Simplify network monitoring with Cisco Nexus Dashboard Data Broker

[ad_1] As we speak’s information facilities depend on a wide range of instruments to offer enhanced visibility and observability of essential utility site visitors and site visitors circulate particulars. Using switch-based telemetry capabilities is an especially in style method, but it surely’s typically the case that packet particulars or granular site visitors filtering are desired; thus, a complementary resolution is required. Cisco Nexus Dashboard Knowledge Dealer is the right resolution to ingest Switched Port Analyzer (SPAN) and/or Take a look at Entry Level (TAP) site visitors, apply filters and header modifications, present packet deduplication, after which redirect site visitors to monitoring and different instruments akin to intrusion prevention techniques (IPS) and safety incident and occasion administration (SIEM) options.

Answer structure The Nexus Dashboard Knowledge Dealer features a centralized administration graphical person interface (GUI), deployed right this moment on a number of Linux hosts for top availability, with a plan for assist on unified Nexus Dashboard. It makes use of Cisco Nexus 9000 Collection Switches, which require the cost-effective information dealer license (NX-OS Necessities), to unlock this performance. For scale-out necessities, a number of SPAN/TAP vacation spot switches could be aggregated right into a single topology. This topology is managed by the centralized information dealer resolution, which directs site visitors to an information dealer change (see Determine 1) for distribution to the specified instruments in your atmosphere.

Determine 1. Pattern Knowledge Dealer structure For switches that assist Nexus Dashboard Knowledge Dealer, any interface can be utilized in your manufacturing community connection ports in addition to your connections to the required instruments (any port, any performance). Interface speeds from 1 Gbps to 400 Gbps are supported, making certain enough bandwidth and connectivity choices in your packet brokering wants, which meet right this moment’s demanding information middle progress.

Low-touch configuration Figuring out and configuring the specified site visitors units and vacation spot interfaces is an underlying core requirement of the Knowledge Dealer deployment. Knowledge Dealer helps routinely configure each your information middle and campus units, whatever the existence of a centralized controller. Knowledge Dealer natively integrates with Cisco Utility Centric Infrastructure (ACI) information middle materials, Cisco Catalyst Heart-based campus materials, in addition to standalone Nexus and Catalyst switches. This eliminates the handbook configuration burden, making certain correct resolution configuration and fast turn-up. The operational good thing about solely requiring a single GUI for deploying the required change configuration enhances the simplicity of a Knowledge Dealer deployment.

Clients who require packet brokering for each information middle and campus environments can relaxation assured that the only Knowledge Dealer interface will simplify the required configurations for his or her heterogeneous environments.

Resiliency and redundancy Counting on Knowledge Dealer for always-on packet visibility is a actuality with the mechanisms included for making certain most resolution uptime:

The assorted service nodes and information dealer switches that make up the answer topology are tracked by Knowledge Dealer and, equally essential, are bypassed if Knowledge Dealer detects both a service node challenge or packet dealer change interface challenge. Knowledge Dealer helps symmetric hashing and load-balancing, permitting for the distribution of site visitors throughout a number of cases of a particular instrument. If there is a matter with the aggregation change, Knowledge Dealer can routinely program a backup path to make sure that the specified site visitors continues to be captured. Knowledge Dealer incorporates a fail-safe mechanism, permitting for direct communication between ingress and egress interfaces within the occasion of a service node failure.

The above options be sure that any failures throughout the topology are addressed dynamically, requiring no human intervention and offering most uptime for steady visibility and observability.

Packet deduplication Gathering SPAN and/or TAP from a number of sources yields the chance of duplicate site visitors being acquired by the Knowledge Dealer switches. The deduplication characteristic, supporting each Transmission Management Protocol (TCP) and Person Datagram Protocol (UDP), was added in NX-OS 10.4(1)F, permitting for streamlined packet dealer deployment. The deduplication perform could be carried out in-line on the Knowledge Dealer change(es) or out-of-line by a number of devoted Knowledge Dealer switches. An essential attribute is that the deduplication perform is hardware-accelerated, guaranteeing constant resolution efficiency and scalability.

A further side of deduplication is the power to right-size instruments to accommodate the quantity of post-deduplication site visitors, versus redundant, duplicated site visitors.

Visibility of encapsulated site visitors Packet brokering instruments are sometimes deployed in environments which have a number of packet encapsulation applied sciences, for instance, multi-protocol label switching (MPLS), digital extensible LAN (VXLAN), and generic routing encapsulation (GRE). An efficient instrument wants to have the ability to view the precise endpoint-to-endpoint site visitors throughout the encapsulated packets, thus packet-header and label-stripping capabilities are essential. Knowledge Dealer permits for header and label stripping for the aforementioned applied sciences, along with Q-in-Q and Cisco Encapsulated Distant Switched Port Analyzer (ERSPAN) site visitors, offering best-in-class visibility in your information middle, campus, and edge site visitors.

This has the additional advantage of much less processing required by evaluation instruments within the atmosphere, leading to bandwidth and value financial savings.

NetFlow technology Evaluation instruments have the aptitude of processing SPAN and TAP site visitors redirected from Knowledge Dealer, however there are quite a few instruments, akin to Splunk, that profit from receiving both NetFlow or sFlow particulars for the specified site visitors. Knowledge Dealer can generate both NetFlow or sFlow related to SPAN or TAP site visitors, permitting for compatibility with a larger vary of instruments. Coupled with the deduplication characteristic, you might be assured of streamlined, environment friendly circulate visibility along with packet visibility in your information middle and different site visitors in your community.

Cisco Nexus Dashboard The Cisco Nexus Dashboard has advanced to include centralized NX-OS cloth administration, proactive day-2 operations, and cloth orchestration in a simplified, intuitive GUI. The upcoming Nexus Dashboard 4.2 launch will incorporate Knowledge Dealer, finalizing the simplified administration and operational method for any Cisco cloth kind. Clients preferring a separate Linux-based Knowledge Dealer deployment will proceed to have that choice.

Step into the way forward for site visitors evaluation Attaining complete site visitors visibility with out overwhelming your evaluation instruments is the core promise of Cisco Nexus Dashboard Knowledge Dealer. By delivering a single, clever platform, it simplifies operations with a unified view of your information middle and campus, lowers complete value of possession by hardware-powered deduplication, and ensures uptime with built-in, automated resiliency. This ensures your monitoring instruments get the precise information they want—and nothing they don’t.
