Cisco 4006交换机（IOS版）简明配置维护手册

命令 目的 Step 1 configure terminal Step 2 interface interface-id Step 3 description string 进入配置模式 进入要加入描述的端口 加入描述 (最多240个字符). 退回. 验证. Step 4 end Step 5 show interfaces interface-id description or show running-config Step 6 copy running-config startup-config

保存 Use the no description interface configuration command to delete the description.

This example shows how to add a description on Fast Ethernet interface 0/4 and to verify the description:

4006# config terminal

Enter configuration commands, one per line. End with CNTL/Z. 4006(config)# interface fastethernet2/4

4006(config-if)# description Connects to Marketing

4006(config-if)# end

4006# show interfaces fastethernet2/4 description

Interface Status Protocol Description

Fa2/4 up down Connects to Marketing

配置三层口

Catalyst 4006支持三种类型的三层端口:

?

SVIs: 即interface vlan

Note 当生成一个interface Vlan时，只有当把某一物理端口分配给它时才

能被激活

? ?

三层以太网通道口（EtherChannel）

.路由口：路由口是指某一物理端口在端口配置状态下用no switchport命令生成的端口

所有的三层都需要IP地址以实现路由交换

配置步骤如下： 命令 目的 Step 1 configure terminal 进入配置状态 进入端口配置状态 把物理端口变成三层口 配置IP地址和掩码 激活端口 Step 2 interface {{fastethernet | gigabitethernet} interface-id} | {vlan vlan-id} | {port-channel port-channel-number} Step 3 no switchport Step 4 ip address ip_address subnet_mask Step 5 no shutdown Step 6 end Step 7 show interfaces [interface-id] show ip interface [interface-id] show running-config interface [interface-id] Step 8 copy running-config startup-config 退出 验证配置 保存配置

配置举例如下：

4006# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. 4006(config)# interface gigabitethernet3/2

4006(config-if)# no switchport

4006(config-if)# ip address 192.20.135.21 255.255.255.0

4006(config-if)# no shutdown

4006(config-if)# end

show ip interface命令:

4006# show ip interface gigabitethernet3/2

GigabitEthernet3/2 is up, line protocol is up Internet address is 192.20.135.21/24 Broadcast address is 255.255.255.255 Address determined by setup command MTU is 1500 bytes

Helper address is not set

Directed broadcast forwarding is disabled

监控及维护端口

监控端口和控制器的状态

主要命令见下表：

Show Commands for Interfaces Command show interfaces [type slot/interface] 目的 显示所有端口或某一端口的状态和配置. 显示一系列端口的状态或错误－关闭的状态 显示二层端口的状态，可以用来决定此口是否为二层或三层口。 显示端口描述 show interfaces interface-id status [err-disabled] show interfaces [interface-id] switchport show interfaces [interface-id] description show protocols [type slot/interface] 显示在任何已配置协议下全局和接口的状态 显示当前配置中的端口配置情况 show running-config interface [interface-id] show version

举例如下:

Switch#show interfaces status

显示软硬件等情况 Port Name Status Vlan Duplex Speed Type Gi1/1 notconnect 1 auto auto No Gbic Gi1/2 notconnect 1 auto auto No Gbic

Gi5/1 notconnect 1 auto auto 10/100/1000-TX Gi5/2 notconnect 1 auto auto 10/100/1000-TX Gi5/3 notconnect 1 auto auto 10/100/1000-TX Gi5/4 notconnect 1 auto auto 10/100/1000-TX
