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 port. 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.
Configuring Combo port state
Follow these steps to configure the state of a Combo port:
To do…
Use the command…

—
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.
In case of a Combo port, only one port (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.
Basic Ethernet Port Configuration
Configuring an Ethernet port
Three types of duplex modes are available to Ethernet ports:
z
Full-duplex mode (full). Ports operating in this mode can send and receive packets simultaneously.
z
Half-duplex mode (half). Ports operating in this mode can either send or receive packets at a given
time.
z
Auto-negotiation mode (auto). Ports operating in this mode determine their duplex mode through
auto-negotiation.
