What is ACI MCP?

MisCabling Protocol (MCP) detects loops from external sources (i.e., misbehaving servers, external networking equipment running STP, etc.) and will err-disable the interface on which ACI receives its own packet. When configured properly, MCP will send Layer-2 packets on every EPG with a custom MAC address.

How do you troubleshoot an ACI?

It is important to understand that you can troubleshoot ACI using different methods such as: The APIC Graphical User Inteface (GUI) The APIC Command Line Interface (CLI)…We will be focusing on the APIC Command Line Interface (CLI).

Step 1 – Connect APIC via SSH.
Step 2 – Fabric Membership.
Step 3 – Locating an EndPoint.

What is the difference between ACI and NSX?

The central difference is that VMware NSX focuses solely on virtualized networks, whereas Cisco ACI can connect physical networks as well. Cisco is, consequently, better for solutions that have to integrate physical hardware. Both Cisco ACI and VMWare NSX can automate virtualized networks.

What is an ACI fabric?

A fabric is a fancy term for how the computing, network, and software components of a data center are laid out. The ACI fabric is relatively simplistic. It employs a two-tier design made of spine and leaf switches, but very particular switches.

How do I find my IP route ACI?

Routing. show ip arp vlan xxx – display next-hop IP in ARP table (only for L3Out). show ip route vrf TENANT:VRF_NAME [PREFIX] – display routes, PREFIX is optional.

Can ACI and NSX work together?

NSX on ACI could be implemented in multiple ways depending on the workload requirements. First is a single overlay. This means ACI handles the networking while NSX provides distributed firewall functionality. This peering allows the enterprise network to access NSX-T resources through the ACI fabric.

What are the benefits of Cisco ACI?

The Benefits of Cisco ACI

Highly responsive and easy to configure.
Ease of configuration using GUI & REST API under a single dashboard.
Interoperability of physical and virtual workloads.
Integration of virtual machine monitor setup (without having to add the relevant software for hypervisors)

What is the benefit of ACI?

ACI will allow the network team to have visibility into both physical and virtual workloads on the network (with VMM integration, fabric can see VM attributes). You can also integrate Containers for microservices management. It improves the ease and speed of deployment.

How does ACI fabric work?

In a leaf-spine ACI fabric, Cisco is provisioning a native Layer 3 IP fabric that supports equal-cost multi-path (ECMP) routing between any two endpoints in the network, but uses overlay protocols, such as virtual extensible local area network (VXLAN) under the covers to allow any workload to exist anywhere in the …

What is APIC Cisco?

The Cisco Application Policy Infrastructure Controller (Cisco APIC) is the main architectural component of the Cisco ACI solution. It is the unified point of automation and management for the Cisco ACI fabric, policy enforcement, and health monitoring.

What does the MCP setting on ACI mean?

This setting refers to the amount of MCP packets that will be received by the ACI Fabric BEFORE the Loop Protection Action takes place. To verify that you have MCP enabled (via the CLI), login to a LEAF switch and run the show mcp internal info global command.

How does the miscabling protocol work in ACI?

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.

How to check for MCP in ACI fabric?
