9-Port Managed Ethernet Switch with Fiber Optical Uplinks
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.
