Which option is required by atomic counters to be leveraged in troubleshooting endpoint connectivity?
Click on the arrows to vote for the correct answer
A. B. C. D. E.A.
Atomic counters are used for troubleshooting endpoint connectivity issues in Cisco ACI fabric. Atomic counters are a collection of counters that represent the number of packets that are processed by specific stages of the network pipeline. These counters provide detailed information about the packet flow and can help identify the point of failure in the network.
To leverage atomic counters in troubleshooting endpoint connectivity issues, the endpoints must meet specific requirements. Among the options provided, the correct answer is E. Endpoints must connect to the same leaf switch.
Explanation:
In the Cisco ACI fabric, the leaf switch is responsible for forwarding traffic to the endpoint. Each leaf switch has a set of atomic counters that provide details about the packet flow. These counters can be used to troubleshoot endpoint connectivity issues.
When two endpoints connect to the same leaf switch, atomic counters can be used to compare the counters of both endpoints. If one endpoint is receiving traffic, but the other endpoint is not, it could indicate a problem with the endpoint that is not receiving traffic. By comparing the atomic counters, it can be determined where the packets are being dropped, and the issue can be resolved.
If endpoints are connected to different leaf switches, it can be more challenging to troubleshoot connectivity issues using atomic counters. Each leaf switch has its own set of atomic counters, and comparing the counters between two switches can be difficult. Additionally, if the issue is related to the configuration of the fabric, comparing atomic counters between switches may not provide enough information to determine the root cause of the problem.
Therefore, option E is the correct answer. Endpoints must connect to the same leaf switch to leverage atomic counters in troubleshooting endpoint connectivity issues.
