• Enhanced Rapid Spanning Tree Protocol (eRSTP)™
Siemens's eRSTP allows the creation of fault-tolerant ring and mesh Ethernet networks that incorporate
redundant links that are pruned to prevent loops. eRSTP implements both STP and RSTP to promote
interoperability with commercial switches, unlike other proprietary ring solutions. The fast root failover feature
of eRSTP provides quick network convergence in case of an RSTP root bridge failure in a mesh topology.
• 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. RUGGEDCOM ROX II supports
Class of Service, which allows time critical traffic to jump to the front of the queue, thus minimizing latency and
reducing jitter to allow such demanding applications to operate correctly. RUGGEDCOM ROX II 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. RUGGEDCOM ROX II 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.
• Simple Network Management Protocol (SNMP)
SNMP provides a standardized method for network management stations to interrogate devices from different
vendors. RUGGEDCOM ROX II supports v1, v2c and v3. SNMPv3 is generally recommended, as it provides
security features (such as authentication, privacy, and access control) not present in earlier SNMP versions.
RUGGEDCOM ROX II also supports numerous standard MIBs (Management Information Base) allowing for easy
integration with any Network Management System (NMS). A feature of SNMP supported by RUGGEDCOM ROX
II is the ability to generate traps upon system events. RUGGEDCOM NMS, the Siemens 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 Siemens products.
• Remote Monitoring and Configuration with RUGGEDCOM NMS
RUGGEDCOM NMS (RNMS) is Siemens's Network Management System software for the discovery, monitoring
and management of RUGGEDCOM products and other IP enabled devices on a network. This highly
configurable, full-featured product records and reports on the availability and performance of network
components and services. Device, network and service failures are quickly detected and reported to reduce
downtime.
RNMS is especially suited for remotely monitoring and configuring RUGGEDCOM routers, switches, serial servers
and WiMAX wireless network equipment. For more information, contact a Siemens Sales representative.
• NETCONF Configuration Interface
The NETCONF configuration interface allows administrators to set device parameters and receive device updates
through the use of XML-based commands. This standard, supported by multiple vendors, makes it possible to
greatly simplify the task of network management.
For more information about how to use NETCONF to configure RUGGEDCOM ROX II, refer to the RUGGEDCOM
RUGGEDCOM ROX II NETCONF Reference Guide available on https://www.siemens.com/ruggedcom.
• NTP (Network Time Protocol)
NTP automatically synchronizes the internal clock of all RUGGEDCOM ROX II devices on the network. This allows
for correlation of time stamped events for troubleshooting.
