1.3 How to understand the COVERAGE LED colors
The COVERAGE LED displays quality of the network and provides important information that will provide
solutions to common questions, such as why a High Definition (HD) movie is not showing or shows with
pixels. The COVERAGE LED indicator will vary its color depending on the estimated speed of the Powerline
connection. The speed is measured in Megabits Per Second (Mbps).
Color
Information
RED
The current connection has standard quality, normal Internet
activities ex. 20Mbps are possible but the Powerline is unable to
transmit either a Standard Movie or High Definition (HD) Movie.
ORANGE
The current connection has good quality and Internet activities
ex. greater than 20Mbps and less than 40Mbps to transmit
Standard Movie and HD Movie.
GREEN
The current connection has excellent quality and Internet
activities ex. greater than 40Mbps to transmit multiple Standard
Movies and HD Movies.

1.5 Point to Multipoint Network
In the case where the PLC network is composed of three or more adapters, similar situations could arise as
with a point-to-point network.
CASE 1: The COVERAGE LED in G.hn adapter 2 and G.hn adapter 3 will show the estimated level of the
PLC link receiving from G.hn adapter 1.
CASE 2: The COVERAGE LED in G.hn adapter 1 will show the estimated level of the PLC link from which
it is receiving the most amount of traffic at any given time. For example, if G.hn adapter 1 is receiving
traffic at 50Mbps from G.hn adapter 2 and is receiving 25Mbps from G.hn adapter 3, the COVERAGE LED
will show the level with reference to the G.hn adapter 2 link, as shown in the following figure.

Chapter 3 G.hn Interface
3.1 Basic Configuration
Domain Name string of all nodes in the network.
Domain Master Node shows MAC address of domain master node of the network, The G.hn Media
Access Control is based on a time division multiple access (TDMA) architecture, in which a "domain
master" schedules Transmission Opportunities (TXOPs) that can be used by one or more devices in
the "domain".
G.hn profile of all nodes in the network: selecting which G.hn profile must be applied to the network
(PLC 50MHz, PLC 50MHz with MIMO, PLC 100MHz, COAX 100MHz and PHONE 100MHz).

12
3.2 NDIM Configuration
NDIM type set to Automatic for enabling automatic DOD selection functionality and set to Manual for
manual configuration of DOD.
Domain ID (DOD) manually set the DOD number from 1 to 15 to use a different preamble seed than
the default 0.
3.3 Encryption Configuration via WEB UI
Node security configuration: Domain Name and Encryption Configuration (Encryption Password
String) of selected node can be read and updated. There is also a label to indicate if the security keys
of the pairing process have been successfully received. Finally the pairing/unpairing order can be sent
to the node. It is the same behavior as the “Config” button.
Available Connections
In this tab table, all the available G.hn connections are presented. Remote node DID and MAC
address, transmission and reception physical speeds.

13
Chapter 4 IP Interface
4.1 IP config
In the IP configuration tab of one G.hn node, the IPv4 and IPv6 settings can be read and changed.
IPv4 subsection:
Type of IPv4 Configuration: set the G.hn node IPv4 configuration to be either DHCP or Fixed.
DHCPv4 enabled: in the case of choosing "Fixed" IP configuration in the previous option, the IPv4
Address, Subnet Mask, Default Gateway and DNS IPv4 Address should be configured; fill these fields
in. In the case of choosing DHCP they will be filled automatically when configuration is received from
the DHCP server.

14
IPv6 subsection:
DCHPv6 enabled: to enable the IPv6 DHCP configuration or choose not to.
DHCPv6 Address: to read the node's DHCPv6 address in case the DHCPv6 is enabled.
IPv6 Link Local Address: to read the node's Link Local address.
Manual IPv6 Manual Address: to configure up to four IPv6 Manual Addresses for the node.
DNSv6 Address: to configure the DNS address.

Chapter 5 Ethernet Interface
The Ethernet table shows the status & Info of the Ethernet interface; including Interface, Speed, Duplex,
Interface Type, Mode, Internal PHY & Link.
Powersaving
Ethernet powersaving can be disabled, enabled by Ethernet link or enabled by Ethernet activity; idle timer
can be configured as well.

Chapter 6 Device Interface
6.1 HW information
In this tab, basic information such as MAC Address, Serial Number, HW Product and Revision, ASIC and
Chipset of the selected node is shown. Other information about the Ethernet port is also shown.
6.2 SW information
Shows the FW version and system uptime.

17
Configuration password
The nodes in the network: to change the configuration password string from the default ("paterna") to
another; decided by the user.
Firmware update:
Current loaded firmware and API version are shown. Any flash section can be upgraded; the first flash section
should be selected and after clicking on the "OK" button the corresponding file should be chosen. Usually, a
reboot should be performed afterwards to make sure the changes are effective.
The protocol is by FTP client or TFTP client. L2 is proprietary and is reserved for future use.

Chapter 7 Multicast Interface
7.1 MCAST Configuration
In the MCAST Configuration tab of "My Network", IGMP snooping and MLD features can be enabled or
disabled. Also, IGMP multicast IP addresses ranges which the G.hn PLC network will sniff; can be configured.
Multicast Snooping Type: choose from IGMP snooping, MLD snooping or None.
IGMP/MLD broadcast report (allowed): set to NO for enabling reports dropping until the video
source is detected, this is a recommended setting when IGMP/MLD is enabled. Set to YES for
broadcasting reports until the video source is detected; this implies the multicast video stream is sent
as broadcast and it is the recommended state when IGMP/MLD is disabled.
IGMP Multicast ranges configuration: 4 multicast IP address ranges can be configured defining the
minimum and maximum IP addresses of each range. Only multicast traffic within these ranges will be
processed.

19
Chapter 8 QoS menu
8.1 QoS Configuration
In the QoS configuration tab, the packet classifier can be managed to define a QoS rule for incoming Ethernet
traffic, and assign a priority to be used in the G.hn network. Press the “Update" button for loading the newly
configured settings:
QoS CRITERION: a general criterion can be chosen among "None" (no QoS), "Custom" and
"802.1p".
Type of Frame: with this parameter the type of Ethernet traffic being transmitted by the G.hn
network should be selected. Based on this parameter, the internal offsets in the system are adjusted.
In the QoS tab, Ethernet frame offsets should be set counting number as they appear in the sniffer
SW (for instance, the same field will be in a different position if normal Ethernet frames or 802.1Q
tagged frames exist).
Packet detection 1: first packet detection rule can be configured (offset, bitmask and pattern).
Packets which accomplish it will be sent to the classification module.

20
Packet detection 2: if second packet detection is also enabled, both, first and second detection
criteria must be accomplished to pass packets to the classification module.
Packet classification: up to 8 classification rules can be defined in this section for packets which
have previously been correctly detected. For 802.1p only priorities can be managed, offset, bitmask
and pattern are predefined to sniff the PCP field.
Default priority: select default priority; which will be applied to non classified incoming packets.
Priority 7 is the highest. Priority 0 is the lowest.
