Increasing the reliability of network connections through link
aggregation
In the default settings, you can use both network interfaces at the same time to
access the web application from two different network segments, for example.
To increase the reliability, the network interfaces can be grouped through link aggre-
gation. Only one interface is active within the group. Another interface only becomes
active if the active interface fails.
We provide two different modes to monitor the interfaces:
MII mode:
The carrier status of the network interface is monitored through the
Media Independent Interface. This mode only checks the function of the network inter-
face.
ARP mode:
The address resolution protocol sends requests to an ARP target within the
network. The answer of the ARP target confirms both the functionality of the net-
work interface and the proper network connection to the ARP target.
If the ARP target is connected to the network but is temporarily offline, requests
cannot be answered. Define multiple ARP targets to receive an answer from at least
one target if an ARP target fails.
How to configure the settings of grouped network interfaces:
1. Click the tools symbol in the toolbar.
2. Click the
Network > Link aggregation
tab.
3. Enter the following data into the
Network
paragraph:
NOTE:
MII
and
ARP mode
cannot be combined.
NOTE:
According to RFC 3330, the Link Local address space 169.254.0.0/16 is
reserved for the internal communication between devices. An IP address of this
addres space cannot be assigned.
Name:
Enter a name for the group of network interfaces.
Operational
mode:
Choose the operational mode for the grouped network inter-
faces:
Off:
disables link aggregation.
Use the »Interfaces« tab to configure the network interfaces.
Static:
A static IP address is assigned.
DHCP:
obtain IP address from a DHCP server.
IP address:
Enter the IP address of the interface (only if you have
selected the Static operational mode).
Netmask:
Enter the netmask of the network (only if you have selected
the Static operational mode).
