For more information, see the Cisco Nexus 9000 Series Switch FEX Support page.
■ Cisco Nexus 9300 platform switches do not support FEXs on uplink modules (ALE).
■ Beginning with Cisco NX-OS Release 7.0(3)I7(3), the Cisco Nexus N9K-C93180YC-FX supports N2K-C2232PP and N2K-C2248TP FEX models in NX-OS mode. In this mode, the N9K-C93180YC-FX supports straight-through FEX, but it does not support dual-homed FEX. Active-Active FEX and straight-through FEX are not supported on Cisco N9K-C9348GC-FXP, N9K-C93180TC-FX, N9K-C9336C-FX2, and N9K-C93240YC-FX2 switches in Cisco NX-OS Release 7.0(3)I7(3).

For more information, see the Cisco Nexus 9000 Series NX-OS Fundamentals Configuration Guide, Release 7.x.
Interfaces Features
■ Display FEC information: Added support to display the admin and oper status of FEC interfaces with the show interface fec command.
For more information, see the Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide, Release 7.x.
Licensing Features
■ Introduced the Following licenses for the Cisco Nexus 9300-XF and -GF platform switches:
o ACI-PREMIER-XF: LAN_ENTERPRISE_SERVICES_PKG, NETWORK_SERVICES_PKG, VPN_FABRIC, ACI-ES-XF, NXOS_ESSENTIALS_XF/GF/M4/M8-16 and NXOS_ADVANTAGE_XF/GF/M4/M8-16
o ACI-PREMIER-GF: LAN_ENTERPRISE_SERVICES_PKG, NETWORK_SERVICES_PKG, VPN_FABRIC, ACI-ES-GF, NXOS_ESSENTIALS_XF/GF/M4/M8-16 and NXOS_ADVANTAGE_XF/GF/M4/M8-16
■ Added support for -XF2 Essentials and Advantage license packages priority over -XF packages.
For more information, see the Cisco NX-OS Licensing Guide.
Multicast
■ Consistency Checker — Cisco NX-OS provides consistency checker commands for L2 and L3 Multicast in Cisco Nexus 3500 Series to validate the software state with the hardware state.
For more information, see the Cisco Nexus 9000 Series NX-OS Multicast Routing Configuration Guide, Release 7.x.
Programmability Features
■ Model-Driven Telemetry: On the Cisco Nexus 9000 Series switches, the show telemetry control database sensor-paths command is enhanced to show telemetry details about encoding, collection, transport, and streaming.
Security Features
■ MACsec: Allows CDP/LLDP packets to be dropped when the MACsec configuration on a port with a must-secure policy is disabled..
For more information, see the Cisco Nexus 9000 Series NX-OS Security Configuration Guide, Release 7.x.
Unicast Routing Features
■ P Routing: On the Cisco Nexus 9000 series switches, added the ip pps threshold unicast-forward command that sets the logging conditions for IP packets that the NX-OS software forwards. Also added the show ip pps threshold command, which displays the configured logging conditions.
For more information, see the Cisco Nexus 9000 Series NX-OS Unicast Routing Configuration Guide, Release 7.x.
This section includes the following topics:
■ Resolved Caveats—Cisco NX-OS Release 7.0(3)I7(7)
■ Open Caveats—Cisco NX-OS Release 7.0(3)I7(7)
■ Known Behaviors—Cisco NX-OS Release 7.0(3)I7(7)
NOTE: All caveats listed in this document are those that were reported against the Cisco Nexus 9000 Series switches.
Cisco Nexus 9000 Series, Cisco Nexus 3000 Series, and Cisco Nexus 3500 Series are platforms that run on the unified software and binary. Since some caveats listed against these platforms could be applicable to the Cisco Nexus 3000 series platform too, we recommend that you review the list of caveats in the Release Notes of the other platforms for this release, to see if those are applicable to your network configuration.

To perform a software upgrade or downgrade, follow the instructions in the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide, Release 7.x.
For information about an In Service Software Upgrade (ISSU), see the Cisco NX-OS ISSU Support application.
Note: Upgrading from Cisco NX-OS 7.0(3)I1(2), 7.0(3)I1(3), or 7.0(3)I1(3a) requires installing a patch for Cisco Nexus 9500 platform switches only. For more information on the upgrade patch, see Upgrade Patch Instructions.
This section lists limitations related to Cisco NX-OS Release 7.0(3)I7(7).
