• Reactivate Suspended LAG—Select to reactivate a port if the LAG has 
been disabled through the locked port security option .
• 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.

duplex.
