Using the hostname File to Configure Groups and Test Addresses

You can use the /etc/hostname.interface files to configure multipathing groups and test addresses. To configure a multipathing group by using the /etc/hostname.interface file, you can add a line to the file by using the following syntax:

interface-address <parameters>  group group-name up \
addif logical-interface-address <parameters> up

For example, to create the group test with the following configuration:

• Physical interface hme0 with address 19.16.85.19

• A logical interface address of 19.16.85.21

• With deprecated and -failover set

• Sets the netmask and broadcast address to the default value

You add the following line to the /etc/hostname.hme0 file:

19.16.85.19 netmask + broadcast + group test up \
addif 19.16.85.21 deprecated -failover netmask + broadcast + up

For IPv6 setup, add a line to the /etc/hostname6.interface file by using the following syntax:

<parameter> group group-name up

For example, to create a test group for hme0 with an IPv6 test address, add the following line to the /etc/hostname6.hme0 file:

-failover group test up
addif 1080::56:a00:20ff:feb9:19fa up
