1Before You Start

This document will help you log in to and quickly configure Huawei S series switches.

For more service configurations, see the Switch Configuration Guide.

1Install and power on the switch. For details refer to the S7700 and S9700 Quick

Installation Guide, S12700 Quick Installation Guide, or 2700, S3700, S5700, and

S6700 Series Switches Quick Start Guide.

Telephone number of the agent responsible for your network construction and

service.

Before configuring any data, complete the following tasks:

This document is for switches running V200R003C00 and later.

You can run the display version command in the user view to

check the version of the device.

On small-sized networks, S2700&S3700 switches are deployed at the access layer,

S5700&S6700 switches is deployed at the core layer, and an AR series router

works as the egress router.

The access switches and core switch connect through Eth-Trunk to ensure

reliability.

On an access switch, each department has a VLAN allocated so that services are

separated by VLANs. Configuring a VLANIF interface on the core switch

implements Layer 3 communication between different departments.

The core switch functions as a DHCP server to allocate IP addresses to user

devices on the campus network.

Configuring DHCP snooping on the access switches prevents intranet users from

connecting a small router to the intranet to allocate IP addresses. Configuring IPSG

on the access switches prevents intranet users from changing IP addresses.

This section uses the S2750 as an access switch (ACC1), S5700

as a core switch (CORE), and an AR series router as an egress

router (Router) as examples to demonstrate the configuration

procedure for small-sized campus networks.

Small-Sized Campus Networks

2.1

Before configuring the switches and router, prepare the following data for use in the next

section.

Component Data

Management IP

address 10.10.1.1/24

ACC1: VLAN 10

ACC2: VLAN 20

CORE: VLANs 100,

10, and 20

Configure

interfaces

and VLANs

Port type

Description

The Eth-Trunk works in load balancing or static LACP

mode.

The management IP address is used to log in to

the switch.

The Trunk port

connects to a switch,

and the Access port

connects to a PC.

VLAN1 is the default VLAN on the switch.

To isolate departmentsA and B at Layer 2, add A

to VLAN 10 and B to VLAN 20.

CORE connects to the egress router through

VLANIF100.

This configuration is for Trunk and Access port

setup. If a Hybrid port setupis availableon a

switch, this port can connect to either a host or

another switch.

Management

VLAN VLAN 5

A modular switch‘s management interface is Ethernet0/0/0.

A fixed switch‘s management interface is MEth0/0/1.

For switches without management interfaces, you are

advised to use VLANIF interfaces for inband management.

Configure

Terminals in department B obtain IP addresses

from IP address pool 20.

IP address

CORE connects to the campus egress router

through VLANIF 100 so that the campus intranet

can communicatewith the Internet.

Configure a default route on CORE with the next

hop pointing to the egress router.

After configuring the IP addresses of VLANIF 10

and VLANIF 20 on CORE, departments A and B

can then communicate through CORE.

Public gateway

Description

1.1.1.1/30

The DNS server resolves domain names

into IP addresses.

The public gateway address is the IP

address of the carrier device that connects

to the egress router. Configure a default

route to this IP address on the egress router

to forward intranet traffic to the Internet.

GE1/0/0:

10.10.100.2/24 GE1/0/0 connects the egress router to the

intranet.

2.2

Follow the procedure shown below to configure the switches and router. Once

configurations are complete, user devices within the campus can communicate with

each other, and intranet users can access the Internet.

Step 9 –Save the

configuration.

Step 1 –Log in to

the switch.

Step 2 –Configure

the management IP

address and Telnet.

Step 4 –Configure

DHCP.

Step 5 –Configure

routing of CORE.

Step 3 –Configure

interfaces and

VLANs.

Step 8 –Verify

services.

Step 6 –Configure

the egress router.

Step 7 –Configure

DHCP snooping and

IPSG.

Quickly Configuring Small-Sized Campus

Networks

Logging In to the Switch

Connect your PC to the switch through the console cable provided with the switch.

If your PC does not have a serial port, use a USB to serial cable.

Open the terminal emulation program on your PC. Create a connection and set the

interface and communication parameters.

Select an available port on your PC. For example, if your PC runs a Windows

operating system, you can view port information in Device Manager and select a

port. Table 1 lists the communication parameters on the switch.

If the switch has a Mini USB port, you can connect your PC to the

switch using a Mini USB cable. For this configuration procedure, see

the corresponding Configuration Guide - Basic Configuration based

on the version of the device.

Press Connect until the following information is displayed. Enter your new password,

and then re-enter it to confirm.

Username:admin

Password:

If you log in to the switch for the first time in versions earlier than

V200R010C00, the system asks you to set a login password. In

V200R010C00 and later versions, the default user name for first login is

admin and default password is a[email protected]. You must

change the password after login.

You can now run commands to configure the switch. Enter a question mark (?) after

a command whenever you need help.

Configuring the Management IPAddress and Telnet

After configuring the management IP address of a switch, you can log in to the switch

using this address. CORE is used in the example below to show the procedure of

configuring the management IP address and Telnet.

Configure the management IP address.

<HUAWEI> system-view

[HUAWEI] vlan 5//Create management VLAN 5.

[HUAWEI-VLAN5] management-vlan

[HUAWEI-VLAN5] quit

[HUAWEI] interface vlanif 5

[HUAWEI-vlanif5] ip address 10.10.1.1 24

[HUAWEI-vlanif5] quit

Add the management interface to the management VLAN.

[HUAWEI] interface GigabitEthernet 0/0/8 //Assume that the interface

connected to the NMS is GigabitEthernet 0/0/8.

[HUAWEI-GigabitEthernet0/0/8] port link-type trunk

[HUAWEI-GigabitEthernet0/0/8] port trunk allow-pass vlan 5
