What is a promiscuous LAN card?
Solution:
This is not actually a specific card, but rather a mode in which many cards can be run. When a driver is set to promiscuous mode, it enables that particular driver to accept/read anything and everything that is passed along the line. This is regardless of frame type, packet size, and so forth It works in the same way that a Lanalyzer works, and is totally different from the concept of binding a lan card to multiple protocols (normally a NIC will notify the software only if it receives a broadcast, or packet, with its node address). A board does not need, require, or even benefit from a promiscuous mode in a multi-protocol environment. The items that the board will be looking for are at the physical layer of the OSI model and are not protocol dependant. Novell requires ODI drivers to support promiscuous mode.

How to test Promiscuous Mode? You can test the mode under NT Server. "Start" -> "Setting" -> "Control Panel" -> "Network" -> "Service" You must add "Monitor Network Tool and Agent" on service of network panel. When you run "Network monitor" --> "Tool" --> "Performance Monitor", the performance monitor will automatically put your card into promiscous mode. You can refer as follow: To start Performance Monitor from Network Monitor On the Tools menu, click Performance Monitor. To start Performance Monitor from Network Monitor On the Tools menu, click Performance Monitor. Notes When you activate Performance Monitor and add Network Monitor counters, Performance Monitor automatically puts your network card into promiscuous mode. Performance Monitor does not take your card out of promiscuous mode until you exit Performance Monitor. Although you can still use your network card while using Performance Monitor, netw
