•
For the SFP interface and the RJ-45 Ethernet interface of a combo port, only one interface can be active
at a time. The other one is inactive. By default, the interface with smaller number becomes active.
• To use the inactive interface of a combo port, execute the undo shutdown command to activate the
interface. The other interface of the combo port is then automatically shut down and becomes inactive.
