The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.
The Reverse Flow Metadata Support feature creates reverse metadata flow sessions to act as proxy and signal metadata, and support QoS for the reverse session. The reverse sessions are created using the attributes of the forward session.
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release.

End devices provisioned with metadata producers such as Media Services Interface (MSI), Media Services Proxy (MSP), and Network Based Application Recognition (NBAR) add flows to metadata database. When an end device cannot signal metadata, a reverse metadata flow session is created to act as a proxy and signal metadata, and support QoS for the reverse session. The reverse sessions are created using the attributes of a forward session. The reverse flow session is enabled only on the device, which is connected to the endpoint and cannot signal metadata. That is when the device is not provisioned with a metadata producer such as MSP, MSI or NBAR.

The following example shows how to enable reverse flow of metadata information in Global configuration mode:
Device> enable Device# configure terminal Device(config)# metadata flow Device(config)# metadata flow reverse transmit Device(config)# exit
The following example shows how to enable reverse flow of metadata information in Interface configuration mode:
Device> enable Device# configure terminal Device(config)# metadata flow Device(config)# interface Ethernet 0/1 Device(config-if)# metadata flow reverse transmit Device(config)# exit
