<div class="body conbody"><p class="shortdesc">Before connecting the Mediatrix unit to the network, Media5 strongly recommends to
reserve an IP address in your network server – if using one – for the unit you are about to
connect. </p>
<p class="p">This way, the IP address associated with a particular unit will be known. Network servers
generally allocate a range of IP addresses for use on a network and reserve IP addresses for
specific devices using a unique identifier for each device. The Mediatrix unit unique identifier
is the media access control (MAC) address. Refer to <a class="xref" href="#task_lc1_rh3_bq">Locating the MAC Address of Your Mediatrix Unit</a>.</p>

<div class="body conbody"><p class="shortdesc">Many network switches use the Spanning Tree Protocol (STP) to manage Ethernet ports
activity.</p>
<p class="p"> STP uses a detection timeout before a router advertisement is sent to the Mediatrix unit. The
default value for this timeout is usually 30 seconds. However, when the unit wants to get an IPv6
address in Stateless autoconfiguration, this timeout is too long and the unit falls into Stateful
Autoconfiguration mode before it receives the router advertisement. This results in the unit
receiving a DHCPv6 address. To solve the issue, check if the default STP detection timeout value
in your router can be modified. If so, set it to a value of 8 s or less. If you cannot modify the
timeout value, Media5 recommends to disable the Spanning Tree Protocol on the network to which
the unit is connected.</p>

<div class="body conbody"><p class="shortdesc">There are two protocols for detecting the Ethernet link speed: parallel detection and
auto-negotiation (IEEE 802.3u). </p>
<p class="p">The auto-negotiation protocol allows the detection of the connection speed and duplex mode. It
exchanges capabilities and establishes the most efficient connection. When both endpoints support
the auto-negotiation, there are no problems. However, when only one endpoint supports
auto-negotiation, the parallel detection protocol is used. This protocol can only detect the
connection speed; the duplex mode cannot be detected. In this case, the connection may not be
established. The Mediatrix unit has the possibility to force the desired Ethernet link speed and
duplex mode by disabling the auto-negotiation and selecting the proper setting. When forcing a
link speed at one end, be sure that the other end (a hub, switch, etc.) has the same
configuration. To avoid any problem, the link speed and duplex mode of the other endpoint must be
exactly the same.</p>

<li class="li"><strong class="ph b">Configuration notes</strong>: These documents are created to facilitate the configuration of a
specific use case. They address a configuration aspect we consider that most users will need to
perform. However, in some cases, a configuration note is created after receiving a question
from a customer. They provide standard step-by-step procedures detailing the values of the
parameters to use. They provide a means of validation and present some conceptual information.
The configuration notes are specifically created to guide the user through an aspect of the

<li class="li"><strong class="ph b">User guide</strong>: The user guide explains how to customise to your needs the configuration
of the unit. Although this document is task oriented, it provides conceptual information to
help the user understand the purpose and impact of each task. The User Guide will provide
information such as where and how TR-069 can be configured in the Management Interface, how to
set firewalls, or how to use the CLI to configure parameters that are not available in the
Management Interface.</li>
<li class="li"><strong class="ph b">Reference guide</strong>: This exhaustive document has been created for advanced users. It
includes a description of all the parameters used by all the services of the Mediatrix units.
You will find, for example, scripts to configure a specific parameter, notification messages
sent by a service, or an action description used to create Rulesets. This document includes
