Virtual interfaces in Virtual NIC mode are activated or deactivated in conjunction with the network service of the operating system in the same manner as normal physical NICs. Therefore, you need to define settings for IP addresses or subnet masks in the interface setting file (/etc/sysconfig/network-scripts/ifcfg-shaX).
Confirmation method
Check that the IP addresses or subnet masks are defined in the interface setting file (/etc/sysconfig/network-scripts/ifcfg-shaX) for the virtual interface.
# cat /etc/sysconfig/network-scripts/ifcfg-sha0 DEVICE=sha0 IPADDR=192.168.1.1 |
