Configuring 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:

1. Click Port Management > Link Aggregation > LAG Settings.
2. Select a LAG, and click Edit.
3. Enter the values for the following fields:
• LAG—Select the LAG ID number.
• Description—Enter the LAG name or a comment.
• LAG Type—Displays the port type that comprises the LAG.
• Administrative Status—Set the selected LAG to be Up or Down.
• Operational Status—Displays whether the LAG is currently operating.
• 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. If a time range is not yet defined, click Edit to go to the Time Range page.
• Time Range Name—Select the profile that specifies the time range.
• Operational Time-Range State—Displays whether the time range is currently active or inactive.
• Reactivate Suspended LAG—Select to reactivate a port if the LAG has been disabled through the locked port security option or through ACL configurations.
• Administrative 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.
• Operational Auto Negotiation—Displays the auto-negotiation setting.
• Administrative Speed—Select the LAG speed.
• Operational LAG Speed—Displays the current speed at which the LAG is operating.
• Administrative Advertisement—Select the capabilities to be advertised by the LAG. The options are:
• Max Capability—All LAG speeds and both duplex modes are available.
• 10 Full—The LAG advertises a 10 Mbps speed and the mode is full duplex.
• 100 Full—The LAG advertises a 100 Mbps speed and the mode is full duplex.
• 1000 Full—The LAG advertises a 1000 Mbps speed and the mode is full duplex.
• 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.
• Administrative Flow Control—Set Flow Control to either Enable or Disable or enable the Auto-Negotiation of Flow Control on the LAG.
• Operational Flow Control—Displays the current Flow Control setting.
• Protected LAG—Select to make the LAG a protected port for Layer 2 isolation. See the Port Configuration description in Setting Basic Port Configuration for details regarding protected ports and LAGs.
4. Click Apply. The Running Configuration file is updated.
