Feature Impact

Feature Name

Description

Ease of Use

VXLAN GPO: Intra Group Isolation and segmenting within the same host

Beginning with Cisco NX-OS Release 10.6(3)F, you can restrict communication among the endpoints within the same ESG (also known as SG) using intra-ESG isolation feature. This feature minimizes the risk of unauthorized access within ESG and enhances security posture.

For more information, refer to Cisco Nexus 9000 Series NX-OS VXLAN Configuration Guide, Release 10.6(x).

Arp/ND qualification due to enhancement brought in as part of intra-host isolation feature

Beginning with Cisco NX-OS Release 10.6(3)F, support is added for the enhanced proxy ARP or neighbor discovery to allow packets to switch across the ports after configuring Layer 2 isolation.

For more information, refer to Cisco Nexus 9000 Series NX-OS VXLAN Configuration Guide, Release 10.6(x).

VXLAN GPO: SGACL support for ESI multi-homing

Beginning with Cisco NX-OS Release 10.6(3)F, ESI multi homing is support in SGACL. Intra-ESG isolation and ESI multi-homing support in SGACL are mutually exclusive.

For more information, see Cisco Nexus 9000 Series NX-OS VXLAN Configuration Guide, Release 10.6(x).

Regenerate virtual UDI  for cloned Nexus 9300v and 9500v VMs

In previous releases, cloned virtual machines (VM) retained the same virtual UDI (serial number) as the source VM, making it difficult to distinguish between instances. The enhancement provided in NX-OS Release 10.6(3)F introduces an option to regenerate the virtual UDI during cloning, ensuring each cloned VM receives a unique serial number for accurate identification and network traffic management.

For more information, refer to Cisco Nexus 9000v (9300v/9500v) Guide, Release 10.6(x).

[1] For N9K-C9348GC-FXP the PSU SPROM is not readable when the PSU is not connected. The model displays as "UNKNOWN" and status of the module displays as "shutdown."
[2] For specific fan speeds see the Overview section of the Hardware Installation Guide.
[3] This switch runs with +1 redundancy mode so that if one fan fails, the switch can sustain operation. But if a second fan fails, this switch is not designed to sustain operation. Hence before waiting for the major threshold temperature to be hit, the switch will power down due to entering the fan policy trigger command.
