Tnp Port - Cisco Nexus 5000 Series Configuration Manual

Configuring Fibre Channel Interfaces
NP Port
When the switch is operating in NPV mode, the interfaces that connect the switch to the core network switch
are configured as NP ports. NP ports operate like N ports that function as proxies for multiple physical N
ports.

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 connect to another Cisco
Nexus device or a Cisco MDS 9000 Family switch. They expand the functionality of E ports to support the
following:
• VSAN trunking
• Fibre Channel trace (fctrace) feature
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 VSAN trunking in the Cisco Nexus device. TE ports support class
3 and class F service.

TF Port
When the switch is operating in NPV mode, the interfaces that connect the switch to the core network switch
are configured as NP ports. NP ports operate like N ports that function as proxies for multiple physical N
ports.
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 expand the functionality of F ports to support
VSAN trunking.
In TF port mode, all frames are transmitted in an 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 VSAN trunking in Cisco Nexus devices. TF ports support class 3
and class F service.

TNP Port

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