ACI is different. I know, this may come as a shock to any CCIE or Network Engineer who may have wondered into the APIC GUI to configure an interface, only to be met with terms like, “Physical Domain”, or “AAEP”. But, it is different, and different, I would argue, for more good than bad. And, … More ACI Fabric Access Policies for CCIEs
Configuring Out-of-Band connectivity to your ACI Fabric devices is a critical component to successfully maintaining and operating your datacenter. When it comes to configuring OOB connectivity to your devices (Leafs, Spines, and APIC Controllers), you’ll have need to do two things to get things going: All devices will need static OOB addresses (APIC Controllers, Leafs, … More ACI: Configuring Out-of-Band (OOB) access for your Fabric
Prerequisites Make sure and have the appropriate Contracts configured for OOB to permit the access to the desired port. If you do not have this in place, the traffic destined to the new port will be killed by the contracts. While not a prerequisite, Since HTTPs access via the GUI is generally the “front … More Changing the default port for HTTP(s) access to the APIC GUI

MisCabling Protocol (or MCP) detects loops from external sources (i.e., misbehaving servers, external networking equipment running STP) and will err-disable the interface on which ACI receives its own packet. Enabling this feature is a best practice and it should be enabled globally and on all interfaces, regardless of the end device. MCP limits the blast … More Using MCP (MisCabling Protocol) for ACI
