2-Port Serial Device Server with up to 3 Ports Managed Ethernet Switch

ROS Features

Serial IP Encapsulation

that are 'pruned' to prevent loops. eRSTP yields worst-case

fault recovery1 of 5ms times the 'bridge diameter' and allows

Many 'legacy' devices (RTU, PLC, IED, etc.) only support

serial communications via RS232, RS422 or RS485. ROS™

encapsulates the serial data within a TCP connection allowing will have fault recovery times under 50ms. eRSTP implements

rings of up to 80 switches. For example, a ring of ten switches

these devices to be reached via an IP network. A wide range

of baud rates, frame packetization options, and diagnostics

allows any serial protocol to function. The RS416 has specific

support for the following serial protocols:

ꢀ Raw Socket serial encapsulation

ꢀ Modbus TCP (client and server)

ꢀ DNP 3

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).

ꢀ WIN and TIN

ꢀ Microlok

MODBUS TCP

The Modbus protocol is ubiquitous in the industrial control

and automation world. ROS converts Modbus RTU

master/slave serial data packets to Modbus TCP client/server

packets for transmission over an IP network. This allows

communications to Modbus RTU slaves via Ethernet and

allows multiple masters to poll the same slave device.

A configurable "weighted fair queuing" algorithm controls how

frames are emptied from the queues.

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:

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.

ꢀ Passwords - Multi-level user passwords secures switch

against unauthorized configuration

ꢀ SSH / SSL - Extends capability of password protection to

add encryption of passwords and data as they cross

the network

ꢀ Enable / Disable Ports - Capability to disable ports so that

traffic can not pass

Link Aggregation (802.3ad)

ꢀ 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 - Provides centralized password management

ꢀ SNMPv3 - encrypted authentication and access security

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:

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

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

2-Port Serial Device Server with up to 3 Ports Managed Ethernet Switch

ROS Features

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.

ꢀ 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.

SNMP (Simple Network Management Protocol)

SNMP provides a standardized method for network

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.

management stations the ability to interrogate devices from

different vendors. SNMP versions supported by ROS™ are

v1, v2c, and v3. SNMPv3 in particular provides security

features (such as authentication, privacy, 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). 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. RuggedVueTM is RuggedCom's

NMS that provides graphical visualization of the network

and is fully integrated with all RuggedCom products.

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.

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.

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.

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.

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.

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.

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.

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.
