Introduction To Ethernet Interfaces; Ethernet Interface Features Supported By The S9300 - Huawei Quidway S9300 Configuration Manual

1 Ethernet Interface Configuration

1.1 Introduction to Ethernet Interfaces

This section describes the Ethernet interfaces.
The Ethernet is flexible, simple, and easy to implement and thus it becomes an important local
area network (LAN) networking technology.
Ethernet interfaces are classified into Ethernet electrical interfaces and Ethernet optical
interfaces.

If the local interface works in auto-negotiation mode, the peer interface must also work in auto-
negotiation mode; otherwise, packet loss may occur.

1.2 Ethernet Interface Features Supported by the S9300

This section describes the Ethernet interface features supported by the S9300.
Interface Group
The interface group function of the S9300 enables you to configure multiple interfaces at the
same time. In the interface group view, you can run commands to configure all the interfaces in
the group.
Auto-Negotiation
During auto-negotiation, the devices on two ends of a physical link can choose the same
operation parameters by exchanging information. The main parameters to be negotiated are
mode (half-duplex or full-duplex), rate, and flow control. After the negotiation is successful, the
devices on two ends operate in the agreed mode and rate.
