MAC地址表及邻居信息查看

MAC地址表及邻居信息查看

1.1 问题

本例要求为修改计算机名并加入工作组：

1）查看交换机MAC地址表

2）查看CISCO设备邻居信息

1.2 方案

网络拓扑，如图-1所示。

1.3 步骤

实现此案例需要按照如下步骤进行。

步骤一：查看交换机sw1的mac地址表

1）在PC1上ping PC2:192.168.1.2：

1. PC>ipconfig /all
2. FastEthernet0 Connection:(default port)
3. Connection-specific DNS Suffix..:
4. Physical Address................: 00E0.B079.7815
5. Link-local IPv6 Address.........: FE80::2E0:B0FF:FE79:7815
6. IP Address......................: 192.168.1.1
7. Subnet Mask.....................: 255.255.255.0
8. Default Gateway.................: 0.0.0.0
9. DNS Servers.....................: 0.0.0.0
10. DHCP Servers....................: 0.0.0.0
11. DHCPv6 Client DUID..............: 00-01-00-01-E3-E0-53-04-00-E0-B0-79-78-15
13. PC>ping 192.168.1.2
14. Pinging 192.168.1.2 with 32 bytes of data:
15. Reply from 192.168.1.2: bytes=32 time=1ms TTL=128
16. Reply from 192.168.1.2: bytes=32 time=0ms TTL=128
17. Reply from 192.168.1.2: bytes=32 time=1ms TTL=128
18. Reply from 192.168.1.2: bytes=32 time=0ms TTL=128
19. Ping statistics for 192.168.1.2:
20. Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
21. Approximate round trip times in milli-seconds:
22. Minimum = 0ms, Maximum = 1ms, Average = 0ms

2）查看PC2的IP信息

1. PC>ipconfig /all
2. FastEthernet0 Connection:(default port)
3. Connection-specific DNS Suffix..:
4. Physical Address................: 0003.E49E.6445
5. Link-local IPv6 Address.........: FE80::203:E4FF:FE9E:6445
6. IP Address......................: 192.168.1.2
7. Subnet Mask.....................: 255.255.255.0
8. Default Gateway.................: 0.0.0.0
9. DNS Servers.....................: 0.0.0.0
10. DHCP Servers....................: 0.0.0.0
11. DHCPv6 Client DUID..............: 00-01-00-01-DB-A7-C6-5E-00-03-E4-9E-64-45

3）在查看交换机sw1的mac地址表

1. Switch#hostname SW1
2. SW1#show mac-address-table
3. Mac Address Table
4. -------------------------------------------
5. Vlan Mac Address Type Ports
6. ---- ----------- -------- -----
7. 1 0003.e49e.6445 DYNAMIC Fa0/2
8. 1 0010.1148.9309 DYNAMIC Fa0/24
9. 1 00e0.b079.7815 DYNAMIC Fa0/1

步骤二：查看交换机sw1邻居信息

1）更改交换机sw2的主机名

1. Switch>enable
2. SW2#configure terminal
3. SW2(config)#hostname SW2
4. SW2(config)#

2）进入交换机SW1特权模式通过命令查看CISCO设备邻居信息：

1. Switch#show cdp neighbors
2. Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
3. S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone
4. Device ID Local Intrfce Holdtme Capability Platform Port ID
5. SW2 Fas 0/24 174 S 2950 Fas 0/9
