Cisco® NX-OS Software Release 4.1 continues the design objectives of providing a rich and comprehensive feature set to address the high demands of mission-critical data centers. In addition to support for the new hardware in the Cisco Nexus™ 7000 Series Switches, new software features are also introduced to further enhance Cisco's product offering in the next-generation data center.

Starting with Cisco NX-OS Software Release 4.1, the Cisco Nexus 7000 Series Switches and Cisco MDS 9000 Series Multilayer Switches will be sharing this common operating system that focuses on data center features and protocols, availability, and operational considerations. The first release of Cisco NX-OS Software Release 4.1 for the Cisco Nexus 7000 Series Switch will be named Release 4.1(2).
Table 1 lists the hardware supported in Cisco NX-OS Software Release 4.1, and Table 2 lists the new software features introduced in this release.

Software Feature

Description

Port-Channel Enhancement

Supports configuration of up to 768 Port-Channels

IPv6 Enhancement

Adds support for the following IPv6 protocols:

• Multicast Listener Discovery (MLD) Protocol Version 2
• Bidirectional Protocol Independent Multicast (Bidir PIM)
• Source-Specific Multicast (SSM) PIM
• Enhanced Interior Gateway Routing Protocol (EIGRP)

• Unicast Reverse Path Forwarding (uRPF)
• Quality of Service (QoS)

VLAN Trunking Protocol (VTP) Transparent Mode

Allows VTP protocol data units (PDUs) to pass through Cisco Nexus 7000 Series switches

`show capacity' command

Provides the user with a single command that summarizes the current utilization of the platform hardware resources of the switch

ACL Hardware Resource Pooling

Allows any features that use ACLs to scale beyond 16K entries

Switched Port Analyzer (SPAN) Enhancement

Supports the following options on SPAN destination interfaces:

• Inpkt: Allows the SPAN destination ports to receive the normal incoming traffic
• Learning: Enables MAC addresses learning

Smart CallHome HTTPS Transport

Provides a secure communication channel through the HTTPS tunnel between Cisco Nexus 7000 Series Switches and the Cisco AutoNotify backend server

Role-backed access control (RBAC) Role Distribution

Supports distribution of RBAC role configuration for easier deployment

MIB Enhancement

Adds support for additional MIB:

• IPMCAST-MIB (RFC-5132)

Virtual Port Channel (vPC)

Supported as of r4.1(3)

Increases usable bandwidth by eliminating STP blocked ports in common dual homed designs.

• Transparent to neighbor hosts or switches
• Neighbors need only support LACP
• Retains independent control and data plane
• Support for dual sups per switch

CFSoIP

Cisco Fabric service (CFS) is a distribution protocol that provides a rich set of features, using which applications can distribute and synchronize configuration and/or runtime data in a network.

Ordering Information

Cisco NX-OS is available in three license levels. A rich feature set is provided with the Base license, which is bundled with the hardware at no extra cost. The Enterprise license enables incremental functions that are applicable to many enterprise deployments. The Advanced Services license enables next-generation data-center functions such as virtual device contexts (VDCs) and Cisco TrustSec. Table 3 summarizes the three packages.
