Note: The model showing in illustrations may be different to the one you have.

 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.

o 1000/Half -This parameter indicates the port is

configured for 1000Mbps operation in halfduplex 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 AutoNegotiation. 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.

Bridge

The Bridge session covers most of the web smart switch features including spanning tree, trunk configuration, IGMP snooping, bandwidth control, VLAN, GVRP, and QoS.

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.

Spanning Tree Protocol Settings

Global STP

Status:

Select the STP state on the device.

 Disable: Disables STP on the device. This is the

default value.

 Enable: Enables STP on the device.

Protocol Version:

Specifies the Spanning Tree Protocol (STP) mode to enable on the switch.

This is the default value.

Bridge

Priority:

The Bridge Priority has a range 0 to 61440 in increments of 4096. To make this easier for you, the Web Management 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 1 each 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.

Root Information

Root Bridge:

The root bridge ID in the spanning tree.

Root Cost:

The connection cost on the root port

Root Maximum

Age:

The aging timeout for the root port.

Root Forward

Delay:

The forward delay timer before packet forwarding.

Root Port:

The port number been assigned as root port.

Note: Click Apply in the end of the row to apply the change. BPDU pass-through 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, select a desired value.

Note: Click Apply in the end of the row to apply the change. If you select Ignore on All Ports and click on Apply for all ports, the Admin Cost setting is not changing. If you set the value then click on Apply for all ports, The Admin Cost will be set to the same value.

Admin Cost

(0 = Auto):

The administratively assigned value for the contribution of this port to the path cost of a port. 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.

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 200,000,000 to determine the external cost. The default port cost: 100Mbps port = 200,000. Gigabit port = 20,000.

State:

Displays the current port spanning tree state.

 Blocking: A blocking state does not allow

network traffic to be sent or received on 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.

 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.

 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.

 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.

 Disabled: A port with STP disabled does not

participate in STP. 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 to assign 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 indicates that the port does not have edge port status. Selecting the Auto parameter indicates that the port have edge port
