# RADIUS-Based Packet Mirroring Dynamically Created Secure Policies

RADIUS-based packet mirroring uses dynamically created secure policies, which are based on the RADIUS VSAs that an authorized RADIUS administrator creates. A policy is created when the packet mirroring action is initiated at the RADIUS server, and then applied to the interface that is dynamically created for the user. When the mirroring operation is disabled, the secure policy is deleted.

The E Series router creates a name for the dynamically created policies—the name consists of the string spl followed by a hexadecimal integer, such as spl_88000008. The name is displayed by the show secure policy-list command.
