    What is the Extreme SSH default RSA KEY size?

    What commands to use?
    Thank you so much for your response and any reply or attempt to help will be appreciated.

    Paul,

    Is the key associated with SSH or SSL? If the key is available, the top half of the key will display the key length. A Hex to ASCII converted can be used to get this information. A pregenerated key in EXOS shows a value of 2048 bit as shown below which would be default.

    ---- BEGIN SSH2 ENCRYPTED PRIVATE KEY ----
    Subject: root

    ........

    If SSL is enabled, the 'show ssl' command will provide the RSA key length in the output. The 'show sshd2 user-key' command may also provide some insight.
