Chapter 21 Interface Configuration Overview
This section helps user to learn various kinds of interface that our switch supports and consult configuration
information about different interface types.
For detailed description of all interface commands used in this section, refer to Interface configuration
command. For files of other commands appeared in this section, refer to other parts of the manual.
The introduction includes communication information that can be applied to all interface types.
21.1 Supported Interface Types
For information about interface types, please refer to the following table.
Interface type Task Reference
Ethernet interface
Configures fast Ethernet interface.
Configures gigabit Ethernet
interface.
Configures 10GE Ethernet interface.
Setting the Ethernet Interface
Logical interface
Loopback interface
Null interface
Aggregation interface
VLANinterface
SuperVlan interface
Conifugring Logical Interface
The two supported kinds of interface: Ethernet interface and logical interface. The Ethernet interface type
depends on one device depends on the standard communication interface and the interface card or interfaced
module installed on the switch. The logical interface is the interface without the corresponding physical device,
which is established by user manually.
The supported Ethernet interfaces of our switch include:
Fast Ethernet
Gigabit Ethernet interface
10GE Ethernet interface
The supported logical interface of our switch include:
Loopback interface
Null interface
Aggregation interface
VLANinterface
SuperVlan interface
21.2 Interface Configuration Introduction
The following description applies to the configuration process of all interfaces. Take the following steps to
perform interface configuration in global configuration mode.
(1) At this time, the switch prompt becomes ‘config_’ plus the shortened form of the interface to
be configured. Use these interfaces in terms of their numbers. Numbers are assigned during
installation(exworks) or when an interface card are added to the system. Run the show
