QuestionQ51

ACI Fabric Infrastructure

An engineer needs to connect a new host to port 1/1 on Leaf 101. A Cisco ACI fabric has an MCP policy configured but is experiencing excessive Layer 2 loops. The engineer wants the Cisco ACI fabric to detect and prevent Layer 2 loops in the fabric. Which set of actions achieves these goals?

Explanation

Cisco ACI Mis-cabling Protocol (MCP) detects a loop when an MCP packet returns to the fabric and can disable the affected port. MCP must be enabled globally regardless of the per-interface configuration. The per-interface MCP policy is applied through an interface policy group, allowing it to protect the host-facing port.
