Combo Port Configuration
Introduction to Combo port
A Combo port can operate as either an optical port or an electrical port. Inside the device there is only
one forwarding interface. For a Combo port, the electrical port and the corresponding optical port are
TX-SFP multiplexed. You can specify a Combo port to operate as an electrical port or an optical port.
That is, a Combo port cannot operate as both an electrical port and an optical port simultaneously.
When one is enabled, the other is automatically disabled.

auto-sensing Ethernet ports and two 100/1000Base-X SFP ports on the front panel.
Configuring Combo port state
Follow these steps to configure the state of a Combo port:
To do… Use the command… Remarks
Enter system view

—
Enter Ethernet port view
interface interface-type
interface-number
—
Enable a specified Combo port
undo shutdown
Optional
By default, of the two ports in
a Combo port, the one with a
smaller port ID is enabled.
