[CentOS] 答复: 答复: How to configure VLAN in CentOS7

[liyulei]

Thank you again.

I am deploying Liberty Neutron, according the official document, there are
two NIC at least, but my physical machine has only one. Someone suggested me
I could create a vlan interface, then everything would be ok. Until now,
though I created the vlan interface, it can't attach to the Internet. 

Could other methods created virtual interface instead of vlan interface?

Thanks

My guess would be that the switch isn't configured to give you access to
VLAN 5 with tagged packets.  In that case, there's no need for you to
configure eno1.5

Specifically what are you trying to accomplish by configuring a tagged VLAN
interface?
