Hallo, I want to write an export script to reuse the exported settings with other hardware. Because of hardware specific things like MAC-Address I want to filter such things like the MAC. First step I need is the text of the export command is saved to a variable. But how? The following simple cod…

Not directly related to the question, but if you’re going to create a full configuration export as a final goal, that’s likely going to be larger than 4096 bytes, which is the size limit for RouterOS variables.

You can’t store the direct export as a variable, but… you can obtain the same output using print as-value. The below code will output wireless interface settings to file(s). Each file can be independently run using ‘/import’. Also, if a file would exceed 4096 bytes, it increments to the next fil…

Hallo dssmiktik, thank you for your script. Its an interesting way to export settings and I think its a good way to filter parts which I don’t need to export. I think that will help me a lot! Thank you!! :slight_smile:

there is limitation on how large strings can be assigned to variable, that limit is 4KB 4096 bytes.

janisk, What is the allowed length of a comment field (in bytes)? Maybe I should check for variable length would exceed 4096, then dynamically allocate the next available variable (var1, var2, var3, etc…, just like I have with files? Unfortunately, the RouterOS scripting language and limited (no…

comment field can be longer than string you can save in variable.

Someone please test this code: :global vartest :foreach i in="111111111111111112222222222222222223333333333333333333333333311111111111111112222222222222222223333333333333333333333333311111111111111112222222222222222223333333333333333333333333311111111111111112222222222222222223333333333333333333333…

Hallo, yes it seems to work. My ouput of the terminal with version 3.30 is .. 10320 10320 ABCDEFG It also seem to work with a local variable! Nice! :slight_smile:

correction. that 4KB limitation is there if you want to save and read from file, if you want to set or read variables and it is not connected with files, only router memory is your limiting factor. (as it seems now - long, from C)

save export to variable

Yes 4096 could be too little.

Is it possible when I export to a file to delete some strings (for example mac addresses) in the file?

Comments as variables?

Script to set gw for bunch of IPs?
