Compatibility of configuration files on SG300 series vs. hardware version or model number

[fmarshall]

I have a number of SG300 switches ranging from -10 to -52 with quite a few -20s.

The hardware versions vary.\

What can be said about using configuration files between hardware versions?

With the same firmware?

With different firmware?

I see that the new configuration files are .txt files.  That's good!  It suggests a level of commonality.  But what does that really mean?

Hello,

Using one configuration file between different models is not highly recommended. 

The difference between hardware versions is number of VLANs supported, number of MAC addresses supported - more information can be found in the release notes for each firmware. So, different hardware versions will not be such a problem.

If you anyways decide to try with one config file on different models - it is better to have them all upgraded to the same firmware version, as there you may have differences in settings/features.

Also, another thing if you decide to try it - you may configure the settings that will be equal across all switches, upload the configuration and then configure the differences on each manually - for example, assigning VLANs to ports, applying port security, etc.
