Next the F_A2 port goes offline, as shown in
Figure 4
on page 15 Example 2 (right), causing
the corresponding Access Gateway N_2 port to be disabled.
The ports mapped to N_2 (F_1, F_3, and F_4) fail over to N_3 and N_4. Note that the F_Ports
are evenly distributed to the remaining online N_Ports and that the F_2 port did not participate
in the failover event.
