•Set up a fixed IP address for the switch on page 15.
User Manual13Install and Access the Switch in
Your Network
Gigabit Ethernet Plus Switches
Access the switch and discover the IP
address of the switch
By default, the switch receives an IP address from a DHCP server (or a router that
functions as a DHCP server) in your network.
For information about setting up a fixed (static) IP address on the switch, see Set up a
fixed IP address for the switch on page 15.
Access the switch from a Mac or Windows-based computer
using the NETGEAR Switch Discovery Tool
The NETGEAR Switch Discovery Tool (NSDT) lets you discover the switch in your network
and access the device UI of the switch from a Mac or a Windows-based computer.
To install the NSDT, discover the switch in your network, access the switch, and
discover the switch IP address:
1. Download the NSDT by visiting
netgear.com/support/product/netgear-switch-discovery-tool.aspx.
Download either the Mac or Windows version.
2. Temporarily disable the firewall, Internet security, antivirus programs, or all of these
on the computer that you will use to configure the switch.
3. Unzip the NSDT files, double-click the .exe or .dmg file (for example,
NETGEAR+Switch+Discovery+Tool+Setup+1.2.102.exe or
NetgearSDT-V1.2.102.dmg), and install the program on your computer.
Depending on your computer setup, the installation process might add the NETGEAR
Switch Discovery Tool icon to the dock of your Mac or the desktop of your
Windows-based computer.
4. Reenable the security services on your computer.
5. Power on the switch.
The DHCP server assigns the switch an IP address.
6. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection. The computer and the switch must be on
the same Layer 2 network.
7. Open the NSDT.
User Manual14Install and Access the Switch in

The right pane (or, depending on the size of your browser window, the middle pane)
shows the IP address that is assigned to the switch.
Tip: You can copy and paste the IP address into a new shortcut or bookmark it for
quick access on your computer or mobile device. However, if you restart the switch,
a dynamic IP address (assigned by a DHCP server) might change the IP address, and
the bookmark might no longer link to the login page for the switch. When you restart
the switch, you must repeat this procedure so that you can discover the new IP
address of the switch in the network and update your bookmark accordingly. You
can also set up a fixed (static) IP address for the switch (see Set up a fixed IP address
for the switch on page 15 ) to make sure that the new bookmark always links to the
login page for the switch, even after you restart the switch.
Set up a fixed IP address for the switch
By default, the switch receives an IP address from a DHCP server (or a router that
functions as a DHCP server) in your network. However, the DHCP server might not always
issue the same IP address to the switch. For easy access to the switch device UI, you can
User Manual15Install and Access the Switch in
Your Network
Gigabit Ethernet Plus Switches
set up a fixed (static) IP address on the switch. This allows you to manage the switch
anytime from a mobile device because the switch IP address remains the same.
To change the IP address of the switch, you can connect to the switch by one of the
following methods:
•Through a network connection. If the switch and your computer are connected to
the same network (which is the most likely situation), you can change the IP address
of the switch through a network connection (see Set up a fixed IP address for the
switch through a network connection on page 16).
•Through a direct connection. In the unlikely situation that the switch is not connected
to a network, or for some reason you cannot connect to the switch over a network
connection, you can change the IP address of the switch by using an Ethernet cable
and making a direct connection to the switch (see Set up a fixed IP address for the
switch by connecting directly to the switch off-network on page 17).
Set up a fixed IP address for the switch through a network
connection
If the switch and your computer are connected to the same network (which is the most
the likely situation), you can change the IP address of the switch through a network
connection.
To disable the DHCP client of the switch and change the IP address of the switch
to a fixed IP address by using a network connection:
1. Open a web browser from a computer that is connected to the same network as the
switch.
2. Enter the IP address that is assigned to the switch.
The login page displays.
3. Enter the switch password.
The default password is password. The password is case-sensitive.
The HOME page displays.
The right pane (or, depending on the size of your browser window, the middle pane)
shows the IP address that is assigned to the switch.

Set the quality of service mode and port rate
limits
You can manually set the Quality of Service (QoS) modes to manage traffic:
•Port-based QoS mode. Lets you set the priority (low, medium, high, or critical) for
individual port numbers and lets you set rate limits for incoming and outgoing traffic
for individual ports. If broadcast filtering is enabled, you can also set the storm control
rate for incoming traffic for individual ports.
•802.1P/DSCP QoS mode. Applies pass-through prioritization that is based on
tagged packets and lets you set rate limits for incoming and outgoing traffic for
individual ports. If broadcast filtering is enabled, you can also set the storm control
rate for incoming traffic for individual ports.
This QoS mode applies only to devices that support 802.1P and Differentiated
Services Code Point (DSCP) tagging. For devices that do not support 802.1P and
DSCP tagging, ports are not prioritized but the configured rate limit is still applied.
You can limit the rate of incoming traffic, outgoing traffic, or both on a port to prevent
the port (and the device that is attached to it) from taking up too much bandwidth on
the switch. Rate limiting, which you can set for individual ports in either QoS mode,
simply means that the switch slows down all traffic on a port so that traffic does not
exceed the limit that you set for that port. If you set the rate limit on a port too low, you
might, for example, see degraded video stream quality, sluggish response times during
online activity, and other problems.
Use port-based quality of service and set port priorities
802.1P/DSCP is the default QoS mode on the switch, but you can also set port-based
QoS.
For each port, you can set the priority and the rate limits for both incoming and outgoing
traffic:
•Port priority. The switch services traffic from ports with a critical priority before traffic
from ports with a high, medium, or low priority. Similarly, the switch services traffic
from ports with a high priority before traffic from ports with a medium or low priority.
If severe network congestion occurs, the switch might drop packets with a low priority.
•Port rate limits. The switch accepts traffic on a port at the rate (the speed of the
data transfer) that you set for incoming traffic on that port. The switch transmits traffic
from a port at the rate that you set for outgoing traffic on that port. You can select
each rate limit as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

Use 802.1P/DSCP quality of service
In the 802.1P/DSCP QoS mode, the switch uses the 802.1P or DSCP information in the
header of an incoming packet to prioritize the packet. With this type of QoS, you cannot
control the port prioritization on the switch because the device that sends the traffic
(that is, the packets) to the switch prioritizes the traffic. However, you can set the rate
limits for individual ports on the switch.
The switch accepts traffic on a port at the rate (the speed of the data transfer) that you
set for incoming traffic on that port. The switch transmits traffic from a port at the rate
that you set for outgoing traffic on that port. You can select each rate limit as a predefined
data transfer threshold from 512 Kbps to 512 Mbps.

limits
A broadcast storm is a massive transmission of broadcast packets that are forwarded
to every port on the switch. If they are not blocked, broadcast storm packets can delay
or halt the transmission of other data and cause problems. However, you can block
broadcast storms on the switch.
You can also set storm control rate limits for each port. Storm control measures the
incoming broadcast, multicast, and unknown unicast frame rates separately on each
port, and discards the frames if the rate that you set for the port is exceeded. By default,
no storm control rate limit is set for a port. You can select each storm control rate limit
as a predefined data transfer threshold from 512 Kbps to 512 Mbps.

Use VLANS for Traffic Segmentation
This chapter describes how you can use VLANs to segment traffic on the switch.
The chapter contains the following sections:
• VLAN overview
• Activate the Basic Port-Based VLAN mode and assign VLANs
• Manage advanced port-based VLANs
• Manage basic 802.1Q VLANs
• Manage advanced 802.1Q VLANs
• Deactivate a port-based or 802.1Q VLAN mode and delete all VLANs

VLAN overview
Virtual LANs (VLANs) are made up of networked devices that are grouped logically into
separate networks. You can group ports on a switch to create a virtual network made
up of the devices connected to the ports.
You can group ports in VLANs using either port-based or 802.1Q criteria:
•Port-based VLANs. Assign ports to virtual networks. Ports with the same VLAN ID
are placed in the same VLAN. This feature provides an easy way to partition a network
into private subnetworks.
If the switch is the only switch in your network and you do not need a VLAN to function
across multiple network devices (such as a router, another switch, a WiFi AP, or any
network device that supports VLANs), we recommend that you use a port-based
VLAN. If you need a single VLAN on a single port (other than the uplink port), use
the basic port-based VLAN configuration. If you need multiple VLANs on a single
port, use the advanced port-based VLAN configuration.
The switch supports the following port-based VLAN modes:
-Basic Port-Based VLAN. In a basic port-based VLAN configuration, ports with
the same VLAN ID are placed into the same VLAN. Except for the uplink port,
you can assign each port to a single VLAN only. The number of VLANs is limited
to the number of ports on the switch.
-Advanced Port-Based VLAN. In an advanced port-based VLAN configuration,
ports with the same VLAN ID are also placed into the same VLAN, but you can
assign a single port to multiple VLANs.
•802.1Q VLANs. Create virtual networks using the IEEE 802.1Q standard. 802.1Q
uses a VLAN tagging system to determine which VLAN an Ethernet frame belongs
to. To use an 802.1Q VLAN that is set up on another device, you must know the
VLAN ID.
If you need a VLAN to function across multiple network devices (such as a router,
another switch, a WiFi AP, or any network device that supports VLANs), we
recommend that you use an 802.1Q VLAN. If you do not need to customize tagging
on a single port and you do not need a voice VLAN, use the basic 802.1Q VLAN
configuration. If you do need to customize tagging on a single port or you do need
a voice VLAN, use the advanced 802.1Q VLAN configuration.
The switch supports the following 802.1Q VLAN modes:
-Basic 802.1Q VLAN. In a basic 802.1Q VLAN configuration, VLAN 1 is added to
the switch and all ports (1 through 5 for the GS305EP or GS305EPP, and 1 through
8 for the GS308EP or GS308EPP) function in access mode as members of VLAN
1. You can change the mode for a port to trunk mode, you can add more VLANs,
and you can assign a different VLAN to a port. A port that functions in access

Segmentation
Gigabit Ethernet Plus Switches
mode can belong to a single VLAN only and does not tag the traffic that it
processes. A port that functions in trunk mode automatically belongs to all VLANs
on the switch and tags the traffic that it processes.
-Advanced 802.1Q VLAN. In an advanced 802.1Q VLAN configuration, VLAN 1
is added to the switch and all ports (1 through 5 for the GS305EP or GS305EPP,
and 1 through 8 for the GS308EP or GS308EPP) are untagged members of
VLAN 1. You can tag ports, untag ports, exclude ports, add more VLANs, assign
a different VLAN to a port, manage port PVIDs, and manage a voice VLAN.

Assign the port mode in a basic 802.1Q VLAN configuration
In an 802.1Q VLAN configuration, you can assign one of the following port modes:
•Access mode. A port that functions in access mode can belong to a single VLAN
only and does not tag the traffic that it processes. You would typically use access
mode for a port that is connected to an end device such as a gaming device, media
device, or computer. When a port that functions in access mode receives data that
is untagged, the data is delivered normally. When a port that functions in access
mode receives data that is tagged for a VLAN other than the one the port belongs
to, the data is discarded.
•Trunk mode. A port that functions in trunk mode automatically belongs to all VLANs
on the switch and tags the traffic that it processes. You would typically use trunk
mode for a port that is connected to another network device. For example, you
would assign trunk mode for an uplink to another switch or router and for a downlink
to a WiFi access point.

you connect a computer to port 6 of the switch and you want it to be a part of VLAN 2,
add port 6 as a member of VLAN 2 and set the PVID of port 6 to 2. This configuration
automatically adds a PVID of 2 to all data that the switch receives from the computer
and makes sure that the data from the computer on port 6 can be seen only by other
members of VLAN 2. You can assign only one PVID to a port.
Note: If you did not yet create an advanced 802.1Q VLAN, all ports are assigned PVID 1

Set an existing advanced 802.1Q VLAN as the voice VLAN
and adjust the CoS value
The switch can support a single advanced 802.1Q VLAN as the voice VLAN to facilitate
voice over IP (VoIP) traffic. Because a voice VLAN might require a single port to join to
multiple VLANs as an untagged member, you can set up a voice VLAN only as an
advanced 802.1Q VLAN. For information about creating an advanced 802.1Q VLAN,
see Create an advanced 802.1Q VLAN on page 48.
A port that is a member of the voice VLAN sends all its voice packets through the voice
VLAN but other types of packets (for example, data packets) that come in on the port
are forwarding according to the PVID setting on the port.
The default Class of Service (CoS) value for the voice VLAN is 6, which you can adjust
to any value from 0 (the lowest priority) to 7 (the highest priority). The voice VLAN CoS
value applies to all traffic on the voice VLAN. You can set the default VLAN (VLAN 1) as

Manage the Switch in Your Network
This chapter describes how you can manage the switch in your network.
The chapter contains the following sections:
• Manage NETGEAR Switch Discovery Protocol
• Set up static link aggregation
• Manage multicast
• Change the IP address of the switch
• Reenable the DHCP client of the switch
57
Manage NETGEAR Switch Discovery Protocol
A NETGEAR device or application that supports NETGEAR Switch Discovery Protocol
(NSDP) can discover the switch in the network so that you can find the switch IP address
and log in to the device UI of the switch. NSDP is enabled by default. You can disable
NSDP for security reasons.
To manage NSDP:
1. Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.

Set up static link aggregation
Static link aggregation on the switch allows you to combine multiple Ethernet ports into
a single logical link. Your network devices treat the aggregation as if it were a single
link. Depending on how link aggregation is set up in your network, the link supports
either increased bandwidth (a larger pipe) or fault tolerance (if one port fails, another
one takes over).
The GS305EP and GS305EPP switches each support a single static link aggregation
group (LAG) with up to four ports.
The GS308EP and GS308EPP switches each support two static LAGs with up to four
ports each. That means that one static LAG can support a link of up to 4 Gbps.
User Manual58Manage the Switch in Your
Network
Gigabit Ethernet Plus Switches
Note: The switch does not support Link Aggregation Control Protocol (LACP).
You set up static link aggregation on the switch through a LAG in the following order:
1. Set up the LAG on the switch (see Set up a link aggregation group on page 59).
2. Connect the ports that must be members of the LAG on the switch to the ports that
must be members of the LAG on another device in your network (see Make a link
aggregation connection on page 60).
3. Enable the LAG on the switch (see Enable a link aggregation group on page 60) and
on the other device.
Set up a link aggregation group
You set up static link aggregation on the switch by adding ports to a link aggregation
group (LAG), and by enabling the LAG. However, for a LAG to take effect, you first must
make sure that all ports that participate in the LAG (that is, the ports on both devices)
use the same speed, duplex mode, and flow control setting (see Manage individual
port settings on page 26 for information about changing these settings on the switch),
and you must set up a physical link aggregation connection (see Make a link aggregation
connection on page 60).
After you set up a link aggregation group and make a physical link aggregation
connection, you can enable the link aggregation group (see Enable a link aggregation
group on page 60).
To set up one or more link aggregation groups on the switch:
1. Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.
3. Enter the device management password.
The password is the one that you specified the first time that you logged in. The
password is case-sensitive.

A LAG must consist of at least two ports, but can consist of all ports.
The number of LAGs that the switch supports depends on the model.
7. Click the APPLY button.
Your settings are saved.
Make a link aggregation connection
Before you make a physical link aggregation connection to another network device
(usually a router or another switch) that also supports link aggregation, you must first
set up a LAG on the switch (see Set up a link aggregation group on page 59). If you do
not, the LAG cannot take effect. Whether a LAG on the switch functions to support
increased bandwidth or fault tolerance depends on the LAG configuration on the other
network device.
All ports that participate in a LAG (that is, the ports on both devices) must use the same
speed, full duplex mode, and flow control setting. For information about changing these
settings on the switch, see Manage individual port settings on page 26.
To make link aggregation connections between the switch and another network
device:
Using Ethernet cables, connect each port that must be a member of the LAG on the
switch to each port that must be a member of the same LAG on another network
device.
The port numbers on the other network device do not matter as long as:
•The ports on the other network device are members of the same LAG.
•The LAG consists of the same total number of ports.
•The ports use the same speed, full duplex mode, and flow control setting as the
ports in the LAG on the switch.
Enable a link aggregation group
After you set up a link aggregation group (see Set up a link aggregation group on page
59) and make a physical link aggregation connection (see Make a link aggregation
connection on page 60), you can enable the link aggregation group.
Note: You must also enable the LAG on the other network device.

Manage multicast
Multicast IP traffic is traffic that is destined to a host group. Host groups are identified
by Class D IP addresses, which range from 224.0.0.0 to 239.255.255.255.
Internet Group Management Protocol (IGMP) snooping allows the switch to forward
multicast traffic intelligently. Based on the IGMP query and report messages, the switch
forwards traffic only to the ports that request multicast traffic, rather than to all ports,
which could affect network performance.
IGMP snooping helps to optimize multicast performance and is especially useful for
bandwidth-intensive IP multicast applications such as online media streaming
applications.

Manage the power saving mode
The power saving mode enables the IEEE 802.3az Energy Efficient Ethernet (EEE)
function, cable length power saving, and link-up and link-down power saving:
•IEEE 802.3az. Combines the Energy Efficient Ethernet (EEE) 802.3 MAC sublayer
with the 100BASE-TX, 1000BASE-T, and 10GBASE-T physical layers to support
operation in Low Power Idle (LPI) mode. When LPI mode is enabled, systems on
both sides of the link can disable portions of their functionality and save power during
periods of low link utilization.
•Short cable power saving. Dynamically detects and adjusts power that is required
for the detected cable length.
•Link-down power saving. Reduces the power consumption considerably when the
network cable is disconnected. When the network cable is reconnected, the switch
detects an incoming signal and restores normal power.

PoE considerations for switches that support
PoE
A switch that supports Power over Ethernet (PoE) prioritizes the PoE power that it supplies
in ascending port order (that is, from the lowest-numbered port to the highest-numbered
port), up to its total power budget. If the power requirements for the attached powered
devices (PDs) exceed the total power budget of the switch, the PD on the
highest-numbered port is disabled to make sure that the PDs that are connected to the
higher-priority, lower numbered ports are supported first.
Just because a PD is listed as an 802.3at PoE powered device does not necessarily mean
that it requires the maximum power limit of the specification. Many PDs require less
power, allowing all PoE ports to be active simultaneously.
The following table describes the PoE classes and the PoE power that a switch allocates.

5. To enable or disable the uninterrupted PoE feature, click the Uninterrupted POE
button:
•Disabled: The button bar displays gray and the button is positioned on the left.
•Enabled: The button bar displays green and the button is positioned on the right.
By default, the uninterrupted PoE feature is disabled, causing the switch to stop
providing PoE power while it is rebooting. If you enable the uninterrupted PoE
feature, the switch continues to provide PoE power to any attached PDs while the
switch is rebooting, even if it is rebooting after a regular firmware update.
However, note the following situations during which the switch temporarily stops
providing PoE:
•The switch reboots because you reset it to factory default settings.
•The switch reboots because you upgrade the switch firmware with a change in
the configuration structure, an update to the chip driver, or a change to the default
PoE settings.
6. On the SETTING menu, open the menu for the port number.
The port settings display.
7. Click the EDIT button.
8. From the Port Power menu, select one of the following options:
•Enable: The port’s capacity to deliver power is enabled. This is the default setting.
•Disable: The port’s capacity to deliver power is disabled.
9. From the Port Priority menu, select the priority for the port in relation to other ports
if the total power that the switch is capable of delivering exceeds the total power
budget:
•Low: Low priority. This is the default setting.
•High: High priority.
•Critical: Critical priority.
User Manual81Maintain and Monitor the Switch
Gigabit Ethernet Plus Switches
The port priority determines which ports can still deliver power after the total power
delivered by the switch exceeds the total power budget. (In such a situation, the
switch might not be able to deliver power to all connected devices.) If the same
priority applies to two ports, the lower-numbered port receives higher priority.
10. From the Power Mode menu, select the PoE mode in which the port must function:
•802.3af: The port is powered in and limited to the IEEE 802.3af mode. A PD that
requires IEEE 802.3at does not receive power if the port functions in IEEE 802.3af
mode.
•Legacy: The port is powered using high-inrush current, which is used by legacy
PDs that require more than 15W to power up.
•Pre-802.3at: The port is initially powered in the IEEE 802.3af mode and, before
75 msec pass, is switched to the high power IEEE 802.3at mode. Select this mode
if the PD does not perform Layer 2 classification or if the switch performs 2-event
Layer 1 classification.
•802.3at: The port is powered in the IEEE 802.3at mode and is backward
compatible with IEEE 802.3af. The 802.3at mode is the default mode. In this
mode, if the switch detects that the attached PD requests more power than IEEE
802.3af but is not an IEEE 802.3at Class 4 device, the PD does not receive power
from the switch.
11. From the Power Limit Type menu, select one of the following options:
•None: The port draws up to Class 0 maximum power in low power mode and
up to Class 4 maximum power in high power mode.
•Class: The port power limit is equal to the class of the attached PD.
•User: The port power limit is equal to the value that is specified in the Power
Limit (W) field. This is the default setting.
Note: If a PD doesn't report its class correctly, these options can preserve PoE power
by preventing the switch from delivering more power than the PD requires. However,
depending on which option you select, a PD that doesn't report its class correctly
might now power up at all.
Note: Power Limit (W) displays a fixed power of 31.2 Watts, and you cannot change
it.

Resolve a subnet conflict to access the switch
If you power on the switch before you connect it to a network that includes a DHCP
server, the switch uses its own default IP address of 192.168.0.239. This subnet might
User Manual87Diagnostics and
Troubleshooting
Gigabit Ethernet Plus Switches
be different from the subnet used in your network. You might see the following message
if you try to access the switch:
The switch and manager IP address are not in the same subnet.
To resolve this subnet conflict:
1. Disconnect the Ethernet cable between the switch and your network.
2. Shut down power to the switch.
3. Reconnect the Ethernet cable between the switch and your network.
4. Reapply power to the switch.
The switch powers on. The network DHCP server discovers the switch and assigns
it an IP address that is in the correct subnet for the network.
PoE troubleshooting suggestions
Here are some tips for correcting Power over Ethernet (PoE) problems that might occur
on switches that support PoE:
•Make sure that the PoE Max LED is off. If the PoE Max LED is solid amber, disconnect
one or more PoE devices to prevent PoE oversubscription.
•Make sure that the Ethernet cables are plugged in correctly. For each powered
device (PD) that is connected to the switch, the associated PoE port LED on the switch
lights solid green. If the associated PoE port LED lights solid amber, a PoE fault
occurred and PoE halted because of one of the conditions listed in the following
table.
Table 6. PoE fault conditions and possible solutions
Possible SolutionPoE Fault Condition
The problem is most likely with the
attached PD. Check the condition
of the PD or restart the PD by
disconnecting and reconnecting
the PD.
A PoE-related short circuit occurred on the port.
The PoE power demand of the PD exceeded the maximum level that the
switch permits. The maximum level is 15.4W for a PoE connection or
30W for a PoE+ connection.
The PoE current on the port exceeded the classification limit of the PD.
Restart the switch to see if the
condition resolves itself.
The PoE voltage of the port is outside the range that the switch permits.
