Catalyst 3524

对于Cisco的交换机和路由器来讲,虽然其不同型号的交换机的实现命令上有着很多的相似之处,但是,不同的交换机命令格式的差异却为网络设备的配置带来了一定的不便,因此,本人根据手头的交换机,进行一些基本操作的命令介绍,同时也有具体的配置实例。希望对网友的实际工作和学习有所帮助。同时也很希望有机会与各位网友一起交流探讨!

Catalyst 3524 switch IP 地址的配置

直接进入默认的VLAN 1中进行配置命令如下:

interface VLAN1

ip address 172.16.1.3 255.255.0.0

即可。

在Catalyst 中控制对Telnet的访问

bluestudy_a(config)#Access-list 2 permit 172.16.0.0 0.0.255.255 (定义标准的访问列表)

bluestudy_a(config)#line vty 0 15(进入telnet端口,最多答应16个telnet的会话)

bluestudy_a(config-line)#access-class 2 in(应用上述定义的访问列表,即只有172.16.0.0/16的网段可以实现对交换机的telnet会话

设置交换机的enable 密码

bluestudy_a(config)#enable passWord bluestudy

bluestudy_a(config)#enable secret bluestudy

The enable secret you have chosen is the same as your enable password.

This is not recommended. Re-enter the enable secret.

注:对于如上的密码,secret的优先级更高,优先起作用。

设置console口密码

bluestudy_a(config)#line con 0

bluestudy_a(config-line)#password bluestudy

bluestudy_a(config-line)#

设置对telnet的密码:

bluestudy_a(config)#line vty 0 15

bluestudy_a(config-line)#login

bluestudy_a(config-line)#password bluestudy

bluestudy_a(config-line)#

设置登陆用户名和密码:

bluestudy_a(config)#username bluestudy password bluestudy

bluestudy_a(config)#

bluestudy_a#show running

Current configuration:

!

version 12.0

no service pad

service timestamps debug uptime

service timestamps log uptime

no service password-encryption

!

hostname bluestudy_a

!

enable secret 5 $1$b1mb$p6XgV/PY9WqvJy9MrHZFG/

enable password bluestudy

!

username bluestudy password 0 bluestudy

!

ip subnet-zero

!

interface FastEthernet0/1

!

interface FastEthernet0/2

!

interface FastEthernet0/3

!

interface FastEthernet0/4

!

interface FastEthernet0/5

!

interface FastEthernet0/6

!

interface FastEthernet0/24

!

interface GigabitEthernet0/1

!

interface GigabitEthernet0/2

!

interface VLAN1

ip address 172.16.1.3 255.255.0.0

no ip directed-broadcast

no ip route-cache

!

access-list 2 permit 172.16.0.0 0.0.255.255

!

line con 0

password bluestudy

transport input none

stopbits 1

line vty 0 4

access-class 2 in

password bluestudy

login

line vty 5 15

access-class 2 in

password bluestudy

login

!

end

bluestudy_a#

port channel 与 Spanning tree连接的区别

bluestudy_a(config)#interface fastEthernet 0/1

bluestudy_a(config-if)#port group 2

bluestudy_a(config-if)#

bluestudy_a(config)#interface fastEthernet 0/2

bluestudy_a(config-if)#port group 2

bluestudy_a(config-if)#

bluestudy_b(config)#interface fastEthernet 0/23

bluestudy_b(config-if)#port group 2

bluestudy_b(config-if)#

bluestudy_b(config)#interface fastEthernet 0/24

bluestudy_b(config-if)#port group 2

bluestudy_a(config-if)#

这时在bluestudy_a与bluestudy_b之间连接的两条双较线的端口灯均是绿色,表示二者传输数据正常。

现在我将双方之间的channel配置去掉

bluestudy_a(config)#interface fastEthernet 0/1

bluestudy_a(config-if)#no port group 2

bluestudy_a(config-if)#

bluestudy_a(config)#interface fastEthernet 0/2

bluestudy_a(config-if)#no port group 2

bluestudy_a(config-if)#

bluestudy_b(config)#interface fastEthernet 0/23

bluestudy_b(config-if)#no port group 2

bluestudy_b(config-if)#

bluestudy_b(config)#interface fastEthernet 0/24

bluestudy_b(config-if)#no port group 2

bluestudy_a(config-if)#

然后打开Spanning tree

bluestudy_a(config)#spanning-tree vlan 1

bluestudy_a(config)#

bluestudy_b(config)#spanning-tree vlan 1

bluestudy_b(config)#

在交换机b上查看Spanning tree状态

bluestudy_b#show spanning-tree vlan 1

Spanning tree 1 is executing the IEEE compatible Spanning Tree protocol

Bridge Identifier has priority 32768, address 0006.d74f.6700

Configured hello time 2, max age 20, forward delay 15

Current root has priority 32768, address 0006.5329.cd80

Root port is 13, cost of root path is 19

Topology change flag not set, detected flag not set, changes 30

Times: hold 1, topology change 35, notification 2

hello 2, max age 20, forward delay 15

Timers: hello 0, topology change 0, notification 0

Interface Fa0/1 (port 13) in Spanning tree 1 is FORWARDING

Port path cost 19, Port priority 128

Designated root has priority 32768, address 0006.5329.cd80

Designated bridge has priority 32768, address 0006.5329.cd80

Designated port is 37, path cost 0

Timers: message age 1, forward delay 0, hold 0

BPDU: sent 2, received 358

Interface Fa0/2 (port 14) in Spanning tree 1 is BLOCKING

Port path cost 19, Port priority 128

Designated root has priority 32768, address 0006.5329.cd80

Designated bridge has priority 32768, address 0006.5329.cd80

Designated port is 38, path cost 0

Timers: message age 0, forward delay 0, hold 0

BPDU: sent 1, received 351

Interface Fa0/3 (port 15) in Spanning tree 1 is down

Port path cost 100, Port priority 128

Designated root has priority 32768, address 0006.5329.cd80

Designated bridge has priority 32768, address 0006.d74f.6700

Designated port is 15, path cost 19

Timers: message age 0, forward delay 0, hold 0

BPDU: sent 1, received 0

在交换机a上查看Spanning tree状态

bluestudy_b#show spanning-tree vlan 1

Interface Fa0/23 (port 37) in Spanning tree 1 is FORWARDING

Port path cost 19, Port priority 128

Designated root has priority 150, address 0006.d74f.6700

Designated bridge has priority 150, address 0006.d74f.6700

Designated port is 13, path cost 0

Timers: message age 4, forward delay 0, hold 0

BPDU: sent 453, received 119

Interface Fa0/24 (port 38) in Spanning tree 1 is BLOCKING

Port path cost 19, Port priority 128

Designated root has priority 150, address 0006.d74f.6700

Designated bridge has priority 150, address 0006.d74f.6700

Designated port is 14, path cost 0

Timers: message age 3, forward delay 0, hold 0

BPDU: sent 440, received 118

结果如上:一根通一根断

对堆叠端口同样进行trunk封装

bluestudy_a#config t

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

bluestudy_a(config)#interface gigabitEthernet 0/1(此端口为堆叠端口)

bluestudy_a(config-if)#switchport mode trunk

bluestudy_a(config-if)#

bluestudy_b(config)#interface gigabitEthernet 0/1(此端口为堆叠端口)

bluestudy_b(config-if)#switchport mode trunk

bluestudy_b(config-if)#

bluestudy_c(config)#interface gigabitEthernet 0/2(此端口为堆叠端口)

bluestudy_c(config-if)#switchport mode trunk

bluestudy_c(config-if)#

bluestudy_d(config)#interface gigabitEthernet 0/2(此端口为堆叠端口)

bluestudy_d(config-if)#switchport mode trunk

bluestudy_d(config-if)#

bluestudy_e(config)#interface gigabitEthernet 0/2(此端口为堆叠端口)

bluestudy_e(config-if)#switchport mode trunk

bluestudy_e(config-if)#

对上述5台交换机相应的堆叠端口进行VLAN trunk的封装以后,各个交换机上的属于同一vlan的端口之间就可以进行完整的通讯了

在交换机bluestudy_e上定义同样的vlan 10 和20

将配有同一子网IP的PC分别连接在属于VLAN 10 或20的端口之上,即可互相连通。

bluestudy(vlan)#vlan 10 name bluestudy_10

VLAN 10 added:

Name: bluestudy_10

bluestudy(vlan)#vlan 20 name bluestudy_20

VLAN 20 added:

Name: bluestudy_20

bluestudy(vlan)#exit

APPLY completed.

Exiting....

bluestudy#

注:对于同一交换机上可以设置多个不同子网中的IP地址,但是在同一时刻只有一个IP(即一个VLAN IP)是处于激活状态的

Catalyst 3524的高级配置

VLAN的设置:

首先要进入VLAN的设置模式,有别于 5500等第三层交换机

bluestudy_a#vlan database

bluestudy_a(vlan)#

命令集如下:

bluestudy_a(vlan)#?

VLAN database editing buffer manipulation commands:

abort Exit mode without applying the changes

apply Apply current changes and bump revision number

exit Apply changes, bump revision number, and exit mode

no Negate a command or set its defaults

reset Abandon current changes and reread current database

show Show database information

vlan Add, delete, or modify values associated with a single VLAN

vtp Perform VTP administrative functions.

bluestudy_a(vlan)#

bluestudy_a(vlan)#vlan 10 name bluestudy_10

VLAN 10 added:

Name: bluestudy_10

bluestudy_a(vlan)#

bluestudy_a(vlan)#vlan 20 name bluestudy_20

VLAN 20 added:

Name: bluestudy_20

bluestudy_a(vlan)#
