4-Port Serial Device Server with Integrated 4-Port Managed Ethernet Switch
Ethernet Statistics and RMON
ROS provides continuously updating statistics per port
that provide both ingress and egress packet and byte
counters as well as detailed error figures. Also provided
is full support for the RMON statistics, history, alarms,
and event groups. RMON allows for very sophisticated
data collection, analysis and detection of traffic patterns.
Loss of Link Management
Some intelligent electronic devices (IEDs) have dual fiber
optic ports with automatic failover to a backup port should
the primary fail. ROS ensures this mechanism works
reliably under all failure modes by appropriately disabling
link signals when required. ROS also flushes learned
MAC addresses to ensure the failover occurs quickly.
Ethernet Port Security
ROS provides the ability to filter or accept traffic from
specific hosts to prevent unknown users or devices from
gaining access to the network. Unauthorized access
results in the port being shutdown for a period of time
along with SNMP trap and alarm generation.
Broadcast Storm Filtering
Broadcast storms wreak havoc on a network and can
cause attached devices to malfunction. This could be
disastrous on a network with mission critical equipment.
ROS limits this by filtering broadcast frames with a
user-defined threshold.
SNMP (Simple Network Management Protocol)
SNMP provides a standardized method for network
management stations the ability to interrogate devices
from different vendors. ROS supports numerous standard
MIBs (Management Information Base) allowing for easy
integration with any network management system (NMS).
A feature of SNMP supported by ROS is the ability to
generate "traps" upon system events. A NMS can record
traps from multiple devices providing a powerful network
troubleshooting tool. RuggedVue
TM
is RuggedCom’s NMS
that provides graphical visualization of the network and
is fully integrated with all RuggedCom products.
HTML Web Browser and Telnet User Interfaces
ROS provides a simple, intuitive user interface for
configuration and monitoring via a standard graphical
web browser or via Telnet. All system parameters include
detailed on-line help to make setup a breeze. ROS,
presents a common look and feel and standardized
configuration process allowing easy migration to other
RuggedCom managed products.
SNTP (Simple Network Time Protocol)
SNTP automatically synchronizes the internal
clock of all ROS devices on the network. This allows for
correlation of time stamped events for troubleshooting.
Event Logging and Alarms
ROS records all significant events to a non-volatile
system log allowing forensic troubleshooting. Events
include link failure and recovery, unauthorized access,
broadcast storm detection, and self-test diagnostics
among others. Alarms provide a snapshot of recent
events that have yet to be acknowledged by the network
administrator. An extreme hardware relay is de-energized
during the presence of critical alarms allowing an
external controller to react if desired.
Configuration via ASCII Text File
All configuration parameters are stored in an ASCII
formatted text file that can easily be transferred via TFTP
or Xmodem. The configuration file can be saved for
backup purposes and easily manipulated by a text editor.
The text same file can be downloaded to the switch at
a later date in order to re-configure or restore a
previous configuration.
Command Line Interface (CLI)
A command line interface can be used in conjunction
with remote shell to automate data retrieval, configuration
updates, and firmware upgrades. A powerful SQL-like
capability allows expert users the ability to selectively
retrieve or manipulate any parameters the device
has to offer.
