Difference Between Te Ports And Tf-Tnp Ports - Cisco MDS 9000 Series Configuration Manual

Difference Between TE Ports and TF-TNP Ports

• When F port trunking or channeling is configured on a link, the switch cannot be downgraded to Cisco
• If you are upgrading from a SAN-OS Release 3.x to NX-OS Release 5.0(1), and you have not created
If VSAN 4079 is reserved for EVFP use, the switchport trunk allowed vsan command will filter out VSAN
4079 from the allowed list, as shown in the following example:
switch(config-if)# switchport trunk allowed vsan 1-4080
1-4078,4080
• If you have created VSAN 4079, the upgrade to NX-OS Release 5.0(1) will have no affect on VSAN
• If you downgrade after NX-OS Release 5.0(1), the VSAN will no longer be reserved for EVFP use.
Difference Between TE Ports and TF-TNP Ports
In case of TE ports, the VSAN will in be initializing state when VSAN is coming up on that interface and
when peers are in negotiating phase. Once the handshake is done, VSAN will be moved to up state in the
successful case, and isolated state in the case of failure. Device Manager will show the port status as amber
during initializing state and it will be green once VSANs are up.
This example shows the trunk VSAN states of a TE port:
switch# show interface fc2/15
fc2/15 is trunking
In case of TF ports, after the handshake, one of the allowed VSANs will be moved to the up state. All other
VSANs will be in initializing state even though the handshake with the peer is completed and successful.
Each VSAN will be moved from initializing state to up state when a server or target logs in through the trunked
F or NP ports in the corresponding VSAN.
