CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main applications and features of the Switch. It also introduces the
ways you can manage the Switch.
1.1 Introduction
The GS-2750 is a stand-alone layer 3 Gigabit Ethernet (GbE) switch. It comes with 44 10/100/
1000 Mbps Ethernet ports, 4 Dual Personality interfaces (each consisting of one RJ-45 Gigabit
port and one slot for a mini-GBIC transceiver (SFP module) with one port active at a time) and
two mini-GBIC transceivers for fiber-optic uplink connections.
This section shows a few examples of using the Switch in various network environments.
See Chapter 41 on page 303 for a full list of software features available on the Switch.
1.1.1 Bridging Example
In this example the Switch connects different company departments (RD and Sales) to the
corporate backbone. It can alleviate bandwidth contention and eliminate server and network
bottlenecks. All users that need high bandwidth can connect to high-speed department servers
via the Switch. You can provide a fast uplink connection by using the Gigabit uplink ports on
the Switch.

1.1.2 High Performance Switching Example
The Switch is ideal for connecting two geographically dispersed networks that need high
bandwidth. In the following example, a company uses the Gigabit uplink ports to connect the
headquarters to a branch office network. Within the headquarters network, a company can use
trunking to group several physical ports into one logical higher-capacity link. Trunking can be
used with copper cabling over relatively shorter distances than fiber-optic connections.

1.1.3 Gigabit Ethernet to the Desktop
The Switch is an ideal solution for small networks which demand high bandwidth for a group
of heavy traffic users. You can connect computers and servers directly to the Switch’s port or
connect other switches to the Switch. Use the Gigabit uplink ports to provide high speed
access to a data server and the Internet. The uplink ports support a fiber-optic connection
which alleviate the distance limitations of copper cabling.
In this example, all computers can share high-speed applications on the server and access the
Internet. To expand the network, simply add more networking devices such as switches,
routers, computers, print servers and so on.
Figure 3 Gigabit to the Desktop
Internet
Chapter 1 Getting to Know Your Switch
1.1.4 IEEE 802.1Q VLAN Application Example
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Stations on a logical network belong to one or more groups. With
VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s)
unless such traffic first goes through a router.
For more information on VLANs, refer to Chapter 8 on page 85.
1.1.4.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain, thus increasing
network performance by reducing broadcast traffic. VLAN groups can be modified at any time
by adding, moving or changing ports without any re-cabling.
Shared resources such as a server can be used by all ports in the same VLAN as the server. In
the following figure only ports that need access to the server need to be part of VLAN 1. Ports
can belong to other VLAN groups too.

Figure 4 Shared Server Using VLAN Example
1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This is recommended for everyday management of the Switch using a
(supported) web browser. See Chapter 4 on page 49.
• Command Line Interface. Line commands offer an alternative to the Web Configurator
and may be necessary to configure advanced features. See the CLI Reference Guide.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.
See Section 31.8 on page 258.
• SNMP. The device can be monitored and/or managed by an SNMP manager. See Section
32.3 on page 262.
1.3 Good Habits for Managing the Switch
Do the following things regularly to make the Switch more secure and to manage the Switch
more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the Switch to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the Switch. You could simply restore your last configuration.

CHAPTER 2
Hardware Installation and
Connection
This chapter shows you how to install and connect the Switch.
2.1 Freestanding Installation
1 Make sure the Switch is clean and dry.
2 Set the Switch on a smooth, level surface strong enough to support the weight of the
Switch and the connected cables. Make sure there is a power outlet nearby.
3 Make sure there is enough clearance around the Switch to allow air circulation and the
attachment of cables and the power cord.
4 Remove the adhesive backing from the rubber feet.
5 Attach the rubber feet to each corner on the bottom of the Switch. These rubber feet help
protect the Switch from shock or vibration and ensure space between devices when
stacking.
Figure 5 Attaching Rubber Feet
" Do NOT block the ventilation holes. Leave space between devices when
stacking.
GS-2750 User’s Guide
37
Page 38
Chapter 2 Hardware Installation and Connection
" For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front
and 3.4 inches (8 cm) at the back of the Switch. This is especially important for
enclosed rack installations.
2.2 Mounting the Switch on a Rack
This section lists the rack mounting requirements and precautions and describes the
installation steps.
2.2.1 Rack-mounted Installation Requirements
• Two mounting brackets.
• Eight M3 flat head screws and a #2 Philips screwdriver.
• Four M5 flat head screws and a #2 Philips screwdriver.
1 Failure to use the proper screws may damage the unit.
2.2.1.1 Precautions
• Make sure the rack will safely support the combined weight of all the equipment it
contains.
• Make sure the position of the Switch does not make the rack unstable or top-heavy. Take
all necessary precautions to anchor the rack securely before installing the unit.
2.2.2 Attaching the Mounting Brackets to the Switch
1 Position a mounting bracket on one side of the Switch, lining up the four screw holes on
the bracket with the screw holes on the side of the Switch.
Figure 6 Attaching the Mounting Brackets

Chapter 3 Hardware Overview
3.1.1 1000Base-T Ports
The Switch has 48 1000Base-T auto-negotiating, auto-crossover Ethernet ports (4 of which are
part of the Dual Personality interfaces). In 10/100/1000 Mbps Gigabit Ethernet, the speed can
be 10 Mbps, 100 Mbps or 1000 Mbps. The duplex mode can be both half or full duplex at 10
and 100 Mbps and full duplex only at 1000 Mbps.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000
Mbps) and duplex mode (full duplex or half duplex) of the connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or
crossover Ethernet cable.
3.1.1.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
• Duplex: Auto
• Flow control: Off
3.1.2 Dual Personality Interfaces
There are 4 Dual Personality interfaces, comprising 4 1000Base-T/mini-GBIC combo ports.
For each interface you can connect either to the 1000Base-T port or the mini-GBIC port. The
mini-GBIC ports have priority over the 1000Base-T ports. This means that if a mini-GBIC
port and the corresponding 1000Base-T port are connected at the same time, the 1000Base-T
port will be disabled.
3.1.3 Mini-GBIC Slots
These are 6 slots for Small Form-Factor Pluggable (SFP) transceivers. Four of them are part of
the Dual Personality interfaces and two are used for high speed uplink.
A transceiver is a single unit that houses a transmitter and a receiver. Use a transceiver to
connect a fiber-optic cable to the Switch. The Switch does not come with transceivers. You
must use transceivers that comply with the Small Form-Factor Pluggable (SFP) Transceiver
MultiSource Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for
details.
You can change transceivers while the Switch is operating. You can use different transceivers
to connect to Ethernet switches with different types of fiber-optic connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
1 To avoid possible eye injury, do not look into an operating fiber-optic module’s
connectors.

To connect the power to the Switch, insert the female end of power cord to the power
receptacle on the rear panel. Connect the other end of the supplied power cord to a power
outlet. Make sure that no objects obstruct the airflow of the fans.
The Switch’s AC unit requires a power supply of 100~240 VAC, 0.8 A.
3.2.2 External Backup Power Supply Connector
The Switch supports external backup power supply (BPS).
The Switch constantly monitors the status of the internal power supply. The backup power
supply automatically provides power to the Switch in the event of a power failure. Once the
Switch receives power from the backup power supply, it will not automatically switch back to
using the internal power supply even when the power is resumed.
3.2.3 Console Port
For local management, you can use a computer with terminal emulation software configured
to the following parameters:
• VT100 terminal emulation
• 9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control

" Be careful not to lock yourself and others out of the Switch. If you do lock
yourself out, try using out-of-band management (via the management port) to
configure the Switch.
4.6 Resetting the Switch
If you lock yourself (and others) from the Switch or forget the administrator password, you
will need to reload the factory-default configuration file or reset the Switch back to the factory
defaults.
4.6.1 Reload the Configuration File
Uploading the factory-default configuration file replaces the current configuration file with the
factory-default configuration file. This means that you will lose all previous configurations
and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no
parity, one stop bit and flow control set to none. The password will also be reset to “1234” and
the IP address to 192.168.1.1.
To upload the configuration file, do the following:
1 Connect to the console port using a computer with terminal emulation software. See
Section 3.2 on page 44 for details.
2 Disconnect and reconnect the Switch’s power to begin a session. When you reconnect
the Switch’s power, you will see the initial screen.

CHAPTER 5
Initial Setup Example
This chapter shows how to set up the Switch for an example network.
5.1 Overview
The following lists the configuration steps for the example network:
• Configure an IP interface
• Configure DHCP server settings
• Create a VLAN
• Set port VLAN ID
• Enable RIP
5.1.1 Configuring an IP Interface
On a layer-3 switch, an IP interface (also known as an IP routing domain) is not bound to a
physical port. The default IP address of the Switch is 192.168.1.1 with a subnet mask of
255.255.255.0.
In the example network, since the RD network is already in the same IP interface as the
Switch, you don’t need to create an IP interface for it. However, if you want to have the Sales
network on a different routing domain, you need to create a new IP interface. This allows the
Switch to route traffic between the RD and Sales networks.
Figure 19 Initial Setup Network Example: IP Interface
1 Connect your computer to the MGMT port that is used only for management. Make
sure your computer is in the same subnet as the MGMT port.
GS-2750 User’s Guide

Chapter 5 Initial Setup Example
2 Open your web browser and enter 192.168.0.1 (the default MGMT port IP address) in
the address bar to access the web configurator. See Section 4.2 on page 49 for more
information.
3 Click Basic Setting and IP Setup
in the navigation panel.
4 Configure the related fields in the
IP Setup screen.
For the Sales network, enter
192.168.2.1 as the IP address and
255.255.255.0 as the subnet
mask.
5 In the VID field, enter the ID of
the VLAN group to which you
want this IP interface to belong.
This is the same as the VLAN ID
you configure in the Static
VLAN screen.
6 Click Add to save the settings to
the run-time memory. Settings in
the run-time memory are lost
when the Switch’s power is
turned off.
example
5.1.2 Configuring DHCP Server Settings
You can set the Switch to assign network information (such as the IP address, DNS server,
etc.) to DHCP clients on the network.
For the example network, configure two DHCP client pools on the Switch for the DHCP
clients in the RD and Sales networks.
1 In the web configurator, click IP
Application and DHCP in the
navigation panel and click the
VLAN link.
2 In the VLAN Setting screen,
specify the ID of the VLAN to
which the DHCP clients belong,
the starting IP address pool,

5.1.3 Creating a VLAN
VLANs confine broadcast frames to the VLAN group in which the port(s) belongs. You can
do this with port-based VLAN or tagged static VLAN with fixed port members.
In this example, you want to configure port 1 as a member of VLAN 2.

Chapter 5 Initial Setup Example
" The VLAN Group ID field in this screen and the VID field in the IP Setup
screen refer to the same VLAN ID.
3 Since the VLAN2 network is connected to port 1 on the Switch, select Fixed to
configure port 1 to be a permanent member of the VLAN only.
4 To ensure that VLAN-unaware devices (such as computers and hubs) can receive frames
properly, clear the TX Tagging check box to set the Switch to remove VLAN tags
before sending.
5 Click Add to save the settings to the run-time memory. Settings in the run-time memory
are lost when the Switch’s power is turned off.
5.1.4 Setting Port VID
Use PVID to add a tag to incoming untagged frames received on that port so that the frames
are forwarded to the VLAN group that the tag defines.
In the example network, configure 2 as the port VID on port 1 so that any untagged frames
received on that port get sent to VLAN 2.

7.4 Introduction to VLANs
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Devices on a logical network belong to one group. A device can
belong to more than one group. With VLAN, a device cannot directly talk to or hear from
devices that are not in the same group(s); the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security
among the subscribers. When properly configured, VLAN prevents one subscriber from
accessing the network resources of another on the same LAN, thus a user will not see the
printers and hard disks of another user on the same network.
GS-2750 User’s Guide
75
Page 76
Chapter 7 Basic Setting
VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast
packets go to each and every individual port. With VLAN, all broadcasts are confined to a
specific broadcast domain.
" VLAN is unidirectional; it only governs outgoing traffic.
See Chapter 8 on page 85 for information on port-based and 802.1Q tagged VLANs.

GARP Timer: Switches join VLANs by making a declaration. A declaration is made by issuing a Join
message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All
message terminates all registrations. GARP timers set declaration timeout values. See Section 8.1 on
page 85 for more background information.
Join Timer Join Timer sets the duration of the Join Period timer for GVRP in milliseconds. Each
port has a Join Period timer. The allowed Join Time range is between 100 and
65535 milliseconds; the default is 200 milliseconds. See Section 8.1 on page 85 for
more background information.

Priority Queue Assignment
IEEE 802.1p defines up to eight separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service. Frames without an explicit priority tag are given the default
priority of the ingress port. Use the following fields to configure the priority level-to-physical queue
mapping.
The Switch has eight physical queues that you can map to the 8 priority levels. On the Switch, traffic
assigned to higher index queues gets through faster while traffic in lower index queues is dropped if
the network is congested.
Priority Level (The following descriptions are based on the traffic types defined in the IEEE 802.1d
standard (which incorporates the 802.1p).
Level 7 Typically used for network control traffic such as router configuration messages.

7.6 IP Setup
Use the IP Setup screen to configure the default gateway device, the default domain name
server and add IP domains.
7.6.1 IP Interfaces
The Switch needs an IP address for it to be managed over the network. The factory default IP
address is 192.168.1.1. The subnet mask specifies the network number portion of an IP
address. The factory default subnet mask is 255.255.255.0.
On the Switch, as a layer-3 device, an IP address is not bound to any physical ports. Since each
IP address on the Switch must be in a separate subnet, the configured IP address is also known
as IP interface (or routing domain). In addition, this allows routing between subnets based on
the IP address without additional routers.
You can configure multiple routing domains on the same VLAN as long as the IP address
ranges for the domains do not overlap. To change the IP address of the Switch in a routing
domain, simply add a new routing domain entry with a different IP address in the same subnet.

Type This field displays 10/100/1000M for a 1000Base-T connection and the Dual
Personality interfaces, and 1000M for Mini-GBIC uplink ports.
Speed/Duplex Select the speed and the duplex mode of the Ethernet connection on this port. The
choices are Auto, 10M/Half Duplex, 10M/Full Duplex, 100M/Half Duplex and
100M/Full Duplex for a 1000Base-T connection. 1000M/Full Duplex is supported by
both 1000Base-T (copper) and 1000Base-X (fiber-optic) connections.
Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port
automatically to obtain the connection speed and duplex mode that both ends
support. When auto-negotiation is turned on, a port on the Switch negotiates with the
peer automatically to determine the connection speed and duplex mode. If the peer
port does not support auto-negotiation or turns off this feature, the Switch determines
the connection speed by detecting the signal on the cable and using half duplex
mode. When the Switch’s auto-negotiation is turned off, a port uses the preconfigured speed and duplex mode when making a connection, thus requiring you to
make sure that the settings of the peer port are the same in order to connect.
Flow Control A concentration of traffic on a port decreases port bandwidth and overflows buffer
memory causing packet discards and frame losses. Flow Control is used to regulate
transmission of signals to match the bandwidth of the receiving port.
The Switch uses IEEE 802.3x flow control in full duplex mode and backpressure flow
control in half duplex mode.
IEEE 802.3x flow control is used in full duplex mode to send a pause signal to the
sending port, causing it to temporarily stop sending signals when the receiving port
memory buffers fill.
Back Pressure flow control is typically used in half duplex mode to send a "collision"
signal to the sending port (mimicking a state of packet collision) causing the sending
port to temporarily stop sending signals and resend later. Select Flow Control to
enable it.

CHAPTER 8
VLAN
The type of screen you see here depends on the VLAN Type you selected in the Switch Setup
screen. This chapter shows you how to configure 802.1Q tagged and port-based VLANs.
8.1 Introduction to IEEE 802.1Q Tagged VLANs
A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN
membership of a frame across bridges - they are not confined to the switch on which they were
created. The VLANs can be created statically by hand or dynamically through GVRP. The
VLAN ID associates a frame with a specific VLAN and provides the information that switches
need to process the frame across the network. A tagged frame is four bytes longer than an
untagged frame and contains two bytes for the TPID (Tag Protocol Identifier, residing within
the type/length field of the Ethernet frame) and two bytes for the TCI (Tag Control
Information, starting after the source address field of the Ethernet frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet
switches. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not
be forwarded as it is to an untagged port. The remaining twelve bits define the VLAN ID,
giving a possible maximum number of 4,096 VLANs. Note that user priority and VLAN ID
are independent of each other. A frame with VID (VLAN Identifier) of null (0) is called a
priority frame, meaning that only the priority level is significant and the default VID of the
ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to
identify priority frames and the value 4095 (FFF) is reserved, so the maximum possible
number of VLAN configurations is 4,094.

8.1.1 Forwarding Tagged and Untagged Frames
Each port on the Switch is capable of passing tagged or untagged frames. To forward a frame
from an 802.1Q VLAN-aware switch to an 802.1Q VLAN-unaware switch, the Switch first
decides where to forward the frame and then strips off the VLAN tag. To forward a frame
from an 802.1Q VLAN-unaware switch to an 802.1Q VLAN-aware switch, the Switch first
decides where to forward the frame, and then inserts a VLAN tag reflecting the ingress port's
default VID. The default PVID is VLAN 1 for all ports, but this can be changed.
A broadcast frame (or a multicast frame for a multicast group that is known by the system) is
duplicated only on ports that are members of the VID (except the ingress port itself), thus
confining the broadcast to a specific domain.

Chapter 8 VLAN
8.2 Automatic VLAN Registration
GARP and GVRP are the protocols used to automatically register VLAN membership across
switches.
8.2.1 GARP
GARP (Generic Attribute Registration Protocol) allows network switches to register and deregister attribute values with other GARP participants within a bridged LAN. GARP is a
protocol that provides a generic mechanism for protocols that serve a more specific
application, for example, GVRP.
8.2.1.1 GARP Timers
Switches join VLANs by making a declaration. A declaration is made by issuing a Join
message using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All
message terminates all registrations. GARP timers set declaration timeout values.
8.2.2 GVRP
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to register necessary VLAN members on ports across the network. Enable this
function to permit VLAN groups beyond the local Switch.
Please refer to the following table for common IEEE 802.1Q VLAN terminology.

8.3 Port VLAN Trunking
Enable VLAN Trunking on a port to allow frames belonging to unknown VLAN groups to
pass through that port. This is useful if you want to set up VLAN groups on end devices
without having to configure the same VLAN groups on intermediary devices.
The following figure describes VLAN Trunking. Suppose you want to create VLAN groups 1
and 2 (V1 and V2) on devices A and B. Without VLAN Trunking, you must configure
VLAN groups 1 and 2 on all intermediary switches C, D and E; otherwise they will drop
frames with unknown VLAN group tags. However, with VLAN Trunking enabled on a
port(s) in each intermediary switch you only need to create VLAN groups in the end devices
(A and B). C, D and E automatically allow frames with VLAN group tags 1 and 2 (VLAN
groups that are unknown to those switches) to pass through their VLAN trunking port(s).

8.5 Static VLAN
Use a static VLAN to decide whether an incoming frame on a port should be
• sent to a VLAN group as normal depending on its VLAN tag.
• sent to a group whether it has a VLAN tag or not.
• blocked from a VLAN group regardless of its VLAN tag.
You can also tag all outgoing frames (that were previously untagged) from a port with the
specified VID.

Cancel Click Cancel to begin configuring this screen afresh.
8.6 Subnet Based VLANs
Subnet based VLANs allow you to group traffic into logical VLANs based on the source IP
subnet you specify. When a frame is received on a port, the Switch checks if a tag is added
already and the IP subnet it came from. The untagged packets from the same IP subnet are then
placed in the same subnet based VLAN. One advantage of using subnet based VLANs is that
priority can be assigned to traffic from the same IP subnet.
For example, an ISP (Internet Service Provider) may divide different types of services it
provides to customers into different IP subnets. Traffic for voice services is designated for IP
subnet 172.16.1.0/24, video for 192.168.1.0/24 and data for 10.1.1.0/24. The Switch can then
be configured to group incoming traffic based on the source IP subnet of incoming frames.
You can then configure a subnet based VLAN with priority 6 and VID of 100 for traffic
received from IP subnet 172.16.1.0/24 (voice services). You can also have a subnet based
VLAN with priority 5 and VID of 200 for traffic received from IP subnet 192.168.1.0/24
(video services). Lastly, you can configure VLAN with priority 3 and VID of 300 for traffic
received from IP subnet 10.1.1.0/24 (data services). All untagged incoming frames will be
classified based on their source IP subnet and prioritized accordingly. That is, video services
receive the highest priority and data the lowest.

8.8 Protocol Based VLANs
Protocol based VLANs allow you to group traffic into logical VLANs based on the protocol
you specify. When an upstream frame is received on a port (configured for a protocol based
VLAN), the Switch checks if a tag is added already and its protocol. The untagged packets of
the same protocol are then placed in the same protocol based VLAN. One advantage of using
protocol based VLANs is that priority can be assigned to traffic of the same protocol.

8.11 Port-based VLAN Setup
Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.
Port-based VLANs are specific only to the Switch on which they were created.
" When you activate port-based VLAN, the Switch uses a default VLAN ID of 1.
You cannot change it.
" In screens (such as IP Setup and Filtering) that require a VID, you must enter
1 as the VID.

The port-based VLAN setup screen is shown next. The CPU management port forms a VLAN
with all Ethernet ports.
8.11.1 Configure a Port-based VLAN
Select Port Based as the VLAN Type in the Switch Setup screen and then click VLAN
from the navigation panel to display the following screen. Select either All Connected or Port
Isolated from the drop-down list depending on your VLAN and VLAN security requirements.
If VLAN members need to communicate directly with each other, then select All Connected.
Select Port Isolated if you want to restrict users from communicating directly. Click Apply to
save your settings.
The following screen shows users on a port-based, all-connected VLAN configuration.

All connected means all ports can communicate with each other, that is, there are no
virtual LANs. All incoming and outgoing ports are selected. This option is the most
flexible but also the least secure.
Port isolation means that each port can only communicate with the CPU
management port and cannot communicate with each other. All incoming ports are
selected while only the CPU outgoing port is selected. This option is the most limiting
but also the most secure.
After you make your selection, click Apply (top right of screen) to display the screens
as mentioned above. You can still customize these settings by adding/deleting
incoming or outgoing ports, but you must also click Apply at the bottom of the screen.

other, you must define the ingress port for both ports. The numbers in the top row
denote the incoming port for the corresponding port listed on the left (its outgoing
port). CPU refers to the Switch management port. By default it forms a VLAN with all
Ethernet ports. If it does not form a VLAN with a particular port then the Switch cannot
be managed from that port.
