Versatility and Scalability • Computer software compatibility: Cisco NX-OS interoperates with Cisco products managing any variant of the Cisco IOS Software operating process. It also interoperates with any networking OS that conforms to the networking specifications detailed as supported in this information sheet. • Typical software all through the information heart: Cisco NX-OS simplifies the data center running natural environment and supplies a unified OS made to run all places of the knowledge center network, together with storage, virtualization, and Layer 3 community protocols. • Modular software design: Cisco NX-OS is designed to assist distributed multithreaded processing on symmetric multiprocessors (SMPs), multicore CPUs, and distributed line-card processors. Computationally intensive jobs, such as components table programming, can be offloaded to committed processors dispersed throughout the line cards. Cisco NX-OS modular procedures are instantiated on demand, each and every in a individual guarded memory house. Therefore, procedures are began and process sources allocated only when a attribute is enabled. The modular processes are governed by a genuine-time preemptive scheduler that can help guarantee the timely processing of important capabilities. • Digital gadget contexts (VDCs): Cisco NX-OS provides the ability to segment OS and components assets into digital contexts that emulate digital units. Every VDC has its own software processes, devoted hardware assets (bodily interfaces, VLANs, routing desk measurement, Digital Route Forwarding [VRF], etcetera.), and independent conduite surroundings. VDCs are instrumental in the consolidation of independent networks onto a prevalent infrastructure, keeping the administrative boundary separation and fault-isolation attributes of bodily independent networks although delivering many of the working cost advantages of a single infrastructure. Each VDC can be restarted devoid of impacting the command, knowledge, or management plane of other VDCs in the process. • Assist for Cisco Nexus Fabric Extender: The Cisco Nexus 7000 Series Switch can act as the mother or father 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 mother or father switch, the Cisco Nexus Fabric Extender inherits the capabilities and advantages presented by the Cisco Nexus 7000 Series. The mix of the Cisco Nexus 2000 Series Fabric Extenders and Cisco Nexus 7000 Series Switches moyen the added benefits of leading-of-rack (ToR) and conclusion-of-row (EoR) community architectures, enabling facts facilities to scale the quantity of Gigabit Ethernet entry ports, decreasing cable runs, and minimizing administration details in the community. Availability • Constant process operation: Cisco NX-OS offers ongoing system operation, permitting maintenance, upgrades, and application certification with out assistance interruption. The mix of approach modularity, hitless In-Provider Software package Up grade (ISSU) ability, and stateful sleek restart mitigates the outcomes of software program upgrades and other functions. • Hitless ISSU: Hitless ISSU offers the functionality to perform clear software program upgrades on platforms with redundant supervisors, decreasing downtime and letting prospects to combine the newest features and functions with tiny or no detrimental result on network operation. • Clean development of enhancements and challenge fixes: The modularity of Cisco NX-OS enables new capabilities, enhancements, and challenge fixes to be transparently integrated into the software. These up to date images can then be installed with out disruption using Cisco ISSU. • Course of action survivability: Critical procedures are run in secured memory place and independently of each other and the kernel, supplying detailed assistance isolation and fault containment and enabling modular patching and upgrading and speedy restartability. Individual processes can be restarted independently with out loss of state facts and without having affecting facts forwarding, so that following an update or failure, procedures restart in milliseconds with out negatively impacting adjacent devices or expert services. Processes with large quantities of state this kind of as IP routing protocols are restarted utilizing requirements-dependent nonstop forwarding (NSF) sleek restart mechanisms other procedures use a community persistent storage services (PSS) to keep their state. • Stateful supervisor failover: Redundant supervisors are held synchronized at all times to allow rapid stateful supervisor failover. Advanced checks are in location to aid ensure that the state is regular and reputable all through the entire dispersed architecture soon after failover occurs. • Reliable interprocess communication: Cisco NX-OS facilitates reputable communication between procedures to help make certain that all messages are sent and effectively acted on through failure and adverse circumstances. This communication will help make certain process synchronization and state consistency across procedures that may possibly be instantiated on processors distributed above a number of supervisors and I/O modules. • Redundant switched Ethernet out-of-band channels (EOBCs): Cisco NX-OS can make complete use of redundant EOBCs for communication amongst command and I/O module processors. • Network-dependent availability: Community convergence is optimized by supplying applications and functions to make equally failover and fallback clear and rapid. For instance, Cisco NX-OS offers Spanning Tree Protocol enhancements this kind of as Bridge Protocol Knowledge Device (BPDU) guard, loop guard, root guard, BPDU filters, and bridge assurance to aid assure the well being of the Spanning Tree Protocol manage plane Unidirectional Backlink Detection (UDLD) Protocol NSF graceful restart of routing protocols millisecond timers for Initially-Hop Resiliency Protocol (FHRP) Shortest-Route Very first (SPF) optimizations this kind of as backlink-state advertisement (LSA) pacing and incremental SPF IEEE 802.3ad weblink aggregation with adjustable timers and Bidirectional Forwarding Detection (BFD). Serviceability • Troubleshooting and diagnostics: Cisco NX-OS is built with exclusive serviceability functions to help network operators to take early action centered on community developments and activities, maximizing network organizing and bettering network functions heart (NOC) and vendor reaction times. Intelligent Contact Residence, Cisco Generic Online Diagnostics (GOLD), and Cisco Embedded Celebration Supervisor (EEM) are some of the characteristics that enhance the serviceability of Cisco NX-OS. • Switched Port Analyzer (SPAN): The SPAN function will allow an administrator to analyze all website traffic amongst ports (named the SPAN source ports) by nonintrusively directing the SPAN session visitors to a SPAN spot port that has an exterior analyzer connected 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 incorporates a designed-in packet analyzer to monitor and troubleshoot manage- and data-aircraft site visitors. The packet analyzer is centered on the well-known Wireshark open up resource network protocol analyzer. • Sensible Get in touch with Residence: The Intelligent Simply call House characteristic continually monitors components and software elements to offer email-based mostly notification of critical system occasions. A adaptable range of concept formats is offered for optimum compatibility with pager services, normal email, and XML-based automatic parsing apps. It provides inform grouping abilities and customizable place profiles. This attribute can be employed, for example, to straight page a network aid engineer, deliver an e mail message to a NOC, and employ Cisco AutoNotify expert services to right generate a instance with the Cisco Technical Guidance Middle (TAC). This attribute is a stage towards autonomous program operation, enabling networking units to inform IT when a challenge occurs and aiding assure that the challenge is acted on rapidly, minimizing time to resolution and growing method uptime. • Cisco GOLD: Cisco GOLD is a suite of diagnostic facilities to confirm that components and inner info paths are working as intended.
