Troubleshooting Wizard-Enables administrators to troubleshoot issues that occur during specific time frames, which can be designated by selecting. Traceroute-Enables you to find the routes that packets actually take when traveling to their destination. The format can also be displayed in NX-OS CLI format. Syslog-Enables you to specify the minimum severity level of messages to be sent, the items to be included in the syslog messages,Īnd the syslog destination. Viewing statistics enable you to perform trend analysis and troubleshooting. Statistics-Provides real-time measures of observed objects. SPAN-Switchport Analizer (SPAN) enables you to perform detailed troubleshooting or to take a sample of traffic from a particularĪpplication host for proactive monitoring and analysis. SNMP-Simple Network Management Protocol (SNMP) enables you to remotely monitor individual hosts (APIC or another host) and find. Port Tracking-Enables you to monitor the status of links between leaf switches and spine switches for detecting uplink failure. Health Scores-Enables you to isolate performance issues by drilling down through the network hierarchy to isolate faults to specific managed. Digital Optical Monitoring-Enables you to view digital optical monitoring (DOM) statistics about a physical interface. Quick debugging and isolation of application connectivity issues. Atomic Counters-Enables you to gather statistics about traffic between flows for detecting drops and misrouting in the fabric and for enabling. Packets or flows dropped because of taboo contract deny rules. ACL Contract Permit and Deny Logs-Enables the logging of packets or flows that were allowed to be sent because of contract permit rules and the logging of. See the tools listed below for a summary overview of the tools described in this chapter: These toolsĬan assist you with monitoring traffic, debugging, and detecting issues such as traffic drops, misrouting, blocked paths,Īnd uplink failures.
