Flexibility and Scalability • Software package compatibility: Cisco NX-OS interoperates with Cisco items managing any variant of the Cisco IOS Software package running system. It also interoperates with any networking OS that conforms to the networking requirements detailed as supported in this information sheet. • Frequent application through the facts center: Cisco NX-OS simplifies the information center working atmosphere and supplies a unified OS developed to run all places of the facts middle community, such as storage, virtualization, and Layer 3 community protocols. • Modular software style: Cisco NX-OS is made to assist dispersed multithreaded processing on symmetric multiprocessors (SMPs), multicore CPUs, and distributed line-card processors. Computationally intensive duties, such as components desk programming, can be offloaded to dedicated processors distributed throughout the line cards. Cisco NX-OS modular processes are instantiated on desire, every in a different safeguarded memory area. Consequently, procedures are commenced and process resources allocated only when a characteristic is enabled. The modular procedures are governed by a genuine-time preemptive scheduler that assists assure the timely processing of essential functions. • Digital machine contexts (VDCs): Cisco NX-OS gives the capability to segment OS and components means into virtual contexts that emulate virtual units. Each VDC has its personal software processes, committed components methods (physical interfaces, VLANs, routing table dimension, Virtual Route Forwarding [VRF], and so on.), and impartial conduite setting. VDCs are instrumental in the consolidation of separate networks onto a typical infrastructure, sustaining the administrative boundary separation and fault-isolation attributes of physically individual networks while delivering numerous of the working cost added benefits of a one infrastructure. Every single VDC can be restarted without having impacting the handle, info, or management airplane of other VDCs in the process. • Assistance for Cisco Nexus Fabric Extender: The Cisco Nexus 7000 Series Switch can act as the mum or dad switch for the Cisco Nexus 2248TP GE Fabric Extender, the Cisco Nexus 2224TP GE Fabric Extender, and the Cisco Nexus 2232PP 10GE Fabric Extender. Since it is a logical extension of its father or mother switch, the Cisco Nexus Fabric Extender inherits the capabilities and added benefits offered by the Cisco Nexus 7000 Series. The mix of the Cisco Nexus 2000 Series Fabric Extenders and Cisco Nexus 7000 Series Switches brings together the rewards of top rated-of-rack (ToR) and stop-of-row (EoR) community architectures, enabling knowledge facilities to scale the amount of Gigabit Ethernet accessibility ports, cutting down cable runs, and reducing conduite details in the community. Availability • Steady program operation: Cisco NX-OS provides steady process operation, permitting servicing, upgrades, and application certification with no services interruption. The mix of approach modularity, hitless In-Provider Computer software Up grade (ISSU) functionality, and stateful swish restart mitigates the consequences of software program upgrades and other operations. • Hitless ISSU: Hitless ISSU offers the functionality to execute transparent software upgrades on platforms with redundant supervisors, minimizing downtime and letting clients to integrate the latest features and capabilities with little or no adverse influence on community operation. • Clean advancement of enhancements and issue fixes: The modularity of Cisco NX-OS will allow new attributes, enhancements, and problem fixes to be transparently built-in into the software. These up to date images can then be installed without disruption working with Cisco ISSU. • Course of action survivability: Critical processes are operate in guarded memory area and independently of every other and the kernel, providing comprehensive service isolation and fault containment and enabling modular patching and upgrading and quick restartability. Individual processes can be restarted independently with no loss of state info and with out affecting facts forwarding, so that soon after an up grade or failure, processes restart in milliseconds with out negatively impacting adjacent devices or companies. Processes with massive quantities of state these kinds of as IP routing protocols are restarted working with specifications-dependent nonstop forwarding (NSF) sleek restart mechanisms other processes use a nearby persistent storage service (PSS) to retain their state. • Stateful supervisor failover: Redundant supervisors are held synchronized at all occasions to allow swift stateful supervisor failover. Sophisticated checks are in spot to aid assure that the state is steady and trustworthy during the overall distributed architecture right after failover happens. • Dependable interprocess communication: Cisco NX-OS facilitates trusted communication amongst procedures to assist guarantee that all messages are sent and properly acted on in the course of failure and adverse situations. This communication will help ensure procedure synchronization and state consistency across procedures that might be instantiated on processors distributed over several supervisors and I/O modules. • Redundant switched Ethernet out-of-band channels (EOBCs): Cisco NX-OS can make entire use of redundant EOBCs for communication among handle and I/O module processors. • Community-based availability: Community convergence is optimized by supplying resources and functions to make both equally failover and fallback transparent and rapidly. For example, Cisco NX-OS gives Spanning Tree Protocol enhancements such as Bridge Protocol Info Device (BPDU) guard, loop guard, root guard, BPDU filters, and bridge assurance to support make certain the overall health of the Spanning Tree Protocol control plane Unidirectional Hyperlink Detection (UDLD) Protocol NSF swish restart of routing protocols millisecond timers for Initial-Hop Resiliency Protocol (FHRP) Shortest-Path 1st (SPF) optimizations this kind of as backlink-state ad (LSA) pacing and incremental SPF IEEE 802.3ad link aggregation with adjustable timers and Bidirectional Forwarding Detection (BFD). Serviceability • Troubleshooting and diagnostics: Cisco NX-OS is developed with exclusive serviceability functions to make it possible for community operators to require earlier motion based on network developments and occasions, improving network setting up and bettering community operations heart (NOC) and vendor response instances. Sensible Contact House, Cisco Generic On the internet Diagnostics (GOLD), and Cisco Embedded Event Supervisor (EEM) are some of the characteristics that increase the serviceability of Cisco NX-OS. • Switched Port Analyzer (SPAN): The SPAN characteristic will allow an administrator to assess all site visitors amongst ports (identified as the SPAN resource ports) by nonintrusively directing the SPAN session traffic to a SPAN vacation spot port that has an external analyzer hooked up to it. Encapsulated Remote SPAN (ERSPAN) permits remote monitoring of multiple switches across the community by encapsulating SPAN targeted traffic into a generic routing encapsulation (GRE) tunnel. • Ethanalyzer: Cisco NX-OS includes a built-in packet analyzer to keep an eye on and troubleshoot handle- and facts-airplane traffic. The packet analyzer is centered on the preferred Wireshark open up resource community protocol analyzer. • Sensible Contact Household: The Clever Get in touch with Household characteristic continuously screens components and computer software elements to present e-mail-based notification of important process activities. A flexible variety of concept formats is obtainable for optimum compatibility with pager services, regular electronic mail, and XML-centered automatic parsing purposes. It presents notify grouping capabilities and customizable destination profiles. This function can be employed, for example, to straight webpage a network help engineer, ship an e mail message to a NOC, and use Cisco AutoNotify providers to directly make a scenario with the Cisco Technical Aid Center (TAC). This element is a step toward autonomous technique operation, enabling networking products to inform IT when a issue takes place and supporting guarantee that the difficulty is acted on promptly, cutting down time to resolution and growing program uptime. • Cisco GOLD: Cisco GOLD is a suite of diagnostic services to confirm that hardware and inner facts paths are functioning as intended. Boot-time diagnostics, continuous monitoring, standby fabric loopback exams, and on-demand and scheduled exams are part of the Cisco GOLD characteristic set. This sector-top diagnostics subsystem enables speedy fault isolation and continuous program monitoring critical in today's continually functioning environments. • Cisco EEM: Cisco EEM is a potent system and method management technological innovation integrated into Cisco NX-OS.
