Remote port mirroring to an IP address (using GRE) with ToS and DSCP

You use port mirroring to send traffic to applications that analyze traffic to monitor compliance, enforce policies, detect intrusions, and so on. you can configure remote port mirroring to send sampled packets to a remote IP address. You send the packets using GRE. You can set type-of-service (ToS) and DiffServ code point (DSCP) values to provide the necessary priorities in the network for these packets. You can also apply policing to sampled packets that are leaving the interface where the GRE destination was learned. Configure the settings you need in the [edit forwarding-options port-mirroring instance instance-name output] hierarchy.
