Part 13: Creating MCP Interface Policy on ACI APIC

Creating MCP Interface Policy on ACI APIC

Today we are going to talk about the how to Create MCP Interface Policy on Cisco ACI APIC Dashboard. As you guys knew that APIC is a UCS based CIMC controller and we can check MCP Interface Policy on Cisco ACI APIC Dashboard.

What is Cisco ACI APIC?
One of the important pillar of Cisco ACI is APIC which is known as Cisco Application Policy Infrastructure Controller. It is single pane of glass for automation and management for the Cisco ACI fabric, policy enforcement, and health monitoring. It also optimizes performance and manages and operates a scalable multitenant Cisco ACI fabric.

Mis-cabling Protocol (MCP)
The Mis-cabling Protocol (MCP) is designed to handle misconfigurations that Link Layer Discovery Protocol (LLDP) and Spanning Tree Protocol (STP) are unable to detect. It has a Layer 2 packet that it uses to disable ports that form a loop within the fabric.

The untagged MCP packet is sent, and if the fabric sees that the packet comes back in, then the fabric knows that there is a loop and the fabric takes action based on that event. Faults and events are generated when this happens.

By default, MCP is disabled globally and enabled on each port. MCP must be enabled both globally and at the interface level in order to be active.

To create a new MCP Interface Policy follow below steps

Step 1: Login to your APIC and On the menu bar, choose Fabric > Access Policies

Step 2: In the Navigation pane, choose Policies > Interface 

Step 3: Right-click MCP Interface and select Create Mis-cabling Protocol Interface Policy

Step 4:In the Create Port Channel Policy dialog box

Perform the following actions:

  • Define a name to your policy and provide description
  • For the Admin State, choose Enable/Disable as per the requirement
