ROS Features
Cyber Security
Cyber security is an urgent issue in many industries where
advanced automation and communications networks play
a crucial role in mission critical applications and where high
reliability is of paramount importance. Key ROS features that
address security issues at the local area network
level include:
■ Passwords – Multi-level user passwords secures switch
against unauthorized configuration
■ SSH / SSL – Extends capability of password protection
to add 128-bit encryption of passwords and data as they
cross the network
■ Enable/Disable ports – Capability to disable ports so
that traffic can not pass
■ 802.1Q VLAN – Provides the ability to logically segregate
traffic between predefined ports on switches
■ MAC based port security – The ability to secure ports
on a switch so only specific Devices / MAC addresses
can communicate via that port
■ 802.1x Port based network access control – The ability
to lock down ports on a switch so that only authorized
clients can communicate via this port
■ RADIUS – authentication service using MD5 hash and
providing centralized password management
■ SNMPv3 – encrypted authentication access security and data encryption (CBC-DES with 56-bit encryption key)
■ Secure socket layer – Web-based management using
SSL with data encryption (128-bit encryption key)
■ RSA – 1024 bit key for key management and key
exchange
■ TACACS+ – Terminal Access Control and Accounting Services. Client provides encrypted authentication
and authorization
■ Point to Point (PPP) – using CHAP (MD5 Hash)
authentication service
■ SFTP – Secure File Transfer Protocol using SSH encryption
The ROS cyber security features are included to help address
the various industry specific security standards such as
NERC CIP, ISA S99, AGA 12, IEC 62443, ISO 17799:2005
and PCSRF SPP-ICS.
Enhanced Rapid Spanning Tree Protocol
(eRSTP)
RUGGEDCOM eRSTP allows the creation of fault-tolerant
ring and mesh Ethernet networks that incorporate
redundant links that are ‘pruned’ to prevent loops. eRSTP
yields worst-case fault recovery1 of 5ms times the ‘bridge
diameter’ and allows rings of up to 160 switches. For
example, a ring of ten switches will have fault recovery
times under 50ms. eRSTP implements both STP and
RSTP to ensure interoperability with commercial switches
unlike other proprietary ‘ring’ solutions.
Quality of Service (IEEE 802.1p)
Some networking applications such as real-time control
or VoIP (voice over IP) require predictable arrival times for
Ethernet frames. Switches can introduce latency in times
of heavy network traffic due to the internal queues that
buffer frames and then transmit on a first come first serve
basis. ROS supports ‘Class of Service’ in accordance with
IEEE 802.1p that allows time critical traffic to jump ahead
to the front of the queue thus minimizing latency and
reducing jitter to allow such demanding applications to
operate correctly. ROS allows priority classification by
port, tags, MAC address, and IP type of service (ToS). A
configurable “weighted fair queuing” algorithm controls
how frames are emptied from the queues.
VLAN (IEEE 802.1Q)
Virtual local area networks (VLAN) allow the segregation
of a physical network into separate logical networks with
independent broadcast domains. A measure of security is
provided since hosts can only access other hosts on the
same VLAN and traffic storms are isolated. ROS supports
802.1Q tagged Ethernet frames and VLAN trunks. Port
based classification allows legacy devices to be assigned to
the correct VLAN. GVRP support is also provided to simplify
the configuration of the switches on the VLAN.
Link Aggregation (802.3ad)
The link aggregation feature provides the ability to
aggregate several Ethernet ports into one logical link (port
trunk) with higher bandwidth. This provides an inexpensive
way to set up a high speed backbone to improve network
bandwidth. This feature is also known as “port trunking,”
“port bundling,” “port teaming,” and “Ethernet trunk.”
IGMP Snooping
ROS uses IGMP snooping (Internet Group Management
Protocol v1&v2) to intelligently forward or filter multicast
traffic streams (e.g. MPEG video) to or from hosts on the
network. This reduces the load on network trunks and
prevents packets from being received on hosts that are
not involved. ROS has a very powerful implementation
of IGMP snooping that:
■ Can be enabled on a per VLAN basis
■ Detects and filters all multicast streams regardless of whether subscribers exist
■ Supports “router-less” operation by supporting an
“active” mode
■ Restores traffic streams immediately after an RSTP
topology change
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

RUGGEDCOM RS940G
8-port Managed Gigabit Ethernet Switch, 128-bit Encryption
ROS Features
SNMP (Simple Network Management Protocol)
Loss of Link Management
SNMP provides a standardized method for network
management stations to interrogate devices from different
vendors. SNMPv3 in particular provides security features
such as authentication, privacy with data encryption (CBC-DES
with 56-bit encryption key) and access control not present in
earlier SNMP versions. ROS also supports numerous standard
MIBs (Management Information Base) allowing for easy
integration with any network management system (NMS).
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.
A feature of SNMP supported by ROS is the ability to
generate “traps” upon system events. RUGGEDCOM NMS,
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.
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.
8-port Managed Gigabit Ethernet Switch, 128-bit Encryption
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/SSH User
Interfaces
ROS provides a simple, intuitive user interface for configuration
and monitoring via a standard graphical web browser or via
Telnet/SSH. 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, SFTP 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.
