TE Port

In trunking E port (TE port) mode, an interface functions as a trunking expansion port. It may be
connected to another TE port to create an extended ISL (EISL) between two switches. TE ports are
specific to Cisco MDS 9000 Family switches. They expand the functionality of E ports to support the
following:
•
•
•
In TE port mode, all frames are transmitted in EISL frame format, which contains VSAN information.
Interconnected switches use the VSAN ID to multiplex traffic from one or more VSANs across the same
physical link. This feature is referred to as trunking in the Cisco MDS 9000 Family (see
"Configuring

TF Port

In trunking F port (TF port) mode, an interface functions as a trunking expansion port. It may be
connected to another trunked N port (TN port) or trunked NP port (TNP port) to create a link between a
core switch and an NPV switch or an HBA to carry tagged frames. TF ports are specific to Cisco MDS
9000 Family switches. They expand the functionality of F ports to support VSAN trunking.
In TF port mode, all frames are transmitted in EISL frame format, which contains VSAN information.
Interconnected switches use the VSAN ID to multiplex traffic from one or more VSANs across the same
physical link. This feature is referred to as trunking in the Cisco MDS 9000 Family (see
"Configuring

TNP Port

In trunking NP port (TNP port) mode, an interface functions as a trunking expansion port. It may be
connected to a trunked F port (TF port) to create a link to a core NPIV switch from an NPV switch to
carry tagged frames.

SD Port

In SPAN destination port (SD port) mode, an interface functions as a switched port analyzer (SPAN).
The SPAN feature is specific to switches in the Cisco MDS 9000 Family. It monitors network traffic that
passes though a Fibre Channel interface. This monitoring is done using a standard Fibre Channel
analyzer (or a similar switch probe) that is attached to an SD port. SD ports do not receive frames, they
merely transmit a copy of the source traffic. The SPAN feature is nonintrusive and does not affect
switching of network traffic for any SPAN source ports (see
Using

ST Port

In the SPAN tunnel port (ST port) mode, an interface functions as an entry point port in the source switch
for the RSPAN Fibre Channel tunnel. The ST port mode and the remote SPAN (RSPAN) feature are
specific to switches in the Cisco MDS 9000 Family. When configured in ST port mode, the interface
cannot be attached to any device, and thus cannot be used for normal Fibre Channel traffic (see the
"Configuring SPAN" section on page
