304 SAN Multiprotocol Routing: An Introduction and Implementation
FC trunking
Trunking, also known as VSAN trunking, enables interconnect ports to transmit
and receive frames in more than one VSAN over the same physical link. In this
case, the link is configured as an extended ISL (EISL) link using the EISL frame
format.
Trunking is only applicable to E_Ports and used for inter-switch connections.
Trunking is normally enabled for all ports in the switch but can be disabled on a
port-by-port basis. If the port becomes operational as a trunking E_Port, it is
referred to as a TE_Port. If a port, with trunking enabled, is connected to a
third-party switch, it works as a normal E_Port.
