Requirements For Installation And Operation - Siemens SCALANCE XB-200 Configuration Manual

Description

2.3 Requirements for installation and operation

● Virtual networks (VLAN)
To structure Industrial Ethernet networks with a fast growing number of nodes, a physical
network can be divided into several virtual subnets.
● Load limitation when using multicast and broadcast protocols, for example video
transmission
By learning the multicast sources and destinations (IGMP snooping, IGMP querier), IE
switches can filter multicast data traffic and so reduce the load in the network. Multicast
and broadcast data traffic can be limited.
● Time-of-day synchronization
Diagnostics messages such as log table entries, e-mails are given a time stamp. The
local time is uniform throughout the network thanks to synchronization with a SICLOCK
time transmitter or SNTP/NTP server and therefore makes the identification of diagnostics
messages of several devices easier.
● Quality of Service for classification of the network traffic is according to CoS (Class of
Service - IEEE 802.11Q) and DSCP (Differentiated Services Code Point - RFC 2474)
● Port mirroring
Mirroring allows the data traffic of a port to be mirrored at another port (monitor port). The
data traffic can then be analyzed at this monitor port without any effects on the data
traffic.
● Network access protection complying with the standard IEEE 802.1X
Ports can be configured for end devices that support authentication according to IEEE
802.1X. The authentication is made via a RADIUS server that must be reachable over the
network.
● Log table
The log table logs events that occur during operation. The user can specify which events
cause an entry in the table.
● Link aggregation (IEEE 802.1AX) for bundling ports (SCALANCE XC-200/SCALANCE
XP-200)
2.3 Requirements for installation and operation
Requirements for installation and operation of the IE switches
A PG/PC with a network connection must be available in order to configure the IE switches.
An IP address must be assigned to the IE switch and it must be available in the network, see
also "Initial assignment of an IP address (Page 16)".
