Function
•
Integrated redundancy manager for constructing ring topol-
ogies with up to 10 Gbps and high-speed media redundancy.
By interconnecting the ends of an optical or electrical line
to form a ring, reliable communication can be achieved.
The redundancy manager (RM) integrated in the
SCALANCE XR-500 switch monitors the function of the
network. It recognizes the failure of a transmission link or of a
SCALANCE X switch in the ring and activates the substitute
path within a maximum of 200 milliseconds.
•
Redundant Layer 2 interfacing to company networks;
SCALANCE XR-500 switches support the standardized
redundancy procedures Multiple Spanning Tree Protocol
(MSTP), Rapid Spanning Tree Protocol (RSTP), and Spanning
Tree Protocol (STP). This enables a subnet to be connected
redundantly to a higher-level corporate network with reduced
requirements for the reconfiguration time (in the order of
seconds).
•
The Layer 3 switching functions (optional) enable simple
subdivision of large networks into smaller subnets with their
own address space. Reasons for subdivision into subnets
include separation of the Ethernet network to reduce the
broadcast load, separation of sensitive areas from the main
network, and subdivision of the network into logical working
groups.
•
Redundant Layer 3 connection to corporate networks;
SCALANCE XR-500 switches support the standardized
routing protocols Open Shortest Path First (OSPF) and
Routing Information Protocol (RIP), and the standardized
routing procedure Virtual Router Redundancy Protocol
(VRRP). This means industrial, routed subnets can also be
connected redundantly to a higher-level corporate network.
•
Thanks to support for the Dual Stack Routing function, both
IPv4 addressing and IPv6 addressing can be operated in one
network.
•
Support of virtual networks (VLAN);
for structuring Industrial Ethernet networks with a fast growing
number of users, a physically existing network can be divided
into several virtual networks. Port-based, protocol-based and
IP-based VLANs are available for selection.
•
Load limiting when multicast protocols (e.g. video trans-
mission) are used;
through learning the multicast receivers (IGMP Snooping,
IGMP Querier), SCALANCE XR-500 switches can also filter
multicast data traffic and therefore limit the load in the network.
Multicast and broadcast traffic can be limited.
•
Time synchronization;
diagnostic messages (log table entries, e-mails) are time-
stamped. The local time is standardized throughout the
network by means of synchronization with a SICLOCK time
transmitter or SNTP/NTP server, thereby simplifying the
assignment of diagnostic messages of several devices.
•
Link Aggregation (IEEE 802.3ad) for bundling data streams
•
Quality of Service (IEEE 802.1Q) for prioritization of network
traffic
