Outlines troubleshooting procedures for LTE modem crashes, identifying common issues, diagnostics, and corrective steps to resolve connectivity or operational failures.
In the event that an LTE modem crashes, crash dump is the information stored in the device bootflash that:
-
makes troubleshooting easier by appearing in the admin-tech file
-
helps diagnose the cause of the crash
When enabled, this command instructs the device to automatically collect a crash dump from the LTE modem upon a crash event. This dump contains various diagnostic logs and memory states that are essential for analyzing why the modem crashed.
Before you begin
Ensure that the device has sufficient bootflash storage available to accommodate the large amount of data collected.
Procedure
Use the lte modem crash-action auto-collect command to automatically gather and store detailed operational data in the event of an LTE modem crash. |

Device#show cellular 0/2/0 logs modem-crashdump
Modem crashdump logging = off
Device#When a crash-dump is in progress, it is displayed as follows:
Router#show cellular 0/3/0 logs modem-crashdump
Modem crashdump logging = on
Progress = 44%
Router#
Router#show cellular 0/3/0 logs modem-crashdump
Modem crashdump logging = on
Progress = 98%
Router#show cellular 0/3/0 logs modem-crashdump
Modem crashdump logging = offOnce the collection is complete, the status will return to off.
