C881G-4G-GA-K9 Session disconnect reason codes

[Schwaben_G]

Hi!

I just experienced issues with a  C881G-4G-GA-K9 (no IP-Address on the interface, no service...).

In the output of show cellular 0 all, in the Data Connection Information I got following:

Data Connection Information
===========================
Profile 1, Packet Session Status = INACTIVE
Call end mode = 3GPP
Session disconnect reason type = 3GPP specification defined(6)
Session disconnect reason = Authentication failed(29)

Tried to find out what is the meaning of codes (6 and 29) but without success.

Can anyone help me out?
Thank you in advance!

Hello,

all I could find were some generic 3GPP reason codes that don't help a lot.

Can you post the output of:

sh cellular 0 radio

Hi,

of course, there you are:

LTE Bandwidth = 20 MHz
Current RSSI = -68 dBm
Current RSRP = -0 dBm
Current RSRQ = -0 dB
Current SNR = -18.3 dB

Hi Georg,
I posted the output but without reaction from you...?

Hello,

sorry for my late response. I was checking the RSSI/RSRP/RSRQ/SNR levels, but they all look very good...

As said, the 3GPP disconnect reason is just a generic one. Does this occur often ? If so, turn on debugging (debug cellular 0), also, can you post the output of:

show cellular 0 profile
