Although the recipes have, more often than not, been relatively painless and trouble free (the exception being configuring SNMP), we should cover some basic troubleshooting steps.
We will start from the ground up, working from layer 2 upward before we get to the APIC and then on to troubleshooting VMM domains, routing and multicast, and QoS.
Note
Because of the fast pace at which ACI is growing, the command set is also increasing. The commands listed in the following recipes are by no means the only ones available.
