Examples

Example 1: In the first example, we configured the global MCP policy, enabling MCP globally but only on the native VLAN (per_vlan). If a loop is detected within the default timers, the port will be disabled (action). A key cisco has been configured to send out the MCP PDU, and it is validated upon receipt to ensure the loop is detected within the same fabric.

apic:
  access_policies:
    mcp:
      admin_state: true
      per_vlan: false
      action: true
      key: cisco

Example 2: In this example, we have configured the global MCP policy, whereby MCP is enabled globally and per VLAN (per_vlan). Every 5 seconds, an MCP PDU will be transmitted over the enabled interface, which will wait for 180 seconds (initial_delay) after the initial interface activation before sending out an MCP PDU every 5 seconds (frequency_sec). If the MCP PDU is received 3 times ( frequency_sec), the port will be disabled. A key, cisco, has been configured to transmit the MCP PDU and is validated upon receipt to ensure that the loop is detected within the same fabric.
