Cisco Nexus Dashboard Orchestrator (NDO) provides consistent network and policy orchestration, scalability, and disaster recovery across multiple data centers through a single pane of glass while allowing the data center to go wherever the data is. NDO allows you to interconnect separate Cisco Application Centric Infrastructure (Cisco ACI) sites, Cisco Cloud ACI sites, and Cisco…

Visibility, troubleshooting, root-cause analysis, and remediation of network issues are common challenges for day-to-day network operations. With the legacy networking operation tools, these tasks are manual, time consuming, and reactive. They require network operators to have years of experience, extensive domain expertise, and the ability to correlate different events in complex IT environments to prevent…
The Switched Port Analyzer (SPAN) feature, which is sometimes called port mirroring or port monitoring, is a method wherein a device sends a copy of all network packets seen on one port (or an entire VLAN) to another port. This allows the copied network to be analyzed for monitoring, troubleshooting, and other purposes. Figure 6-9…
The demand for data regarding network state, whether to detect hotspots in the network or to aid decision-making on workload placement, requires data at a pace that traditional methods just cannot deliver. SNMP, CLI, and syslog have limitations that restrict automation and scale. SNMP polling can often be on the order of 5–10 minutes; CLIs…
