Port configuration and management
This section discusses configuring and managing combo interfaces and transceiver modules.
Configuring a combo interface
A combo interface is a logical interface comprising an SFP port of a transceiver module and an RJ-
45 Ethernet port. The two ports share one forwarding interface, so they cannot work
simultaneously. When you enable either port, the other port is automatically disabled. You can
activate either port as needed.
Configuration prerequisites
Use the display interface interface-type interface-number command to find out which port is an
SFP port and which port is an RJ-45 Ethernet port.
•
If the output includes "Media type is not sure" it means that the port is an SFP port.
For example, the following output shows that GigabitEthernet 5/0/1 is an SFP port.
[Sysname] display interface GigabitEthernet 5/0/1
GigabitEthernet5/0/1 current state: DOWN
Line protocol current state: DOWN
Description: GigabitEthernet5/0/1 Interface
The Maximum Transmit Unit is 1500
Internet protocol processing : disabled
IP Packet Frame Type: PKTFMT_ETHNT_2,
IPv6 Packet Frame Type: PKTFMT_ETHNT_2,
Media type is not sure, loopback not set, promiscuous mode not set
1000M, Full, link type is force link
Output flow-control is disabled, input flow-control is disabled
Last clearing of counters: Never
Last 300 seconds input rate 381.90 bytes/sec, 3048 bits/sec, 2.98 packets/sec
Last 300 seconds output rate 8.79 bytes/sec, 64 bits/sec, 0.14 packets/sec
Input: 4348 packets, 513444 bytes, 0 no buffers
Output:243 packets, 15106 bytes
•
If the output includes "Media type is twisted pair" it means that the interface is an RJ-45
Ethernet port.
For example, the following output shows that GigabitEthernet 5/0/0 is an RJ-45 Ethernet port.
[Sysname] display interface GigabitEthernet 5/0/0
GigabitEthernet5/0/0 current state: DOWN
Line protocol current state: DOWN
