Versatility and Scalability � Application compatibility: Cisco NX-OS interoperates with Cisco products running any variant of the Cisco IOS Software package working technique. It also interoperates with any networking OS that conforms to the networking expectations detailed as supported in this info sheet. � Prevalent application throughout the knowledge middle: Cisco NX-OS simplifies the info middle operating natural environment and delivers a unified OS developed to operate all locations of the data center network, such as storage, virtualization, and Layer three community protocols. � Modular software package design: Cisco NX-OS is developed to help distributed multithreaded processing on symmetric multiprocessors (SMPs), multicore CPUs, and distributed line-card processors. Computationally intensive projects, this sort of as hardware desk programming, can be offloaded to committed processors dispersed across the line cards. Cisco NX-OS modular procedures are instantiated on demand, every in a separate safeguarded memory place. Thus, processes are began and method means allotted only when a attribute is enabled. The modular procedures are ruled by a authentic-time preemptive scheduler that helps make certain the timely processing of essential capabilities. � Virtual gadget contexts (VDCs): Cisco NX-OS gives the functionality to phase OS and components methods into digital contexts that emulate virtual devices. Every VDC has its personal software program processes, focused components means (physical interfaces, VLANs, routing desk dimensions, Virtual Route Forwarding [VRF], and so on.), and unbiased administration setting. VDCs are instrumental in the consolidation of individual networks onto a frequent infrastructure, retaining the administrative boundary separation and fault-isolation qualities of physically independent networks although giving numerous of the running cost added benefits of a one infrastructure. Each VDC can be restarted without impacting the manage, data, or management aircraft of other VDCs in the technique. � 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. Due to the fact it is a logical extension of its parent switch, the Cisco Nexus Fabric Extender inherits the functions and advantages offered by the Cisco Nexus 7000 Series. The mixture of the Cisco Nexus 2000 Series Fabric Extenders and Cisco Nexus 7000 Series Switches moyen the advantages of prime-of-rack (ToR) and end-of-row (EoR) network architectures, enabling data facilities to scale the amount of Gigabit Ethernet accessibility ports, minimizing cable runs, and cutting down administration points in the network. Availability � Ongoing program operation: Cisco NX-OS gives constant program operation, permitting maintenance, upgrades, and software program certification without assistance interruption. The mix of course of action modularity, hitless In-Service Software package Upgrade (ISSU) capability, and stateful graceful restart mitigates the effects of software program upgrades and other functions. � Hitless ISSU: Hitless ISSU delivers the capacity to complete transparent software program upgrades on platforms with redundant supervisors, cutting down downtime and letting prospects to combine the latest functions and capabilities with little or no damaging effect on community operation. � Easy growth of enhancements and challenge fixes: The modularity of Cisco NX-OS permits new capabilities, enhancements, and issue fixes to be transparently built-in into the software program. These up-to-date pictures can then be installed without having disruption making use of Cisco ISSU. � Procedure survivability: Vital procedures are operate in shielded memory space and independently of every single other and the kernel, providing in depth service isolation and fault containment and enabling modular patching and upgrading and speedy restartability. Particular person processes can be restarted independently with out decline of state details and with out impacting info forwarding, so that right after an update or failure, procedures restart in milliseconds with no negatively affecting adjacent products or companies. Procedures with large amounts of state this kind of as IP routing protocols are restarted using expectations-based mostly nonstop forwarding (NSF) sleek restart mechanisms other procedures use a community persistent storage provider (PSS) to maintain their state. � Stateful supervisor failover: Redundant supervisors are kept synchronized at all occasions to permit quick stateful supervisor failover. Sophisticated checks are in spot to assist guarantee that the state is regular and trusted through the total dispersed architecture right after failover happens. � Trusted interprocess communication: Cisco NX-OS facilitates reliable communication amongst procedures to help assure that all messages are delivered and effectively acted on in the course of failure and adverse disorders. This communication assists ensure approach synchronization and state consistency across procedures that may possibly 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 total use of redundant EOBCs for communication in between control and I/O module processors. � Community-based mostly availability: Network convergence is optimized by providing tools and functions to make equally failover and fallback transparent and rapidly. For illustration, Cisco NX-OS gives Spanning Tree Protocol enhancements this kind of as Bridge Protocol Knowledge Unit (BPDU) guard, loop guard, root guard, BPDU filters, and bridge assurance to help assure the wellness of the Spanning Tree Protocol manage plane Unidirectional Backlink Detection (UDLD) Protocol NSF swish restart of routing protocols millisecond timers for Initially-Hop Resiliency Protocol (FHRP) Shortest-Route Initial (SPF) optimizations these kinds of as hyperlink-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 created with exclusive serviceability features to enable network operators to require early action dependent on network tendencies and events, maximizing network setting up and increasing community operations heart (NOC) and vendor reaction moments. Smart Get in touch with Household, Cisco Generic On-line Diagnostics (GOLD), and Cisco Embedded Function Manager (EEM) are some of the capabilities that enrich the serviceability of Cisco NX-OS. � Switched Port Analyzer (SPAN): The SPAN attribute enables an administrator to review all visitors amongst ports (named the SPAN source ports) by nonintrusively directing the SPAN session traffic to a SPAN vacation spot port that has an exterior analyzer hooked up to it. Encapsulated Remote SPAN (ERSPAN) allows remote monitoring of a number of switches across the network by encapsulating SPAN site visitors into a generic routing encapsulation (GRE) tunnel. � Ethanalyzer: Cisco NX-OS includes a designed-in packet analyzer to check and troubleshoot command- and facts-airplane traffic. The packet analyzer is dependent on the popular Wireshark open supply network protocol analyzer. � Wise Phone Household: The Wise Call Home feature continually screens components and software program parts to present e mail-based notification of vital program activities. A adaptable array of message formats is accessible for optimal compatibility with pager companies, normal email, and XML-based automatic parsing applications. It provides alert grouping capabilities and customizable destination profiles. This feature can be employed, for case in point, to directly web page a community aid engineer, send an e mail concept to a NOC, and utilize Cisco AutoNotify companies to directly generate a case with the Cisco Technical Guidance Middle (TAC). This element is a action towards autonomous program operation, enabling networking products to inform IT when a issue happens and helping ensure that the problem is acted on quickly, lowering time to resolution and rising program uptime. � Cisco GOLD: Cisco GOLD is a suite of diagnostic amenities to verify that components and inside information paths are working as developed. Boot-time diagnostics, constant monitoring, standby fabric loopback exams, and on-desire and scheduled assessments are element of the Cisco GOLD attribute established. This industry-top diagnostics subsystem allows swift fault isolation and ongoing technique monitoring vital in today's repeatedly running environments. � Cisco EEM: Cisco EEM is a effective gadget and method management know-how integrated into Cisco NX-OS.
