思科2960交换机配置方法(CISCO catalyst 2960)

前言:

眼前大家对“cmd密令”大概比较注意,各位老铁们都想要了解一些“cmd密令”的相关内容。那么小编在网摘上收集了一些有关“cmd密令””的相关文章,希望咱们能喜欢,同学们快快来了解一下吧!

连接交换机将交换机配置电缆连接于交换机的通讯配置端口(console口)和计算机的串口(可以直接连接到SCADA服务器后面的串口上)。点击Start(开始) > Programs(程序) > Accessories(附件) > Cojhunications(通讯) > HyperTerminal(超级终端),运行HyperTerminal。在Connection Description对话框中,为这一连接输入一个名称(自己识别方便即可),点击“ok”。在Icon对话框,点击相应的图标并确认。在Connect To对话框,选择正在被使用的串口(一般为COM1口),并确认。在Properties对话框配置端口如下:

Bits per second: 9600

Data Bits: 8

Parity: NONE

Stop bits: 1

Flow control: Xon/Xoff

通讯端口默认为COM1,点击“ok”。

8. 打开交换机电源。

二、配置交换机

在新交换机上电启动后,会出现向导配置模式(若没有请在SWITCH>提示符后输入setup即可启动向导配置模式),在如下部分输入相应的值(粗斜体),并回车。

Would you like to enter the initial configuration dialog? [yes/no]: y

At any point you may enter a question mark '?' for help.

Use ctrl-c to abort configuration dialog at any prompt.

Default settings are in square brackets '[]'.

Basic management setup configures only enough connectivity

for management of the system, extended setup will ask you

to configure each interface on the system

Would you like to enter basic management setup? [yes/no]: y

Configuring global parameters:

2. 为交换机输入一个“host name”,可以自己先任意写一个,要便于识别就行,因为当用TFTP软件恢复之前备份的配置后,hostname也会恢复到原先的设置,在如下部分输入相应的值(粗斜体),并回车,以京海为例:

Enter host name [Switch]: jh_switch01 (京海第一路交换机,即FTE网络A交换机)

The enable secret is a password used to protect access to

privileged EXEC and configuration modes. This password, after

entered, becomes encrypted in the configuration.

Enter enable secret(要求输入特权模式进入密令): *******

The enable password is used when you do not specify an

enable secret password, with some older software versions, and

some boot images.

Enter enable password(要求输入特权模式进入密码): *******

The virtual terminal password is used to protect

access to the router over a network interface.

Enter virtual terminal password: *******

Configure SNMP Network Management? [no]: N

3. 下面是显示信息的一部分,太长没有完全抄录,无需操作,可压空格键完成显示。

Current interface sujhary

Any interface listed with OK? value "NO" does not have a valid configuration

Interface IP-Address OK? Method Status Protocol

Vlan1 unassigned NO unset up down

FastEthernet0/1 unassigned YES unset down down

FastEthernet0/2 unassigned YES unset down down

FastEthernet0/3 unassigned YES unset down down

FastEthernet0/48 unassigned YES unset down down

GigabitEthernet0 unassigned YES unset down down

GigabitEthernet0/2 unassigned YES unset down down

4. 完成以上组态显示后,自动进入交换机对话框,在如下部分输入相应的值(粗体部分),并回车。

Enter interface name used to connect to the

management network from the above interface sujhary: vlan1

Configuring interface vlan1:

Configure IP on this interface? [yes/no]: N

Would you like to enable as a cluster cojhand switch? [yes/no]: N

5. 下面是显示信息的一部分,太长没有完全抄录,无需操作,可压空格键完成显示。

The following configuration cojhand script was created:

hostname jh_switch01

enable secret 5 $1$qF.3$3AIkt0lNtdjMLAdknUnht.

enable password *******

line vty 0 15

password *******123

no snmp-server

!

interface GigabitEthernet0/2

!

end

6. 组态信息显示完后,出现如下对话栏,输入2并回车保存交换机配置信息。

[0] Go to the IOS cojhand prompt without saving this config.

[1] Return back to the setup without saving this config.

[2] Save this configuration to nvram and exit.

Enter your selection [2]: 2

7. 交换机参数配置已完成,具体显示如下:

Building configuration...

[OK]

00:02:36: %LINK-5-CHANGED: Interface Vlan1, changed state to administratively down

00:02:37: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to down

00:02:38: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down

Use the enabled mode 'configure' cojhand to modify this configuration.

接下来需要为交换机设定IP地址。使用enable命令和前面设定的enable密码记入下一步操作,具体操作如下:

Press RETURN to get started!<ENTER>

jh_switch01>enable

Password: *******

8. 为了能使用Telnet必须输入int vlan1(交换机默认所有端口都在vlan1里面),输入相应的值(粗体部分),并回车,具体操作如下。

jh_switch01#config t

Enter configuration cojhands, one per line. End with CNTL/Z.

jh_switch01 (config)#int vlan1

9. 设定IP地址和子网掩码(更具情况确定),具体操作如下:

jh_switch01 (config-if)#ip address IP地址 255.255.255.0

jh_switch01 (config-if)#no shutdown(激活设置)

jh_switch01 (config-if)#exit

jh_switch01 (config)#exit

jh_switch01 #write (将交换机的配置信息保存到nvram存储器中,交换机重启后需要从nvram中加载这个配置)

注:交换机IP地址配置完成后,将交换机接入SCADA网络,在SCADA服务器上用“telnet”命令登录到交换机上,用之前备份配置文件恢复到新的交换机上,以下为具体步骤:

10. 打开服务器上的CMD窗口,输入:“telnet 10.9.0.193”,(以京海站交换机为例),输入密码并进入到特权模式switch#

11. 在特权模式下输入:“copy tftp startup-config” 在以下提示下输入粗体的文字:

Address or name of remote host[]?IP地址 (安装有TFTP软件的服务器地址)

Source filename[]? jh_swh01-confg (之前保存的配置文件名称,名称一定要输入正确)

Destination filename[startup-config]? 按下回车键;

Loading jh_swh01-confg from 10.9.0.193(via vlan1):!!

[OK – 6017bytes]

[OK]

6017 bytes copied in 18.544secs<324bytes/sec>

Switch# reload (重启交换机)

重启完成后,用telnet命令登录到交换机并进入特权模式,输入“show running-config”,查看交换机的配置是否正确。

Switch#show running-config
