Hi，dear all：
I'm using ovs2.5.0 in centos7.2, for the reason of drivers, i has no
choice but to use function
of vlan splinters. when i set the interface 'eth0'
other_config:enable-vlan-splinters=true, and
set port br0 tag=100, then linux datapath has create the dev eth0.100, it
works.
[root@host-192-168-2-129 target]# ovs-vsctl show
26dd968c-6026-4b72-b079-e69c478afdd9
Bridge "br0"
Port "eth1"
Interface "eth1"
Port "br0"
tag: 100
Interface "br0"
type: internal
ovs_version: "2.5.0"
[root@host-192-168-2-129 target]# cat /proc/net/vlan/config
VLAN Dev name | VLAN ID
Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
eth1.100 | 100 | eth1
But when i use "ip link add ..." to create eth2.200 mannually, eth2.200
can't be created.
[root@host-192-168-2-129 target]# ip link add link eth2 name eth2.200 type
vlan id 200
[root@host-192-168-2-129 target]# cat /proc/net/vlan/config
VLAN Dev name | VLAN ID
Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
eth1.100 | 100 | eth1
and when i stop openvswitch.service and do it again, it works.
[root@host-192-168-2-129 target]# systemctl stop openvswitch
[root@host-192-168-2-129 target]# ip link add link eth2 name eth2.200 type
vlan id 200
[root@host-192-168-2-129 target]# cat /proc/net/vlan/config
VLAN Dev name | VLAN ID
Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD
eth1.100 | 100 | eth1
eth2.200 | 200 | eth2
I review the code and realize that function 'collect_splinter_vlans'
will collect all real devs
from file '/proc/net/vlan/config', and delete all vlan devs while their
real devs have no splinters
attribution, even they are not in ovs bridge.
I think this might not be suitable, eth2 is not in ovs bridge, i
should use eth2.200 to communi-
cation, but it can't be created, dose anyone can help me?
Thanks
Best regards,
Jonas
