Short overview about Cisco Aci Troubleshooting and what's good to know about.
If you’re a network engineer who has been tasked with troubleshooting a Cisco ACI deployment, this article is for you. We’ll cover the basics of ACI troubleshooting and some common issues you may encounter.
ACI consists of three main components: the Application Policy Infrastructure Controller (APIC), the leaf and spine switches, and the endpoint devices. The APIC is the central point of management and policy enforcement for the ACI fabric. The leaf and spine switches make up the ACI fabric itself, and the endpoint devices are the devices that are connected to the leaf and spine switches.
Now that we’ve reviewed the basics of ACI, let’s take a look at some common troubleshooting scenarios.
One common issue you may encounter is that traffic is not flowing as expected between two endpoint devices. This can be caused by a number of factors, such as incorrect policy configuration, misconfigured switch ports, or physical connectivity issues.
If you suspect that the issue is due to incorrect policy configuration, the first thing you should do is check the APIC for any policy violations. To do this, login to the APIC and navigate to the “Policy Violations” section. Here you will see a list of any policy violations that have occurred. If you see a policy violation for the traffic that is not flowing as expected, you can investigate further to determine the cause of the policy violation.
Another common issue is that an endpoint device is not receiving an IP address from the DHCP server. This can be caused by a number of factors, such as incorrect DHCP server configuration, misconfigured switch ports, or physical connectivity issues.
If you suspect that the issue is due to incorrect DHCP server configuration, the first thing you should do is check the DHCP server for any errors. To do this, login to the DHCP server and navigate to the “Logs” section. Here you will see a list of any errors that have occurred. If you see an error for the endpoint device that is not receiving an IP address, you can investigate further to determine the cause of the error.
If you’re still having trouble troubleshooting your Cisco ACI deployment, there are a number of resources available to you. Cisco provides a comprehensive ACI documentation website, which includes troubleshooting guides and best practices. In addition, the Cisco Support Community is a great place to ask questions and get help from other Cisco customers.
