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 4 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.
