MDS 9000 TE Port Channel for Multi-VSAN Trunking with Mismatch Suspension
Short answer
D A TE port (trunking E port) carries multiple VSANs and, with port-channel mode on, suspends a member whose parameters mismatch.
Question
Key Takeaways
A TE port is an EISL that trunks several VSANs; bundling members into a port channel with the default ON mode suspends any member with incompatible operational values (speed, mode, VSAN, allowed VSAN).
Between two MDS 9000 switches, a TE port (trunking E port) in a SAN port channel with ON mode carries multiple VSANs and suspends members whose parameters mismatch.
Common mistake: Picking an F or E port (single VSAN, end-device or non-trunking ISL) or an FT port (NPV link) instead of the TE port needed for multi-VSAN trunking.
Expert Analysis
Why the Answer Is Correct
Between two MDS 9000 switches you need an EISL that carries several VSANs, which is a TE port (trunking E port). When the member interfaces are bundled into a SAN port channel with the default ON mode, the switch moves any member whose operational values (speed, mode, VSAN, allowed VSAN) are incompatible into the suspended state, satisfying the "suspend on mismatch" requirement while load-balancing across the ports.
Why the Other Options Are Wrong
A. FT (TF) ports connect to NPV switches, not to another core switch. B. F ports connect end devices (hosts/storage), not switch-to-switch ISLs. C. E ports are non-trunking expansion ports and carry only a single VSAN, so they cannot meet the "multiple VSANs" requirement.
Community Comment Notes
Votes D 64 / A 27. Arch_Angel (4 likes) states the TE port "moves interfaces to the suspended state if its operational values are incompatible." Rollizo adds that ON mode suspends on mismatch whereas active mode isolates, and a TE port is required to pass several VSANs.

Arch_Angel 👍 4Answer is D Moves interfaces to the suspended state if its operational values are incompatible with the port channel

asd248402 👍 2 Answered APort channel need to be active in order to suspend and the FT is in reality TF port that can be connected to a NPV switch It can 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 a host bus adapter (HBA) in order to carry tagged frames.

Rollizo 👍 2 Answered DD: - Need to pass several VSAN then TE - Port-channel mode ON, because if there is mismatch parameters the port is suspended. (in case active mode, the port is isolated)

Manu_75 👍 1 Answered C- has to be an Edge port between two switches - has to use mode active to detect mismatched parameter Port type TE is not "configured" - there is no "switchport type te" command. It's "switchport type e" and "switchport trunk mode on" that result in a TE port.
