HMM can trigger auto-configuration profile Instantiation via three methods:
•
802.1q packets (Any non-IP packet)
•
VDP
•
CLI
By default, leaf switches are configured for dynamic profiles instantiation. Both dot1Q tagged and VDP protocols use
dynamic profiles based on queries to ADBM service.

3.2 Dot1q Profile Instantiation
Host facing ports will utilize dot1q tagged frames in order to drive auto-configuration profile instantiation. In this ex-
ample a host with MAC 0000.000c.00bb sends a dot1Q tagged frame, tagged with VLAN 100, to interface Ethernet
1/15 on a DFA leaf switch. The HMM process receives the frame via In-band Packet Manager, L2 network stack, and
determines if no existing profile for VLAN 100 exists locally on the DFA leaf. HMM then queries ADBM service to
search for a matching profile. Finally, HMM receives the auto-configuration profile and creates a VLAN to begin learn-
ing hosts within the new segment. The associated SVI (or BDI in case of Nexus 7000/7700) and VRF are also created
