1.1 Introduction to Ethernet InterfacesThis section describes the Ethernet interfaces. The Ethernet is flexible, simple, and easy to implement; therefore, it becomes an important local area network (LAN) networking technology. Table 1-1 shows the attributes of Ethernet electrical interfaces and Ethernet optical interfaces. Table 1-1 Attributes of Ethernet interfaces Interface Type Rate (Mbit/ s) Auto-negotiation Full Duplex Yes Yes Yes No Yes No Half Duplex Yes Yes No No No No Non-negotiation Full Duplex Yes Yes Yes Yes Yes Yes Half Duplex Yes Yes No No No No

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

1.2 Ethernet Interface Features Supported by the S9300This section describes the Ethernet interface features supported by the S9300.

Port GroupThe port group function enables you to configure multiple interfaces at the same time. You can run commands in the port group view to configure all the interfaces in the group.

Auto-NegotiationThe auto-negotiation function allows interfaces on both ends of a link to select the same operating parameters by exchanging capability information. Each interface sends its capability information to the remote end and checks capabilities of the remote end. After both interfaces receive the capability information from each other, they adopt the highest capability they support to communicate with each other. The interfaces negotiate the duplex mode, speed, and flow control parameters. After a successful negotiation, the interfaces use the same duplex mode, speed, and flow control parameters.Issue 01 (2011-10-26) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 2



Port IsolationThe port isolation function isolates Layer 2 and Layer 3 communication between ports in the same VLAN. This function restricts packet transmission between ports flexibly, providing a secure and flexible network solution.

1.3 Configuring Basic Attributes of the Ethernet InterfaceThis section describes how to configure the description, cable type, duplex mode, rate, and autonegotiation an Ethernet interface, and switch between the optical and electrical interfaces and between Layer 2 and Layer 3 interfaces.

1.3.1 Establishing the Configuration TaskApplicable EnvironmentThe configuration task is applicable to the following situations: l l You can configure the description of interfaces to facilitate the identification, maintenance, and configuration of the interfaces. By default, an FE electrical interface automatically identifies the network cable type. If the interface cannot identify the cable type properly, set the cable type for the interface manually. By default, an FE electrical interface negotiates the duplex mode and rate with the equipment that is directly connected to the interface. If the connected equipment does not have the auto-negotiation capability, set the duplex mode and rate for the FE interface manually so that the interface can work with the connected equipment.

ContextPerform the following steps on the S9300.

ProcedureStep 1 Run:system-view

The system view is displayed. Step 2 Run:interface interface-type interface-number

The interface view is displayed. Step 3 Run:description description

A description is configured for the interface. By default, the description of an interface is "HUAWEI, Quidway Series, X interface". X specifies the interface type and number. ----End

1.3.3 (Optional) Configuring the Cable Type on an InterfaceContextPerform the following steps on the S9300.



The Ethernet electrical interface view is displayed. Step 3 Run:mdi { across | auto | normal }

The cable type is configured for the Ethernet electrical interface. By default, an Ethernet electrical interface automatically identifies the cable type. An electrical interface can use a crossover cable or a straight through cable. If across is specified, the interface can use a crossover cable; if normal is specified, the interface can use a straight through cable; if auto is specified, the interface can use both types of network cables. ----EndIssue 01 (2011-10-26) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 4



1.3.4 (Optional) Setting the Duplex ModeContextDo as follows on the S9300 where you need to set the duplex mode of interfaces.



The Ethernet electrical interface view is displayed. Step 3 Run:undo negotiation auto

The auto-negotiation mode is disabled on the Ethernet electrical interface. Step 4 Run:duplex { full | half }

The duplex mode is set for the Ethernet electrical interface. By default, the duplex mode of an Ethernet electrical interface is full-duplex when autonegotiation is disabled on the interface. ----End

1.3.5 (Optional) Setting the Rate of an InterfaceContextDo as follows on the S9300 where you need to set the rate of interfaces.



The interface view is displayed. Step 3 Run:undo negotiation auto

The auto-negotiation mode is disabled on the interface.Issue 01 (2011-10-26) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 5



Step 4 Run:speed { 10 | 100 | 1000 }

The rate is set for the interface. By default, an Ethernet interface works at its maximum rate when auto-negotiation is disabled on the interface. ----End

1.3.6 (Optional) Enabling Auto-NegotiationContextDo as follows on the S9300 where you want to enable auto-negotiation and on the switch connected to this S9300.



The interface view is displayed. Step 3 Run:negotiation auto

Auto-negotiation is enabled on the interface. By default, an interface works in auto-negotiation mode. The local interface and peer interface must work in the same mode, that is, both in autonegotiation mode or not.NOTE

100M and 10G optical interfaces do not support auto negotiation.

----End

1.3.7 (Optional) Switching Between Optical and Electrical InterfacesContextDo as follows on the S9300 where you need to switch between optical and electrical interfaces.

The system view is displayed. Step 2 Run:interface gigabitethernet interface-number

The GigabitEthernet interface view is displayed. Step 3 Run:combo-port { auto | copper | fiber }

The interface is changed to an optical interface or an electrical interface. By default, a combo port selects the working mode automatically. A G24C LPU has 8 electrical interface and 24 optical interfaces, among which the first 8 optical interfaces are duplexed with electrical interfaces. You can use the combo-port command to use these interfaces as electrical interfaces or optical interfaces. ----End
