SIM APN details are configured.

I also did 

"controller Cellular 0/2/0
lte sim data-profile 1 attach-profile 1 slot 0"

--> command is accepted, but i cannot see it in running config (neither in show run all)

[Georg Pauwen]

Hello,

since you say the interface comes up from time to time, can you turn on:

debug modem
debug cellular 0 messages callcontrol

and post the output ?

[ben222]

hello,

*Jul 16 16:57:03: debug information ipc sent successfully

[Georg Pauwen]

Hello,

there is definitely something wrong with your SIM card.

The output of:

TEST#sh cel 0/2/0 network

should render:

Current Service Status = Normal

Try to configure auto-sim:

TEST#conf t
TEST(config)#controller cellular 0/2/0
TEST(config-controller)#lte firmware auto-sim

Wait for 5 minutes, then power cycle the modem:

TEST#test cellular 0/2/0 modem-power-cycle

Hey,

well, the sim was used before in another device.

So actually it should be working.

I tried "lte firmware auto-sim", but no changes.

I will be some days off, but after I will test the sim inside a smartphone again to check if it's still working.

Maybe I will even try another router just to be sure.

I will write back here if I got some new information.

Thank you so far.

Hello,

it is possible that the provider has tied the SIM to the MAC address of the old device, for security purposes. It might be worth checking with your provider if that is the case...
