Combo Port Configuration
Introduction to Combo ports
A Combo port comprises an optical (fiber) port or an electrical (copper) port. The two ports share one
forwarding interface and thus they cannot work at the same time. If the electrical port is enabled, the
optical port is disabled automatically and vice versa.
Configuring Combo port state
Follow these steps to configure the state of a double Combo port:
To do…
Use the command…

Combo port
undo shutdown
Optional
By default, of the two ports in a
Combo port, the one with a
smaller port ID is enabled.
In case of a Combo port, only one interface (either the optical port or the electrical port) is active at a
time. That is, once the optical port is active, the electrical port will be inactive automatically, and vice
versa.
Management Ethernet Interface Configuration
Introduction to management Ethernet interface
A management Ethernet interface also uses an RJ-45 connector. It can be used to connect a
background PC for software loading and system debugging, or connect to a remote device, for example,
a remote network management station, for remote system management. It has the attributes of a
common Ethernet interface, but because it is located on the main board, it provides much faster
