Network Duplexing

Network duplexing is described here.
2.1

Overview

This system duplicates the network by using the bonding function.
Network duplication is achieved by pairing network interfaces of PCI slots in CPU/IO module 0 and network
interfaces in the same PCI slots in CPU/IO module 1. For this server, network interface names are based on the
naming convention as described in the table below.


Do not change the network interface name.
Important

IPv6 is not supported.

Do not set each network from the commands (nmcli, etc.) related to NetworkManager
that comes with OS. Be sure to use the vndctl command as subsequently described if
setting the IP address, subnet mask, default gateway, etc. Set other network setting
items manually by referring to the online manual of the man command.
If the unused network port is displayed as an abnormal in the monitoring software, connect
Tips
the pair of unused ports by the LAN cable, and set the dummy fixed IP address to enable
the coupled interface. Refer to "Chapter 1 (8.7 Problems With Bundled Software)".
The bonding mode is not limited. The default setting is active-backup(mode=1).
