We're currently unable to deploy new firmware to our AOS S switches (2930F/2530 confirmed; 5406R zl2 needs testing).
IMC is perfectly able to access the switch (SSH/SNMP) and is even able to run commands on the switch, but it runs into a timeout before even opening the SFTP session (confirmed on the switch log).
After investigating imcupgdm-log it seems that imc is not sending any response to the "Do you want to save the current configuration (y/n)?" prompt:
2026-06-10 09:19:47.870 [INFO (0)] [THREAD(18304)] [CSSHService::executeCmd()] lastLine is Do you want to save the current configuration (y/n)?
2026-06-10 09:45:45.482 [INFO (0)] [THREAD(9400)] [qvdm::QvGetLogFileSize] get file size from qvdm.conf: 50
18304 is the thread ID for the firmware deployment task, and that's the last message appearing in the log considering this thread.
Doing it manually via, e.g., pscp on the IMC server works totally fine. That further seems like the problem is neither the network nor the switch but IMC itself.
Is anyone else experiencing this?
