XS712T Smart Switch
Switch Management Interface
The NETGEAR XS712T Smart Switch contain an embedded web server and management
software for managing and monitoring switch functions. The XS712T functions as a simple
switch without the management software. However, you can use the management software
to configure more advanced features that can improve switch efficiency and overall network
performance.
Web-based management lets you monitor, configure, and control your switch remotely using
a standard web browser instead of using expensive and complicated SNMP software
products. From your web browser, you can monitor the performance of your switch and
optimize its configuration for your network. You can configure all switch features, such as
VLANs, QoS, and ACLs, by using the web management interface.
NETGEAR provides the Smart Control Center utility with this product. This program runs
under Microsoft Windows XP, Windows 2000, or Windows Vista and provides a front end that
discovers the switches on your network segment (L2 broadcast domain). When you power up
your switch for the first time, use the Smart Control Center to discover the switch and view
the network information that has been automatically assigned to the switch by a DHCP
server; or, if no DHCP server is present on the network, use the Smart Control Center to
discover the switch and assign static network information.
In addition to enabling NETGEAR switch discovery, the Smart Control Center provides
several utilities to help you maintain the NETGEAR switches on your network, such as
password management, firmware upgrade, and configuration file backup. For more
information, see
Appendix A, Smart Control Center Utilities.
Connect the Switch to the Network
To enable remote management of the switch through a web browser or SNMP, you must
connect the switch to the network and configure it with network information (an IP address,
subnet mask, and default gateway). The switch has a default IP address of 192.168.0.239
and a default subnet mask of 255.255.255.0.
To change the default network information on the switch, use one of the following three
methods:
• Dynamic assignment through DHCP. DHCP is enabled by default on the switch. 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

Note: Make sure that the VLAN to be configured as the management
VLAN exists. And make sure that the PVID of at least one port that is
a port of the VLAN is the same as the management VLAN ID. For
information about creating VLANs and configuring the PVID for a
port, see VLANs on page 84.
The management VLAN is used to establish an IP connection to the switch from a
workstation that is connected to a port in the same VLAN. If not specified, the active
management VLAN ID is 1 (default), which allows an IP connection to be established
through any port.
When the management VLAN is set to a different value, an IP connection can be made
only through a port that is part of the management VLAN. It is also mandatory that the
port VLAN ID (PVID) of the port to be connected in that management VLAN be the same
as the management VLAN ID.
The management VLAN has the following requirements:
• Only one management VLAN can be active at a time.
• When a new management VLAN is configured, connectivity through the existing
management VLAN is lost.
• The management station should be reconnected to the port in the new management
VLAN.

Use the IPv6 Network Configuration screen to configure the IPv6 network interface, which is
the logical interface used for in-band connectivity with the switch through all of the switch's
front-panel ports. The configuration parameters associated with the switch's network
interface do not affect the configuration of the front-panel ports through which traffic is
switched or routed.
To access the switch over a IPv6 network, you must

Field Description
Neighbor State The state of the neighbor cache entry. The following are the states for dynamic
entries in the IPv6 neighbor discovery cache:
• Reach. The neighbor is reachable through the network interface.
• Stale. The neighbor is not known to be reachable, and the switch will begin
the process to reach the neighbor.
• Delay. The neighbor is not known to be reachable, and upper-layer
protocols are attempting to provide reachability information.
• Probe. The neighbor is not known to be reachable, and the device is
attempting to probe for this neighbor.
• Unknown. The reachability status cannot be determined.
Last Updated The amount of time that has passed since the neighbor entry was last updated.
Time
The switch supports the Simple Network Time Protocol (SNTP). You can also set the system
time manually
SNTP assures accurate network device clock time synchronization up to the millisecond.
Time synchronization is performed by a network SNTP server. The switch software operates
only as an SNTP client and cannot provide time services to other systems.
Time sources are established by stratums. Stratums 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.
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 at which the original request was sent by the client.
• T2: Time at which the original request was received by the server.
• T3: Time at which the server sent a reply.
• T4: Time at which 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 have been 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 screen.
The device retrieves synchronization information, either by actively requesting information or
at every poll interval.

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.
• Broadc
ast. SNTP operates in the same manner as multicast mode but uses a local
broadcast address instead of a multicast address. The broadcast address has a
single subnet scope while a multicast address has Internet wide scope.
4. Opt
ionally, configure the following settings to non-default values:
• Port. T

• Broadc
ast Poll Interval. The interval, in seconds, between broadcast poll requests
expressed as a power of two when configured in broadcast mode. Broadcasts
received prior to the expiry of this interval are discarded.
• Unic
ast Poll Timeout. The timeout value, in seconds, to wait for an SNTP response
when configured in unicast mode.
• Unic
ast Poll Retry. The number of times to retry a request to an SNTP server after
the first time-out before attempting to use the next configured server when configured
in unicast mode.

LLDP is a one-way protocol; there are no 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/disabled separately per port. By default, both transmit and receive are enabled 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:
• Auto-discovery 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).

Services—DHCP Snooping
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
trusted interface is an interface that is configured to receive only messages from within the
network.
DHCP snooping acts like a firewall between untrusted hosts and DHCP servers. It also
provides way to differentiate between untrusted interfaces connected to the end-user and
trusted interfaces connected to the DHCP server or another switch.
From the Services configuration menu, you can access the following links:
• Global Configuration
• Interface Configuration
• Binding Configuration
• Persistent Configuration
• Statistics

• Disabled. The interface is considered to be untrusted and could potentially be used to
launch a network attack. DHCP server messages are checked against the bindings
database. On untrusted ports, DHCP snooping enforces the following security rules:
• DHCP packets from a DHCP server (DHCPOFFER, DHCPACK, DHCPNAK,
DHCPRELEASEQUERY) are dropped.
• DHCPRELEASE and DHCPDECLINE messages are dropped if the MAC address
is in the snooping database but the binding's interface is other than the interface
where the message was received.
• DHCP packets are dropped when the source MAC address does not match the
client hardware address if MAC Address Validation is globally enabled.
• Enabled. The interface is considered to be trusted and forwards DHCP server
messages without validation.

Flow Control
IEEE 802.3x flow control works by pausing a port when the port becomes oversubscribed
and dropping all traffic for small bursts of time during the congestion condition. This can lead
to high-priority and/or network control traffic loss. When IEEE 802.3x flow control is enabled,
lower speed switches can communicate with higher speed switches by requesting that the
higher speed switch refrains from sending packets. Transmissions are temporarily halted to
prevent buffer overflows.

Link Aggregation Groups
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 assign the LAG VLAN membership after you create a LAG. The LAG by default
becomes member of default management VLAN (i.e, 1).
A LAG interface can be either static or dynamic, but not both. All members of a LAG must
articipate in the same protocols. A static port-channel interface does not require a partner
p
system to be able to aggregate its member ports.
Static LAGs are supported. When a port is added to a LAG as a static member, it neither
transmit
s nor receives LAGPDUs. The XS712T Smart Switch supports eight LAGs.
The LAGs menu contains links described
• LAG Configuration

LAG Configuration
Use the LAG (Port Channel) Configuration screen to group one or more full-duplex Ethernet

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 has an associated VLAN ID, which displays 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 packet can either
reject it or insert a tag using its default VLAN ID. A given port can handle traffic for more than
one VLAN, but it can only support one default VLAN ID.
The VLAN menu contains links described in the following sections.
• Basic VLAN Configuration
• VLAN Membership Configuration
• VLAN Status
• Port VLAN ID Configuration
• MAC Based VLAN
• Protocol Based VLAN Group Configuration

configurations are shared across all ports of the device (i.e. there is a system wide table that
has MAC address to VLAN ID mappings).
When untagged or priority tagged packets arrive at the switch and entries exist in the MAC to

corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged it
will maintain this value, otherwise the priority will be set to zero. The assigned VLAN ID is
verified against the VLAN table, if the VLAN is valid ingress processing on the packet

Protocol Based VLAN Group Configuration
Protocol-based VLAN can be used to define filtering criteria for untagged packets. By default,
if you do not configure any port- (IEEE 802.1Q) or protocol based VLANs, untagged packets
will be 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 fo
received on that port for that protocol will be assigned the protocol based VLAN ID. Untagged
frames received on the port for other protocols will be assigned the Port VLAN ID, either the
default PVID (1) or a PVID you have specifically assigned to the port using the Port VLAN
Configuration screen.
You define a protocol based VLAN by creating a group. Each group has a one-to-one

the transmission rate is vital. The priority level enables the separation of voice and data traffic
entering the port.
Use the Voice VLAN Configuration screen to co

Auto-VoIP Configuration
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 helps
provide a classification mechanism for voice packets so that they can be prioritized above
data packets in order to provide better Quality of Service (QoS). With the Auto VoIP feature,
voice prioritization is provided based on call-control protocols (SIP, SCCP, H.323) and/or OUI
bits.

Spanning Tree Protocol
The Spanning Tree Protocol (STP) provides a tree topology for any arrangement of bridges.
STP also provides one path between end stations on a network, eliminating loops. Spanning
tree versions supported include Common STP, Multiple STP, and Rapid STP.
Classic STP provides a single path between end stations, avoiding and eliminating loops. For
information about configuring Common STP, see
Multiple Spanning Tree Protocol (MSTP) supports multiple instances of Spanning Tree to
efficiently channel VLAN traffic over different interfaces. 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 Forwarding). The difference between the RSTP and the traditional
STP (IEEE 802.1D) is the ability to configure and recognize full-duplex connectivity and ports
which are connected to end stations, resulting in rapid transitioning of the port to Forwarding
state and the suppression of topology change notification. These features are represented by
the parameters pointtopoint and edgeport. MSTP is compatible to both RSTP and STP. A
MSTP bridge can be configured to behave entirely as a RSTP bridge or a STP bridge.
CST Port Configuration on page 102.
Note: For two bridges to be in the same region, the force version should be
802.1s and their configuration name, digest key, and revision level
should match. For additional information about regions and their
