NOTE:
x
A combo interface is a logical interface that comprises one fiber port (Gigabit/100-Mbps SFP port) and
one copper port (10/100/1000Base-T GE port). The two ports share one interface view and cannot
work simultaneously. When you use the
combo enable
{
copper
|
fiber
} command to enable one port,
the other port is disabled automatically.
x
If a port is brought down by the
shutdown
command, use the
undo
shutdown
command to bring up the
interface.
x
After an interface fails, if the switch has an idle interface of the same type, you can plug the cable into
the idle interface.
7.
Check that the speed and duplex settings of the interfaces of a link are the same. Make sure that
two interfaces can work together.
8.
If the failure still exists, contact the local agents or technical support engineers.
