RS940G
8-Port Managed Gigabit Ethernet Switch, 128-bit Encryption
A feature of SNMP supported by ROS ® is the ability to generate
“traps” upon system events. RuggedNMSTM, the RuggedCom
management solution, can record traps from multiple devices
providing a powerful network troubleshooting tool. It also
provides a graphical visualization of the network and is fully
integrated with all RuggedCom products.
1 eRSTP fault recovery times may be approximated as follows:
For 100 Mbps, fault recovery performance is <5ms/hop
For 1,000 Mbps, fault recovery performance is <5ms/hop + 20ms
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.
SCADA and Industrial Automation
ROS ® contains features that optimize network performance and
simplify switch management based on the unique requirements
found in SCADA and industrial automation applications. Features
such as Modbus TCP management for retrieval of switch data
using the ubiquitous Modbus protocol and DHCP Option 82,
a Rockwell Automation ODVA requirement for IP address
assignment based on the location of the end device, provide
capabilities not found in typical “commercial” or “office grade”
Ethernet switches.
Port Based Network Access Control (802.1x)
ROS ® supports the IEEE 802.1x standard that defines a
mechanism for port-based network access control which
provides a means of authenticating and authorizing devices
attached to LAN ports.
Port Rate Limiting
ROS ® supports configurable rate limiting per port to limit unicast
and multicast traffic. This can be essential to managing precious
network bandwidth for service providers. It also provides edge
security for denial of service (DoS) attacks.
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.
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.
Port Mirroring
ROS® can be configured to duplicate all traffic on one port to a
designated mirror port. When combined with a network analyzer,
this can be a powerful troubleshooting tool.
Port Configuration and Status
ROS ® allows individual ports to be ‘hard’ configured for speed,
duplex, auto-negotiation, flow control and more. This allows
proper connection with devices that do not negotiate or have
unusual settings. Detailed status of ports with alarm and SNMP
trap on link problems aid greatly in system troubleshooting.
Port Statistics and RMON (Remote Monitoring)
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.
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 external hardware relay is de-energized during
the presence of critical alarms allowing an external controller to
react if desired.
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.
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 same text 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.
