Explanation

When RADIUS is used as the primary authentication on Cisco APIC, setting the fallback login domain to "Local Realm" ensures that if external authentication (like RADIUS) fails or is unreachable, APIC will consult the local user database for authentication. This mechanism guarantees administrative access in case of remote authentication outages without requiring special login strings or additional configuration changes.
