
Jetter Ethernet system bus multicast frames which are received on a port
are not forwarded to any of the other ports.
 All other Ethernet frames are forwarded as usual.
Purpose:
This command lets you prevent forwarding Jetter Ethernet system bus
multicast frames to the CPU and the other ports. This way, networks are split
and thus data traffic - e.g. from the machine network to higher-level networks -
is reduced.
Address space
Splitting is carried out on Ethernet level via the multicast address range of the
Jetter Ethernet system bus.

Enable JetSync blockage for port X15
Effect:
 The JetSync blockage is enabled for port X15 only. Bit 8 in R 202962 is
set.
 Jetter Ethernet system bus multicast frames of the CPU are forwarded to
port X14 only.
 Jetter Ethernet system bus multicast frames of port X14 are forwarded to
the CPU only.

Jetter Ethernet system bus multicast frames of port X15 are forwarded to
the CPU and to port X14.
 All other Ethernet frames are forwarded as usual.
