Description of each component is as follows:

<Virtual interface information>

Setup the followings for the number of virtual interfaces.

Virtual interface name (D-1)

Name a virtual interface to be configured on a physical interface used for GLS. Specify the name using "hanetconfig create" command with -n option, in "shaX" (where X is a natural number) format.

Virtual IP address or host name (D-2)

Specify an IP address or host name allocated to the virtual interface. The network portion (for IPv4) or prefix (for IPv6) of this IP address must be the same IP address assigned to the physical interface. This value is specified using "hanetconfig create" command with -i option.

Subnet mask(D-3)

When using IPv4 address, specify the value of a sub network mask used for the virtual IP address. This configuration can be omitted if not allocating a subnet. Set a subnet mask in /etc/inet/netmasks file. When using IPv6 address, it is not required to configure this value.

<Physical interface information>

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

Physical interface name (D-4,6)

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

Physical IP address or host name (D-5)

Specify an IP address or host name assigned to the physical interface. This IP address must be different from the IP address of the other physical and virtual interfaces. In order to specify an IP address for the physical interface, create "/etc/hostname. <physical interface name>" file and then assign an IP address (or host name) in the file.

<Standby patrol information>

When using Standby patrol function, setup the followings. Skip this process if Standby patrol function is not used.

Virtual interface name (D-7)

Specify a name to a virtual interface for standby patrol function. Specify it using "hanetconfig create" command with -n option, in "shaX" (where X is a natural number) format.

Automatic switch back mode (D-8)

Setting up the Standby patrol function enables the automatic switch back function when a transfer path recovers from a failure. Specify "q" to "hanetconfig create" command with -m option for using immediate switch-back after a transfer path recovery, or "p" for using standby interface capability.

Local MAC address configured in Standby interface (D-9)

If the standby patrol function is used, specify a local MAC address to be allocated to the standby interface. A local MAC address is specified in the form of: "02:XX:XX:XX:XX:XX" (where X represents a hexadecimal digit between 0 and F). The leading value "02" indicates the local MAC address, and the rest of the values can be arbitrary. However, please make sure that each MAC address should be unique within a single network. If the same MAC address is used within a network, the standby patrol may not run properly. A local MAC address is specified using "hanetconfig create" command with -a option.

<Monitored remote system information>

Setup the following for the number of virtual interfaces. This configuration cannot be omitted.

Primary Monitored remote system IP address or host name (D-10)

Specify an IP address or host name of a HUB to be monitored while primary physical interface is being used. This IP address is assigned using "hanetpoll create" command with -p option.

Secondary Monitored remote system IP address or host name (D-11)

Specify an IP address or host name of a HUB to be monitored while the secondary physical interface is being used. This IP address is specified using "hanetpoll create" command with -p option. This step can be omitted. In such case, the same value as primary remote end IP address or host name is applied.

HUB-to-HUB monitoring (D-12)

Indicate whether the HUB-to-HUB monitoring function should monitor a transfer path between cascaded HUBs or not, when two HUBs are used:

on: monitor between HUBs,
off: do not monitor between HUBs.

The default value is "off". Specify the value using "hanetpoll create"command with -b option.
