Configuring Port Characteristics 479
What is Link Dependency?
The link dependency feature provides the ability to enable or disable one or
more ports based on the link state of one or more different ports. With link
dependency enabled on a port, the link state of that port is dependent on the
link state of another port. For example, if port A is dependent on port B and
the switch detects a link loss on port B, the switch automatically brings down
the link on port A. When the link is restored to port B, the switch
automatically restores the link to port A.
Auto negotiation Enables a port to advertise its transmission rate,
duplex mode and flow control abilities to its
partner.
Speed Specifies the transmission rate for frames.
Duplex mode Specifies whether the interface supports
transmission between the switch and the
connected client in one direction at a time (half)
or both directions simultaneously (both).
Maximum frame size Indicates the maximum frame size that can be
handled by the port.
Flow control This is a global setting that affects all ports. For
