NOTE:
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). When you enable one port, the other port is disabled
automatically.
If an interface is brought down by the shutdown command, use the undo shutdown command to bring
•
up the interface.
•
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.
Verify that the speed and duplex settings of the interfaces of a link are the same. Make sure two
interfaces can work together.
8.
If the failure persists, contact the local agents or technical support engineers.
