3COM 的 Monitor Port

最近對Ntop有興趣，研究後再導入公司使用。

目標是供ADSL MODEN用的3Com 4200，3Com 把這塊稱作「Roving Analysis」。Web的管理介面找不到這字眼，Telnet 進去也沒看到…真無奈

去原廠網站翻手冊=>http://support.3com.com/infodeli/tools/switches/ss3/family.htm

有看到這一段：Roving Analysis Setup - This page allows you to set up roving analysis ports for the stack. 4200好像沒有…

在google找到：http://www.directron.com/faq3switches.html

SuperStack 3 Switch 4900, Switch 4060 - Does it support Roving Analysis ?

Problem: Does it support Roving Analysis ?

Fact: SuperStack 3 Switch 4900
Switch 4050
Switch 4060
Roving Analysis
Problem: Unable to find Roving Analysis configuration menus on command line or web interface

Fix: The SuperStack 3 Switch 4900 and Switch 4060 dose NOT support Roving analysis. Note : Roving Analysis allows you to attach a network analyser to an "analysis port" and "monitor port" to monitor network traffic.

好吧，4900都沒有，我4200總不能有吧，再想輒吧
