• If the output includes “Media type is twisted pair, Port hardware type is 1000_BASE_T”, it means
that the port is an RJ-45 Ethernet port. For example, the following output shows that GigabitEthernet
0/2 is an RJ-45 Ethernet port.
[Sysname] display interface GigabitEthernet 0/2
GigabitEthernet0/2 current state: DOWN ( Administratively )
IP Packet Frame Type: PKTFMT_ETHNT_2, Hardware Address: 0000-fc00-7506
Description: GigabitEthernet0/2 Interface
Loopback is not set
Media type is twisted pair
Port hardware type is 1000_BASE_T
Unknown-speed mode, unknown-duplex mode
Link speed type is autonegotiation, link duplex type is autonegotiation
Configuring a combo interface
Follow these steps to configure a combo interface:
To do… Use the command… Remarks
Enter system view system-view —
Enter view of the SFP port or RJ-45
Ethernet port of the combo
interface

—
Activate the RJ-45 Ethernet port or
SFP port
combo enable { copper | fiber } Required
NOTE:
•
A combo interface comprises an SFP port and a RJ-45 Ethernet port. Only one of them can be active at
a time, and the other is inactive. By default, the port with a smaller number is active.
• To use an inactive port of the combo interface, use the undo shutdown command to activate the port.
When the port is activated, the previous active port of the combo interface is automatically shut down
and becomes inactive.
