The key generation process generates the SSH2 private host key. The SSH2 public host key is derived
from the private host key and is automatically transmitted to the SSH2 client at the beginning of an
SSH2 session.
To enable SSH2, use the following command:
enable ssh2 {port <tcp_port_number>} {vr [<vr_name> | all | default]}
You can also specify a TCP port number to be used for SSH2 communication. By default the TCP port
number is 22.
Before you initiate a session from an SSH2 client, ensure that the client is configured for any non-default
access list or TCP port information that you have configured on the switch. Once these tasks are
accomplished, you may establish an SSH2-encrypted session with the switch. Clients must have a valid
user name and password on the switch in order to log in to the switch after the SSH2 session has been
established.
To view the status of SSH2 sessions on the switch, use the show management command. The show
management
command displays information about the switch including the enable/disable state for
SSH2 sessions and whether a valid key is present.
