Information About Trunking
Trunking, also known as VSAN trunking, is a feature specific to switches in the Cisco MDS 9000
Family. Trunking enables interconnect ports to transmit and receive frames in more than one VSAN, over
the same physical link. Trunking is supported on E ports and F ports (See
Figure 5-1 and Figure 5-2).
