This feature prevents policy churn by automatically placing switch interfaces with frequent flapping into an error-disabled state, effectively performing an automatic administrative shutdown. The feature also allows for automatically recovering these interfaces after a specified time. This feature reduces the risk of lost packets caused by continuous recomputation of DANZ Monitoring Fabric (DMF) policies due to flapping interfaces.

In DMF metadata is appended to the packets forwarded by the fabric to a tool attached to a delivery interface. This metadata is encoded primarily in the outer VLAN tag of the packets.

In DMF metadata is appended to the packets forwarded by the fabric to a tool attached to a delivery interface. This metadata is encoded primarily in the outer VLAN tag of the packets. By default (using the auto-delivery-strip feature), this outer VLAN tag is always removed on egress upon delivery to a tool. This feature introduces a choice to selectively preserve a packet's outer VLAN tag instead of either stripping all VLANs or preserving all of them.
