9.1.2.7 Miscellaneous
Cluster Multicast Address:
Configuration of the cluster multicast address. Via this address, LANTIME cluster members exchange their
status messages if Multicast mode is selected.
Cluster Port:
Configuration of a free network port for the cluster communication. Per default this port is set to 7000.
DSCP NTP Classification:
DSCP = Differential Service Code Point. DSCP is generally a method for prioritizing the traffic via IP. On the
LANTIME, this setting allows the NTP packets to be assigned to a certain traffic class. The information about
the traffic class is inserted into a header of a IPv4 packet. Routers can evaluate this information and handle
the NTP packets as prioritized.
Bonding-Mode:
In the menu “Network
→
Physical Network Configuration", two or more physical network ports can be grouped
into a bond (group). The Bonding Mode is used to configure either the “ACTIVE BACKUP” or the "LACP" mode
(Link Aggregation Control Protocol), which are supported on the LANTIME.
ACTIVE-BACKUP:
One physical interface in the bonding group acts as an "active slave". All network traffic of a LANTIME Bond
runs through this interface. The other physical interfaces in the bonding group are passive. In case the current
active interface loses the network connection, the passive interface seamlessly takes over. Even the MAC ad-
dress of the network port remains unchanged.
LACP: LACP (802.3ad) allows a combination of multiple physical connections to a logical one. This results
in a load sharing and, in addition, increases the safety in case of a failure compared to "Active Backup". It
is important that other connected network devices also support LACP and the network ports are configured
accordingly.
