条件：必须处于同一网段或为ip地址设置子网掩码；设置远程登录密码（步骤2为非必须）

1.配置交换机的管理ip地址并开启端口

Switch(config)#interface vlan 1

Switch(config-if)#ip address 192.168.1.1 255.255.255.0

Switch(config-if)#no shutdown

%LINK-5-CHANGED: Interface Vlan1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up

Switch(config-if)#end

Switch#

2.配置进入特权模式密码

Switch#config t

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#enable password 123456

3.配置telnet远程登录密码

Switch(config)#line vty 0 4

Switch(config-line)#password liuzhen

Switch(config-line)#login

Switch(config-line)#end

Switch#

4.查看配置内容

Switch#show run

Building configuration...

Current configuration : 1003 bytes

no service timestamps debug datetime msec

enable password 123456

interface FastEthernet0/1

interface FastEthernet0/2

interface FastEthernet0/3

interface FastEthernet0/4

interface FastEthernet0/5

interface FastEthernet0/6

interface FastEthernet0/7

interface FastEthernet0/8

interface FastEthernet0/9

interface FastEthernet0/10

interface FastEthernet0/11

interface FastEthernet0/12

interface FastEthernet0/13

interface FastEthernet0/14

interface FastEthernet0/15

interface FastEthernet0/16

interface FastEthernet0/17

interface FastEthernet0/18

interface FastEthernet0/19

interface FastEthernet0/20

interface FastEthernet0/21

interface FastEthernet0/22

interface FastEthernet0/23

interface FastEthernet0/24

interface Vlan1

ip address 192.168.1.1 255.255.255.0

line con 0

line vty 0 4

password liuzhen

line vty 5 15

end

5.配置主机ip地址

6.远程登录时，先输入vty远程登录密码，可进入一般用户模式，再输入进入特权模式密码，进入特权模式。console登录时不用设置vlan的ip地址

补充：

条件中步骤二非必须：必须设置进入特权模式密码才可远程进入特权模式：

Switch>en

% No password set.
