Eltex MES2424

Hello.
I ran into a problem trying to make a backup from the eltex2424 switches
There are no problems when working with 3324 and 2348 series switches. 2424 switches connected to the same network with similar settings do not work
At the same time, in the AAA logs, I see that oxidized successfully connects and performs a “show run”, but the data does not reach the server

Hello. Had the same problem. Solved it by fixing the eltex profile that uses oxidized to work. The MES2424 uses a different command to display the entire configuration. Add to eltex.rb “set cli pagination off” and “set cli prompt off” as “show running-config”. Good luck!
