Hi Antero,

I have a feeling that your SSH process has locked up. There were a few SSH bugs in the 30.6 and early 30.7.1 releases; See the 'resolved issues' section of the release notes and search 'ssh'. I think you're likely hitting EXOS-26898 which I have seen multiple times.
https://documentation.extremenetworks.com/release_notes/ExtremeXOS/30.7.2-Patch1-33/downloads/ExtremeXOS_30.7.2-Patch1-33_RelNotes.pdf

You can try to correct with 'restart process exsshd' but this may cause the switch to crash. A reboot would definitely fix things in the short term, but I would recommend upgrading to the latest 30.7.2 patch when you can to completely resolve this issue.

Hope that helps!

Hi there, could you let us know which model switch you are having this issue with? Also, when did you first notice this issue happening?
