Description of each component is as follows:

<Virtual interface information>

Setup the followings for the number of virtual interfaces.

Virtual interface name(T-1)

Specify a name for a virtual interface, which will be assigned to the physical interface used for redundancy. Specify shaX (X represents a number) of this component using "hanetconfig create" command with -n option.

Virtual IP address or host name(T-2)

Specify an IP address or host name to be assigned for the virtual interface. The network portion (IPv4) and a prefix (IPv6) of this IP address must be different from the IP address assigned for the physical interface. When using IPv4, use "hanetconfig create" command with -i option to specify the IP address to be allocated for the virtual interface. When using IPv6, configure these in /etc/inet/ndpd.conf file.

Subnet mask(T-3)

When using IPv4 address, specify the sub network mask value applied to the virtual IP address. If subnet is not used, this configuration can be omitted. This component is written in /etc/inet/netmasks file. However, this configuration is not necessary if using IPv6 address.

<Physical interface information>

Setup the followings for the number of physical interfaces used for redundancy.

Physical interface name(T-4,7)

Specify a name for the physical interface. This component can be set using "hanetconfig create" command with -t option (e.g. hme1, qfe2 etc).

Physical IP address or host name(T-5,8)

If using IPv4 address, specify an IP address or host name to be assigned for the physical interface. The network portion of this IP address must be different from IP address of other physical and virtual interface. To setup this component, create "/etc/hostname.physical interface name" file and then assign the IP address (or host name) in the file.
Make sure this value is different from the other IP.

Subnet mask (T-6,9)

If using IPv4 address, specify a sub network mask value applied to the physical IP address. If subnet is not used for allocation, this configuration can be omitted. This configuration is written in /etc/inet/netmasks file. Note that, this configuration is not necessary if using IPv6 address.
