How to continiously write syslog to flash?

Hello All,

 

on our Cisco 3650 switches I can easly and continiously write the syslog to the local flash file system with the command "logging file flash:systemlog 409600 informational". But this does not work on an ASR 1001-X router.

 

How can I continiously write the syslog to flash?

 

Thanks!

Juergen

I belive you need to use below command to work for you.

 

 logging buffered [buffer-size | severity-level]

 logging persistent [url harddisk:/directory] [size filesystem-size] [filesize logging-file-size]

The version is: Cisco IOS Software [Fuji], ASR1000 Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 16.9.3, RELEASE SOFTWARE (fc2).

 

And here the error:

router #condig)#logging file flash:systemlog 409600 informational
                                     ^
% Invalid input detected at '^' marker.
