B.4.6 Configuring virtual interfaces with tagged VLAN (Physical IP takeover, Asynchronous switching)

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

[HOST-A]

1) Setting up the system

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

192.168.70.1    hosta1    # HOST-A Virtual IP
192.168.80.1    hosta2    # HOST-A Virtual IP
192.168.70.2    hostb1    # HOST-B Virtual IP
192.168.80.2    hostb2    # HOST-B Virtual IP
192.168.70.100  swhub1    # Switch/HUB1 IP
192.168.80.100  swhub2    # Switch/HUB2 IP

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

Note

The following setting example (/etc/sysconfig/network-scripts/ifcfg-ethX) is for RHEL5. For details, see "3.2.2 Network configuration".

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

1-4) When the system is RHEL, on the /etc/sysconfig/network file, define a statement which enables the network configuration.

NETWORKING=yes
VLAN=yes

2) Reboot

Run the following command and reboot the system. After rebooting the system, verify eth0.1 and eth1.2 is enabled using ifconfig command.

/sbin/shutdown -r now

3) Setting a subnet mask

/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 of virtual interface

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

Note

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

5) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 192.168.70.100 -b off
/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha1 -p 192.168.80.100 -b off

6) 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

7) Reboot

Run the following command and reboot the system.

/sbin/shutdown -r now

[HOST-B]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/hosts file. Defined content is same as HOST-A.

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

Note

The following setting example (/etc/sysconfig/network-scripts/ifcfg-ethX) is for RHEL5. For details, see "3.2.2 Network configuration".

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

1-4) When the system is RHEL, on the /etc/sysconfig/network file, define a statement which enables the network configuration.

NETWORKING=yes
VLAN=yes

2) Reboot

Run the following command and reboot the system. After rebooting the system, verify eth0.1 and eth1.2 is enabled using ifconfig command.

/sbin/shutdown -r now

3) Setting a subnet mask

/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 of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m e -i 192.168.70.2 -t eth0.1,eth1.1
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m e -i 192.168.80.2 -t eth1.2,eth0.2

Note

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

5) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p 192.168.70.100 -b off
/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha1 -p 192.168.80.100 -b off

6) 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

7) Reboot

Run the following command and reboot the system.

/sbin/shutdown -r now
