+===== Configuration tips =====
+==== Configuration in Debian/Ubuntu via /etc/network/interfaces ====
+Example:
+<code|/etc/network/interfaces>
+allow-ovs br0
+iface br0 inet manual
+   ovs_type OVSBridge
+   ovs_ports mgt0 eth1 eth2
+   ovs_extra set Bridge br0 stp_enable=true
+allow-br0 mgt0
+iface mgt0 inet static
+    address 10.14.131.34
+    netmask 255.255.255.224
+    ovs_bridge br0
+    ovs_type OVSIntPort
+    ovs_options vlan_mode=access
+    ovs_options tag=999
+allow-br0 eth1
+iface eth1 inet manual
+    ovs_bridge br0
+    ovs_type OVSPort
+    ovs_options vlan_mode=native-untagged
+    ovs_options trunks=10,20,30,40
+    ovs_options tag=999
+allow-br0 eth2
+iface eth2 inet manual
+    ovs_bridge br0
+    ovs_type OVSPort
+    ovs_options vlan_mode=trunk
+    ovs_options trunks=30,40
+</code>
+==== Creating GRE tunnel ====
+<code|/etc/network/interfaces>
+allow-ovs br0
+iface br0 inet manual
+   ovs_type OVSBridge
+   ovs_ports mgt0 eth1
+   ovs_extra set Bridge br0 stp_enable=true
+   post-up ovs-vsctl add-port br0 vgre0 -- set interface vgre0 type=gre \
+	 options:remote_ip=10.0.0.1
+....
+</code>
+===== Frequently use (useful) command =====
+# Dump flows
+   ovs-ofctl dump-flows br0
+# Show mac table
+   ovs-appctl fdb/show br0
+# Show switch
+   ovs-vsctl show
+# Show datapath
+   ovs-dpctl show
+# Turn debugging on
+   ovs-appctl vlog/set dbg
+===== Troubleshooting =====
+==== GRE problem ====
+"You need to unload ''**ip_gre**'' and ''**gre**'' module, openvswitch GRE does not work along with kernel GRE module for now."
