实验一 计算机和交换机基本网络设置

（1） 添加一台华为S3026交换机，添加2台PC

（2） 连接PC1至交换机2号端口，连接PC2至7号端口

（3） 打开PC1的配置界面，配置其IP地址为10.65.1.1(掩码255.255.255.0);

打开PC2的配置界面，配置其IP地址为10.65.1.2(掩码255.255.255.0)

PCA login: root password: linux

[root@PCA root]# ifconfig eth0 192.163.1.1 netmask 255.255.255.0 [root@PCA root]#

PCB login: root password: linux

[root@PCB root]# ifconfig eth0 192.163.1.2 netmask 255.255.255.0 [root@PCB root]#

（4） 更改交换机的名字，为其设置密码，配置远程登录数据

system

Enter system view, return to user view with Ctrl+Z. [Quidway]sysname yiyi [yiyi]super password 123 [yiyi]

（5） 查看默认vlan,也即vlan1

[yiyi]dis vlan

（6） 在PC1上PING测试PC2

[root@PCA root]# ping 192.163.1.2

64 bytes from 192.163.1.1: icmp_seq=1 ttl=128 time=0.207 ms 64 bytes from 192.163.1.1: icmp_seq=1 ttl=128 time=0.100 ms 64 bytes from 192.163.1.1: icmp_seq=1 ttl=128 time=0.96 ms 64 bytes from 192.163.1.1: icmp_seq=1 ttl=128 time=0.96 ms

4packets transmitted, 4 received, 0% loss, time 2000ms

[root@PCA root]#

（7） 在交换机上创建vlan2,将交换机端口3~7加入vlan2，查看vlan

[yiyi]vlan 2

[yiyi-vlan2]port e0/3 to e0/7 [yiyi-vlan2]dis vlan

Vlan Name Status Ports

-------- -------- ---------- ------------------------

2 Vlan02 Active F0/3, F0/4, F0/5, F0/6, F0/7 1002 fddi-d Active 1004 fnet-d Active

VLAN Type SAID MTU -------- ------- -------------- -------- 1 enet 100001 1500 1002 fddi 101002 1500 1002 fnet 101003 1500

[yiyi]

（8） 在PC1上PING测试PC2

[root@PCA root]# ping 192.163.1.2

From 192.163.1.1 icmp_seq=1 Destination Host Unreachable From 192.163.1.1 icmp_seq=1 Destination Host Unreachable From 192.163.1.1 icmp_seq=1 Destination Host Unreachable From 192.163.1.1 icmp_seq=1 Destination Host Unreachable

4packets transmitted, 0 received, 100% loss, time 2000ms

（9） 将交换机端口2加入vlan2,查看vlan [yiyi-vlan2]vlan 2

[yiyi-vlan2]port e0/2 [yiyi-vlan2]dis vlan

Vlan Name Status Ports

-------- -------- ---------- ------------------------

2 Vlan02 Active F0/3, F0/4, F0/5, F0/6, F0/7, F0/2 1002 fddi-d Active 1004 fnet-d Active

VLAN Type SAID MTU -------- ------- -------------- --------

1 enet 100001 1500 1002 fddi 101002 1500 1002 fnet 101003 1500 （10）在PC1上PING测试PC2

[root@PCA root]# ping 192.163.1.2

64 bytes from 192.163.1.1: icmp_seq=1 ttl=128 time=0.207 ms 64 bytes from 192.163.1.1: icmp_seq=1 ttl=128 time=0.100 ms 64 bytes from 192.163.1.1: icmp_seq=1 ttl=128 time=0.96 ms 64 bytes from 192.163.1.1: icmp_seq=1 ttl=128 time=0.96 ms

4packets transmitted, 4 received, 0% loss, time 2000ms

（11）配置vlan2的IP地址为10.65.1.8 255.255.255.0 [yiyi-vlan2]int vlan 2

[yiyi-Vlan-interface2]ip address 192.163.1.6 255.255.255.0 [yiyi-Vlan-interface2]quit

[yiyi]ip route-static 0.0.0.0 0.0.0.0 192.163.1.2 [yiyi]]ip default-gateway 192.163.1.2 [yiyi]save

Save current configuration to flash memory successfully.

（12）在交换机上PING测试PC2

[yiyi]ping 192.163.1.2

From icmp Sequence=0 Destination Host Unreachable From icmp Sequence=1 Destination Host Unreachable From icmp Sequence=2 Destination Host Unreachable From icmp Sequence=3 Destination Host Unreachable From icmp Sequence=4 Destination Host Unreachable --- 192.163.1.2 ping statistics --- 5 packets transmitted 0 packets received 100% packet loss

之所以PING不通，原因可能有：vlan 与vlan 2之间不通，不通过虚拟局域网之间不能直接通信，需要通过路由器。
