操作步骤

路由器4设置：

配置CISCO二层交换机的管理IP地址和默认网关

Switch>enable

Switch#conf t

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

Switch(config)#interface vlan 1

Switch(config-if)#ip add 192.168.1.1 255.255.255.0               （设置管理VLAN 1 的IP地址）

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)#exit

Switch(config)#ip default-gateway 192.168.1.254                      （设置交换机默认网关）

Switch(config)#end

 Switch#show interface vlan 1                         （查看VLAN 1 状态）

Vlan1 is up, line protocol is up

  Hardware is CPU Interface, address is 00e0.a3a5.cc4b (bia 00e0.a3a5.cc4b)

  Internet address is 192.168.1.1/24

  MTU 1500 bytes, BW 100000 Kbit, DLY 1000000 usec,

     reliability 255/255, txload 1/255, rxload 1/255

  Encapsulation ARPA, loopback not set

  ARP type: ARPA, ARP Timeout 04:00:00

  Last input 21:40:21, output never, output hang never

  Last clearing of "show interface" counters never

  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

  Queueing strategy: fifo

  Output queue: 0/40 (size/max)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

     1682 packets input, 530955 bytes, 0 no buffer

     Received 0 broadcasts (0 IP multicast)

     0 runts, 0 giants, 0 throttles

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored

     563859 packets output, 0 bytes, 0 underruns

     0 output errors, 23 interface resets

     0 output buffer failures, 0 output buffers swapped out

设置Telnet访问：

Switch>enable

Switch#conf t

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

Switch(config)#line vty 0 4

Switch(config-line)#password VtyPassword

Switch(config-line)#login

Switch(config-line)#exit

 

PC>ipconfig

IP Address......................: 192.168.1.3

Subnet Mask.....................: 255.255.255.0

Default Gateway.................: 0.0.0.0

PC>telnet 192.168.1.1

Trying 192.168.1.1 ...Open

Switch>enable

Switch#conf t

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

Switch(config)#

 

设置端口的速度和三种访问模式

SW1(config)#interface fa0/1

SW1(config-if)#speed {10 | 100 | auto} //10M/100M/自适应 

SW1(config-if)#duplex {auto | full | half} 

 

SW1(config)#int fastEthernet 0/1 

SW1(config-if)#switchport mode access //设置 FA0/1 为 ACCESS 模式 

SW1(config-if)#switchport mode trunk //设置 FA0/1 为 TRUNK 模式 

SW1(config-if)#switchport mode dynamic auto 

//设置 FA0/1 为自动直协商模式(默认) 交换机 TRUNK 端口配置: 1)一般交换机与交换机相连接的端口要设置为 trunk 模式 2 )如果是梳心交换机与非网管的交换机相连,梳心交换机端口设置为 access 模式
