This scenario is illustrated in Figure 252.
Figure 252. Single Operating Mode with Multiple Clients Using the Piggy-
back Feature - Example 2
Because the piggy-back mode is being used and the initial log on to switch
A is accomplished by the supplicant port on switch B, none of the
workstations connected to switch B need to have 802.1x client software
when accessing switch A. The log on to switch A and the subsequent
reauthentications are performed automatically by the supplicant port on
switch B. It should be noted, however, that in this particular scenario the
clients have full access to the resources of switch B even if the switch fails
to log on or reauthenticate to switch A.
The example in the next figure again illustrates two 802.1x-compliant
switches. The difference between this and the previous example is that the
clients in the previous example did not have to log on to access switch B.
In this example the clients have to log on to have any access at all to the
network.
