ASAv Service Graph – Cloud Orchestrator Package

Introduction Introduced in ACI 3.1, the Cloud Orchestrator¬†Package greatly simplifies the configuration of Service Graphs. Intended for use with an Orchestrator such as Microsoft Azure for a generic configuration of any L4-L7 device. Prerequisites ACI 3.1 Supported Device Package Supported L4-L7 Device BD Configuration to match the Service Insertion configuration Since this is routed mode … More ASAv Service Graph – Cloud Orchestrator Package

Using MCP (MisCabling Protocol) for 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. 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

Using Serial-over-Lan (SOL) on the CIMC to access the APIC (instead of KVM console)

The CIMC is Cisco’s answer to lights-out management for UCS servers, including the UCS servers that house the APICs. For troubleshooting the APIC, most engineers assume you must have direct console (i.e., physical access) or use the Java (or later HTTP)-based KVM Console to get true OOB access to your APIC, however, this is not … More Using Serial-over-Lan (SOL) on the CIMC to access the APIC (instead of KVM console)

Configuration to affect HealthScore with CRC errors

HealthScores are a good way to monitor faults and the general health of your ACI Fabric. But in certain cases, such as CRC errors, if the interface does not change state (up/down), no fault will be generated and consequently the HealthScore is not affected. In this article we examine what steps are necessary to ensure … More Configuration to affect HealthScore with CRC errors

Creating a backup for your APIC Cluster

One of the main advantages that ACI offers is the ability to simplify the configuration, and the ability to backup, your entire datacenter configuration. In a traditional datacenter network, backups must occur on a box-by-box basis (leading to configuration sprawl), and the process to back them up is generally managed by a combination of network … More Creating a backup for your APIC Cluster

Using the auto-provision feature to automatically upgrade new switches added to your ACI Fabric

After a brief break from the APIC, the auto-provisioning feature is available (again) inside of the APIC GUI starting with APIC version 2.3 release and later. However, if you need it (or want it) and you are running at least APIC 2.2, you can configure the feature via API (i.e., XML or JSON). Why would … More Using the auto-provision feature to automatically upgrade new switches added to your ACI Fabric

ACI: Using Postman to quickly configure interface policies

Postman can be used to push configuration to the APIC via the Restful interface quicker than what can be accomplished if we did the same configuration via the GUI. In this article, we will provide XML-based configuration snippets which will allow you to authenticate with the APIC (via Postman), and then will allow you to … More ACI: Using Postman to quickly configure interface policies
