DynamipsGUI2.8 交换模块试用(Etherchannel)
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
今天試用了一下DynamipsGUI 2.8，之前都用的Boson NetSim7.02，總體來說還是相當不錯的，不過上星期想做一下Etherchannel的實驗時發現Boson沒有這些命令......于是就決定去用DynamipsGUI了。 測試用的是兩臺3640建立Etherchannel連接，具體怎么使用DynamipsGUI我就不詳細說了，大家可以搜一下博客。 添加的模塊是NW-16ESW，也就是交換模塊 分別連接兩臺3640的f0/0和f0/1接口 之后用SecureCRT分別連接兩臺路由器，地址為127.0.0.1，端口分別為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

Exiting....
R1# R2配置如下 Router>ena

Router(config)#host R2
R2(config)#int ran f0/0 - 1

R2(config-if-range)# R2#vlan data

R2(vlan)#vtp pass cisco

Setting device to VTP CLIENT mode. 最后show interface portchannel 1和show interface protchannel 1 switchport就可以看到相應的結果： R1#sh int port-channel 1

R2# 好了，總結一下，DynamipsGUI支持交換之后可以做更多的二層實驗了，用起來也比Boson舒服多，例如Boson里面show interface switchport是沒有提示這條指令的，但你輸入完整的話還是有這個功能的，之前做實驗時也郁悶了好久......還有關于Etherchannel的，在實際應用中做vtp冗余也不少，不過我覺得與其做冗余，還不如做Etherchannel，提供冗余的同時也能增加帶寬，可以綁定2個，4個和8個端口，這樣兩臺6500之間用8個1000M端口綁定Etherchennel就可以提供10Gbit的帶寬了，成本也節約不少。 以后有時間再測試一下DynamipsGUI在BCMSN實驗方面的支持如何，要先在實驗室了解一下才行=v=
