Traffic segregation

SMV messages causing high traffic should be filtered out so that they do not reach network
devices which do not subscribe to SMV messages. This is done in managed Ethernet switch
configuration which must be configured to perform the filtering operation. Traffic over
Ethernet network is grouped into several virtual LANs.
– VLAN ID = 1
– VLAN ID = 1 000
– VLAN ID = 3 000 – 3 511

1V LG 5 000 07 E
(MMS, IEEE 1588, SNMP, ...). It exists as default and its usage
throughout LAN yields the same behaviour as if there were no
VLANs (VLAN ID = 0)
(GOOSE messages)
(SMV stream). It is grouped based on sender and associated
receivers.
