Cisco Cisco Agent Desktop 8.5 Guia Da Instalação

The test involves sending sample VLAN packets to a test target NIC card and 
verifying that the packets are not discarded by the pre-processing step, but are 
passed on to the TCP/IP stack on the operating system at the computer hosting the 
NIC card.

The test requires a configuration as shown in the following diagram.

The test target NIC is connected to one port of a simple hub. The hub is connected to 
the network backbone or subnet. You also need a packet generator host capable of 
generating Ethernet traffic. The packet generator host will be connected to another 
port on the hub.

The packet generator host equipment can be either a dedicated packet analyzer or a 
computer with a software-based packet analyzer capable of generating Ethernet 
traffic.

There are a number of software packet analyzers available that can be used for this 
purpose. For a comprehensive list of reliable analyzers, visit the Cooperative 
Association for Internet Data Analysis website at www.caida.org/tools/taxonomy/
workload.xml. The following procedures use the Sniffer Pro packet analyzer.

Once the environment is set up as described above, load the software tools on the 
test target and packet generator host as follows.

Perform the following steps to prepare the test target.

1. Download and install the WinPcap utility. 

2. Create a folder on the test target computer named “VLANTest”.

3. Download WinDump.exe and copy it to the VLANTest folder.
