(1)Gigabit Port

(2)SFP with 100FX module

(3)SFP with 1000X module

Trunk: This cell displays the trunk status with 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 cell displays the port type. On the Switch, the port type is 1000TX for 10/100/1000Base-T twisted-pair ports (1-8) and 100FX or 1000X for the SFP ports (7F-8F) for copper or fiber SFP type.

Link Status: This cell displays the network link status of the port. The possible values are:

Up: This value indicates a valid link exists between the port and the end node.

Down: This value 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.

All Ports:

If you select Ignore and click on Apply for all ports, the Admin Status is not changing. If you select Enabled then

o 100/Half -This parameter indicates the port is configured for 100Mbps operation in half-duplex mode.

o10/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:

oWhen 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.

oA switch port using Auto-Negotiation defaults to halfduplex 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.

oThe only valid setting for the SFP ports is AutoNegotiation.

The Bridge session covers most of the web smart switch features including spanning tree, trunk configuration, IGMP snooping, bandwidth control, VLAN, VGRP, 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 Select the STP state on the device.

Status: 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.

STP: Enables STP 802.1D on the device.

RSTP: Enables Rapid STP 802.1w on the device. This is the default value.

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 The Transmit Hold Count specifies the maximum Count: 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 The aging timeout for the root port.

Age:

Root Forward The forward delay timer before packet forwarding.

Delay:

Root Port: The port number been assigned as root port. Click Apply to apply the change to the switch

	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.

	Admin Cost		The administratively assigned value for the

(0 = Auto): 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 status or not have edge port status

automatically. The default setting for this parameter is

Auto.

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.

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.
