Lost Links
This read-only field shows the number of
times the link has been lost since the Switch was
last reset. If the number in this field is not zero, you
should check your cables and replace any that may
be damaged.
If the port is directly connected to an endstation,
the Lost Links counter increments each time the
endstation goes through a power-off/on cycle.
Intelligent Flow Management
Enable / Disable
This field allows you to enable or disable Intelligent
Flow Management (IFM). IFM minimizes packet loss
which can occur with conventional switches.
IFM should be disabled if the port is connected to a
repeated segment where the traffic is mainly local
to that segment. Refer to “
Server Connections” in
Chapter 1
.
