Re: Disabling a WIC-3G?

ashkentapa · ‎09-12-2010

Hi all.

A number of my remote sites have been converted from wireless wan links (via HWIC-3G-GSM cards) to wired wan links. The 3G WICs are still in the routers and due to their remoteness are likely to stay there. I've removed all the wireless configuration that I can find:

interface Cellular0/0/0
no ip address
encapsulation ppp
shutdown
!

line 0/0/0
exec-timeout 0 0
no exec

Router#sh cellular 0/0/0 profile
* - Default profile

However the logs keep filling up with these messages:

Sep 13 14:35:08 AEST: %CELLWAN-2-MODEM_DOWN: Cellular0/0/0 modem is DOWN
Sep 13 14:35:22 AEST: %CELLWAN-2-MODEM_UP: Cellular0/0/0 modem is now UP
Sep 13 14:36:06 AEST: %CELLWAN-2-MODEM_DOWN: Cellular0/0/0 modem is DOWN
Sep 13 14:36:20 AEST: %CELLWAN-2-MODEM_UP: Cellular0/0/0 modem is now UP
Sep 13 14:37:04 AEST: %CELLWAN-2-MODEM_DOWN: Cellular0/0/0 modem is DOWN

What else do I need to do to disable the 3G WICs? Thanks.

Hi,

Can you send the full configuration to see what else might be in there.

Thanks

Hi,

Can you try by switching off GSM Radios through gsm radio off command or by removing modem profiles?

http://www.cisco.com/en/US/docs/routers/access/1800/1861/software/feature/guide/mrwlsgsm.html

Regards...

-Ashok.

With best regards...

Hi Ashok.

Thanks for your suggestions. I've already tried deleting the modem profile but it didn't stop the errors. As you can see from the output below there are no remaining cellular profiles:

ROUTER#sh cellular 0/0/0 profile
* - Default profile
ROUTER#

I've tried to turn off the radio but I can't access the controller in order to run the command. I can do a "sh controller" on it:

ROUTER#show controllers cellular 0/0/0

Interface Cellular0/0/0
HSDPA/UMTS/EDGE/GPRS-850/900/1800/1900/2100MHz unit 0,
HWIC cellular modem configuration:
---------------------------
etc...

But I can't enter controller configuration mode:

ROUTER(config)#con?
config-register configuration connect control-plane

ROUTER(config)#

So I can't actually run the "gsm radio off" command. The routers are 1841s with wic-3g-gsm WICs in them. There must be some other method for accessing the cellular controller on these boxes. I'll keep looking. Thanks.

james.mirtsis · ‎09-13-2010

Sometimes the commands are hidden, have you tried typing the full command regardless of whether it shows up on the help?

ROUTER(config)#controller cellular 0

also do a show priv, you will need to be priv 15. The only other way to shut it down is to remove it from the chasis.

ashkentapa · ‎09-13-2010

Hi James.

Thanks for your response. I am indeed running at privilege level 15:

ROUTER#sh priv
Current privilege level is 15

Yet the "controller" command is not available:

ROUTER(config)#controller cellular 0
^
% Invalid input detected at '^' marker.

I think I'm just going to have to get used to seeing those errors in the logs
