如果想监视两个路由器之间的发包情况,网上查到可以用network tap,但搜到的都是国外在卖,想问一下国内哪儿能买到这种network tap呢?谢谢!

最佳答案
network
tap(tap,test access port,测试接入点) ,可以用于capturing OSPF traffic in Wireshark between two
routers,如下图,是抓取路由器和交换机之间的数据包。我主要是想用它来抓取两个路由器之间的数据报,学习OSPF路由协议的交互过程。
我在wireshark论坛中,找到了一个帖子,介绍如何如何买到network tap的,描述如下:
***.***/questions/3413/network-tap
There are a number of vendors that sell those, and I have personally used TAPs from those vendors:
1.
2.
3.
Then there are others, which I haven't tested myself:
1.
2.
and
probably a couple more I haven't even heard of yet. I think most taps just work
fine, I usually use the very basic full duplex taps from Netoptics and Datacom.
经过自己的搜索,找到了两款:
一是ebay上的finisar,***.***/itm/Finisar-UTP-Tap-IL-1-10-100-Network-Tap-New-In-Box-w-power-adapter/192667950714
二是datacomsystems的10/100-AT Network Tap,如下图所示
***.***/products/network-taps/10-100-at-network-tap
商品介绍如下:
The 10/100 Ethernet Tap is a single port device that provides a method to observe traffic on a full duplex Ethernet segment. The 10/100 Ethernet Tap provides easy access to segments while maintaining network integrity. Network performance will not be affected by power loss.
但上面两个都是国外的,不太好买。
总结:想咨询一下国内有没有卖这种network tap的?
