We have a couple of nodes in our ACI fabric (Spine-1, Leaf-1, and Leaf-2). These switches will inherit the policies we create, and these policies will be pushed down to them by the APIC. Unlike traditional networking, we will rarely need to connect to them on a day-to-day basis; however, from time to time, we will need to connect to them through SSH. Being the proactive people we are, we should also make sure that we can monitor them. To do this, we will need them to have out-of-band IP addresses.

How to do it...

  1. Navigate to Tenants | mgmt | Node Management Addresses.

  5. Select the OOB management EPG (default) and enter the starting IP address and subnet mask in CIDR format (192.168.1.81/24).
  6. Enter the IPv6 addresses (if required).
  7. Do the same for the in-band addresses, creating the management EPG if...
