L4 plugin

The l4plugin is a Core Agent Plugin that is designed to configure VPP application namespaces. Configuration managed by this plugin is modelled by the proto file. The configuration must be stored in etcd using the following key:

/vnf-agent/<agent-label>/vpp/config/v1/l4/namespaces/<namespaceID>

/vnf-agent/<agent-label>/vpp/config/v1/l4/features/feature

An example of configuration in json format can be found here.

Note: the l4 features need to be enabled on the VPP. To do so, use second json configuration file which can be found here here

To insert config into etcd in json format vpp-agent-ctl can be used. We assume that we want to configure vpp with label vpp1 and config is stored in the app-ns.json file. At first, enable L4 features, then configure the application namespace.

vpp-agent-ctl -put "/vnf-agent/vpp1/vpp/config/v1/l4/features/feature" json/enable-l4.json
vpp-agent-ctl -put "/vnf-agent/vpp1/vpp/config/v1/l4/namespaces/ns1" json/app-ns.json

The vpp-agent-ctl contains a simple predefined application namespace config also. It can be used for testing purposes. To enable l4 features, run:

vpp-agent-ctl -el4

To disable it:

vpp-agent-ctl -dl4

To configure application namespace:

vpp-agent-ctl -appns

Note: application namespaces cannot be removed. Currently it is not supported by the VPP.
