Ethernet redundancy
SETTING UP AN ETHERNET CONNECTION
To modify the IP addresses of the CPUM, the net.cfg file must be edited, for example,
using the CPUM Configurator software (see 6 CPUM Configurator and 6.8 Changing the IP
address of a VM600 rack (CPUM card)) or a terminal emulation session (see 7 Terminal
emulation and 7.10 Changing the IP address of a VM600 rack (CPUM card)).
As shown in Figure 4-6 (top), the parameters displayed in the CPUM Configurator’s CPUM
TCP-IP Configuration dialog box correspond to the CPUM card’s Ethernet interfaces as
follows:
• Primary Ethernet Controller for the primary network interface (ETH1).
• Secondary Ethernet Controller for the secondary network interface (ETH2).
Editing the values in CPUM Configurator changes the values in the underlying net.cfg file.
As shown in Figure 4-6 (bottom), the parameters displayed in the net.cfg file correspond
to the CPUM card’s Ethernet interfaces as follows:
• #main network connection and net0_… for the primary network interface (ETH1).
• #redundant network connection and net1_… for the secondary network interface
(ETH2).
For additional information on the net.cfg file, see 3.4.2 About the net.cfg file.
