Figure 14 Network diagram for NPV and Transit switches
The primary responsibilities of Transit switches are filtering and forwarding FCoE protocol packets. They
can recognize and control FCoE packets as compared to standard Ethernet switches. However, they do
not provide FCoE traffic processing capabilities as complex as FCF switches or NPV switches.
