Configuring Ethernet interfaces
Ethernet interface naming conventions
The Ethernet interfaces on the S3600V2 switches are named in the format of
interface-type
A/B/C,
where the following definitions apply:
•
A
—Represents the ID of the switch in an IRF fabric. If the switch is not assigned to any IRF fabric, A
uses 1.
•
B
—Represents a slot number on the switch. It takes 0.
•
C
—Represents the number of an interface on a slot.
Performing general configurations
This section describes the attributes and configurations common to Layer 2 and Layer 3 Ethernet
interfaces.

For more information about the attributes and configuration of Layer 2 Ethernet interfaces, see

Configuring a Layer 2 Ethernet interface
•
For more information about the attributes and configuration of Layer 3 Ethernet interfaces, see
Setting the MTU for a Layer 3 Ethernet interface
Configuring a combo interface
A combo interface is a logical interface that comprises one optical (fiber) port and one electrical (copper)
port. The two ports share one forwarding interface, so they cannot work simultaneously. When you
enable either port, the other port is automatically disabled.
The fiber combo port and the copper combo port share one interface view, in which you can activate the
fiber or copper combo port and configure other port attributes such as the interface rate and duplex
mode.
Configuration prerequisites
Before you configure combo interfaces, complete the following tasks:
•
An S3600V2 switch provides two combo interfaces. The fiber port and copper port of a combo
interface have the same port number. For more information about the combo interface numbers, see
the installation guide of a specific model.
•
Use the
display interface
command to determine which port (fiber or copper) of the combo
interface is active. If the current port is the copper port, the output will include "Media type is
twisted pair, Port hardware type is 1000_BASE_T". If the current port is the fiber port, the output will
not include the information mentioned above. You can also use the
display this
command in the
view of the combo interface to view the combo interface configuration. If the
combo enable fiber
command exists, the fiber port is active; if the command does not exist, the copper fiber is active.
