Hardware Required
1 Router/Gateway with an 2 Ethernet Adapters
1 Smartbits unit with 2 interface cards
and
2 crossover ethernet cables
or
4 straight ethernet cables and 2 hubs

LAYER 2 SETUP
assign a generic MAC address to SB CardA and place it in the MAC source
field
locate the actual MAC address on Routers A net card and place it in
the MAC dest field
assign a generic MAC address to SB CardB and place it in the MAC source
field
locate the actual MAC address on Routers B net card and place it in
the MAC dest field
LAYER 3 SETUP
assign an IP address to the SB CardA and place it in the IP source field
assign a similar IP address to the SB CardB and place it in the IP
dest field
for the return path
assign the IP address of B in the IP source
assign the IP address of A in the IP dest
OTHER SETUP
Choose the Packet Size you would like to send (Bytes)
Choose the Rate at which you would like to send packets (pps)
do so for both directions
