Description
Hi All,
I'm using a Cisco vios_l2-ADVENTERPRISEK9-M in a eve-ng environment and i could not establish a full SSH session to the vSwitch. i could see the SSH negotiation start through console logging on the switch but it times out and disconnects the sessionwith an error. i have tried the following remedies, but with no positive outcome:
- i have issued: Get-SSHTrustedHost | Remove-SSHTrustedHost
- Get-SSHSession was clear.
- i've tested this on PS v5.1 and v7 but none of them worked.
- SSH connection is working fine with Putty.
- i've used the -AcceptKey:$true and -Force switches but none of them worked.
Did anyone come across this issue before ?
Thanks for your help!!

Done means identifying a supported compatibility fix or documenting the required change.
