Note: FCoE is supported only with FEX models N2K-C2348UPQ, N2K-C2348TQ, N2K-C2232PP, B22-DELL, B22-HP, B22-IBM for N9K-C93180LC-EX, N9K-C93180YC-EX, and N9K-C93180YC-FX switches in ACI Mode.

Unless noted otherwise, NX-OS mode FEX support includes both dual-homed and straight-through support. In ACI mode, dual-homed FEX is not supported. Cisco Nexus 9300 platform switches with -FX2 suffix support only straight-through FEX.
In applications where both the parent switch and the FEX have SFP+ ports, native 10G is supported.
In breakout applications, unless noted otherwise, the QSFP+ connector of the breakout cable attaches to the parent switch and the SFP+ connector(s) attaches to the FEX.
Beginning with Cisco NX-OS Release 7.0(3)I7(3), the Cisco Nexus N9K-C93180YC-FX supports straight-through FEX with N2K-C2232PP and N2K-C2248TP FEX models in NX-OS Mode. Dual-homed FEX is added in Cisco NX-OS Release 9.2(1). FCoE Over FEX is not supported with Nexus N9K-C93180YC-FX in NX-OS Release 7.0(3)I7(3).
Beginning with Cisco NX-OS Release 7.0(3)I7(1), the Cisco Nexus 2332TQ supports the Cisco Nexus 9300, 9300-EX, and 9500 platform switches as the parent switch (on all FEX supported platforms).
Beginning with Cisco NX-OS Release 7.0(3)I7(1), FEX support on breakout ports is added on platforms and ports that support FEX and are breakout capable.
Beginning with Cisco NX-OS Release 7.0(3)I5(1), supported Cisco Nexus 9300 platform switches with -EX suffix support straight-through FEX. Dual-homed FEX is added in Cisco NX-OS Release 7.0(3)I5(2).
The N9K-X9408PC-CFP2 line card does not support the Cisco Nexus 2300 platform FEXs.
First generation Cisco Nexus 9300 platform switches do not support FEXs on uplink module ports (ALE - Application Leaf Engine).
For FEX HIF port channels, we recommend that you enable STP port type edge using the spanning tree port type edge [trunk] command.
The Cisco Nexus 2248PQ, 2348TQ, and 2348UPQ FEXes support connections to the Cisco Nexus 9300 or 9500 platform switches by using supported breakout cables to connect a QSFP+ uplink on the FEX and an SFP+ link on the parent switch (4x10 Gbps links).
Note: For Cisco Nexus 9500 platform switches, 4x10 Gbps breakout for FEX connectivity is supported on N9K-X9432PQ, N9K-X9536PQ, and N9K-X9636PQ beginning with Cisco NX-OS Release 7.0(3)I7(1).
