Do I need to assign the parent interface when using VLAN?
-
Hi everyone,
I have used VLAN for some days and I am learning the basic knowledge about Networking.
In my searching about VLAN, I found that I should not mix untagged and tagged VLAN. Then I started to change the untagged Interface to a tagged Interface.
Currently my Network is configured liked this:
And I have changed it to:
However, I found that if I changed the Network Interface from Parent Interface
mlxen1
to tagged VLANmlxen1.50
. I can still use the Network without assign the parent Interfacemlxen1
. Do I need to assign the parent Interface mxlan1, or just leave it unassigned?Besides, I would like to know why I can mix untag and tagged VLAN in my previous setting.
Thank you.
