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) and later.

Cisco Nexus 95xx

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

Cisco Nexus 7x00

  • Data center spine—NX-OS Release 8.1.(1) and later.
  • 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.

Cisco Nexus 5600
