> # 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.

> 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.

> Note In case of TF or TNP ports, the Device Manager will show the port status as amber even after port is up and there is no failure. It will be changed to green once all the VSAN has successful logins.
