19-Port Modular Managed Ethernet Switch with Gigabit Uplink Ports, 128-bit Encryption
SNMP (Simple Network Management Protocol) (cont’d)
A feature of SNMP supported by ROS ® is the ability to generate
“traps” upon system events. RuggedNMS™, 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.
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.
