Bonding Policy
•
Round-Robin:
In this case the network interfaces, starting with ETH0, are transmitting sequentially
whereby a distribution of load and a higher tolerance for errors are achieved. In that
mode the network interfaces must be connected to the same network switch.
•
Active Backup:
Only one of two network interfaces is sending and receiving. If an error occurs, the
other network interface assumes responsibility for the process. The network inter-
faces do not have to be connected to the same network switch. From the outside the
MAC address of the association is only visible on one network interface to avoid a
mix-up. This mode supports tolerance for errors.
•
Balance XOR:
Source and target are permanently assigned with one another via the MAC address
of the network interfaces ETH0 and ETH1. The network interfaces must be con-
nected to the same network switch. This mode supports distribution of load and tol-
erance for errors.
•
Broadcast:
In this mode the computer sends its data via all available network interfaces which
enables the use of several network switches. This fact leads to a high tolerance for
errors, but this mode does not enable distribution of load.
•
IEEE 802.3ad Dynamic Link Aggregation:
The network interfaces ETH0 and ETH1 are going to be bundled (Trunking) in this
mode. It is mandatory that the network interfaces are configured with the same
transmission rate and duplex setting. Bundling is made dynamically via the Link Ag-
gregation Control Protocol (LACP). This mode supports distribution of load as well
as tolerance for errors.
The network switch on which the network interfaces ETH0 and ETH1 of
Time Server 8030HEPTA/GPS are connected also needs to be configured
correctly! A wrong configuration can lead to a loss of availability of Time
Server 8030HEPTA/GPS!
