IP address is getting changed on execution of vconfig to add a new VLAN in Red Hat Enterprise Linux

Issue

• When adding a VLAN tag to an alias interface eth1:1, the IP address of this alias interface is changed to the default value specified in the ifcfg-eth1:1 configuration file instead of the desired, manually set IP address.
• Alias/child/slave interface is offlined when adding VLAN tag to physical/parent/master interface when HOTPLUG=no is set on the alias interface.

This occurs when using either vonfig or ip link to add a VLAN tag.
