TL Port
In translative loop port (TL port) mode, an interface functions as a translative loop port. It may be
connected to one or more private loop devices (NL ports). TL ports are specific to Cisco MDS 9000
Family switches and have similar properties as FL ports. TL ports enable communication between a
private loop device and one of the following devices:
•
•
•
•
TL ports support class 2 and class 3 services.
Private loop devices refer to legacy devices that reside on arbitrated loops. These devices are not aware
of a switch fabric because they only communicate with devices on the same physical loop (see the
"About TL Port ALPA Caches" section on page
We recommend configuring devices attached to TL ports in zones that have up to 64 zone members.
Tip
TL port mode is not supported on Generation 2 switching module interfaces.
Note
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
