SSH client of switch stops working for the current session after executing Python script

[Erik_Auerswald]

The SSH client available on EXOS stops working for the current session after executing the Python script "mlag_config_check.py" (from https://github.com/extremenetworks/ExtremeScripting/tree/master/EXOS/Python/mlag_config_check). Logging out and then back in again resolves the issue.

The same happens after running the script "show_port_vid.py" (from https://github.com/extremenetworks/ExtremeScripting/tree/master/EXOS/Python/show_port_vid), so it seems to be a problem with running (Python) scripts, not with the individual script that first showed the problem.

Reported here as asked on https://github.com/extremenetworks/ExtremeScripting .

Observed on an X620-16t switch with EXOS version 21.1.1.4-patch1-2.

Hi Erik, I just took ownership of this case. I'll be reaching out shortly.

Well that doesn't sound good. Opening a case is the right path for this one. Thanks Erik.
