The following table provides a list of the fields in the Advanced tab of the

LAG Configuration dialog box and their descriptions:

Table 13. LAG Configuration Fields - Advanced Tab

Field

Flow Control

Advertisement

LAG STP Mode

Description

The flow control values advertised by the

LAGs on the selected LAG. These values limit the flow control possibilities to be decided by

Auto-Negotiation.

Enables LAG Spanning Tree. The Spanning

Tree mode creates a logical tree topology out of any arrangement of bridges, resulting in a single path between any two end stations. The

Spanning Tree Mode also provides high fault tolerance. The possible states are:

•

Enable

- Enables the Spanning Tree

Mode.

•

Disable

- Disables the Spanning Tree

Mode.

For more information refer to Spanning Tree

Algorithm (STA) in The Reference Guide.

LAG STP State

STP Admin Edge

The state of the LAG in terms of the Spanning

Tree Protocol. The possible states are:

• Disable - The LAG is disabled.

• Blocking - STP is enabled and currently blocking the LAG. The LAG is effectively disabled to prevent the formation of a loop in the network.

• Forwarding - The LAG is currently forwarding information received.

The administrative state of the edge LAG parameter. Possible states include:

• TRUE - This LAG is assumed to be an edge LAG.

• FALSE - This LAG is assumed not to be an edge-LAG.

Field

STP Oper Edge

STP Admin P2P

STP Oper P2P

STP Admin Path Cost

Description

The operational state of the edge LAG parameter.

• TRUE - This LAG is operating in the state specified in STP Admin Edge.

• FALSE - A BPDU was received by the

LAG.

The administrative point-to-point status of the

LAN segment attached to this LAG. Possible statuses include:

• True - The LAG should always be treated as if it is connected to a point-to-point link.

• forceFalse - The LAG should be treated as having a shared media connection.

• auto - The LAG is considered to have a point-to-point link if it is an Aggregator and all of its members are aggregative, or if the MAC entity is configured for full duplex operation, either through auto-negotiation or by management means.

The operational point-to-point status of the

LAN segment attached to this LAG. It indicates whether a LAG is considered to have a point-to-point connection or not.

The value is determined by STP Admin P2P.

The administratively assigned value for the contribution of this LAG to the path cost of paths towards the spanning tree root. A value of 0 assigns the automatically calculated default Path Cost value to the LAG.

STP Admin Path Cost complements STP Path

Cost, which returns the operational value of the path cost.

STP Path Cost

The operational cost factor used by Spanning

Tree Algorithm to determine the most efficient route for forwarding traffic to its destination while removing loops in the network.

For more information refer to Spanning Tree

Algorithm (STA) in The Reference Guide.

Field Description

STP Force Migration

Port Classification

When checked and in RSTP mode, the LAG is forced to transmit RSTP BPDUs.

The classification of a specific LAG. Port

Classification allows network managers to specify each LAG level’s importance. The possible states are:

•

Regular

- Normal users.

•

Valuable

- Servers or critical users.

For more information refer to Port

Classificationin The Reference Guide.

“Using Dialog Boxes and Tables” on page 28

.

Viewing Port Configuration

The Port Configuration dialog box contains tabs that provide you with information specific to a selected port.

The General tab of the Port Configuration dialog box provides detailed information about the port, such as the port name, type, functionality, status, VLAN ID, mode of operation, and any faults occurring on the port.

The Advanced tab of the Port Configuration dialog box provides detailed information about the port’s STP configuration and port classification.

The 802.1x tab of the Port Configuration dialog box provides detailed information about the port’s 802.1x configuration. For more information about 802.1x security, refer to

Chapter 16, Port Security .

The Power tab of the Port Configuration dialog box provides information about the port’s PoE configuration. For more information about PoE, refer to

Chapter 4, Power Over Ethernet .

The Get/Set Toolbar provides an alternative, quick method to view and change the port’s configuration. For more information on the Get/Set

Toolbar, refer to “Get/Set Toolbar” on page 21 .

* Note: The configuration of ports that participate in a LAG cannot be changed using the Port Configuration dialog box. Use the LAG

Configuration dialog box instead.
