Pid - lf / var / lib / dhclient / dhclient - vlcp - port1. Vlcp-docker-plugin also uses this to generate MTUconfigurations for docker.You may use an extra parameter vni=10001 to explictly specify the VNI used by this logical network.If ommited, VLCP automatically assign a free VNI from the physical network VNI ranges. If your underlay network supports larger MTU, you can set a larger MTU instead.The embedded DHCP service uses this configuration to generate a DHCP Option to set MTU on thelogical port (vNIC in a virtual machine). NoteVXLAN introduces extra overlay packet header into the packet, so we leave 50 bytes for the headerand set MTU=1450.

When a string parameter is quoted by ``, VLCP recognizes it as a literal expression in Python.You may use numbers, string, tuples, list, dictionary, sets and any combinations of them in a quoted expression.‘’ have special meanings in curl, that is way we use -g option to turn it off. Some APIs need data types other than strings for itsparameters. Though use the HTTP GET/POST format is usually the easiest way tocall the API in Shell command-line, when integrating with other systems JSON-format POST may be moreconvient.`` quoted expression is a VLCP-specified extension. Generally, unix domain sockets are more light-weight with less overhead than IP sockets, so they can provide faster communication between controller and bridge. If you are only using the controller on the local machine, you can set the controller to use a unix domain sockets. NoteThe 'ptcp:' option is set to match how the controller is setup in /etc/conf.d/ovs-controller, which by default is configured to listen to IP socket connections on port 6633.

Or it can be turned off with the controller functionality provided by a controller elsewhere in the network.For the scope of this article, we will just assume that the controller daemon is only being used by the single virtual switch we are creating.System Setup KernelYou need to activate the following kernel options. The controller daemon provides this functionality and can control multiple Open vSwitchers, as well as hardware switchers support OpenFlow.

This also blurs the distinction between the roles of switcher and router. This provides the advantages of quicker deployment, cheaper hardware, and tight integration of both physical and virtual switchers.
