Auto-sense Logical Flowcharts
The system uses a per-interface state to adapt to all Auto-sense events. Each state transition determines background configuration on the port. The system does not display Auto-sense port configurations in the show running-config command or in the saved configuration file; instead use the show auto-sense commands to show global and port specific Auto-sense information..
The following flowcharts describe the system logic for Auto-sense port state detection, how the system configurations change the logic path, and the Auto-sense configuration results.
Note
The vlan create CLI command examples do not apply to DvR leaf switch configurations. DvR leaf switches create VLANs automatically.Auto-sense Fabric NNI
Detection of a Fabric network-to-network interface (NNI) results in tagged Backbone VLAN IDs (B-VID) with IS-IS NNI enabled.
Auto-sense UNI Client without NAC
Detection of a user-to-network interface (UNI) client without network access control (NAC) results in untagged data configuration based on system configuration.
Auto-sense UNI Client with NAC
Detection of a user-to-network interface (UNI) client with network access control (NAC) results in untagged, tagged, or dropped data configuration based on system configuration.
Auto-sense Voice without NAC
Detection of voice without network access control (NAC) results in untagged, tagged, or dropped data based on system configuration.
Auto-sense Voice with NAC
Detection of voice with network access control (NAC) results in untagged, tagged, or dropped data based on system configuration.
Auto-sense FA Proxy Switch
Detection of a Fabric Attach (FA) proxy switch results in untagged or tagged data based on system configuration.
Auto-sense FA Ring Proxy Switch
Detection of Fabric Attach (FA) ring proxy switch results in untagged or tagged data based on system configuration.
Auto-sense FA WAP, Camera, or OVS without NAC
Detection of a Fabric Attach (FA) wireless access point (WAP), camera, or open virtual switch (OVS) without network access control (NAC) results in untagged or tagged data based on system configuration.
Auto-sense FA WAP, Camera, or OVS with NAC
Detection of a Fabric Attach (FA) wireless access point (WAP), camera, or open virtual switch (OVS) with network access control (NAC) results in untagged or tagged data based on system configuration.
Automatic Channelization with Auto-sense
The switch automatically channelizes a port if the port operates in Auto-sense mode and you insert a supported part. The following images show the impact of Auto-sense on a channelization-capable port.
For more information, see Channelization.
Auto-sense with ExtremeCloud SD-WAN
Detection of an SD-WAN Appliance results in untagged VLAN 4047 and the application of Fabric Extend tunnel assignments. If you use SD-WAN Orchestrator to enable a Local Breakout (LBO) branch, Auto-sense can also apply the LBO configuration to select VRFs.
