How to continiously write syslog to flash?

[JuergenW]

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!

As per IOS XE it should work, what is the version of IOS XE running on this ASR, what is the error you getting ?

below command reference :

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

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]
