New Features for Cisco IOS XE 17.8.1

This chapter contains the following sections:

Cellular Serviceability Enhancements

Enhancements have been made for cellular and GPS features as follows:

Trigger points and debug code can be enabled via controller cellular CLIs for generating and trap the debug data automatically without manual intervention. The following CLI options are available: 

(config-controller)#lte modem serviceability ?
  gps               GPS debugging
  interface-resets  Interface resets/Bearer deletion
  modem-crash       Modem-crash debugging
  modem-resets      IOS initiated unknown modem-resets

The debug data includes the following:

  • Context Based debug logs (tracebacks, and GPS locations).

  • Well formatted debug messages.

  • Vendor specific debug data at a broader range.

The debug logs are located in the following location of flash:

router#dir flash:servelogs
Directory of bootflash:/servelogs/

GPS and cellular log files are created separately with file names using the timestamp at the time of the creation. These files are created as follows:

  • If the existing file has reached 10Mb, a new file will be created.

  • A new file will be created if the feature (GPS, or cellular) is completely disabled, and then re-enabled.
