AV local browser UI overview
Your switch contains an embedded web server and management software for managing
and monitoring the switch. The switch functions as a simple switch without the
management software. However, you can use the management software to configure
many advanced features that can improve AV flows, switch efficiency, and overall network
performance.
The switch software includes a set of comprehensive management features for
configuring and monitoring the switch through one of the following methods:
•Audio-video local browser user interface (AV UI), either over an Ethernet network
port or over the out-of-band (OOB) port (also referred to as the service port).
•Main local browser user interface (main UI), either over an Ethernet network port or
over the OOB port.
•Simple Network Management Protocol (SNMP)
•Command-line interface (CLI)
Audio Video User Manual8Getting Started with the AV UI
AV Line of Fully Managed Switches M4250 Series
Each of the standards-based management methods allows you to configure and monitor
the components of the switch. The method you use to manage the system depends on
your network size and requirements, and on your preference.
This manual describes how to use the audio-video (AV) local browser user interface (UI)
to manage and monitor the switch. We abbreviate the audio-video local browser UI as
the AV UI.
The AV UI is a web-based management tool that lets you configure and manage
audio-video and other types of network profiles remotely using a standard web browser.
Note: To configure all available switch features, including VLANs, QoS, and ACLs, use
the main UI.
Use a web browser to log in to the AV UI
If this is the first time that you log in to the switch and you must use the default IP address
of the switch, see the information in the installation guide. You can use a web browser
to access the switch and log in. You must be able to ping the IP address of the
management interface or out-of-band (OOB) port from your computer for web access
to be available.
Note: The first time that you log in as an admin user to either the AV UI or the main UI,
no password is required (that is, the password is blank). After you log in for the first time,
you are required to specify a local device password that you must use each subsequent
time that you log in to either the AV UI or the main UI. (Using the main UI, you can change
the password again.)
Log in to the AV UI using the switch default IP address
To use the switch default IP address to access the switch over the AV UI:
1. Prepare your computer with a static IP address:
•Ethernet network port: For access over an Ethernet network port, use a static
IP address in the 169.254.0.0 subnet with subnet mask 255.255.0.0.
For example, use 169.254.100.201 for your computer.
•OOB port: For access over the OOB port, use a static IP address in the 192.168.0.0
subnet with subnet mask 255.255.0.0.
For example, use 192.168.0.201 and 255.255.255.0 for your computer.
2. Connect an Ethernet cable from an Ethernet port on your computer to either an
Ethernet network port on the switch or to the OOB port on the switch.
3. Launch a web browser.
Audio Video User Manual9Getting Started with the AV UI

4. Enter the default IP address of the switch in the web browser address field:
•Ethernet network port: For access over an Ethernet network port, enter
http://169.254.100.100.
•OOB port: For access over the OOB port, enter http://192.168.0.239.
The login page displays.
5. In the Login Name field, enter admin as the user name, in the Password field, enter
your local device password, and click the Login button.
The first time that you log in, no password is required. However, you then must
specify a local device password to use each subsequent time that you log in.
The Overview page displays.
Log in to the AV UI with a known IP address
If you did not assign a static IP address to the switch but let a DHCP server in your
network assign an IP address to switch, determine the IP address by accessing the DHCP
server or by using an IP scanner utility.
The procedures in this manual assume that you know the IP address of your switch.
To use a known IP address to access the switch over the AV UI:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. In the Login Name field, enter admin as the user name, in the Password field, enter
your local device password, and click the Login button.
The first time that you log in, no password is required. However, you then must
specify a local device password to use each subsequent time that you log in.
The Overview page displays.
Save the running configuration to the startup
configuration
After you make changes on a page of the AV UI and click the Apply or Save button,
your changes are saved for the current session but are not retained when you restart
the switch. That is, your running configuration is not saved to the startup configuration
(the startup-config file), which means that it is not yet permanently saved.

Audio-Video Profile Templates and
Network Profiles
The switch provides preconfigured audio-video (AV) profile templates that you can
configure and assign to switch ports and VLANs, thereby creating network profiles.
You can also set up your own AV profile templates.
These are the essential differences between an AV profile template and a network
profile:
•AV profile template: A preconfigured or custom template with QoS, multicast, or
PTP settings, or a combination of these settings, that you can apply to multiple
network profiles.
•Network profile: An AV profile template that you configured and assigned to one
or more switch ports, to a VLAN, and as an option, to a specific IP address.
The chapter contains the following sections:
• Overview of preconfigured AV profile templates
• Network profiles
• Custom AV profile templates
• Auto-Trunk overview
• Enable or disable Auto-Trunks
12
Overview of preconfigured AV profile
templates
An AV profile template integrates NETGEAR proprietary settings, allowing you to
optimize specific audio and video environments. You can use an AV profile template
to create one or multiple network profiles. For example, you could use the same AV
profile template to set up three network profiles based on a location within a building:
one network profile for the lobby, one for the theater, and one for the patio.
The switch provides the following preconfigured AV profile templates:
•Audio Dante: Use this template to connect the switch to Dante audio devices and
their controller.
•Data: Use this template to connect the switch to streaming ACN (sACN), Art-Net,
mobile ad hoc network (MANET), and other network devices as well as to computers.
•Audio Q-SYS: Use this template to connect the switch to Q-SYS audio devices and
their controller.
•Video with Q-SYS audio: Use this template to connect the switch to IP video
encoders for transmitting video, IP video decoders for receiving video, and a
controller for these devices when Q-SYS audio is supported in the same VLAN.
This template can support devices such as Crestron DM NVX systems, AMX SVSI
products, Aurora Multimedia products, Atlona products, Dante video products, and
products that comply with standardization by the SDVoE Alliance.
•Video with AES67 audio: Use this template to connect the switch to IP video
encoders for transmitting video, IP video decoders for receiving video, and a
controller for these devices when AES67 audio is supported in the same VLAN.
This template can support devices such as Crestron DM NVX systems, AMX SVSI
products, Aurora Multimedia products, Atlona products, Dante video products, and
products that comply with standardization by the SDVoE Alliance.
•Audio-over-IP AVB: Use this template to connect the switch to Audio Video Bridging
(AVB) devices.
•Video: Use this template to connect the switch to IP video encoders for transmitting
video, IP video decoders for receiving video, and a controller for these devices when
audio is sent and received from the video nodes using another VLAN ID.
This template can support devices such as Crestron DM NVX systems, AMX SVSI
products, Aurora Multimedia products, Atlona products, Dante video products, and
products that comply with standardization by the SDVoE Alliance.
•Audio-over-IP AES67: Use this template to connect the switch to AES67 audio
devices and their controller.

Custom AV profile templates
You can create your own AV profile template. After you do so, you can use the custom
AV profile template to set up one or multiple network profiles (see Use an AV profile
template to configure and assign a network profile on page 15).
The advantage of a custom AV profile template is that you can decide whether to enable
multicast, PTP, and QoS. If you enable QoS, you can specify either a DSCP or CoS
configuration.
Create a custom AV profile template
Before you create a custom AV profile template, consider the following:
•Does the template require multicast to be enabled?
•Does the template require Precision Time Protocol (PTP) to be enabled?
•Does the template require QoS to be enabled, and if so, in a DSCP or CoS
configuration?
To add one or more QoS configurations, you need knowledge about configuring
QoS in a network.
Note: You can enable PTP and multicast for a custom AV profile template but you
cannot configure the PTP and multicast settings in the AV UI. For DSCP and CoS, you
can configure limited settings in the AV UI. To configure PTP and multicast settings and
all DSCP and CoS settings that are available on the switch, use the main UI or the CLI.
For more information, see the main user manual or the CLI command reference manual,
both of which you can download by visiting netgear.com/support/download.
To create a custom AV profile template:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. In the Login Name field, enter admin as the user name, in the Password field, enter
your local device password, and click the Login button.
The first time that you log in, no password is required. However, you then must
specify a local device password to use each subsequent time that you log in.

5. At the top right of the Profile Templates table, click the Create AV Template link.
The Create AV Profiles window displays.
6. In the Profile Type field, enter a name for the type of service that the template can
provide.
7. In the Profile Description field, enter a description for the template.
8. To enable multicast, click the Multicast button so that it turns green.
By default, multicast is disabled and the button is gray.
9. To enable PTP, click the PTP button so that it turns green.
By default, PTP is disabled and the button is gray.
10. To add a QoS configuration to the template, do the following:
a. To the right of the Quality of Service section, click the Add QoS link.
b. The fixed selection from the QoS Type menu is DSCP, but this setting also
includes CoS.
•In an incoming IP packet, the switch applies QoS according to the information
in the DiffServ Code Point (DSCP) field.
•In an incoming Ethernet frame, the switch applies QoS according to the
information in the Class of Service (CoS) field.
You must select a value from the Code Point menu, a value from the Priority
menu, and a selection from the Scheduler Type menu.
c. From the Code Point menu, select a value from 0to 63.
The DSCP value that you select allows an incoming IP packet to be mapped to
the egress queue that you select from the Priority menu in the following step.
d. From the Priority menu, select the priority value for the egress queue from 0to
number 7.
The priority goes from low (0) to high (7). For example, traffic with a priority value
of 0 is for most data traffic and is sent using best effort. Traffic with a higher
priority, such as 6 or 7, might be time-sensitive traffic, such as voice or video.
The priority value for the egress queue applies to either DSCP or CoS.
e. From the Scheduler Type menu, select one of the following types for traffic to
which CoS is applied:
•Weighted: The switch uses the weighted round robin (WRR) algorithm to
associate a weight with each queue.
•Strict: The switch services traffic with the highest priority on a queue first.

Auto-Trunk overview
Auto-trunk is a feature that lets the switch automatically enable Trunk mode on capable
physical links and LAG interfaces between partner devices. A trunk can carry all active
VLANs. By default, the Auto-Trunk feature is enabled on the switch.
If the switch automatically configures a port as a trunk (that is, an Auto-Trunk), all VLANs
on the switch become part of the trunk, allowing automatic configuration of all VLANs
on the switch and on the partner device with which the trunk is established.
Before the switch configures an Auto-Trunk, the switch first detects the physical links
with the partner device that also supports the Auto-Trunk feature, and then automatically
configures the ports that are connected and capable of forming a trunk at both ends.
A trunk carries multiple VLANs and accepts both tagged and untagged packets. Typically,
a connection between the switch and a partner device such as a router, access point,
or another switch functions as a trunk.
Audio Video User Manual23Audio-Video Profile Templates
and Network Profiles
AV Line of Fully Managed Switches M4250 Series
For the switch to form an Auto-Trunk with a partner device, the following are required:
•The Auto-Trunk feature must be supported and globally enabled on the switch and
the partner device. (On all M4250 switch models, the Auto-Trunk feature is enabled
by default.)
•The interconnected ports on both the switch and the partner device must be enabled.
(On all M4250 switch models, all ports are enabled by default.)
•LLDP must be enabled on the interconnected ports on both the switch and the
partner device. (On all M4250 switch models, LLDP is enabled by default on all ports.)
•The interconnected ports on the switch and the partner device must be in the default
switch port mode, which is the General mode. If the ports are in the Access mode
or already in the Trunk mode, an Auto-Trunk cannot be formed on an Auto-LAG.
For an Auto-Trunk, the PVID is automatically set to the management VLAN. If you want
to change the PVID for an Auto-Trunk, change the management VLAN.
The Auto-Trunk feature functions together with the Auto-LAG feature (see Auto-LAG
overview on page 27). After an Auto-LAG is formed, the switch automatically applies
trunk mode (that is, an Auto-Trunk) to the LAG at both ends. In other words, after an
Auto-LAG is formed, the mode for the ports that participate in an Auto-LAG is
automatically changed from the default switch port mode to the trunk port mode, and
the Auto-LAG then becomes an Auto-Trunk.
After a port or an Auto-LAG becomes an Auto-Trunk, all VLANs on the switch become
part of the trunk, and all VLANs on the switch and the partner device can be configured
automatically.
Enable or disable Auto-Trunks
By default, the Auto-Trunk feature is globally enabled but you can globally disable it.

Link Aggregation
Link aggregation groups (LAGs), which are also known as port-channels, allow you to
combine multiple full-duplex Ethernet links into a single logical link. Network devices
treat the aggregation as if it were a single link, which increases fault tolerance and
provides load sharing.
You can create a LAG that includes two or more ports as members and apply the LAG
to a network profile. A LAG can be static or dynamic, and you can configure the LAG
as a trunk. The switch can support multiple LAGs.
The chapter contains the following sections:
• Auto-LAG overview
• Enable or disable Auto-LAGs
• Configure the hash mode for Auto-LAGs
• Create a LAG
• Change a LAG
• Remove a LAG
For more information about the LAG options of the switch, see the main user manual,
which you can download by visiting netgear.com/support/download.

Auto-LAG overview
An Auto-LAG is a LAG that forms automatically between two devices that support the
Auto-LAG feature. An Auto-LAG is a dynamic Layer 2 LAG that is based on the Link
Aggregation Control Protocol (LACP).
Note: A LAG is also referred to as a port channel or an EtherChannel.
The switch can detect the physical links with a partner device and automatically configure
a LAG (that is, an Auto-LAG) on interconnected and capable ports at both ends. The
switch can form one Auto-LAG only with each partner device.
The Auto-LAG feature functions together with the Auto-Trunk feature, which must also
be supported and enabled on the partner device with which the LAG is formed. After
an Auto-LAG is formed, the switch automatically applies trunk mode (that is, an
Auto-Trunk) to the LAG at both ends. In other words, after an Auto-LAG is formed, the
mode for the ports that participate in an Auto-LAG changes from the default switch port
mode to the trunk port mode. For more information about the Auto-Trunk feature, see
Auto-Trunk overview on page 23.
For the switch to form an Auto-LAG with a partner switch, the following are required:
•Both the Auto-LAG and Auto-Trunk features must be supported and globally enabled
on the switch and the partner device. (On all M4250 switch models, the Auto-LAG
and Auto-Trunk features are enabled by default.)
•At least two links must be established between the switch and the partner device,
and these links must support the same speed and duplex mode.
•The links cannot be members of a manually configured static or dynamic LAG.
•LLDP must be enabled on the interconnected ports on the switch and the partner
device. (On all M4250 switch models, LLDP is enabled by default on all ports.)
•The interconnected ports on the switch and the partner device must be in the default
switch port mode, which is the General mode. If the ports are in the Access mode
or already in the Trunk mode, an Auto-Trunk cannot be formed on the Auto-LAG.
An Auto-LAG can form with up to eight interfaces as members. Interfaces are
automatically selected for the Auto-LAG based on whether they are up and available
and on the following conditions:
•The interface is not already manually configured as a member of a LAG.
•The interface is not manually configured as a trunk port or an access port. That is,
the interface must be a general interface.
Audio Video User Manual27Link Aggregation
AV Line of Fully Managed Switches M4250 Series
Note: The switch can support multiple static and dynamic LAGs, but with each partner
device, the switch can support a single Auto-LAG only.

and incoming port in the packet. You can change the hash mode (that is, the load
balancing mode) for the Auto-LAG feature.
The switch balances traffic on a LAG by selecting one of the links in the channel over
which packets must be transmitted. The switch selects the link by creating a binary
pattern from selected fields in a packet and associating that pattern with a particular
link. The hash mode determines which fields in a packet the switch selects.

Supplied power is prioritized according to the port order, up to the total power budget
of the device. On an 8-port model, port 1 receives the highest PoE priority, while port
8 is relegated to the lowest PoE priority.
If the power requirements for attached powered devices (PDs) exceed the total power
budget of the switch, the PoE power to the device on the highest-numbered active PoE
port is disabled to make sure that the devices connected to the higher-priority,
lower-numbered PoE ports are supported first.

or, to select all ports, select the Select All PoE Ports check box .
7. Either leave the default PoE mode (802.3at for PoE+ models; 802.3bt for PoE++
models), or, depending on your network devices and requirements, select one of
the following modes from the PoE Standard menu:
•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.
For PoE+ models, 802.3at is the default setting.
•Pre-802.3bt: The PoE++ port supports Class 4 devices that use 4-pair PoE (4PPoE)
to receive power higher than 30W but that are not compliant with IEEE 802.3bt.
The port also supports the IEEE 802.3at and IEEE 802.3af modes.
•802.3bt-Type3: The PoE++ port supports the IEEE 802.3bt Type 3 mode, the
IEEE 802.3at mode, and the IEEE 802.3af mode.
•802.3bt: The PoE++ port is powered in the IEEE 802.3bt mode and is backward
compatible with IEEE 802.3at and IEEE 802.3af. In this mode, if the switch detects
that the attached PD requests more power than IEEE 802.3at but is not an IEEE

Security
You can configure 802.1X port authentication and the associated RADIUS server settings.
The chapter contains the following sections:
• Port authentication
• Manage port authentication for individual ports
• Manage 802.1X authentication
• Remove port authentication from individual ports
• RADIUS servers
• Configure the basic settings for a RADIUS server
• Remove a RADIUS server
For information about all security options of the switch, see the main user manual, which
you can download by visiting netgear.com/support/download.

Port authentication
With port-based authentication, if 802.1X is enabled both globally and on the port,
successful authentication of any one supplicant attached to the port results in all users
being able to use the port without restrictions. At any time, only one supplicant is allowed
to attempt authentication on a port in this mode. Ports in this mode are under
bidirectional control. 802.1X is the default authentication mode. 802.1X is also referred
to as dot1x.
An 802.1X network includes three components:
•Authenticator: The port that is authenticated before access to system services is
permitted.
•Supplicant: The host that is connected to the authenticated port requesting access
to the system services.
•Authentication server: The external server, for example, the RADIUS server that
performs the authentication on behalf of the authenticator, and indicates whether
the supplicant is authorized to access system services.
For port authentication to function, you must configure at least one RADIUS server (see
RADIUS servers on page 47).
Manage port authentication for individual
ports
After you enable 802.1X port authentication globally, the default port authentication
mode on the ports is Auto.
However, before you enable 802.1X access authentication globally (see Manage 802.1X
authentication on page 45), manually set the port authentication mode of the uplink
port or ports to Authorized to enable the switch to keep its network connection and, if
applicable, Internet connection.
To assign a port authentication mode to individual ports:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.

server. If you disable 802.1X access authentication, port authentication is globally
disabled and the switch allows traffic on any ports without authentication.
Note: Before you enable 802.1X access authentication globally, manually set the port
authentication mode of the uplink port or ports to Authorized (see Manage port
authentication for individual ports on page 44) to enable the switch to keep its network
connection and, if applicable, Internet connection.

RADIUS servers
RADIUS servers provide additional security for networks. A RADIUS server maintains a
user database, which can contain per-user or per-port authentication information. The
switch passes information to the configured RADIUS server, which can authenticate a
user name and password or port and password before authorizing use of the network.
Configure the basic settings for a RADIUS
server
After you enable 802.1X access authentication globally (see Manage 802.1X

Manually control the fans
The switch includes internal fans that support intelligent operation, which enables the
switch to automatically start the operation of the fans, gradually increase the speed of
the fans, and either halt PoE or block traffic if the temperature exceeds a critical level.
You can manually control the fans through either the AV UI (see the following procedure)
or the command-line interface (CLI).
If the fans are functioning in Off mode (which you only can set manually) or in Quiet
mode, the switch automatically manages the fans and turns on the fans or gradually
increases the speed of the fans under the following conditions:
•PoE+ and PoE++ models:Either the temperature detected by the temperature
sensor exceeds its threshold or a PoE budget is exceeded.
•LED tiles model (M4250-12M2XF):Either the temperature detected by the
temperature sensor exceeds its threshold or the switch processes a full traffic load.
•Aggregation model (M4250-16XF):Either the temperature detected by the
temperature sensor exceeds its threshold or the switch processes a full traffic load.
Audio Video User Manual61Manage and Monitor the Switch
AV Line of Fully Managed Switches M4250 Series
Note: For detailed information about temperature thresholds, PoE budgets, and traffic
load conditions that affect the fans, see the hardware installation guide, which you can
download by visiting netgear.com/support/download.

The Overview page displays.
4. In the Fans & Temperature section, select one of the following radio buttons.
•Off: The fans are off and produce no noise. You can only manually set the fans
in Off mode. The following models do not support Off mode.
- M4250-26G4F-PoE++
- M4250-40G8XF-PoE+
- M4250-40G8XF-PoE++
•Quiet: The fans function from 20 or 25 percent (depends on the model) to 100
percent speed. Quiet mode is the default mode. At 20 or 25 percent speed, the
fans produce minimal noise. Fan noise increases at 50 percent speed and even
more so at 75 percent speed. At 100 percent speed, the fans produce
considerable noise.
In Quiet mode, the switch might automatically change back and forth between
Cool mode and Quiet mode until a temperature, PoE budget, or traffic load
condition returns within thresholds.
•Cool: The fans consistently function at 100 percent speed and produce maximum
cooling as well as considerable noise.
The fan setting changes immediately. However, depending on the switch model, if
the temperature detected by the temperature sensor exceeds its threshold, a PoE
budget is exceeded, or a traffic load condition is exceeded, the switch automatically
overrides your manual setting.

Configure port mirroring
Port mirroring lets you select the network traffic of specific switch ports for analysis by
a network analyzer. You can select many switch ports as source ports but only a single
switch port as the destination port.
A packet that is copied to the destination port is in the same format as the original
packet. That means that if the mirror is copying an incoming packet, the copied packet
is VLAN-tagged or untagged as it was received on the source port. If the mirror is copying
an outgoing packet, the copied packet is VLAN-tagged or untagged as it is being
transmitted on the source port.
