a licensed electrician or your power company for site modifications.
•Always follow your local and national wiring rules.
Configure the Switch
Smart Managed Plus Gigabit Ethernet Switches are plug-and-play, so they can be used
without any configuration. Just connect power, connect to your network and to your
other devices, and you’re done.
For easiest access, we recommend that you cable the switch to a network with a router
or DHCP server that assigns IP addresses and power on the switch. However, it is also
possible to configure the switch connected directly only to the computer that you are
using to configure it, and not connected to the network (off-network).
You can configure and manage advanced features of the switch either by using your
computer’s web browser and accessing the switch at its IP address or by installing the
ProSAFE®Plus Utility on your Windows-based computer.
If you use a Mac or a 64-bit Windows-based computer, you can use the NETGEAR Switch
Discovery Tool to discover the switch in your network and access the local browser–based
management interface of the switch.
You can also use the NETGEAR Insight mobile app on your smartphone to discover the
switch in your network.
If your Mac supports Bonjour, you can use Bonjour to discover the switch in your network
and access the local browser interface of the switch.
For more information, see the following sections:
•Access the Switch Using a Web Browser on page 9
•Access the Switch With the ProSAFE Plus Utility on page 11
•Use the NETGEAR Switch Discovery Tool to Access the Switch on page 13

Access the Switch Using a Web Browser
This manual describes the local browser–based management interface, referred to as
the local browser interface.
You can access and configure the switch directly through its local browser interface by
entering the IP address of the switch in the address bar of a browser. When you use the
local browser interface, the simplest way to configure the switch is not connected to
your network (off-network). You can also configure the switch with it connected to your
network, router, or modem, (on-network) but you must be able to determine the IP
address of the switch if your network uses DHCP.
Access a Switch That Is Connected to a Network
By default, the DHCP client of the switch is enabled. To access the switch, use the IP
address that the DHCP server assigned to the switch.
To determine the IP address of the switch, do one of the following:
•If you use a Windows-based computer, use the ProSAFE® Plus Utility to detect the
IP address (see Access the Switch With the ProSAFE Plus Utility on page 11). You
can also access and configure the switch from the utility.
•If you use a Mac or a 64-bit Windows-based computer, use the NETGEAR Switch
Discovery Tool to detect the IP address (see Use the NETGEAR Switch Discovery
Tool to Access the Switch on page 13).
•If you use an iOS or Android smartphone, use the NETGEAR Insight mobile app to
detect the IP address (see Use the NETGEAR Insight Mobile App to Discover the
Switch on page 14).
•If you use a Mac, use Bonjour to detect the IP address (see Access the Switch From
a Mac Using Bonjour on page 15).
•Access the DHCP server.
•Use an IP scanner utility.
To use your web browser to configure a switch that is connected to a network:
1. Cable the switch to a network with a router or DHCP server that manages IP
addresses.
2. Power on the switch.
The DHCP server assigns the switch an IP address.

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.
Ports can be grouped in VLANs using 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.
•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. You can configure ports to be a part of a VLAN. When a port receives data tagged
for a VLAN, the data is discarded unless the port is a member of that VLAN. This
technique is useful for communicating with devices outside your local network as
well as receiving data from other ports that are not in the VLAN. However, for you
to be able to use an 802.1Q VLAN, you must know the VLAN ID.
Create Basic Port-Based VLANs
A port-based VLAN configuration lets you assign ports on the switch to a VLAN. The
number of VLANs is limited to the number of ports on the switch. In a basic port-based
VLAN configuration, ports with the same VLAN ID are placed into the same VLAN.
You can also assign ports to multiple VLANs (see Assign Ports to Multiple Port-Based
VLANs on page 22).
By default, all ports are members of VLAN 1.
To create basic port-based VLANs:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired network connection, or connect directly to a switch that
is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the Switch Using a Web
Browser on page 9.

Add Tagged or Untagged Ports to an
802.1Q-Based VLAN
After you define a VLAN ID using the advanced 802.1Q VLAN option (see Create
802.1Q-Based VLANs in an Advanced Configuration on page 25), you must add ports
to the VLAN.
While you add ports to a VLAN, you can specify whether the ports must be tagged or
untagged. Port tagging allows a port to be associated with a particular VLAN and allows
the VLAN ID tag to be added to data packets that are sent through the port. The tag
identifies the VLAN that must receive the data.
By default, all ports are untagged.
To add tagged or untagged ports to an 802.1Q-based VLAN:

Specify a Port PVID for an 802.1Q-Based
VLAN
A default port VLAN ID (PVID) is a VLAN ID tag that the switch assigns to data packets
it receives that are not already addressed (tagged) for a particular VLAN. For example,
if you connected a computer on port 6 and you want it to be a part of VLAN 2, configure
port 6 to automatically add a PVID of 2 to all data received from the computer. This step
ensures 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.

Enable 802.1p/DSCP-Based Quality of
Service
802.1p/DSCP-based priority uses a field in the data packet header that identifies the
class of data in the packet (for example, voice or video). When 802.1p/DSCP-based
priority is used, the switch reads information in the packet header to determine the
priority to assign to the packet. The switch reads both 802.1p tag information and
DSCP/ToS tag information. If an ingress packet contains both an 802.1p tag and a
DSCP/ToS tag, the switch gives precedence to the 802.1p tag.
All ports on the switch check the packet header and transmit the packet with a priority
determined by the packet content.
To enable 802.1p/DSCP-based QoS:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired network connection, or connect directly to a switch that

Manage Multicast Traffic With IGMP
Snooping
Internet Group Management Protocol (IGMP) snooping allows a switch to forward
multicast traffic intelligently on the switch. 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. Based on the IGMP query and report messages, the
switch forwards traffic only to the ports that request the multicast traffic. This feature
User Manual52Manage Network Settings
48-Port Gigabit Ethernet Smart Managed Plus Switch with 2 SFP Ports, Model GS750E
prevents the switch from broadcasting the traffic to all ports and possibly affecting
network performance.
The switch maintains a map that shows which links need which IP multicast streams. The
switch forwards multicast traffic only to the links that requested them and cuts multicast
traffic from links that do not contain a multicast listener. Essentially, IGMP snooping
helps optimize multicast performance at Layer 2 and is especially useful for
bandwidth-intensive IP multicast applications such as IPTV.
Customize IGMP Snooping
By default, IGMP snooping is enabled. You can customize the settings for your network.
To customize IGMP snooping:
1. Connect your computer to the same network as the switch.

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
be different from the subnet used in your network. You might see the following message
if you try to use the ProSAFE Plus Utility 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.
