B.6.3 Configuring virtual interfaces with tagged VLAN (Logical IP takeover, Synchronous switching)

This section describes an example configuration procedure of the network shown in the diagram below.

The xx and yy in the figure below are assigned automatically by the automatic address configuration.

For the network configuration other than GLS, refer to "3.2.2 Network configuration".

[HOST-A]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/hosts file.

192.168.70.1    hosta    # HOST-A Virtual IP
192.168.70.3    host71   # HOST-A Physical IP (Tagged VLAN interface)
192.168.80.1    hostb    # HOST-A Virtual IP
192.168.80.3    host81   # HOST-A Physical IP (Tagged VLAN interface)
192.168.70.2    hostc    # HOST-B Virtual IP
192.168.70.4    host72   # HOST-B Physical IP (Tagged VLAN interface)
192.168.80.2    hostd    # HOST-B Virtual IP
192.168.80.4    host82   # HOST-B Physical IP (Tagged VLAN interface)
192.168.70.100  swhub1   # Primary Switch/HUB IP
192.168.70.101  swhub2   # Secondary Switch/HUB IP
fec0:1::1       v6hosta1 # HOST-A Virtual IP (1)
fec0:2::1       v6hosta2 # HOST-A Virtual IP (2)
fec0:1::2       v6hostb1 # HOST-B Virtual IP (1)
fec0:2::2       v6hostb2 # HOST-B Virtual IP (2)

1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.

Contents of /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
BOOTPROTO=static
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

1-3) Configure /etc/sysconfig/network-scripts/ifcfg-ethX.Y (X is 0,1. Y is 1,2) file as follows.

Contents of /etc/sysconfig/network-scripts/ifcfg-eth0.1

DEVICE=eth0.1
BOOTPROTO=static
IPADDR=192.168.70.3
NETMASK=255.255.255.0
ONBOOT=yes
VLAN=yes

Contents of /etc/sysconfig/network-scripts/ifcfg-eth0.2

DEVICE=eth0.2
BOOTPROTO=static
IPADDR=192.168.80.3
NETMASK=255.255.255.0
ONBOOT=yes
VLAN=yes

Contents of /etc/sysconfig/network-scripts/ifcfg-eth1.1
DEVICE=eth1.1 BOOTPROTO=static ONBOOT=yes VLAN=yes
Contents of /etc/sysconfig/network-scripts/ifcfg-eth1.2
DEVICE=eth1.2 BOOTPROTO=static ONBOOT=yes VLAN=yes

2) Reflecting system setting

Run the following command and reboot the system. After rebooting the system, verify eth0.1 and eth0.2 are enabled using the ip command.

/sbin/shutdown -r now

3) Setting subnet masks

/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.70.0 -m 255.255.255.0
/opt/FJSVhanet/usr/sbin/hanetmask create -i 192.168.80.0 -m 255.255.255.0

4) Creating IPv4 virtual interfaces

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.1 -e 192.168.70.3 -t eth0.1,eth1.1
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m d -i 192.168.80.1 -e 192.168.80.3 -t eth0.2,eth1.2

Note

Ensure that the physical IP address specified using option '-e' is the same IP address configured in /etc/sysconfig/network-scripts/ifcfg-ethX.Y.

5) Creating IPv6 virtual interfaces

/opt/FJSVhanet/usr/sbin/hanetconfig copy inet6 -n sha0,sha0 -i fec0:1::1/64
/opt/FJSVhanet/usr/sbin/hanetconfig copy inet6 -n sha1,sha1 -i fec0:2::1/64

6) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 192.168.70.100,192.168.70.101 -b off

7) Setting up the HUB monitoring function (Synchronous switching)

/opt/FJSVhanet/usr/sbin/hanetpoll copy -n sha0,sha1

8) Setting up the Standby patrol monitoring function

Please define only one Standby patrol monitoring function.

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha2 -m p -t sha0

9) Reboot

Run the following command and reboot the system.

/sbin/shutdown -r now
