{{fastethernet | gigabitethernet } slot/interface - interface} [, {vlan vlan_ID - vlan_ID} {{fastethernet | gigabitethernet } slot/interface - interface}] Step 3 可以使用平时的端口配置命令进行配置 退回 验证配置 保存 Step 4 end Step 5 show interfaces [interface-id] Step 6 copy running-config startup-config

当使用interface range命令时有如下的规则:

?

有效的组范围:

o vlan从1 到4094

o fastethernet 槽位/{first port} - {last port} o gigabitethernet槽位/{first port} - {last port}

?

端口号之间需要加入空格，如：interface range fastethernet 2/1 – 5 是有效的，而interface range fastethernet 2/1-5 是无效的.

interface range 命令只能配置已经存在的interface vlan 所有在同一组的端口必须是相同类别的。

? ?

见以下例子:

4006# configure terminal

4006(config)# interface range fastethernet2/1 - 5

4006(config-if-range)# no shutdown

40065(config-if-range)#

*Oct 6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet2/1, changed state to up *Oct 6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet2/2, changed state to up *Oct 6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet2/3, changed state to up *Oct 6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet2/4, changed state to up *Oct 6 08:24:35: %LINK-3-UPDOWN: Interface FastEthernet2/5, changed state to up *Oct 6 08:24:36: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet2/05, changed state to up

*Oct 6 08:24:36: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet2/3, changed state to up

*Oct 6 08:24:36: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet2/4, changed state to up

以下的例子显示使用逗号来配置不同类型端口的组:

4006# configure terminal

4006(config)# interface range fastethernet2/1 – 3， gigabitethernet3/1 - 2

4006(config-if-range)# no shutdown 4006(config-if-range)#

*Oct 6 08:29:28: %LINK-3-UPDOWN: Interface FastEthernet2/1, changed state to up *Oct 6 08:29:28: %LINK-3-UPDOWN: Interface FastEthernet2/2, changed state to up *Oct 6 08:29:28: %LINK-3-UPDOWN: Interface FastEthernet2/3, changed state to up *Oct 6 08:29:28: %LINK-3-UPDOWN: Interface GigabitEthernet3/1, changed state to up *Oct 6 08:29:28: %LINK-3-UPDOWN: Interface GigabitEthernet3/2, changed state to up *Oct 6 08:29:29: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/ 1, changed state to up

*Oct 6 08:29:29: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/ 2, changed state to up

*Oct 6 08:29:29: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/ 3, changed state to up

配置二层端口

4006的所有端口缺省的端口都是二层口，如果此端口已经配置成三层端口的话，则需要用switchport来使其成为二层端口。

配置端口速率及双工模式

可以配置快速以太口的速率为10/100Mbps及千兆以太口的速率为10/100/1000 -Mbps; 但对于GBIC端口则不能配置速率及双工模式，有时可以配置nonegotiate, 当需要联接不支持自适应的其它千兆端口时 命令 目的 Step 1 configure terminal Step 2 interface 进入配置状态. 进入端口配置状态. interface-id Step 3 speed {10 | 100 | 1000 | auto | nonegotiate} 设置端口速率 注 1000 只工作在千兆口. GBIC模块只工作在1000 Mbps下. nonegotiate 只能在这些GBIC上用 1000BASE-SX, -LX, and -ZX GBIC. Step 4 duplex {auto | full | half} Step 5 end Step 6 show interfaces interface-id Step 7 copy running-config startup-config

Switch# configure terminal

Switch(config)# interface fastethernet2/3

Switch(config-if)# speed 10

Switch(config-if)# duplex half

设置全双工或半双工. 退出 显示有关配置情况 保存 端口描述

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
