Switch Management and Discovery
Overview
The switch provides administrative management options that let you configure, monitor, and
control the network. Using the local browser interface, you can configure the switch and the
network, including the ports, the management VLAN, VLANs for traffic control, link
aggregation for increased bandwidth, quality of service (QoS) for prioritizing traffic, and
network security.
Initial discovery of the switch on the network requires one of the following tools:
• NETGEAR Smart Control Center (SCC) program. The SCC runs on a Windows-based
computer. You can download the SCC program from netgear.com/support/download/.
For more information about the SCC program see Discover the Switch in a Network With
a DHCP Server on page 12 and Discover the Switch in a Network Without a DHCP
Server on page 13.
• NETGEAR Switch Discovery Tool. If you use a Mac computer, you can use the
NETGEAR Switch Discovery Tool to discover the switch in your network and access the
local browser interface of the switch. For more information about the Switch Discovery
Tool, Use the NETGEAR Switch Discovery Tool to Access the Switch on page 15.
• NETGEAR Insight mobile app. You can also install the NETGEAR Insight mobile app
on an iOS or Android mobile device and discover the IP address of the switch. For more
information about the Insight mobile app, see Use the NETGEAR Insight Mobile App to
Discover the Switch on page 16.
You can also get the IP address of the switch from the DHCP server in the network or use an
IP scanner utility.
After discovery, you can configure the switch using the local browser interface for advanced
setup and configuration of features, or the SCC program for very basic setup. For more
information, see the SCC user manual, which you can download from
netgear.com/support/download/.
Options to Change the Default IP Address
of the Switch
To enable remote management of the switch through a web browser or SNMP, connect the
switch to the network and specify an IP address, subnet mask, and default gateway. The
switch default IP address is 192.168.0.239 and the default subnet mask is 255.255.255.0.
S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch Models GS308T and GS310TP
Get Started User Manual12
To change the default IP address of the switch, use one of the following methods:
• Dynamic assignment through DHCP. DHCP is enabled on the switch by default. If you
connect the switch to a network with a DHCP server, the switch obtains its network
information automatically. You can use the Smart Control Center to discover the
automatically assigned network information. For more information, see Discover the
Switch in a Network With a DHCP Server on page 12.
• Static assignment through the Smart Control Center. If you connect the switch to a
network that does not include a DHCP server, you can use the Smart Control Center to
assign a static IP address, subnet mask, and default gateway. For more information, see
Discover the Switch in a Network Without a DHCP Server on page 13.
• Static assignment by connecting from a local host. If you do not want to use the
Smart Control Center to assign a static address, you can connect to the switch from a
computer in the 192.168.0.0/24 network and change the settings by using the local
browser interface on the switch. For information about how to set the IP address on the
computer so that it is in the same subnet as the default IP address of the switch, see
Configure a Static IP Address From a Directly Connected Computer on page 16.
Discover or Change the Switch IP Address
The following sections describe methods that let you discover or change the IP address of
the switch.
Discover the Switch in a Network With a DHCP Server

Computer
If you do not want to use the Smart Control Center to configure the network information on
the switch, you can change the IP address of the switch by connecting an Ethernet cable
from a computer to the switch.The IP address of the computer must be in the same subnet as
the default IP address on the switch. For most networks, this means that you must change
the IP address of the computer to be on the same subnet as the default IP address of the
switch (192.168.0.239).
To configure a static IP address on the switch:
1. Change the IP settings of your computer to be in the same subnet as the IP settings of
the switch.
If the DHCP client of the switch is enabled and you remove the switch from the network
with the DHCP server, the IP address reverts to the default IP address of 192.168.0.239
with a subnet of 255.255.255.0.

•An SNTP server is configured.
•The switch can contact the SNTP server.
7. Next to Client Mode, select the mode of operation of the SNTP client:
• Unicast. SNTP operates in a point-to-point fashion. A unicast client sends a request
to a designated server at its unicast address and expects a reply from which it can
determine the time and, optionally, the round-trip delay and local clock offset relative
to the server.
• Broadcast. SNTP operates in the same manner as multicast mode but uses a local
broadcast address instead of a multicast address. The broadcast address provides a
single-subnet scope while a multicast address provides an Internet-wide scope.
The default value is Unicast.
8. If the SNTP client mode is Unicast, use the SNTP Server Configuration page to add the IP
address or DNS name of one or more SNTP servers for the switch to poll.

Last Attempt Time The local date and time (UTC) of the last SNTP request or receipt of an unsolicited
message.
Last Attempt Status The status of the last SNTP request or unsolicited message for both unicast and
broadcast modes. If no message was received from a server, a status of Other is
displayed. These values are appropriate for all operational modes.
• Other. The status of the last request is unknown.
• Success. The SNTP operation was successful and the system time was updated.
• Request Timed Out. After an SNTP request was sent to an SNTP server, the
response timer expired before a response from the server was received.
• Bad
Date Encoded. The time provided by the SNTP server is not valid.
• Version
Not Supported. The SNTP version supported by the server is not
compatible with the version supported by the client.
• Server Unsynchronized. The SNTP server is not synchronized with its peers. This
is indicated by the leap indicator field in the SNTP message.
Server IP Address The IP address of the server for the last received valid packet. If no message was
received from any server, an empty string is shown.
Address Type The address type of the SNTP server address for the last received valid packet.
Server Stratum The claimed stratum of the server for the last received valid packet.
Reference Clock ID The reference clock identifier of the server for the last received valid packet.
Server mode The mode of the server for the last received valid packet.
Unicast Server Max
Entries The maximum number of unicast server entries that can be configured on this client.
Unicast Server
Current Entries The number of current valid unicast server entries configured for this client.
Broadcast Count The number of unsolicited broadcast SNTP messages that were received and processed
by the SNTP client since the last reboot.
Configure an SNTP Server
SNTP assures accurate network device clock time synchronization up to the millisecond.
Time synchronization is performed by a network SNTP server. The switch operates only as
an SNTP client and cannot provide time services to other systems.
Time sources are established by strata. Strata define the accuracy of the reference clock.
The higher the stratum (where zero is the highest), the more accurate the clock. The device
receives time from Stratum 1 and above since it is itself a Stratum 2 device.
S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch Models GS308T and GS310TP
Configure System Information User Manual45
The following is an example of strata:
• Stratum 0. A real-time clock is used as the time source, for example, a GPS system.
• Stratum 1. A server that is directly linked to a Stratum 0 time source is used. Stratum 1
time servers provide primary network time standards.
• Stratum 2. The time source is distanced from the Stratum 1 server over a network path.
For example, a Stratum 2 server receives the time over a network link, through NTP, from
a Stratum 1 server.
Information received from SNTP servers is evaluated based on the time level and server
type.
SNTP time definitions are assessed and determined by the following time levels:
•T1. Time that the original request was sent by the client.
•T2. Time that the original request was received by the server.
•T
3. Time that the server sent a reply.
•T
4. Time that the client received the server's reply.
The device can poll unicast server types for the server time.
Polling for unicast information is used for polling a server for which the IP address is known.
SNTP servers that were configured on the device are the only ones that are polled for
synchronization information. T1 through T4 are used to determine server time. This is the
preferred method for synchronizing device time because it is the most secure method. If this
method is selected, SNTP information is accepted only from SNTP servers defined on the
device using the SNTP Server Configuration page.
The device retrieves synchronization information, either by actively requesting information or
at every poll interval.
You can view and modify information for adding and modifying Simple Network Time
Protocol SNTP servers.
Add an SNTP Server
To add an SNTP server:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, 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 Discover or Change the Switch IP
Address on page 12.

The System Information page displays.
5. Select System > Management > Time > SNTP Server Configuration.
The SNTP Server Configuration page displays.
6. From the Server Type menu, select the type of SNTP address to enter in the address field.
The address can be either an IP address (IPv4) or a host name (DNS).
7. In the Address field, specify the IP address or the host name of the SNTP server.
This is a text string of up to 64 characters, containing the encoded unicast IP address or
host name of an SNTP server. Unicast SNTP requests are sent to this address. If this
address is a DNS host name, then that host name is resolved into an IP address each
time an SNTP request is sent to it.
8. If the UDP port on the SNTP server to which SNTP requests are sent is not the standard
port (123), specify the port number in the Port field.
The range is from 1 to 65535. The default value is 123.
9. In the Priority field, specify the priority order which to query the servers.
The SNTP client on the device continues sending SNTP requests to different servers until
a successful response is received, or all servers are exhausted. The priority indicates the
order in which to query the servers. The request is sent to an SNTP server with a priority
value of 1 first, then to a server with a priority value of 2, and so on. If any servers are
assigned the same priority, the SNTP client contacts the servers in the order that they
appear in the table. The range is from 1 to 3. The default value is 1.
10. In the Version field, specify the NTP version running on the server.
The range is 1 to 4. The default value is 4.
11. Click the Add button.
The SNTP server entry is added.

• 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.
8. 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.
•Medium. Medium priority.
• High. High priority.
• Critical. Critical priority.
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.
9. From the Power Mode menu, select the PoE mode that the port must function in:
• 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
S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch Models GS308T and GS310TP
Configure System Information User Manual66
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.
10. From the Power Limit Type menu, select how the port controls the maximum power that it
can deliver:
• 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
(mW) field. This is the default setting.
Note: If a PD does not report its class correctly, use of these options can
preserve additional PoE power by preventing the switch from
delivering more power than the PD requires. However, depending on
which option you select, a PD that does not report its class correctly
might not power up at all.
11. In the Power Limit (mW) field, enter the maximum power (in mW) that the port can deliver.
The range is 3,000–30,000 mW. The default is 30,000 mW.
12. From the Detection Type menu, select how the port detects the attached PD:
•IEEE 802. The port performs a 4-point resistive detection. This is the default setting.
• 4pt802.3af+legacy. The port performs a 4-point resistive detection, and if required,
continues with legacy detection.
•Legacy. The port performs legacy detection.

Configure SNMP
You can configure SNMP settings for SNMPv1/v2 and SNMPv3. The switch software
supports the configuration of SNMP groups and users that can manage traps that the SNMP
agent generates.
The switch uses both standard public MIBs for standard functionality and private MIBs that
support additional switch functionality. All private MIBs begin with a hyphen (-) prefix. The
main object for interface configuration is in -SWITCHING-MIB, which is a private MIB. Some
interface configurations also involve objects in the public MIB, IF-MIB.
Configure the SNMPv1/v2 Community
Only the communities that you define can access to the switch using the SNMP V1 and
SNMP V2 protocols. Only those communities with read/write level access can be used to
change the configuration using SNMP.

Configure LLDP
The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations
on an 802 LAN to advertise major capabilities and physical descriptions. A network manager
can view this information to identify system topology and detect bad configurations on the
LAN.
The following sections describe how you can configure LLDP:
•Configure LLDP Global Settings on page 76
•Configure LLDP Port Settings on page 78
•View the LLDP-MED Network Policy on page 79
•Configure LLDP-MED Port Settings on page 81
•View the Local Information Advertised Through LLDP on page 82
•View LLDP Neighbors Information on page 84
LLDP is a one-way protocol without any request/response sequences. Information is
advertised by stations implementing the transmit function, and is received and processed by
stations implementing the receive function. The transmit and receive functions can be
enabled or disabled separately per port. By default, both transmit and receive are disabled on
all ports. The application is responsible for starting each transmit and receive state machine
appropriately, based on the configured status and operational state of the port.
The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an
enhancement to LLDP with the following features:
•Autodiscovery of LAN policies (such as VLAN, Layer 2 priority, and DiffServ settings),
enabling plug and play networking.
•Device location discovery for creation of location databases.
•Extended and automated power management of Power over Ethernet endpoints.
•Inventory management, enabling network administrators to track their network devices
and determine their characteristics (manufacturer, software and hardware versions,
serial/asset number).
Configure LLDP Global Settings
You can specify the global LLDP and LLDP-MED settings that are applied to the switch.
To configure global LLDP settings:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.

options:
• TLV Advertised Interval. The number of seconds between transmissions of LLDP
advertisements.
• Hold Multiplier. The transmit interval multiplier value, where transmit hold multiplier ×
transmit interval = the time to live (TTL) value that the device advertises to neighbors.
• Re-initializing Delay. The number of seconds to wait before attempting to re-initialize
LLDP on a port after the LLDP operating mode on the port changes.
• Transmit Delay. The minimum number of seconds to wait between transmissions of
remote data change notifications to one or more SNMP trap receivers configured on
the switch.
7. To configure a nondefault value for LLDP-MED, enter a value in the Fast Start Duration
field.
This value sets the number of LLDP packets sent when the LLDP-MED fast start
mechanism is initialized, which occurs when a new endpoint device links with the
LLDP-MED network connectivity device.

DHCP snooping is a useful feature that provides security by filtering untrusted DHCP
messages and by building and maintaining a DHCP snooping binding table. An untrusted
message is a message that is received from outside the network or firewall and that can
cause traffic attacks within your network. The DHCP snooping binding table contains the
MAC address, IP address, lease time, binding type, VLAN number, and interface information
that corresponds to the local untrusted interfaces of a switch. An untrusted interface is an
interface that is configured to receive messages from outside the network or firewall. A

Set Up PoE Timer Schedules
The switch lets you define multiple timer schedules (each with a unique name) that you can
use for PoE power delivery to attached PDs.
After you create a timer schedule, you can associate it with one or more PoE ports (see
Configure the PoE Port Settings on page 64). You can use a separate timer schedule for
each PoE port.
After you associate a timer schedule with a PoE port, the start date and time force the PoE
port to stop delivering power and the stop date and time enable the PoE port to start
delivering power.

Configure VLANs
Adding virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both
bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2
header, which is fast, and like a router, it partitions the network into logical segments, which
provides better administration, security, and management of multicast traffic.
By default, all ports on the switch are in the same broadcast domain. VLANs electronically
separate ports on the same switch into separate broadcast domains so that broadcast
packets are not sent to all the ports on a single switch. When you use a VLAN, users can be
grouped by logical function instead of physical location.
Each VLAN in a network is assigned an associated VLAN ID, which appears in the IEEE
802.1Q tag in the Layer 2 header of packets transmitted on a VLAN. An end station can omit
the tag, or the VLAN portion of the tag, in which case the first switch port to receive the
S350 Series 8-Port Gigabit Ethernet Smart Managed Pro Switch Models GS308T and GS310TP
Configure Switching User Manual112
packet can either reject it or insert a tag using its default VLAN ID. A port can handle traffic for
more than one VLAN, but it can support only one default VLAN ID.
You can define VLAN groups stored in the VLAN membership table. The switch supports up
to 64 VLANs.
The following VLANs are preconfigured on the switch and you cannot delete them:
• VLAN 1. The default VLAN of which all ports are members.
•VLAN 2. The default Auto-VoIP VLAN. By default, this VLAN does not include any
members but you can manually add members.
• VLAN 4089. The Auto-Video VLAN. By default, this VLAN does not include any members
but you can manually add members.

and thus classify traffic based on the source MAC address of the packet.
You define a MAC-to-VLAN mapping by configuring an entry in the MAC-to-VLAN table. An
entry is specified through a source MAC address and a VLAN ID. The MAC-to-VLAN
configurations are shared across all ports of the switch (that is, a system-wide table exists
with MAC address–to–VLAN ID mappings).
When untagged or priority-tagged packets arrive at the switch and entries exist in the
MAC-to-VLAN table, the source MAC address of the packet is looked up. If an entry is found,
the corresponding VLAN ID is assigned to the packet. If the packet is already priority-tagged,
it maintains this value. Otherwise, the priority is set to zero. The assigned VLAN ID is verified
against the VLAN table. If the VLAN is valid, ingress processing on the packet continues.
Otherwise, the packet is dropped. This implies that you can configure a MAC address
mapping to a VLAN that you did not yet create on the switch.
Add a MAC-Based VLAN
To add a MAC-based VLAN:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.

Configure Protocol-Based VLAN Groups
You can use a protocol-based VLAN to define filtering criteria for untagged packets. By
default, if you do not configure any port-based (IEEE 802.1Q) or protocol-based VLANs,
untagged packets are assigned to VLAN 1. You can override this behavior by defining either
port-based VLANs or protocol-based VLANs, or both. Tagged packets are always handled
according to the IEEE 802.1Q standard and are not included in protocol-based VLANs.
If you assign a port to a protocol-based VLAN for a specific protocol, untagged frames that
arrive on that port for that protocol are assigned the protocol-based VLAN ID. Untagged
frames that arrive on the port for other protocols are assigned the port VLAN ID, either the
default PVID (1) or a PVID you specifically assigned to the port (see Configure Port PVID
Settings on page 118).
You define a protocol-based VLAN by creating a group. Each group forms a one-to-one
relationship with a VLAN ID, can include one to three protocol definitions, and can include
multiple ports. When you create a group, you specify a name and a group ID is assigned
automatically.
To configure a protocol-based VLAN group:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.

Configure Auto-VoIP
Voice over Internet Protocol (VoIP) enables telephone calls over a data network. Because
voice traffic is typically more time-sensitive than data traffic, the Auto-VoIP feature provides a
classification for voice packets so that they can be prioritized above data packets, allowing
the switch to provide better Quality of Service (QoS). With the Auto-VoIP feature, voice
prioritization is provided based on the SIP call-control protocol or OUI bits.

Configure Spanning Tree Protocol
The Spanning Tree Protocol (STP) provides a tree topology for any arrangement of network
devices. STP also provides one path between end stations on a network, eliminating loops.
STP (also referred to as “classic” STP) provides a single path between end stations, avoiding
and eliminating loops. For information about configuring the global STP settings for the
switch, see Configure the STP Settings and View the STP Status on page 133.
The switch support the following spanning tree versions:
• CST. Common STP. For information on configuring CST, see Configure and View the
CST Settings on page 135 and Configure and View the CST Port Settings on page 137.
• MSTP. Multiple Spanning Tree Protocol (MSTP, also referred to as MST) supports
multiple instances of spanning tree to efficiently channel VLAN traffic over different
interfaces. For information on configuring MSTP, see Manage MST Settings on page 142
and Configure and View the Port Settings for an MST Instance on page 144.
• RSTP. Rapid STP. Each instance of the spanning tree behaves in the manner specified in
IEEE 802.1w, Rapid Spanning Tree (RSTP), with slight modifications in the working but
not the end effect (chief among the effects is the rapid transitioning of the port to the
forwarding state). For information on viewing the RSTP state, see View Rapid STP
Information on page 141.
The difference between the RSTP and the traditional STP (IEEE 802.1D) is the ability to
configure and recognize full-duplex connectivity and ports that are connected to end
stations, resulting in rapid transitioning of the port to the forwarding state and the
suppression of Topology Change Notification. These features are represented by the
parameters pointtopoint and edgeport. MSTP is compatible with both RSTP and STP. It
behaves in a way that is appropriate for STP and RSTP bridges. An MSTP bridge can be
configured to behave entirely as an RSTP bridge or an STP bridge.
Note: For two bridges to be in the same region, the force version must be
802.1s and their configuration names, digest keys, and revision levels
must match. For additional information about regions and their effect
on network topology, refer to the IEEE 802.1Q standard.

IGMP Snooping Querier Overview
IGMP snooping requires that one central switch or router periodically queries all end-devices
on the network to announce their multicast memberships. This central device is the IGMP
querier. The IGMP query responses, known as IGMP reports, keep the switch updated with
the current multicast group membership on a port-by-port basis. If the switch does not
receive updated membership information in a timely fashion, it stops forwarding multicasts to
the port where the end device is located.
You can configure and display information about IGMP snooping queriers on the network
and, separately, on VLANs.

Configure Layer 2 Loop Protection
Loops inside a network are costly because they consume resources and reduce the
performance of the network. Detecting loops manually can be cumbersome.
The switch can automatically identify loops in the network. You can enable loop protection
per port or globally.
If loop protection is enabled, the switch sends predefined PDU packets to a Layer 2
broadcast destination address (FF:FF:FF:FF:FF:FF) on all ports for which the feature is
enabled. You can selectively disable PDU packet transmission for loop protection on specific
ports even while port loop protection is enabled. If the switch receives a packet with the
previously mentioned broadcast destination address, the source MAC address in the packet
is compared with the MAC address of the switch. If the MAC address does not match, the
packet is forwarded to all ports that are members of the same VLAN, just like any other
broadcast packet. The packet is not forwarded to the port from which it was received.
If the source MAC address matches the MAC address of the switch, the switch can perform
one of the following actions, depending on how you configure the action:
•The port is shut down.
•A log message is generated. (If a syslog server is configured, the log message can be
sent to the syslog server.)
•The port is shut down and a log message is generated.
Loop protection is not intended for ports that serve as uplinks between spanning tree–aware
switches. It is intended for unmanaged switches that drop spanning tree BPDUs. Loop
protection detects physical and logical loops between Ethernet ports on a device. You must
enable loop protection globally before you can enable and configure it at the interface level.
Loop protection is supported on physical interfaces and static LAG interfaces, but not on
dynamic LAG interfaces.
Configure Global Layer 2 Loop Protection
To configure L2 loop protection globally:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
