Switch Installation

Desktop Hardware Installation

The site where you install the hub stack may greatly affect its performance. When installing, consider the following pointers:

Note: The switch model may be different than the one shown in the example illustrations.

• Install the Switch in a fairly cool and dry place.

• Install the Switch in a site free from strong electromagnetic field generators (such

as motors), vibration, dust, and direct exposure to sunlight.

• Leave at least 10cm of space at the front and rear of the hub for ventilation.

• Install the Switch on a sturdy, level surface that can support its weight, or in an

EIA standard-size equipment rack. For information on rack installation, see the next section, Rack Mounting.

• When installing the Switch on a level surface, attach the rubber feet to the

bottom of each device. The rubber feet cushion the hub and protect the hub case from scratching.

Rack Mount Hardware Installation

The switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the switch’s front panel (one on each side), and secure them with the provided screws.

Note: The switch model may be different than the one shown in the example illustrations.

Then, use screws provided with the equipment rack to mount each switch in the rack.

Set your IPv6 settings

System > IPv6 System Settings

Internet Protocol version 6 (IPv6) is a new IP protocol designed to replace IP version 4 (IPv4). The IPv6 address protocol meets the current requirements of new applications and the never ending growth of the Internet. The IPv6 address space makes more addresses available but it must be approached with careful planning. Successful deployment of IPv6 can be achieved with existing IPv4 infrastructures. With proper planning and design, the transition between IP version 4 and 6 is possible today as well.

Use the IPv6 System Settings page to configure the IPv6 network interface, which is the logical interface used for in-band connectivity with the switch via 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.

1. Log into your switch management page (see “Access your switch management page on page 7).

2. Click on System, and click on IPv6 System Settings.

3. Review the settings. When you have completed making changes, click Apply to save

the settings.

• IPv6 State: The IPv6 address for the IPv6 network interface is set in auto

configuration mode if this option is enabled. The default value is Disable. Auto configuration can be enabled only when DHCPv6 is not enabled on any of the management interfaces. DHCPv6 Client: This option only displays when DHCPv6 is enabled.

• IPv6 Unicast Address / Prefix Length: The IPv6 Unicast Address is an identifier

for a single interface, on a single node. A packet that is sent to a unicast address is delivered to the interface identified by that address. Add the IPv6 prefix and prefix length to the IPv6 System Settings interface.

• IPv6 Static Gateway: Specifies the corresponding Gateway of the IP address

entered into the field.

• IPv6 Dynamic Gateway: To configure the switch to automatically obtain its IP

configuration from a DHCP server on your network.

”

• NS Retransmit Time Settings: A constant that defines a nonzero number of

seconds between periodic reauthentication of the client. The field is 1~3600 seconds. The default setting is 1 second.

• Link Local Address Settings: A link-local address is an IPv6 unicast address that

can be automatically configured on any interface using the link-local prefix FE80::/10 (1111 1110 10) and the interface identifier in the modified EUI-64 format. Link-local addresses are used in the neighbor discovery protocol and the stateless autoconfiguration process. Nodes on a local link can use link-local addresses to communicate; the nodes do not need globally unique addresses to communicate. IPv6 devices must not forward packets that have link-local source or destination addresses to other links.

• Automatic Link Local Address: A link local address has a prefix of FE80, is not

routable, and can be used for communication only on the local network. Only one link local address is supported. If a link local address exists on the interface, this entry replaces the address in the configuration.

• Link Local Address/Prefix length: Enter the Link Local Address/Prefix Length.

• Port - Specifies the port number. The All value indicates ports 1 through 48 on

the Switch. You cannot change this parameter. You can use the All row value in the Port column to apply Admin Status, Mode, Jumbo, Flow Contrl, EAP, BPDU settings to all ports at the same time.

TRENDnet User’s Guide

• Trunk - This parameter indicates the trunk group number. A number in this

column indicates that the port has been added to a trunk using static or dynamic 802.3ad LACP link aggregation.

• Type - This parameter indicates the port type. On the Switch, the port type is

1000TX for 10/100Base-T twisted-pair ports (1-48) and 100FX or 1000TX for the SFP ports (49F-50F) for copper or fiber SFP type.

• Link Status - This parameter indicates the status of the link between the port

and the end node connected to the port. The possible values are:

o Up -This parameter indicates a valid link exists between the port and

the end node.

o Down -This parameter indicates the port and the end node have not

established a valid link.

Admin. Status: This parameter indicates the operating status of the port. You can use this parameter to enable or disable a port. You may want to disable a port and prevent packets from being forwarded if a problem occurs with the node or cable connected to the port. You can enable the port to resume normal operation after the problem has been fixed. You can also disable an unused port to secure it from unauthorized connections. The possible values are:

o Ignore -This parameter applies to the All row only and indicates that

the Admin. Status field must be set individually for each port.

o Enabled - This parameter indicates the port is able to send and receive

Ethernet frames.

o Disabled - This parameter indicates the port is not able to send and

receive Ethernet frames.

• Mode: This parameter indicates the speed and duplex mode settings for the

port. You can use this parameter to set the speed and duplex mode of a port. The possible settings are:

o Ignore -This parameter indicates that the All setting does not apply to

the Mode field. In other words, each port is set individually.

o Auto -This parameter indicates the port is using Auto-Negotiation to

set the operating speed and duplex mode. The actual operating speed and duplex mode of the port are displayed in parentheses (for

example, “1000/F” for 1000 Mbps full duplex mode) after a port establishes a link with an end node.

o Auto (1000F) -This parameter indicates the port is configured for

1000Mbps operation in Auto-Negotiation mode.

o 1000/Full -This parameter indicates the port is configured for

1000Mbps operation in full-duplex mode.

o 100/Full -This parameter indicates the port is configured for 100Mbps

operation in full-duplex mode.

o 10/Full -This parameter indicates the port is configured for 10Mbps

operation in full-duplex mode.

o 1000/Half -This parameter indicates the port is configured for

1000Mbps operation in half-duplex mode.

o 100/Half -This parameter indicates the port is configured for 100Mbps

operation in half-duplex mode.

o 10/Half -This parameter indicates the port is configured for 10Mbps

operation in half-duplex mode.

Note: When selecting a Mode setting, the following points apply:

o When a twisted-pair port is set to Auto-Negotiation, the end node should

also be set to Auto-Negotiation to prevent a duplex mode mismatch.

o A switch port using Auto-Negotiation defaults to half-duplex if it detects

that the end node is not using Auto-Negotiation. This can result in a mismatch if the end node is operating at a fixed duplex mode of full-duplex. To avoid this problem when connecting an end node with a fixed duplex mode of full-duplex to a switch port, disable Auto-Negotiation on the port and set the port’s speed and duplex mode manually.

o The only valid setting for the SFP ports is Auto-Negotiation.

• Flow Ctrl: Flow Control, This parameter reflects the current flow control setting

on the port. The switch uses a special pause packet to notify the end node to stop transmitting for a specified period of time. The possible values are:

o Ignore - This parameter indicates that the All setting does not apply to

the Flow Control field. In other words, each port is set individually.

o Enabled - This parameter indicates that the port is permitted to use

flow control.

TEG-424WS

TRENDnet User’s Guide

o Disabled - This parameter indicates that the port is not permitted to

use flow control.

• EAP: This parameter reflects the current Extensible Authentication Protocol

(EAP) setting on the port. The possible values are:

o Ignore - This parameter indicates that the All setting does not apply to

the EAP field. In other words, each port is set individually.

o Enabled - This parameter indicates that the port is able to send and

receive EAP packets.

o Disabled - This parameter indicates that the port is disabled and is not

able to send or receive EAP packets.

• BPDU: This parameter reflects the current BPDU setting on the port. The

possible values are:

o Ignore - This parameter indicates that the All setting does not apply to

the BPDU field. In other words, each port is set individually.

o Enabled - This parameter indicates that the switch will pass BPDU

frames through the switch and broadcast them through all other ports.

o Disabled - This parameter indicates that the switch will not pass BPDU

frames through the switch, With RSTP or STP enabled, the switch will receive BPDU frames and process them according to the spanning tree protocol.

Spanning Tree (STP, RSTP, MSTP)

Configure Spanning Tree Protocol settings

Bridge > Spanning Tree > Protocol Settings

Spanning Tree Protocol (STP) provides network topology for any arrangement of bridges/switches. STP also provides a single path between end stations on a network, eliminating loops. Loops occur when alternate routes exist between hosts. Loops in an extended network can cause bridges to forward traffic indefinitely, resulting in increased traffic and reducing network efficiency.

1. Log into your switch management page (see “Access your switch management page on page 7).

2. Click on Bridge.

3. Review the settings. Click Apply to save changes.

• Global STP Status: Select the STP state on the device. The possible field values

are:

o Disable – Disables STP on the device. This is the default value. o Enable – Enables STP on the device.

• Protocol Version: Specifies the Spanning Tree Protocol (STP) mode to enable

on the switch. The possible field values are:

o STP – Enables STP 802.1d on the device. o RSTP – Enables Rapid STP 802.1w on the device. This is the default

value.

o MSTP – Enables Multiple STP 802.1s on the device.

• Bridge Priority: The Bridge Priority has a range 0 to 61440 in increments of

4096. To make this easier for you, the Web Management Utility divides the range into increments. You specify the increment that represents the desired bridge priority value.

• Maximum Age: The Maximum Age defines the amount of time a port will wait

for STP/RSTP information. MSTP uses this parameter when interacting with STP/RSTP domains on the boundary ports. Its range is 6 - 40 seconds

• Hello Time: The Hello Time is frequency with which the root bridge sends out a

BPDU.

• Forward Delay: The Forward Delay defines the time that the bridge spends in

the listening and learning states. Its range is 4 - 30 seconds.

• Transmit Hold Count: The Transmit Hold Count specifies the maximum number

of BPDUs that the bridge can send per second. Its range is 1 - 10.

• Max Hop Count: The Max Hop Count is a parameter set in a BPDU packet when

it originates. It is decremented by 1each time it is retransmitted by the next bridge. When the Hop Count value reaches zero, the bridge drops the BPDU packet. Its range is 6 - 40 hops.

2. Click on Bridge, click on Spanning Tree, and click on Port Settings.

3. Review the settings. For each entry, click Apply to save changes.

• STP Status: Indicates if spanning tree protocol is active or not on the port.

Select one of the following choices from the pull-down menu:

o Enable - The spanning tree protocol is enabled on the port. o Disabled - The spanning tree protocol is disabled on the port. Enable

Disable

Note: BPDU passthrough must be disabled for all ports under Physical interface for STP can be enabled.

• Priority: Indicates the port priority. If two paths have the same port cost, the

bridges must select a preferred path. In some instances this can involve the use of the port priority parameter which is used as a tie breaker when two paths have the same cost.

The range for port priority is 0 to 240. As with bridge priority, this range is broken into increments, in this case multiples of 16. To select a port priority for a port, you enter the desired value. Table 1 lists the values that are valid.

0 16 32 48 64 80 96 112 128 144 160 176 192 208 224 240

• Admin Cost (0 = Auto): The administratively assigned value for the contribution

of this port to the path cost of paths towards the spanning tree root. Writing a value of '0' assigns the automatically calculated default Path Cost value to the port. If the default Path Cost is being used, this object returns '0' when read.

TRENDnet User’s Guide

• External Cost: This defines a metric that indicates the relative cost of

forwarding packets to the specified port list. Port cost can be set automatically or as a metric value. Define a value between 1 and 200000000 to determine the external cost. The lower the number, the greater the probability the port will be chosen to forward packets. The default port cost: 100Mbps port =

200000. Gigabit port = 20000.

• State – Displays the current port spanning tree state. o Blocking - A blocking state does not allow network traffic to be sent or

received on a the port except for BPDU data. A port with a higher path cost to the root bridge than another on the switch causes a switching loop and is placed in the blocking state by the Spanning Tree algorithm. The port’s state may change to the forwarding state if the other links in use fail and the Spanning Tree algorithm determines the port may transition to the forwarding state.

o Listening - This state occurs on a port during the convergence process.

The port in the listening state processes BPDUs and awaits new information that would cause the port to return to the blocking state.

o Learning - While the port does not yet forward frames (packets), in

this state the port does learn source addresses from frames received and adds them to the filtering (switching) database.

o Forwarding - A port that both receives and sends data. This indicates

normal operation. STP continues to monitor the port for incoming BPDUs that indicate the port should return to the blocking state to prevent a loop.

o Disabled - This state is not strictly part of STP. However, a network

administrator can manually disable a port.

• Edge: Indicates if a port is connected to an edge device in the network topology

or not. Selecting the Forcetrue parameter designates the port as an edge port. Edge ports cannot create loops, however an edge port can lose edge port status if a topology change creates a potential for a loop. An edge port normally should not receive BPDU packets. If a BPDU packet is received, it automatically loses edge port status. Selecting the Forcefalse parameter indicates that the port does not have edge port status. Selecting the Auto parameter indicates that the port have edge port status or not have edge port status automatically. The default setting for this parameter is Auto.

• P2P: Choosing the Forcetrue parameter indicates a point-to-point (P2P) shared

link. P2P ports are similar to edge ports however they are restricted in that a P2P port must operate in full-duplex.

Like edge ports, P2P ports transition to a forwarding state rapidly thus benefiting from RSTP. A P2P value of Forcefalse indicates that the port cannot have P2P status. Auto allows the port to have P2P status whenever possible and operate as if the P2P status were true. If the port cannot maintain this status, (for example if the port is forced to half-duplex operation) the P2P status changes to operate as if the P2P value were Forcefalse.

The default setting for this parameter is Auto.

• Restricted Role: Toggle between True and False to set the restricted role state

of the packet. If set to True, the port will never be selected to be the Root port. The default value is False.

• Restricted TCN: Toggle between True and False to set the restricted TCN of the

packet. Topology Change Notification (TCN) is a BPDU that a bridge sends out to its root port to signal a topology change. If set to True, it stops the port from propagating received TCN and to other ports. The default value is False.

• Migrate: Indicates if the port is configured to accept RSTP and STP BPDUs.
