1.1.4. Updates Occur In Real Time
All configuration and display menus present the current values, automatically updating if
changed from other user interface sessions or SNMP. All statistics menus will display changes
to statistics as they occur.
1.1.5. Alarm Indications Are Provided
Alarms are events for which the user is notified through the Diagnostics sub-menu. All
configuration and display menus present an indication of the number of alarms (in the upper
right hand corner of the screen) as they occur, automatically updating as alarms are posted
and cleared.
1.1.6. The CLI Shell
The user interface provides a Command Line Interface shell for operations that are more easily
performed at the command line. You may switch back and forth from the menu system and
shell by pressing <Ctrl-S>. For more information on the capabilities of the shell please refer
to
Chapter 5, Using the CLI Shell

1.2. The ROS® Secure Shell Server
1.2.1. Using a Secure Shell to Access the User Interface
SSH (Secure Shell) is a network protocol which provides a replacement for insecure remote
login and command execution facilities, such as telnet and remote shell. SSH encrypts traffic
in both directions, preventing traffic sniffing and password theft.
SSH protocol version 2 is implemented in ROS®. The authentication method is “keyboard-
interactive” password authentication. A user logged in via SSH has the same privileges as
one logged in via the console port.
1.2.2. Using a Secure Shell to Transfer Files
ROS® implements an SFTP server via SSH to transfer files securely. The file system visible
on the RuggedSwitch® has a single directory. The files in it are created at startup time and
can be neither deleted nor renamed. Existing files can be downloaded from the switch. For
example, firmware images may be downloaded for backup and log files may be downloaded
for analysis. Some files may be overwritten by uploading a file of the same name to the switch,
as would be done in order to upgrade the firmware.
The implemented commands are:
dir/ls
list directory contents
get
download a file from the switch
put
upload a file to the switch
