Hi,
I encountered a problem when creating a VLAN interface according to the
Red_Hat_Enterprise_Linux-7-Networking_Guide. I configuered the parent
interface ifcfg-eno1 as follows:
DEVICE=eno1
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes
And I created a new file named ifcfg-eno1.5, the content is:
DEVICE=eno1.5
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.81.3
PREFIX=24
NETWORK=192.168.81.0
VLAN=yes
Then I restarted the network: systemctl restart network
After that I found that I couldn't connect to the Internet, even couldn't
ping the gateway. I thought it might be I didn't set the GATEWAY in
ifcfg-eno1.5, so I added the GATEWAY=192.168.81.254(My local area network
gateway), it didn't work.
Could anybody teach me how to create a VLAN interface in CentOS7, or tell me
what' s wrong with my configuration, more detailed more better.
Thanks
Li yulei
