chenxing b6a0fa8a76 import the admin guide content from openstack-manuals 
Neutron repository has the networking guide in admin/,
so we cannot just import the admin guide contents into admin/
as it potentially breaks the existing document structure of
the networking guide. This commit imports the admin guide
into admin/archives directory so that the team can migrate them
into the networking guide after careful reviews.

Advanced configuration options

This section describes advanced configuration options for various system components. For example, configuration options where the default works but that the user wants to customize options. After installing from packages, $NEUTRON_CONF_DIR is /etc/neutron.

L3 metering agent

You can run an L3 metering agent that enables layer-3 traffic metering. In general, you should launch the metering agent on all nodes that run the L3 agent:

$ neutron-metering-agent --config-file NEUTRON_CONFIG_FILE \
  --config-file L3_METERING_CONFIG_FILE

You must configure a driver that matches the plug-in that runs on the service. The driver adds metering to the routing interface.

Option Value
Open vSwitch
interface_driver ($NEUTRON_CONF_DIR/metering_agent.ini) openvswitch
Linux Bridge
interface_driver ($NEUTRON_CONF_DIR/metering_agent.ini) linuxbridge

L3 metering driver

You must configure any driver that implements the metering abstraction. Currently the only available implementation uses iptables for metering.

driver = iptables

L3 metering service driver

To enable L3 metering, you must set the following option in the neutron.conf file on the host that runs neutron-server:

service_plugins = metering
