Example: Software upgrade with the sw command
The following sequence of commands depicts a typical upgrade procedure using the sw
command. This example uses freely available client software to manage the process:
PuTTY for the SSH client to make an Ethernet connection to the CLI and psftp for an sftp
client to make a secure file transfer.
1. Login to the Multinet4 CLI and use the ssh show command to make sure that
your SSH server is running (that is, that an SSH key has been generated).

If the ssh show command does not show the result displayed in Figure 5-4 use the ssh
keygen command to generate an SSH key.
2. View the current software upgrade state. In the Multinet4 CLI run the sw show
command to view the current software upgrade state. Figure 5-5 illustrates a
typical system before the beginning of the upgrade process.

When the sw show command displays an
