Preparing RFC 2544 for Analysis
24 ETS-1000G
To test the networks which include the devices operating on the data link
layer of the OSI model, for example, a switch, ETS-1000G should be
connected according to the diagram. In this case the traffic being
generated by the device should be redirected back via setting up a
loopback. The source and destination MAC addresses in incoming packets
are swapped and the traffic is sent back to the source port.
To test the networks which include the devices operating on the network
layer of the OSI model, for example, a router, ETS-1000G should be
connected according to the similar diagram as shown on the previous
page. Unlike the previous case, both the source and destination MAC and
IP addresses in incoming packets are swapped and the traffic is sent back
to the source port.
IP 1 An IP address of ETS-1000G.
MAC 2 A MAC address of the remote device which implements traffic
redirection (loopback).
IP 2 An IP address of the remote device which implements traffic
redirection (loopback).
switch A network switch.
router A router.
