Enabling SSH
Starting with SFTOS 2.5.1.1, you no longer need to generate the SSH keys off-line. Before you enable the
SSH server, NVRAM does not contain the keys, as shown (or not shown, in this case) in Figure 9-106.
After you enable the SSH server and the SSH keys are automatically generated, the keys will not be
deleted even if SSH is disabled later. See Figure 9-107 on page 142.
