Hi Ben,
Thanks for this info, but I already know that ...
My problem is that, Every time when system reboot then i use the command
like:
vs-vsctl set interface eth0 other-config:enable-vlan-splinters=true
I want to integrate this command into network scripts
files(/etc/sysconfig/network-scripts/ifcfg-*)
Just like, I have network configuration like below:
[root@linux]# ovs-vsctl show
f95289de-40e2-4bf5-9f07-
3c8300e296db
Bridge "ovsbr0"
Port "eth0"
Interface "eth0"
Port "ovsbr0"
Interface "ovsbr0"
type: internal
Port "ovsbr0.4093"
tag: 4093
Interface "ovsbr0.4093"
type: internal
ovs_version: "1.4.6"
[root@linux]# lsmod | grep openvswitch
openvswitch 37890 1
So how to integrate VLAN splinters command into network scripts file here ?
Thanks
