Switch Latency Monitoring Overview
The switch latency monitoring feature marks each ingress and egress packet with a timestamp value. To calculate the latency for each packet in the system the switch compares the ingress with the egress timestamp. The feature allows you to display historical latency averages between all pairs of ports, as well as real-time latency data.
You can use the latency measurements to identify which flows are impacted by latency issues. In addition the statistics generated by the switch latency monitoring feature allow you to plan network topologies, manage incident responses and identify root causes for application issues in the network. You can also use the statistics to provide a Service Level Agreement (SLA) for latency intensive applications.
