Note
Cisco Nexus 5672 does not interoperate with Cisco Nexus 93xx or 95xx.
The following table lists the software images supported for the different devices.

Table 1 Software Images Supported

Cisco Nexus 93xx

NX-OS Release 7.0(3)I5(1)

Cisco Nexus 95xx

NX-OS Release 7.0(3)I5(1).

Cisco Nexus 7x00

  • Data center spine —NX-OS Release 8.1.(1)
  • Data center interconnect (DCI):
    • VRF Peering mode—NX-OS Release 7.3.1 and later.
    • Integrated DCI mode—NX-OS Release 7.3.1 and later.
