Combo interface
All A3100 v2 switches offer combo interfaces. Each combo interface has one 100/1000Base-X fiber SFP
port and one 10/100/1000Base-T auto-sensing copper Ethernet port. These two ports share one port name
and port view and cannot work simultaneously. When you activate one port (by using the combo enable
{ copper | fiber } command, the other port automatically shuts down. For the number of combo interfaces
available on each A3100 v2 switch, see Table 10, Table 11, and Table 12.
