In this tutorial we will be going over how to configure In-Band management for APIC and fabric switches. In this tutorial specifically we will be overviewing the necessary configuration where endpoints outside of ACI (via an L3Out) need to access the APIC, leaves, and spines using their In-Band Management IPs. Prerequisites:* Fabric Discovery Completed* Understanding […]

In this tutorial we’ll be going over DNS configuration for your ACI fabric. Prerequisites: * Fabric discovery completed * In-Band/Out-of-Band connectivity for your APIC(s) and fabric switches to your DNS server * Static node management addresses configured for your APICs and fabric switches under the default mgmt tenant My other tutorial Configuring Out-of-Band Management Connectivity in ACI will assist […]

In this tutorial we’ll be going over NTP configuration for your ACI fabric so that APICs and fabric switches can have their time synced properly. Prerequisites: * Fabric discovery completed * In-Band/Out-of-Band connectivity for your APIC(s) and fabric switches to your NTP server * In-Band/Out-of-Band contracts configured (need to allow default NTP port UDP 123) […]

In this tutorial we’ll be going over FEX configuration for ACI switches using the APIC GUI. Refer to the below document which overviews the ACI supported FEX models: https://www.cisco.com/c/dam/en/us/td/docs/switches/datacenter/nexus9000/hw/interoperability/fexmatrix/fextables.html#9300ACI Prerequisites: * Fabric discovery completed * Have a general understanding of ACI Access Policies My Setup: * Running ACI version 4.0(3d) * Topology: Leaf-101 eth1/5 and […]

In this tutorial we’ll be going over breakout interface configuration for ACI switches using the APIC GUI. You can refer to the following public Cisco documentation for which highlights limitations of breakout interfaces: Cisco APIC Layer 2 Networking Configuration Guide – Configuration of Dynamic Breakout Ports Prerequisites: * Fabric discovery completed * Have a general […]

In this tutorial I will be going over the necessary SNMP configuration for both APIC and fabric switches. This tutorial will only cover the necessary configuration for pulling (snmpget, snmpwalk) SNMP information and will not cover configuration of setting up SNMP traps in ACI. However, most of the configuration in this tutorial is necessary for […]

In this tutorial we will be going over the process for generating and installing custom SSL certificates for use in your ACI fabric. Prerequisites: * Fabric discovery completed * Have all Certificate Authority servers configured for certificate generation * Verify that the time on your APICs is current and correct. If the time of your […]

In this tutorial we will be going over TACACS configuration so that users can login to APICs and fabric switches with TACACS credentials. For this tutorial I will be using ACS 5.8 and ISE 2.0 as the TACACS server to authenticate against. Note: All ACS and ISE configuration in this tutorial is built from the […]

In this tutorial we will be going over how to configure Out-of-Band management for APICs and fabric switches. Functions such as querying the APIC and fabric switches via SNMP will not work unless Out-of-Band management IP addresses are configured. Prerequisites: * Fabric discovery completed * Physical Out-of-Band connectivity to your APIC(s) and fabric switches * […]
