The speed 1000 command is only applicable to GigabitEthernet ports.
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.
For ease of management, a Combo port can be categorized into one of the
following two types:
■ Single Combo port: the two Ethernet interfaces in the device panel correspond
to only one interface view, in which state on the two interfaces can be realized.
A single Combo port can be a Layer 2 Ethernet interface or a Layer 3 Ethernet
interface.
■ Dual-Combo port: the two Ethernet interfaces in the device panel correspond
to two interface views. State switchover can be realized in user’s own interfaces
view. A double Combo port can only be a layer 2 Ethernet interface.
n
Currently, only Dual-Combo ports are supported on the Switch 4800G.
Configuring Combo port state
Follow these steps to configure the state for a double Combo port:
