DynamipsGUI2.8 交换模块试用(Etherchannel)

    今天试用了一下DynamipsGUI 2.8，之前都用的Boson NetSim7.02，总体来说还是相当不错的，不过上星期想做一下Etherchannel的实验时发现Boson没有这些命令......于是就决定去用DynamipsGUI了。

       测试用的是两台3640建立Etherchannel连接，具体怎么使用DynamipsGUI我就不详细说了，大家可以搜一下博客。

      

     

    添加的模块是NW-16ESW，也就是交换模块

 

     

 

      分别连接两台3640的f0/0和f0/1接口

 

 

      之后用SecureCRT分别连接两台路由器，地址为127.0.0.1，端口分别为2001和2002。

   

 

      R1的配置如下：

Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#host
Router(config)#hostname R1

R1(config)#int range fastEthernet 0/0 - 1
R1(config-if-range)#chan
R1(config-if-range)#channel-group 1 mode on
Creating a port-channel interface Port-channel1
R1(config-if-range)#

*Mar  1 00:07:30.327: %LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1, changed state to down
R1(config-if-range)#switch mode trunk
R1(config-if-range)#no shut

*Mar  1 00:08:18.495: %LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1, changed state to up

 

      接下来设置vlan和vtp

R1#vlan data
R1#vlan database

R1(vlan)#vtp server
Device mode already VTP SERVER.
R1(vlan)#vtp domain cisco 
Changing VTP domain name from NULL to cisco
R1(vlan)#vtp password cisco
Setting device VLAN database password to cisco.

R1(vlan)#apply
APPLY completed.
R1(vlan)#vlan 100 name cisco
VLAN 100 added:
    Name: cisco
R1(vlan)#exit
APPLY completed.
Exiting....
R1#

 

      R2配置如下

Router>ena
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#host R2
R2(config)#int ran f0/0 - 1
R2(config-if-range)#chan
R2(config-if-range)#channel-group 1 mode on
Creating a port-channel interface Port-channel1
R2(config-if-range)#

R2(config-if-range)#switch mode trunk

*Mar  1 00:16:16.223: %LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1, changed state to up
R2(config-if-range)#

 

R2#vlan data
R2#vlan database
R2(vlan)#vtp domain cisco
Changing VTP domain name from NULL to cisco
R2(vlan)#vtp pass cisco
Setting device VLAN database password to cisco.

R2(vlan)#vtp client
Setting device to VTP CLIENT mode.

 

      最后show interface portchannel 1和show interface protchannel 1 switchport就可以看到相应的结果：

R1#sh int port-channel 1

      可以看到带宽变成200M了，在R2上show vlan也能看到R1建立了vlan 100：

R2#sh vlan-switch

R2#

 

      好了，总结一下，DynamipsGUI支持交换之后可以做更多的二层实验了，用起来也比Boson舒服多，例如Boson里面show interface switchport是没有提示这条指令的，但你输入完整的话还是有这个功能的，之前做实验时也郁闷了好久......还有关于Etherchannel的，在实际应用中做vtp冗余也不少，不过我觉得与其做冗余，还不如做Etherchannel，提供冗余的同时也能增加带宽，可以绑定2个，4个和8个端口，这样两台6500之间用8个1000M端口绑定Etherchennel就可以提供10Gbit的带宽了，成本也节约不少。

      以后有时间再测试一下DynamipsGUI在BCMSN实验方面的支持如何，要先在实验室了解一下才行=v=
