Dear all,
I want to ask about RADIUS. In the radius menu there is a menu accounting-backup. The default value is no. If i change it to yes, can i know where’s the file backup??
“accounting-backup (yes | no; default: no) - this entry is a backup RADIUS accounting server”
Thx all

There is no backup file. Backup means the accounting records will
also be sent to an additional, second radius server (this is the “backup server”).

Okay. so where i set the second radius server (this is the “backup server”) ? in mikrotik or in my radius server primary?
And how to change the default value “accounting-backup” to “yes” ?
–accounting-backup (yes | no; default: no)–
Maybe that could be clear
Thx
Use ‘radius’ menu to set 'accounting-backup=yes/no.
‘radius add accounting-backup=’.
Note, it is not possible authenticate to both radius server at the same time, only if first
fails it will go to the second or if you want to use the second radius for
accounting backup purposes.
You can create a radius client with accounting-backup enabled and move it
above the primary radius server.
If you want to use it as a backup radius server then you should add
another entry after the main radius entry.
Okay, but where i can set the secondary radius???
if i set accounting backup to ‘yes’, it’s just enable to yes, but how mikrotik now that there is a secondary radius, for example ip radius primary is 10.0.0.1 & secondary i set 10.0.0.2?
As I said specify the primary first at the list and secondary as secondary. Look at the previous post more carefuly.
