Extreme Networks ExtremeWare XOS Command Reference Manual page 970

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
Security Commands
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 view the status of SSH2 on the switch, use the command. The
show management show management
command displays information about the switch including the enable/disable state for SSH2 sessions,
whether a valid key is present, and the TCP port and virtual router that is being used.
Example
The following command generates an authentication key for the SSH2 session:
configure ssh2 key
The command responds with the following messages:
WARNING: Generating new server host key
This will take approximately 10 minutes and cannot be canceled.
Continue? (y/n)
If you respond yes, the command begins the process.
To configure an SSH2 session using a previously generated key, use the following command:
configure ssh2 key pregenerated 2d:2d:2d:2d:20:42:45:47:
Enter the previously-generated key (you can copy and paste it from the saved configuration file).
