Thank Beyers for your quick help. I still have some problems.
1 For example, when I want to build a spanning tree among many(more than 2)switches based on Click. How can I generate the BPDU packet? Does the Switch still get the packet from the device and modify it to BPDU frame format and then broadcast the modified packet(BPDU)? I have no clear idea to configure this work. How does the EtherSpanTree element work when switch is building a spanning tree among themselves? When configure a Ethernet Switch, does each switch need an EtherSpanTree element? I have little knowledge on Click and I am totally confused. 2 I still do not know the exact meanings of the parameter in EtherSpanTree. Can anybody give me a detailed discription about this element? For example, in st::EtherSpanTree(00:02:03:04:05:06, in, out, s), Does "00:02:03:04:05:06"represent the MAC address of the switch? Best regards！Looking forward to your reply. I do appreciate your help very much! -Jing 2010-01-18 Jing Yuan 发件人： Beyers Cronje 发送时间： 2010-01-18 01:12:01 收件人： Jing Yuan 抄送： click 主题： Re: [Click] Question about Ethernet Switch Configuration Hi Jing, Look on page 69/70 of http://pdos.csail.mit.edu/papers/click:kohler-phd/thesis.pdf for an explanation and example of a Ethernet Switch configuration that includes EtherSpanTree. There's also an example in click/conf directory called kswitch.ipb Hope that helps.

So should I install Click in some PCs (more than two) and use Click to configure them as switch respectively? 2 My protocol is similar to STP. So I think maybe I can modify the EtherSpanTree element, but there is no description about this element. Does anybody have some experiences or examples about this element or some instances of Ethernet switch which is configured with elements, such as Supperssor, EtherSwitch and EtherSpanTree. I do need some detailed introductions and examples about EtherSpanTree element. Can anybody help me and give me a clear explanation on these questions? Thanks very much! All the best wishes for you!
