Configure the switch
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 by using your computer’s
web browser and accessing the switch at its IP address.
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.
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 7
•Use the NETGEAR Switch Discovery Tool to access the switch on page 9
•Access the switch from a Mac using Bonjour on page 11
Access the switch using a web browser
This manual describes how to use the local browser–based management interface,
referred to as the device UI.
You can access and configure the switch directly through its device UI by entering the
IP address of the switch in the address bar of a browser. When you access the device
UI to configure the switch, it's simpler if the switch is not connected to your network

Use VLANS for Traffic Segmentation
This chapter covers the following topics:
• VLAN overview
• Create basic port-based VLANs
• Assign ports to multiple port-based VLANs
• Create 802.1Q-based VLANs in a basic configuration
• Create 802.1Q-based VLANs in an advanced configuration

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 18).
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 7.
The login page displays.
4. Enter the switch password.

supports. If all the VLANs share an uplink to the Internet or servers, enter all in the
VLAN ID field for the port that you want to use for the uplink.
Note: If ports are members of the same LAG, you must assign them to the same
VLAN.
10. Click the Apply button.

Assign ports to multiple 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 an advanced
port-based VLAN configuration, you can assign a single port to multiple VLANs.
By default, all ports are members of VLAN 1.
