Ansible Automation for Nexus Dashboard/Nexus Dashboard Orchestrator

I am writing this article to make you aware of Ansible usage with Cisco Nexus Dashboard/Nexus Dashboard Orchestrator.  I will write one for Terraform with NDO soon. Previously, I had written an article  Getting Started: Cisco MSO with Ansible which is still valid for the most part. However, a few things changed from then to … More Ansible Automation for Nexus Dashboard/Nexus Dashboard Orchestrator

Subscribing Nexus Dashboard Insights Kafka Producer to a Kafka topic and streaming events to a Kafka Consumer

Applications frequently need to talk to other applications.  As an example Application A gathers some data and Application B needs to do some custom processing with the output of data from Application A.  When Applications that are split in functionality need to exchange data between each other, there are generally 2 kinds of ways to … More Subscribing Nexus Dashboard Insights Kafka Producer to a Kafka topic and streaming events to a Kafka Consumer

CPOC Series: ACI Service Chaining using Policy Based Redirect (PBR) for east-to-west traffic through an ASA FW

In this video we explore using Policy Based Redirects to identify either a subset or ALL traffic between EPGs and forcing that traffic to an external device, in our case, an ASA FW. In our case, our ACI Fabric is the L3GW for all traffic. With the PBR feature, we are going to use an … More CPOC Series: ACI Service Chaining using Policy Based Redirect (PBR) for east-to-west traffic through an ASA FW

CPOC Series: ACI Segmentation Using Microsegmented EPGs (uSeg)

In this video we explore a very popular topic in Microsegmentation. To summarize, Microsegmentation inside of ACI is taking devices inside of an EPG, and placing them inside of their own “sub-EPG”. This new EPG behaves exactly like normal EPGs from a connectivity perspective; we still need contracts to talk to other EPGs (including our … More CPOC Series: ACI Segmentation Using Microsegmented EPGs (uSeg)

CPOC Series: Segmentation in ACI using Isolated EPGs

In this video, we take a look at Isolated EPGs. By default, endpoints within the same endpoint group are free to communicate with each. However, there are use-cases where you might want to group a common set of devices, allow them to communicate to an restricted set of services, but not allow them to communicate … More CPOC Series: Segmentation in ACI using Isolated EPGs

Logging ACL/Contract Permits and Denies with ACI

Did you know that you can enable logging for permitted and denied traffic that flows through your ACI Fabric? While this feature is not meant as a replacement for Tetration or Netflow, this can be a great tool for troubleshooting and examining traffic that is flowing through applications that reside in your ACI Fabric. In … More Logging ACL/Contract Permits and Denies with ACI
