> # Configuring Traffic-Mirror Actions (C-Web Interface)

> Use this action to mirror traffic from a destination to a source or from a source to a destination. You can configure traffic-mirror actions for JUNOS filter input policy rules.

> Before you use traffic-mirror actions, you must configure forwarding options on JUNOS routing platforms for port mirroring and next-hop group. For information about how these features work on the router, see the JUNOS Policy Framework Configuration Guide.

> The rule containing a traffic-mirror action must comply with these conditions:

> - It must be combined with forward actions in the same rule. One of the forward actions must accept the traffic if the source and/or destination IP addresses do not match the conditions.
> - It contains either no classify-traffic condition or only one classify-traffic condition.
> - It can be marked for accounting.

> To configure a traffic-mirror action:

> 1. In the side pane, select a JUNOS filter policy rule.
> 2. From the Create new list, select Traffic Mirror. Type a name for the action, and click OK.
> 3. Enter information as described in the Help text in the main pane, and click Apply.
