Overall flexibility and Scalability • Software package compatibility: Cisco NX-OS interoperates with Cisco solutions working any variant of the Cisco IOS Software program working method. It also interoperates with any networking OS that conforms to the networking specifications outlined as supported in this information sheet. • Common software throughout the facts center: Cisco NX-OS simplifies the facts center functioning atmosphere and supplies a unified OS created to operate all regions of the info middle community, such as storage, virtualization, and Layer three community protocols. • Modular software package layout: Cisco NX-OS is developed to assistance distributed multithreaded processing on symmetric multiprocessors (SMPs), multicore CPUs, and distributed line-card processors. Computationally intensive projects, these kinds of as hardware desk programming, can be offloaded to focused processors distributed throughout the line cards. Cisco NX-OS modular processes are instantiated on need, each and every in a separate guarded memory space. Consequently, processes are started out and method methods allocated only when a characteristic is enabled. The modular processes are ruled by a genuine-time preemptive scheduler that helps make sure the well timed processing of essential capabilities. • Digital system contexts (VDCs): Cisco NX-OS delivers the functionality to section OS and hardware methods into virtual contexts that emulate digital gadgets. Each and every VDC has its personal computer software procedures, dedicated components sources (bodily interfaces, VLANs, routing table dimensions, Virtual Route Forwarding [VRF], and so on.), and impartial conduite setting. VDCs are instrumental in the consolidation of different networks onto a frequent infrastructure, preserving the administrative boundary separation and fault-isolation traits of physically independent networks while offering many of the running charge added benefits of a solitary infrastructure. Every single VDC can be restarted devoid of affecting the manage, knowledge, or conduite plane of other VDCs in the program. • Aid for Cisco Nexus Fabric Extender: The Cisco Nexus 7000 Series Switch can act as the father or mother 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 rational extension of its guardian switch, the Cisco Nexus Fabric Extender inherits the features and rewards offered by the Cisco Nexus 7000 Series. The mixture of the Cisco Nexus 2000 Series Fabric Extenders and Cisco Nexus 7000 Series Switches brings together the added benefits of top rated-of-rack (ToR) and end-of-row (EoR) community architectures, enabling facts facilities to scale the range of Gigabit Ethernet entry ports, reducing cable runs, and decreasing conduite factors in the community. Availability • Continuous system operation: Cisco NX-OS delivers continuous technique operation, permitting upkeep, upgrades, and application certification with no provider interruption. The blend of course of action modularity, hitless In-Service Application Up grade (ISSU) functionality, and stateful graceful restart mitigates the consequences of computer software upgrades and other operations. • Hitless ISSU: Hitless ISSU supplies the ability to perform transparent software program upgrades on platforms with redundant supervisors, reducing downtime and letting clients to integrate the newest attributes and capabilities with very little or no damaging influence on community operation. • Easy development of enhancements and issue fixes: The modularity of Cisco NX-OS allows new attributes, enhancements, and difficulty fixes to be transparently built-in into the software. These updated pictures can then be put in devoid of disruption using Cisco ISSU. • Process survivability: Vital processes are operate in secured memory place and independently of every single other and the kernel, providing specific support isolation and fault containment and enabling modular patching and upgrading and rapid restartability. Personal procedures can be restarted independently without having decline of state facts and devoid of affecting info forwarding, so that following an update or failure, processes restart in milliseconds without negatively impacting adjacent gadgets or companies. Processes with massive quantities of state such as IP routing protocols are restarted working with specifications-based nonstop forwarding (NSF) graceful restart mechanisms other processes use a neighborhood persistent storage support (PSS) to retain their state. • Stateful supervisor failover: Redundant supervisors are stored synchronized at all periods to make it possible for fast stateful supervisor failover. Complex checks are in spot to assist make certain that the state is reliable and trusted in the course of the whole distributed architecture following failover occurs. • Reputable interprocess communication: Cisco NX-OS facilitates reputable communication between processes to support make sure that all messages are sent and effectively acted on through failure and adverse conditions. This communication will help guarantee method synchronization and state consistency across procedures that might be instantiated on processors distributed more than multiple 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 amongst manage and I/O module processors. • Community-based mostly availability: Community convergence is optimized by supplying applications and capabilities to make each failover and fallback clear and rapidly. For example, Cisco NX-OS gives Spanning Tree Protocol enhancements this kind of as Bridge Protocol Info Unit (BPDU) guard, loop guard, root guard, BPDU filters, and bridge assurance to assist make sure the overall health of the Spanning Tree Protocol handle aircraft Unidirectional Hyperlink Detection (UDLD) Protocol NSF swish restart of routing protocols millisecond timers for 1st-Hop Resiliency Protocol (FHRP) Shortest-Route Initially (SPF) optimizations these kinds of as link-state advertisement (LSA) pacing and incremental SPF IEEE 802.3ad backlink aggregation with adjustable timers and Bidirectional Forwarding Detection (BFD). Serviceability • Troubleshooting and diagnostics: Cisco NX-OS is created with one of a kind serviceability functions to help network operators to consider earlier action dependent on network developments and gatherings, improving network organizing and strengthening network operations center (NOC) and vendor response periods. Clever Get in touch with Residence, Cisco Generic Online Diagnostics (GOLD), and Cisco Embedded Occasion Manager (EEM) are some of the attributes that increase the serviceability of Cisco NX-OS. • Switched Port Analyzer (SPAN): The SPAN attribute permits an administrator to review all targeted traffic among ports (called the SPAN resource ports) by nonintrusively directing the SPAN session traffic to a SPAN place port that has an exterior analyzer attached to it. Encapsulated Remote SPAN (ERSPAN) makes it possible for remote monitoring of a number of switches throughout the network by encapsulating SPAN traffic into a generic routing encapsulation (GRE) tunnel. • Ethanalyzer: Cisco NX-OS incorporates a built-in packet analyzer to check and troubleshoot command- and data-aircraft site visitors. The packet analyzer is centered on the common Wireshark open up resource network protocol analyzer. • Sensible Get in touch with Home: The Clever Call Property element continually monitors hardware and software package components to supply e mail-primarily based notification of crucial process activities. A versatile variety of message formats is accessible for optimum compatibility with pager solutions, normal electronic mail, and XML-dependent automated parsing applications. It presents notify grouping abilities and customizable destination profiles. This characteristic can be utilized, for instance, to right page a community support engineer, deliver an e mail concept to a NOC, and utilize Cisco AutoNotify solutions to right create a scenario with the Cisco Technical Help Center (TAC). This feature is a stage towards autonomous technique operation, enabling networking gadgets to inform IT when a issue occurs and serving to make sure that the problem is acted on quickly, minimizing time to resolution and raising technique uptime. • Cisco GOLD: Cisco GOLD is a suite of diagnostic facilities to verify that components and inside information paths are operating as developed. Boot-time diagnostics, steady monitoring, standby fabric loopback assessments, and on-demand and scheduled checks are component of the Cisco GOLD characteristic established. This marketplace-foremost diagnostics subsystem permits fast fault isolation and ongoing program monitoring important in today's repeatedly operating environments. • Cisco EEM: Cisco EEM is a strong gadget and process management know-how built-in into Cisco NX-OS.
