In-Band and Out-of-Band Management Access
The mgmt tenant provides a convenient means to configure access to fabric management functions. While fabric management functions are accessible through the APIC, they can also be accessed directly through in-band and out-of-band network policies.
Static and Dynamic Management Access
APIC supports both static and dynamic management access. For simple deployments where users manage the IP addresses of a few leaf and spine switches, configuring static in-band and out-of-band management connectivity is simpler. For more complex deployments, where you might have a large number of leaf and spine switches that require managing many IP addresses, static management access is not recommended. For detailed information about static management access, see Cisco APIC and Static Management Access.
