B.4.5 Configuring virtual interfaces with tagged VLAN (Logical 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    hosta    # HOST-A Virtual IP
192.168.70.10   host71   # HOST-A Physical IP (Tagged VLAN interface)
192.168.80.1    hostb    # HOST-A Virtual IP
192.168.80.10   host81   # HOST-A Physical IP (Tagged VLAN interface)
192.168.70.2    hostc    # HOST-B Virtual IP
192.168.70.20   host72   # HOST-B Physical IP (Tagged VLAN interface)
192.168.80.2    hostd    # HOST-B Virtual IP
192.168.80.20   host82   # HOST-B Physical IP (Tagged VLAN interface)
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.

1-3) Describe the IP address defined in the above in the /etc/sysconfig/network-scripts/ifcfg-ethX.Y(X is 0,1. Y is 1,2) file.

2) Reflecting system setting

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 virtual interfaces

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.1 -e 192.168.70.10 -t eth0.1,eth1.1
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m d -i 192.168.80.1 -e 192.168.80.10 -t eth1.2,eth0.2

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. In RHEL8 or later, to correct mismatch of IP addresses, GLS automatically rewrites the configuration of the connection profile based on the IP address specified in the GLS command.

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.

1-3) Describe the IP address defined in the above in the /etc/sysconfig/network-scripts/ifcfg-ethX.Y(X is 0,1. Y is 1,2) file.

2) Reflecting system setting

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 virtual interfaces

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m d -i 192.168.70.2 -e 192.168.70.20 -t eth0.1,eth1.1
/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha1 -m d -i 192.168.80.2 -e 192.168.80.20 -t eth1.2,eth0.2

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. In RHEL8 or later, to correct mismatch of IP addresses, GLS automatically rewrites the configuration of the connection profile based on the IP address specified in the GLS command.

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
