1. Introduction
Power over Ethernet (PoE) allows both power and data to be simultaneously carried over
standard Ethernet cables. PoE-enabled Ethernet switches can supply power directly to Ethernet
devices, thereby simplifying installation and removing the need for separate power supplies for
those devices.
The NETGEAR PROSAFE 8 Port (FS108P) and 16 Port (FS116P) switches provide 4/8 ports of
PoE and 4/8 ports without PoE. These unmanaged switches can be used to power Avaya
telephones successfully without configuration; however the switches do not support traffic
prioritization.
The NETGEAR PROSAFE™ 24 Port (FS726TP) switch supports 12 PoE ports, 12 additional
10/100Mbps ports without PoE, and 2 Gigabit/ small form-factor pluggable (SFP) ports without
PoE. The FS726TP provides effective traffic prioritization. A recommended configuration is
provided.
The generally available (GA) versions of all products were used for testing. Interoperability
testing was at the Avaya Solution and Interoperability Test Lab in Lincroft, NJ.

3. Configure the Avaya Media Server and Media Gateway
The configuration of the Avaya Media Server and Media Gateway should follow the standard
Avaya recommendations for IP Telephony [1]. In general a Quality of Service (QoS) policy
must be established across the entire IP network. The Differentiated Services (DiffServ) Code
Point (DSCP) values used by Avaya Communication Manager and by the FS726TP must be the
same.
From the System Access Terminal (SAT) enter the change ip-network-region command with
the appropriate region number specified to open an IP Network Region configuration screen. Set
the QoS DiffServ/TOS and 802.1P/Q parameters highlighted below. These are the defaults,
normally no changes will be needed.

4. Configure the NETGEAR Switches
4.1. Using the NETGEAR FS108P and FS116P
The FS108P and FS116P are unmanaged switches, therefore no configuration is necessary. The
FS108P and FS116P should be connected to the LAN by an auto-negotiation enabled uplink so
that 100Mbps Full Duplex operation can be enabled. IEEE 802.1Q tags should be stripped from
packets before the packets are sent to the FS108P or the FS116P.
With the unmanaged FS108P and FS116P switches, traffic prioritization is not supported by the
NETGEAR products. It is unlikely that the ports for the Avaya Media Server or Media Gateway
would be plugged directly into these small switches. More likely the NETGEAR switches would
be attached to the LAN and the telephones would access the Avaya Media Server and Media
Gateway over the corporate LAN. Since traffic prioritization is not supported by these switches
it is important to ensure that the connection of these switches to the corporate LAN provides
adequate quality of service.
4.2. Configure the NETGEAR FS726TP
The configuration presented here only covers the Avaya IP Telephones on the PoE ports and one
Port (26) for the uplink. The administration of the remaining ports for data applications is not
covered.

Using a Web Browser, enter the IP address of the NETGEAR FS726TP and open the NETGEAR
web interface.

Select the Power over Ethernet Configuration (POE in the left window). The default values
should be adequate, but should be verified (see Figure 4).

If the Admin Mode is not Enable, select the port and Enable PoE from the Admin pull-down
menu. Select Apply after selecting Enable.

The Class field in Figure 4 refers to the IEEE 802.3af Power Classification system (Table 2).
The FS726TP measures power at the FS726TP. The Power Limit column in Figure 4 refers to
the IEEE 802.3af Maximum Power at the power source.
Class Maximum
Power at
FS726TP
0 15.4W
1 4.0W
2 7.0W
3 15.4W
Table 2: IEEE 802.3 Power Classifications
If all of the devices are Class 2 or lower, there will be no need to assign Priority because the
total power will not exceed the Max System Power Available. If more than one of the devices
is Class 0 or Class 3, select a Priority for each port to control which ports will be shut down in
the event the powered devices exceed the Max System Power Available. In situations where a
large number of Class 0 or Class 3 devices are used, Medium priority should be assigned to one
group of the Class 0/3 devices and Low to a second group.
Figure 6: NETGEAR FS726TP PoE Priority
Assign enough Low Priority ports so that if the Max System Power Available is exceeded, the
high priority devices in the enterprise will be powered.

4.2.2. Configure the NETGEAR FS726TP Differentiated Services Values
Open the NETGEAR web interface and select Quality of Server (QoS) from the left window.
Then select DSCP from the pull down list in the right menu. The default values are to treat all
Differentiated Services (DiffServ) entries identically. Change the DiffServ entries for Call
Control (26, Assured Forwarding, AF 31 011010) and Audio (46, Expedited Forwarding EF
(101110)) to High as shown in the Figure 3 (Avaya QoS Configuration). Click Apply.
The Per Hop Behavior (PHB) Value used in on the Avaya Communications Manager (Figure 3),
is the decimal value of the DSCP entry in the NETGEAR table. The Audio PHB of 46 decimal
is 101110 binary. The Control PHB of 26 decimal is 011010 binary.
