Usage Guidelines
Secure Shell 2 (SSH2) is a feature of ExtremeWare that allows you to encrypt session data between a
network administrator using SSH2 client software and the switch or to send encrypted data from the
switch to an SSH2 client on a remote system. Configuration and policy files may also be transferred to
the switch using the Secure Copy Program 2 (SCP2)
SSH2 functionality is not present in the base ExtremeWare XOS software image, but is available as an
additional, installable module. Before you can access any SSH2 commands, you must install the module.
Without the module, the SSH2 commands do not appear on the command line. To install the module,
see the instructions in Appendix A, "Software Upgrade and Boot Options."
After you have installed the SSH2 module, you must generate a host key and enable SSH2. To generate
an SSH2 host key, use the

An authentication key must be generated before the switch can accept incoming SSH2 sessions. This can
be done automatically by the switch, or you can enter a previously generated key.

configuration to preserve the key.
