SSH Protocol has been upgraded in 09.0.10d release to resolve the SSH vulnerabilities detected by NESSUS tool. SSH service disconnection in expected with SSH client that uses SSH-RSA host key only.

Symptoms
SSH service disconnection. Older SSH clients that support only SSH-RSA host key will not connect to ICX running with 09.0.10 firmware version.

WORKAROUND
Use TELNET or CONSOLE to access/manage the device.

CORRECTIVE ACTION
SSH client upgrade that supports SSH-RSA2-256 or SSH-RSA2-512 for authentication
