| Secure Erase |
Beginning with Cisco NX-OS Release 10.2(2)F, Cisco Nexus 3500-XL supports Secure Erase. This feature is introduced to remove all the identifiable customer information on Cisco NX-OS devices in conditions of product removal due to Return Merchandise Authorization (RMA), or upgrade or replacement, or system end-of-life. For more information, see Cisco Nexus 3548 Series NX-OS Security Configuration Guide, Release 10.2(x). |
The enhanced features listed below are existing features introduced in earlier releases but enhanced to support new platforms in Cisco NX-OS Release 10.2(2)F.
| Enhanced Features |
|
| Feature |
Description |
| Multicast Statistics on 3548-XL |
Added support for multicast flow path visibility on Cisco Nexus 3548-XL platform switches. For more information, see Cisco Nexus 3548 Switch NX-OS Multicast Routing Configuration Guide, Release 10.2(x). |
| Bundle OC RPM |
Allows you to enable or disable OpenConfig support on the programmability agents (NETCONF, RESTCONF and gRPC), configure "[no] feature openconfig". For more information, see Cisco Nexus 3500 Series NX-OS Programmability Guide, Release 10.2(x), and Cisco Nexus 3600 Series NX-OS Programmability Guide, Release 10.2(x). |
| 64-bit Migration |
Beginning with Cisco NX-OS Release 10.2(2)F, Cisco N3K-C3548P-XL and Cisco Nexus 3600-R platform switches support Cisco NX-OS 64-bit images. This also means that Cisco NX-OS 32-bit image is not supported on these platform switches anymore. Disruptive upgrade from earlier release to 10.2(2)F 64-bit NX-OS image is supported. For example, upgrade from Cisco NX-OS Release 10.2(1)F (32-bit) to Cisco NX-OS Release 10.2(2)F (which is 64-bit) is a disruptive upgrade. For more information, see Cisco Nexus 3600 Series NX-OS Software Upgrade and Downgrade Guide, Release 10.2(x) . |
Cisco NX-OS Release 10.2(2)F does not include any new hardware for the Cisco Nexus 3000 Series.
