1.1 Introduction to Ethernet Interfaces

This 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.

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 S7700

This section describes the Ethernet interface features supported by the S7700.

Port Group

The 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-Negotiation

The 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 (2011-07-15) Huawei Proprietary and Confidential

Quidway S7700 Smart Routing Switch Configuration Guide - Ethernet 1 Ethernet Interface Configuration

Port Isolation

The 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 Interface

1.3.1 Establishing the Configuration Task

Applicable Environment

The configuration task is applicable to the following situations:

l You can configure the description of interfaces to facilitate the identification, maintenance,

and configuration of the interfaces.

l 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.

l 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.

Pre-configuration Tasks

None

1.4 Configuring Advanced Attributes of an Ethernet Interface

1.4.1 Establishing the Configuration Task

Applicable Environment

The configuration task is applicable to the following situations:

l The S7700 provides the interface group function, which enables you to configure multiple

interfaces at the same time.

l If the traffic volume received on an interface of the S7700 may exceed the processing

capability of the interface and the directly connected interface supports traffic control, enable the traffic control function on the interface. When the rate of received traffic reaches the threshold, the interface sends a Pause frame (in full duplex mode) or sends a back pressure signal (in half duplex mode) to notify the peer interface. If the peer interface supports traffic control, it decreases the rate of at which it sends traffic so that the local interface can properly process received traffic.

l Ports enabled with port isolation cannot communicate with each other so that ports on the

same VLAN can be isolated. Port isolation provides secure and flexible networking schemes for customers.

Pre-configuration Tasks

None.

Data Preparation

To configure the advanced functions of Ethernet interfaces, you need the following data.

No.

The system view is displayed.

Step 2 Run:

interface interface-type interface-number

The interface view is displayed.

Step 3 Run:

flow-control

Flow control is enabled on the Ethernet interface.

By default, flow control is disabled on an Ethernet interface.

To implement flow control, you must enable this function on both the local interface and peer interface.

----End

1.4.7 (Optional) Enabling Auto-Negotiation of Flow Control

Context

Do as follows on the S7700 whose interface needs to be configured with auto-negotiation of flow control.

GE interfaces support auto-negotiation of flow control, but FE interfaces do not support this function.

Procedure

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

interface gigabitethernet interface-number

The GE interface view is displayed.

Step 3 Run:

flow-control negotiation

Auto-negotiation of flow control is enabled on the GE interface.

By default, auto-negotiation of flow control is disabled on a GE interface.

You also need to configure auto-negotiation of flow control on the peer interface.

----End

1.4.8 (Optional) Enabling Port Isolation

Issue 01 (2011-07-15) Huawei Proprietary and Confidential

Quidway S7700 Smart Routing Switch Configuration Guide - Ethernet 1 Ethernet Interface Configuration

Context

Do as follows on the S7700 where you need to enable port isolation.

Procedure

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

port-isolate mode { l2 | all }

The port isolation mode is set.

By default, ports are isolated on Layer 2 but can communicate on Layer 3.

Step 3 Run:

interface interface-type interface-number

The Ethernet interface view is displayed.

Step 4 (Optional) Run:

am isolate interface-type interface-number [ to interface-number ]

The Ethernet interface is isolated from another interface unidirectionally.

NOTE

After interface A is isolated from interface B unidirectionally, packets sent by interface A cannot reach interface B, whereas packets sent from interface B can reach interface A.

Step 5 Run:

port-isolate enable [ group group-id ]

Port isolation is enabled.

NOTE

Ports in a port isolation group are isolated from each other, and ports in different port isolation groups can communicate with each other. If group-id is not specified, a port is added to port isolation group 1.

----End

1.4.9 (Optional) Performing a Cable Test on an Interface

Context

A cable test detects faults on the cable connected to an interface. If the cable is working properly, the total length of the cable is displayed. If the cable cannot work properly, the distance between the interface and the fault point is displayed.

Procedure

Step 1 Run:

system-view

Issue 01 (2011-07-15) Huawei Proprietary and Confidential

Quidway S7700 Smart Routing Switch Configuration Guide - Ethernet 1 Ethernet Interface Configuration

The system view is displayed.

Step 2 Run:

interface interface-type interface-number

The interface view is displayed.

Step 3 Run:

virtual-cable-test

A cable test is performed on the interface.

NOTE

l The test result is only for reference.

l Running the virtual-cable-test command may affect services on the interface in a short period of time.

l Before performing a cable test, shut down the remote interface or remove the network cable from the

remote interface. Otherwise, signals from the remote interface may make the test result inaccurate.

----End

1.4.10 (Optional) Assigning an IP Address to an Ethernet Subinterface

Procedure

Step 1 Run:

system-view

The system view is displayed.

Step 2 Run:

interface interface-type interface-number.subinterface-number

An Ethernet sub-interface is created and the Ethernet sub-interface view is displayed.

Step 3 Run:

ip address ip-address { mask | mask-length } [ sub ]

The IP address of the Ethernet sub-interface is configured.

Only the E-series and F-series boards supports the configuration of sub-interfaces.

----End

1.4.11 Checking the Configuration

Procedure

l Run the display port-group [ all | port-group-name ] command to check information about

a port group.

l Run the display interface [ interface-type [ interface-number [.subnumber ] ] ] command

to check information about auto-negotiation capability on an Ethernet interface.
