• Administrative Status—Set the selected LAG to operational (Up) or non-
operational (Down).
• Operational Status—Displays whether the LAG is currently operating.
• Reactivate Suspended LAG—Select to reactivate a port if the LAG has
been disabled through the locked port security option or through the 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 rate 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.
• Neighbor Advertisement—Displays the neighbor LAG (the LAG to which
the selected interface is connected) that advertises its capabilities to the
LAG to start the negotiation process. The possible values are the same as
those listed in the Administrative Advertisement field.
