LAG Settings

The LAG Settings page displays a table of current settings for all LAGs. You can configure the settings of selected LAGs, and reactivate suspended LAGs by launching the Edit LAG Settings page.

To configure the LAG settings or reactivate a suspended LAG:

Procedure

Step 1

Click Port Management > Link Aggregation > LAG Settings.

The LAGs in the system are displayed.

Step 2

Select a LAG, and click Edit.

Step 3

Enter the values for the following fields:

OptionDescription

LAG

 Select the LAG ID number.

LAG Type

Displays the port type that comprises the LAG.

Description

Enter the LAG name or a comment.

Administrative Status

Set the selected LAG to be Up or Down.

Time Range

Select to enable the time range during which the port is in Up state. When the time range is not active, the port is in shutdown. If a time range is configured, it is effective only when the port is administratively up.

Time Range Name

Select the profile that specifies the time range. If a time range is not yet defined, click Edit to go to Time Range

Operational Status

Displays whether the LAG is currently operating.

Operational Time Range State

Displays whether the time range is currently active or inactive.

Auto Negotiation

Enables or disable auto-negotiation on the LAG. Auto-negotiation is a protocol between two link partners that enables a LAG to advertise its transmission speed and flow control to its partner (the Flow Control default is disabled). It is recommended to keep auto-negotiation enabled on both sides of an aggregate link, or disabled on both sides, while ensuring that link speeds are identical.

Administrative Port Speed

Select the speed of the ports in the LAG.
Back Pressure

Check the Enable check box in the Back Pressure area to slow down packet reception speed when the device is congested. This feature is used with half duplex mode, and disables the remote port by preventing it from sending packets and jamming the signal.

Auto Advertisement Speed

Select the capabilities to be advertised by the LAG. The options are:

  • All Speed—All LAG speeds and both duplex modes are available.

  • 10M—The LAG advertises a 10 Mbps speed and the mode is full duplex.

  • 100M—The LAG advertises a 100 Mbps speed and the mode is full duplex.

  • 1000M—The LAG advertises a 1000 Mbps speed and the mode is full duplex.

  • 10/100M—The LAG advertises a 10/100 Mbps speed and the mode is full duplex.

  • 10G—The LAG advertises a 10G speed and the mode is full duplex.

Flow Control

Set Flow Control to either Enable or Disable or enable the Auto-Negotiation of Flow Control on the LAG.

Operational Auto Negotiation

Displays the auto-negotiation setting.

Operational LAG Speed

Displays the current speed at which the LAG is operating.

Operational Advertisement

Displays the Administrative Advertisement status. The LAG advertises its capabilities to its neighbor LAG to start the negotiation process. The possible values are those specified in the Administrative Advertisement field.

Current Flow Control

Displays the current Flow Control setting.
