1.查看及配置交换机管理地址问题

交换机是目前用于组建局域网的主要设备，交换机根据MAC地址表实现数据帧的转发，通过查看MAC地址表更加有利于交换机工作原理的理解；通过查看CISCO设备邻居信息来了解网络拓扑；通过telnet方式远程访问、配置交换机，这种方式要求此交换机已配置有IP地址。 ●查看交换机MAC地址表 ●查看CISCO设备邻居信息 ●交换机地址配置及默认网关

方案

网络拓扑在这里插入图片描述

步骤一：查看交换机MAC地址表

1）按拓扑配置PC1及PC2的IP地址并查看，如下所示：

PC>ipconfig FastEthernet0 Connection:(default port) Link-local IPv6 Address.........: FE80::2D0:97FF:FED2:2DB0 //PC1的MAC地址 IP Address......................: 192.168.1.1 //PC1的IP地址 Subnet Mask.....................: 255.255.255.0 Default Gateway.................: 0.0.0.0 PC>ipconfig FastEthernet0 Connection:(default port) Link-local IPv6 Address.........: FE80::2D0:BCFF:FE56:AB31 //PC2的MAC地址 IP Address......................: 192.168.1.2 //PC2的IP地址 Subnet Mask.....................: 255.255.255.0 Default Gateway.................: 0.0.0.0

2）PC1通过ping命令测试与PC2的连通性：

PC>ping 192.168.1.2 Pinging 192.168.1.2 with 32 bytes of data: Reply from 192.168.1.2: bytes=32 time=2ms TTL=128 Reply from 192.168.1.2: bytes=32 time=0ms TTL=128 Reply from 192.168.1.2: bytes=32 time=3ms TTL=128 Reply from 192.168.1.2: bytes=32 time=0ms TTL=128 Ping statistics for 192.168.1.2: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 3ms, Average = 1ms

3）查看交换机MAC地址表：

Switch#show mac-address-table Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 1 00d0.97d2.2db0 DYNAMIC Fa0/1 1 00d0.bc56.ab31 DYNAMIC Fa0/2 步骤二：查看CISCO设备邻居信息

1）配置路由器接口IP：

Router>enable Router#configure terminal Router(config)#interface fastEthernet 0/0 Router(config-if)#ip address 192.168.1.254 255.255.255.0 Router(config-if)#no shutdown

2）进入交换机特权模式通过命令查看CISCO设备邻居信息：

Switch#show cdp neighbors Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge S - Switch, H - Host, I - IGMP, r - Repeater, P - Phone Device ID Local Intrfce Holdtme Capability Platform Port ID Router Fas 0/3 179 R C2600 Fas 0/0 步骤三：交换机地址配置及默认网关

1）配置IP地址（192.168.1.10/24）执行“int vlan1”（或interface vlan1）指令进入交换机的vlan1接口配置，再执行“ip add 192.168.1.10 255.255.255.0”配置IP地址（ip add指令相当于ip address），执行“no shutdown”启用此接口，如下所示：

Switch(config)# int vlan1 //进入vlan1接口 Switch(config-if)# ip add 192.168.1.10 255.255.255.0 //配置IP地址 Switch(config-if)# no shutdown //启用接口 %LINK-5-CHANGED: Interface Vlan1, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up

2）进入交换机全局配置模式配置交换机默认网关地址：

Switch#configure terminal Switch(config)#ip default-gateway 192.168.1.254

3）确认当前的运行配置直接执行“end”指令返回特权模式：

Switch(config-if)# end //返回特权模式 Switch# %SYS-5-CONFIG_I: Configured from console by console

4）确认vlan1接口的IP及网关地址信息：

Switch#show running-config Building configuration... Current configuration : 1026 bytes ! version 12.1 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname Switch ! ! ! spanning-tree mode pvst ! 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 192.168.1.10 255.255.255.0 //IP地址与配置一致 ! ip default-gateway 192.168.1.254 //网关地址与配置一致 ! ! ! ! line con 0 ! line vty 0 4 login line vty 5 15 login ! ! end
