This chapter contains the following sections:
Management Connectivity Workflows
Describes the prerequisites and high-level workflows for configuring in-band or out-of-band management connectivity to switches in the ACI fabric.
Management Access in Cisco ACI
Describes in-band and out-of-band management connectivity for the APIC and the ACI fabric, including interface-selection and external-profile behavior.
Export Policies for Technical Support, Statistics, and Core Files
Describes how Cisco APIC export policies transfer operational and diagnostic data to external hosts for troubleshooting and analysis.
Configuration backup and recovery
Configuration backups enable you to restore Cisco APIC to a known-good configuration state and protect secure properties in exported configuration files.
Controller Configuration Backup, Restore, and Rollback
Describes the features for creating configuration snapshots, restoring saved configurations, and returning controller configuration to a previous state.
Using the APIC troubleshooting tools
introduces the tools and methodology commonly used to troubleshoot problems. These tools can assist you with monitoring traffic, debugging, and detecting issues such as traffic drops, misrouting, blocked paths, and uplink failures.
Using Atomic Counters
Describes the use of atomic counters in a system. Provides context for when and why atomic counters are used to ensure accurate counting in concurrent environments.
Enabling and viewing digital optical monitoring statistics
Describes how to enable and view real-time digital optical monitoring (DOM) statistics for SFPs, SFP+, and XFPs, including transmit bias current, transmit power, receive power, and power supply voltage data compared against threshold values.
Viewing and understanding health scores
Describes how the APIC uses a policy model to generate aggregated health scores for infrastructure, applications, and services, enabling isolation of performance issues through network hierarchy drilling.
Enabling port tracking for uplink failure detection
Explains how to enable port tracking for uplink failure detection using the GUI, NX-OS CLI, and REST API to monitor network connectivity and automatically respond to link failures.
SNMP
Describes the Simple Network Management Protocol (SNMP) support in ACI.
Configure the SNMP policy using the GUI
Configures and enables an SNMP policy on Cisco ACI-mode switches using the GUI, including prerequisites, policy creation, and assignment to a pod policy group.
Configure an SNMP trap destination using the GUI
Configures an SNMP trap destination in the GUI so that an SNMP manager can receive trap notifications from the fabric.
Configure an SNMP trap source using the GUI
Configures an SNMP trap source in the GUI so that a monitoring policy can generate SNMP trap notifications.
Monitor the system using SNMP
Describes how SNMP clients retrieve CPU and memory usage data from APIC and other nodes so that you can monitor system health and identify performance issues.
Using SPAN
Describes how to configure and use Switched Port Analyzer (SPAN) to mirror network traffic from source ports to destination ports for monitoring and troubleshooting purposes.
Using statistics
Describes how Cisco APIC uses configurable statistics policies to gather real-time and historical data from various network objects for monitoring, trend analysis, and automated fault detection.
About Syslog
Describes how syslog messages are generated and delivered in Cisco ACI systems. Provides context for monitoring faults, events, and user actions through system log messages for troubleshooting and auditing.
About Traceroute
Describes how traceroute enables users to discover the actual network path packets take to their destination. Provides insight into connectivity and troubleshooting by revealing hop-by-hop details and identifying points of failure.
Using the troubleshooting wizard
Describes how the Troubleshooting Wizard helps visualize and understand network behavior to diagnose issues like intermittent packet loss between endpoints during specific time frames.
Checking for configuration synchronization issues
Verify configuration synchronization status in Cisco Application Centric Infrastructure by checking for pending transactions that may affect system performance.
User activities
Explains the feature that allows administrators to view a 2-week history of actions performed by users in Cisco APIC.
Embedded logic analyzer module
Describes an engineering tool that enables analysis of packet forwarding within Cisco ASICs.
acidiag Command
Use the acidiag command to troubleshoot operations on the Cisco APIC.
