Features and Benefits
Flexibility and Scalability
• Software compatibility: Cisco NX-OS interoperates with Cisco products running any variant of the Cisco IOS Software operating system. It also interoperates with any networking OS that conforms to the networking standards listed as supported in this data sheet.
• Common software throughout the data center: Cisco NX-OS simplifies the data center operating environment and provides a unified OS designed to run all areas of the data center network, including storage, virtualization, and Layer 3 network protocols.
• Modular software design: Cisco NX-OS is designed to support distributed multithreaded processing on symmetric multiprocessors (SMPs), multicore CPUs, and distributed line-card processors. Computationally intensive tasks, such as hardware table programming, can be offloaded to dedicated processors distributed across the line cards. Cisco NX-OS modular processes are instantiated on demand, each in a separate protected memory space. Thus, processes are started and system resources allocated only when a feature is enabled. The modular processes are governed by a real-time preemptive scheduler that helps ensure the timely processing of critical functions.
Virtual device contexts (VDCs): Cisco NX-OS offers the capability to segment OS and hardware resources into virtual contexts that emulate virtual devices. Each VDC has its own software processes, dedicated hardware resources (physical interfaces, VLANs, routing table size, Virtual Route Forwarding [VRF], etc.), and independent management environment. VDCs are instrumental in the consolidation of separate networks onto a common infrastructure, maintaining the administrative boundary separation and fault-isolation characteristics of physically separate networks while providing many of the operating cost benefits of a single infrastructure. Each VDC can be restarted without affecting the control, data, or management plane of other VDCs in the system.
Starting with Cisco NX-OS Software Release 6.1, administrator VDC and CPU shares1 are supported. Administrator VDC enables network administrators to configure systemwide settings such as Control Plane Policing (CoPP); VDC creation, suspension, and deletion; and interface allocation. CPU shares provide the capability to configure CPU access and prioritization for each VDC.
• Support for Cisco Nexus fabric extenders: The Cisco Nexus 7000 Series Switch can act as the parent switch for the Cisco Nexus fabric extenders. Because it is a logical extension of its parent switch, the Cisco Nexus fabric extender inherits the functions and benefits offered by the Cisco Nexus 7000 Series Switch. The combination of the Cisco Nexus 2000 Series Fabric Extenders and Cisco Nexus 7000 Series Switches provides the benefits of top-of-rack (ToR) and end-of-row (EoR) network architectures, enabling data centers to scale the number of Gigabit Ethernet access ports, reducing cable runs and management points in the network. Please refer to the list of supported hardware components later in this document to see the Cisco Nexus fabric extenders supported.
• Continuous system operation: Cisco NX-OS provides continuous system operation, permitting maintenance, upgrades, and software certification without service interruption. The combination of process modularity, transparent In-Service Software Upgrade (ISSU) capability, and stateful graceful restart mitigates the effects of software upgrades and other operations.
• Hitless ISSU: Hitless ISSU provides the capability to perform transparent software upgrades on platforms with redundant supervisors, reducing downtime and allowing customers to integrate the newest features and functions with little or no negative effect on network operation.
• Smooth development of enhancements and problem fixes: The modularity of Cisco NX-OS allows new features, enhancements, and problem fixes to be transparently integrated into the software. These updated images can then be installed without disruption using Cisco ISSU.
• Process survivability: Critical processes are run in protected memory space and independently of each other and the kernel, providing detailed service isolation and fault containment and enabling modular patching and upgrading and rapid restartability. Individual processes can be restarted independently without loss of state information and without affecting data forwarding, so that after an upgrade or failure, processes restart in milliseconds without negatively affecting adjacent devices or services. Processes with a large number of states as IP routing protocols are restarted using standards-based nonstop forwarding (NSF) graceful restart mechanisms; other processes use a local persistent storage service (PSS) to maintain their state.
• Stateful supervisor failover: Redundant supervisors are kept synchronized at all times to enable rapid stateful supervisor failover. Sophisticated checks are in place to help ensure that the state is consistent and reliable throughout the entire distributed architecture after failover occurs.
• Reliable interprocess communication: Cisco NX-OS facilitates reliable communication between processes to help ensure that all messages are delivered and properly acted on during failure and adverse conditions. This communication helps ensure process synchronization and state consistency across processes that may be instantiated on processors distributed over multiple supervisors and I/O modules.
• Redundant switched Ethernet out-of-band channels (EOBCs): Cisco NX-OS can make full use of redundant EOBCs for communication between control and I/O module processors.
• Network-based availability: Network convergence is optimized by providing tools and functions to make both failover and fallback transparent and fast. For example, Cisco NX-OS provides Spanning Tree Protocol enhancements such as Bridge Protocol Data Unit (BPDU) guard, loop guard, root guard, BPDU filters, and bridge assurance to help ensure the health of the Spanning Tree Protocol control plane; Unidirectional Link Detection (UDLD) Protocol; NSF graceful restart of routing protocols; millisecond timers for First-Hop Resiliency Protocol (FHRP); Shortest-Path First (SPF) optimizations such as link-state advertisement (LSA) pacing and incremental SPF; IEEE 802.3ad link aggregation with adjustable timers; and Bidirectional Forwarding Detection (BFD).
• Troubleshooting and diagnostics: Cisco NX-OS is built with unique serviceability functions to enable network operators to take early action based on network trends and events, enhancing network planning and improving network operations center (NOC) and vendor response times. Cisco Smart Call Home, Cisco Generic Online Diagnostics (GOLD), and Cisco Embedded Event Manager (EEM) are some of the features that enhance the serviceability of Cisco NX-OS.
• Switched Port Analyzer (SPAN): The SPAN feature allows an administrator to analyze all traffic between ports (called the SPAN source ports) by nonintrusively directing the SPAN session traffic to a SPAN destination port that has an external analyzer attached to it. Encapsulated Remote SPAN (ERSPAN) allows remote monitoring of multiple switches across the network by encapsulating SPAN traffic into a generic routing encapsulation (GRE) tunnel.
• Ethanalyzer: Cisco NX-OS includes a built-in packet analyzer to monitor and troubleshoot control- and data-plane traffic. The packet analyzer is based on the popular Wireshark open source network protocol analyzer.
• IP service-level agreements (SLAs): Cisco NX-OS IP SLAs enable customers to help ensure the service levels of new business-critical IP applications, as well as IP services that use data, voice, and video, in an IP network. Cisco has augmented traditional service-level monitoring and enhanced the IP infrastructure so that it is IP application aware, by measuring services both end to end and at the IP layer. With Cisco NX-OS IP SLAs, users can verify service guarantees, increase network reliability by validating network performance, proactively identify network problems, and increase their return on investment (ROI) by easing the deployment of new IP services. Cisco NX-OS IP SLAs use active monitoring to generate traffic in a continuous, reliable, and predictable manner, thus enabling the measurement of network performance and health.
• Cisco Smart Call Home: The Cisco Smart Call Home feature continuously monitors hardware and software components to provide email-based notification of critical system events. A versatile range of message formats is available for optimal compatibility with pager services, standard email, and XML-based automated parsing applications. The feature offers alert grouping capabilities and customizable destination profiles. It can be used, for example, to directly page a network support engineer, send an email message to a NOC, and employ Cisco AutoNotify services to directly generate a case with the Cisco Technical Assistance Center (TAC). This feature is a step toward autonomous system operation, enabling networking devices to inform IT when a problem occurs and helping ensure that the problem is acted on quickly, reducing time to resolution and increasing system uptime.
• Cisco GOLD: Cisco GOLD is a suite of diagnostic facilities to verify that hardware and internal data paths are operating as designed. Boot-time diagnostics, continuous monitoring, standby fabric loopback tests, and on-demand and scheduled tests are part of the Cisco GOLD feature set. This industry-leading diagnostics subsystem allows rapid fault isolation and continuous system monitoring critical in today's continuously operating environments.
• Cisco EEM: Cisco EEM is a powerful device and system management technology integrated into Cisco NX-OS. Cisco EEM helps customers harness the network intelligence intrinsic to the Cisco software and enables them to customize behavior based on network events as they happen.
• Cisco NetFlow: The Cisco NX-OS implementation of NetFlow supports NetFlow Versions 5 and 9 exports as well as the Flexible NetFlow configuration model. Cisco Nexus 7000 M-Series modules support Full NetFlow and Sampled NetFlow. Cisco Nexus 7000 F2-Series modules will support Sampled NetFlow in NX-OS release 6.1.2. F2 NetFlow sampling rate is greater than 1:8192 so that users have the flexibility to tune the sampling range (flows per second, amount of NetFlow data generated, etc.) based on their NetFlow requirements. In addition to Layer 3 NetFlow, Layer 2 NetFlow is supported across all line cards.
• Programmatic XML interface: Based on the NETCONF industry standard, the Cisco NX-OS XML interface provides a consistent API for devices, enabling rapid development and creation of tools to enhance the network.
• Simple Network Management Protocol (SNMP): Cisco NX-OS complies with SNMPv1, v2c, and v3. A comprehensive collection of MIBs is supported.
• Configuration verification and rollback: With Cisco NX-OS, the system operator can verify the consistency of a configuration and the availability of necessary hardware resources prior to committing the configuration. A device can thus be preconfigured and the verified configuration applied at a later time. Configurations also include checkpoints to allow operators to roll back to a known good configuration as needed.
• Port profiles: Port profiles enable customers to define a policy once and then apply it many times across virtual and physical ports, significantly increasing both efficiency and flexibility in today's virtual data centers.
• Role-based access control (RBAC): With RBAC, Cisco NX-OS enables administrators to limit access to switch operations by assigning roles to users. Administrators can customize access and restrict it to the users who require it. Cisco NX-OS also provides a mechanism to distribute configuration of RBAC roles across devices running Cisco NX-OS for simplified deployment.
• Cisco Data Center Network Manager (DCNM): Cisco DCNM is a management solution dedicated to data center network operations. Cisco DCNM increases the overall data center infrastructure uptime and reliability, thereby enabling business continuity. The solution is designed for the Cisco NX-OS product family.
• Connectivity management processor (CMP) support: Cisco NX-OS supports the use of a CMP for lights-out, remote management of the platform. The CMP aids operations by providing an out-of-band access channel to the Cisco NX-OS console. IPv6 support for the CMP interface is also available, including ping6 and traceroute6.
Traffic Routing, Forwarding, and Management
• Ethernet switching: Cisco NX-OS is built to support high-density, high-performance Ethernet systems, and it provides a complete data center-class Ethernet switch feature set. The feature set includes IEEE 802.1D-2004 Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) (IEEE 802.1w and 802.1s); IEEE 802.1Q VLANs and trunks; QinQ; 16,000-subscriber VLANs; IEEE 802.3ad link aggregation; Link Layer Discovery Protocol (LLDP; IEEE 802.1AB); private VLANs; cross-chassis private VLANs; UDLD in aggressive and standard modes; VLAN Trunking Protocol (VTP) Versions 1 and 2 in client, server, pruning, and transparent modes; and traffic suppression (unicast, multicast, and broadcast). Spanning Tree Protocol enables transparent upgrades using Cisco ISSU in Spanning Tree Protocol environments, BPDU guard, loop guard, root guard, BPDU filters, bridge assurance, and jumbo frame support.
• Cisco Overlay Transport Virtualization (OTV): OTV is a "MAC address in IP" technique for supporting Layer 2 VPNs over any transport, whether it is Layer 2 based or Layer 3 based. By using the principles of MAC address routing, OTV provides an overlay that enables Layer 2 connectivity between separate Layer 2 domains while preserving the fault-isolation benefits of an IP-based interconnection. The core principles on which OTV operates are the use of a control protocol to advertise MAC address reachability information (instead of using data-plane learning) and packet switching of IP encapsulated Layer 2 traffic (instead of using circuit switching). Some of the main benefits achieved with OTV include:
– Zero effect on existing network design: OTV is a transport-agnostic Layer 2 interconnect technology. The configuration is transparent to the sites under consideration.
– Failure isolation: OTV preserves the failure boundary and site independence. OTV does not rely on traffic flooding to propagate reachability information for MAC addresses; instead, a control protocol is used to distribute such information, sites remain independent of each other, and failures do not propagate beyond the OTV edge device.
– Optimized operations: OTV enables single-touch site additions and removals. This feature provides an important operational benefit because the configuration is succinct and uses a single protocol with no add-ons.
– Optimal bandwidth use, resiliency, and scalability: OTV allows multipathing (cross-sectional bandwidth and end-to-end Layer 2 multipathing), transparent multihoming with built-in loop prevention, and multipoint connectivity in an easy-to-manage point-to-cloud model. It does not require the creation of closed tunnels, and the only state maintained is that of a MAC address routing table. The state is distributed and can be programmed in the hardware conditionally to allow the overlay to handle larger numbers of MAC addresses.
– Transparent migration path: Because OTV is agnostic to the core and transparent to the sites, it can be incrementally deployed over any existing topology without altering its network design.
• Ethernet enhancement: The virtual PortChannel (vPC) feature allows one end of a PortChannel to be split across a pair of Cisco Nexus 7000 Series Switches. vPC provides Layer 2 multipathing through the elimination of Spanning Tree Protocol blocked ports in dual-homed connections. vPC enables fully used bisectional bandwidth and simplified Layer 2 logical topologies without the need to change the existing management and deployment models.
• Cisco FabricPath: Cisco FabricPath is a set of multipath Ethernet technologies that combine the reliability and scalability benefits of Layer 3 routing with the flexibility of Layer 2 networks, enabling IT to build massively scalable data centers. Cisco FabricPath offers a topology-based Layer 2 routing mechanism that provides an equal-cost multipath (ECMP) forwarding model. Cisco FabricPath implements an enhancement that solves the MAC address table scalability problem characteristic of switched Layer 2 networks. Furthermore, Cisco FabricPath supports enhanced vPC (vPC+), a technology similar to vPC that allows redundant interconnection of the existing Ethernet infrastructure to Cisco FabricPath without using Spanning Tree Protocol. Benefits introduced by the Cisco FabricPath technology include:
– Operation simplicity: Cisco FabricPath embeds an autodiscovery mechanism that does not require any additional platform configuration. By offering Layer 2 connectivity, the "VLAN anywhere" characteristic simplifies provisioning and offers workload flexibility across the network.
– High resiliency and performance: Because Cisco FabricPath is a Layer 2 routed protocol, it offers stability, scalability, and optimized resiliency along with network failure containment.
– Massively scalable fabric: By building a forwarding model on 16-way ECMP routing, Cisco FabricPath helps prevent bandwidth bottlenecks and allows organizations to add capacity dynamically, without network disruption.
• IP routing: Cisco NX-OS supports a wide range of IPv4 and v6 services and routing protocols. It provides state-of-the-art implementations of the following routing protocols:
– Open Shortest Path First (OSPF) Protocol Versions 2 (IPv4) and 3 (IPv6)
– Intermediate System-to-Intermediate System (IS-IS) Protocol for IPv4 and IPv6
– Border Gateway Protocol (BGP) for IPv4 and IPv6
– Enhanced Interior Gateway Routing Protocol (EIGRP) for IPv4 and IPv6
– Routing Information Protocol Version 2 (RIPv2)
The implementations of these protocols are fully compliant with the latest standards, providing modern enhancements and parameters such as 4-byte autonomous system numbers (ASNs), while shedding unused older functions in favor of a lean implementation that accelerates feature deployment and enhances system stability. NSF graceful restart (NSF-GR) is supported by all unicast protocols. All protocols support all interface types, including Ethernet interfaces, switched virtual interfaces (SVIs) and subinterfaces, PortChannels, tunnel interfaces, and loopback interfaces. The great variety of routing protocols and functions is complemented by a broad collection of IP services, including the following:
– VRF-lite and MPLS VPNs as described in RFCs 2547 and 4364
– Dynamic Host Configuration Protocol (DHCP) Helper
– Unicast Reverse Path Forwarding (uRPF) for IPv4 and IPv6
– Hot-Standby Routing Protocol (HSRP) for IPv4 and IPv6
– Virtual Router Redundancy Protocol (VRRP) for IPv4
– Gateway Load Balancing Protocol (GLBP) for IPv4
– Enhanced object tracking
– Policy-based routing (PBR) for IPv4 and IPv6
– Generic routing encapsulation (GRE) tunneling
– Unicast graceful restart for all protocols in IPv4
– Unicast graceful restart for OSPFv3 in IPv6
• IP Multicast: Cisco NX-OS provides an industry-leading IP Multicast feature set. The Cisco NX-OS implementation lays the foundation for the future development of a comprehensive portfolio of multicast-enabled network functions. In a way similar to its support for the unicast routing protocols, Cisco NX-OS includes state-of-the-art implementations of the following multicast protocols and functions:
– Protocol-Independent Multicast Version 2 (PIMv2)
– Source-Specific Multicast (SSM) for IPv4 and IPv6
– PIM Sparse Mode (Any-Source Multicast [ASM] for IPv4 and IPv6)
– Bidirectional PIM (Bidir PIM) for IPv4 and IPv6
– Anycast Rendezvous Point (Anycast-RP)
– Multicast NSF for IPv4 and v6
– RP-Discovery using bootstrap router (BSR): Auto-RP and static
– Internet Group Management Protocol (IGMP) Versions 1, 2, and 3 router role
– IGMPv2 host mode
– IGMP snooping
– Multicast Listener Discovery (MLD) Protocol Version 2 (for IPv6)
– Multicast Source Discovery Protocol (MSDP) (for IPv4 only)
– IGMP cache on non-disaster recovery for fast convergence
– Policies for multicast configuration (ip pim rp-addr and ip igmp join-group or static-group)
– IGMP group-specific queries to router ports only
– Debug filters for IGMP snooping
• Quality of service (QoS): Cisco NX-OS supports numerous QoS mechanisms, including classification, marking, queuing, policing, and scheduling. Modular QoS CLI (MQC) is supported for all QoS features. MQC can be used to provide uniform configurations across various Cisco platforms.
• Multiprotocol Label Switching (MPLS): Cisco NX-OS supports a comprehensive set of MPLS features including label switching, Layer 3 VPNs, MPLS Traffic Engineering with Fast Reroute (FRR), Multicast VPNs for IPv4, and IPv6 provider edge (6PE) and IPv6 VPN provider edge (6VPE). These features, which interoperate with Cisco IOS Software, provide the foundation for network consolidation and centralization of services and policy control for a securely segmented network fabric, enabling reduced capital expenditures (CapEx) and operating expenses (OpEx) for IT managers.
• Fibre Channel over Ethernet (FCoE): FCoE is a standards-based encapsulation of Fibre Channel frames into Ethernet packets. This technology introduces storage I/O consolidation on top of Ethernet switching fabric in the data centers of the future. FCoE can now be deployed in director-class, highly available, modular platforms for the access layer and core of converged networks. In addition to FCoE hosts and targets support, VE-port support allows FCoE Inter-Switch Links (ISLs) to be formed, creating scalable, multihop FCoE topologies. The FCoE traffic in a Cisco Nexus 7000 Series Switch can be segmented using a dedicated storage VDC, providing an exceptional level of segmentation and isolation of the shared physical infrastructure.
• Location/ID Separation Protocol (LISP): LISP is an evolutionary routing architecture designed for Internet scale and global reach across organizations. The scalability of the routing system and the exhaustion of the IPv4 address space have motivated several proposals based on a common concept: the separation of the locator and identifier in the numbering of Internet devices, often called the Loc/ID split. LISP defines this protocol. The basic idea behind the Loc/ID split is that the current Internet routing and addressing architecture combines two functions: routing locators (RLOCs), which describe how a device is attached to the network, and endpoint identifiers (EIDs), which define "who" the device is, in a single numbering space: the IP address. The advantages include improved scalability of the routing system through greater aggregation of RLOCs. Cisco LISP virtual machine mobility (VM-mobility) is designed to enable global IP endpoint mobility across private networks as well as the Internet to provide a flexible connectivity continuum and enable global cloud computing across organizational boundaries.
• Traffic redirection: Cisco NX-OS supports Web Cache Control Protocol (WCCP) Version 2 in a Layer 2 forwarding mode. WCCP allows the use of cache engines to localize web traffic patterns in the network, enabling content requests to be fulfilled locally. Traffic localization reduces transmission costs and download time. WCCP enables the Cisco Nexus 7000 Series to transparently redirect content requests. The main benefit of transparent redirection is that users need not configure their browsers to use a web proxy. Instead, they can use the target URL to request content and have their requests automatically redirected to a cache engine. WCCP enables a series of cache engines, called a cache engine cluster, to provide content to a router or multiple routers. Clustering cache engines greatly improves the scalability, redundancy, and availability of the caching solution. Clustering of up to 32 cache engines per service group is supported.
• IEEE 1588-2008 (v2) Precision Time Protocol (PTP): IEEE 1588, or PTP, is a time synchronization protocol for nodes distributed across a network. It provides greater accuracy than other time synchronization protocols, such as NTP, because of its hardware time-stamp feature. The Cisco Nexus 7000 F-Series I/O module supports IEEE 1588 PTP in hardware. Pong, a new network monitoring tool that takes advantage of this IEEE 1588 time synchronization infrastructure, is used to diagnose the health of the network. Pong allows measuring of port-to-port delays and is similar to the well-known network monitoring utility ping, but provides a greater depth of network diagnostics.
• Cisco TrustSec® security: As part of the Cisco TrustSec security suite, Cisco NX-OS provides outstanding data confidentiality and integrity, supporting standard IEEE 802.1AE link-layer cryptography with 128-bit Advanced Encryption Standard (AES) cryptography. Link-layer cryptography helps ensure end-to-end data privacy while allowing the insertion of security service devices along the encrypted path. The security group access control list (SGACL), a new network access control model, is based on security group tags instead of IP addresses, enabling implementation of policies that are more concise and easier to manage because of their topology independence.
• Additional network security features: In addition to Cisco TrustSec security, Cisco NX-OS delivers the following security features:
– Data path intrusion detection system (IDS) for protocol-conformance checks
– Message Digest Algorithm 5 (MD5) routing protocol authentication
– Cisco integrated security features, including Dynamic ARP Inspection (DAI), DHCP snooping, and IP source guard
– Authentication, authorization, and accounting (AAA) and TACACS+
– Secure Shell (SSH) Protocol Version 2
– SNMPv3 support
– Port security
– IEEE 802.1x authentication and RADIUS support
– Layer 2 Cisco Network Admission Control (NAC) LAN port IP
– Policies based on MAC addresses and IPv4 and IPv6 addresses supported by named ACLs (port-based ACLs [PACLs], VLAN-based ACLs [VACLs], and router-based ACLs [RACLs])
