OOB & In-Band Management

OOB & In-Band Management

Out of Band Management

In ACI, with the help of RJ45 Management ports on APIC, OOB connectivity is provided. These APIC OOB Ports will be connected to any OOB management network with 10/100/1000BASE-T connectivity options.

OOB management address can either be statically assigned to fabric nodes, or let APIC assign the IP address dynamically from Management Subnet.

Below are the steps which is required to configure OOB Management from APIC.

Create Static Management Address:

Go to Tenants | mgmt. | Node Management Addresses | Static Node Management Address | Right click to create State Node Management Address

Configure below parameters on this section

  • Node Range: 101-101
