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).
This section lists the following topics:
■ New Hardware Features in Cisco NX-OS Release 7.0(3)I7(6)
■ New Software Features in Cisco NX-OS Release 7.0(3)I7(6)
Cisco NX-OS Release 7.0(3) I7(6) supports the following new hardware:
■ The Cisco Nexus 9736Q-FX line card (N9K-X9736Q-FX) with 1-/10-/40-Gigabit QSFP28 ports.
Cisco NX-OS Release 7.0(3)I7(6) includes the following new software features:
iCAM Features
■ iCAM health monitoring and ITD: support added to provide the following health monitoring data: data on device health and data on ITD service.
For more information, see the Cisco Nexus 9000 Series NX-OS iCAM Configuration Guide, Release 7.x.
Interfaces Features
■ Link Debounce Link-Up: Added support for the link debounce link-up time command on 10G, 25G, 40G and 100G ports on the Cisco Nexus N9K-C9732C-FX, N9K-C9364C, N9K-C9336C-FX2 and N9K-C93240YC-FX2 platform switches and N9K-X97160YC-EX line card.
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 9364C platform switch:
o NXOS-ES-XF2: NX-OS Essentials license package
o NXOS-AD-XF2: NX-OS Advantage license package
o NXOS-NDB: NX-OS NDB add-on license
o N93-LAN1K9-FX2: Enterprise Services Package feature-based license
For more information, see the Cisco NX-OS Licensing Guide.
Label Switching
■ Local label allocation: Added support for IPv4 and IPv6 labeled and unlabeled unicast routes on a single BGP session. This behavior is the same irrespective of whether one or both SAFI-1 and SAFI-4 are enabled on the same session or not.
For more information, see the Cisco Nexus 9000 Series NX-OS Label Switching Configuration Guide, Release 7.x.
Security Features
■ MACsec Configuration: Added support to add, modify and delete the MACsec configuration directly on a port channel member.
For more information, see the Cisco Nexus 9000 Series NX-OS Security Configuration Guide, Release 7.x.
Unicast Routing Features
■ BGP community attribute for specific-routes in an aggregate-route: Supports the ability to suppress certain “more-specific” routes from being advertised to its peers or to decide to advertise the more-specific routes with some community attributes set on them, depending upon the suppress-map route-map configuration.
■ BGP DSCP value - Supports the ability to specify a DSCP value for locally originated packets for IPv4 and IPv6 as part of configuring BGP.
■ BGP routing: the optional keyword [all] was added for the next-hop-self argument. The keyword controls whether reflected routes have their next-hops changed.
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(6)
