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:
Click Port Management > Link Aggregation > LAG Settings.
Select a LAG, and click Edit.
Enter the values for the following fields:
• 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.
• Operational Status—Displays whether the LAG is currently operating.
• Link Status SNMP Traps—Select to enable generation of SNMP traps
notifying of changes to the link status of the ports in the LAG.
• 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.
