Combo interface
A combo interface has one fiber SFP port and one 1000Base-T copper Ethernet port. These two ports
share one port number and cannot work simultaneously. When you activate one port, the other port
automatically shuts down.
On the front panel of an 3600 v2 switch, the copper combo ports are marked in the port number + T
format, and the fiber SFP combo ports are marked in the port number + S format.
