redirect interface

Function

The redirect interface command configures an action of redirecting packets to an interface in a traffic behavior.

The undo redirect command deletes the redirection configuration.

By default, no action of redirecting packets to an interface is configured in a traffic behavior.

Format

undo redirect

Tunnel interfaces do not support forced.

Usage Guidelines

Usage Scenario

The redirect interface command configures an action of redirecting packets to an interface in a traffic behavior. For example, packets can be redirected to a firewall for security check.

Follow-up Procedure

Run the traffic policy command to create a traffic policy and run the classifier behavior command in the traffic policy view to bind the traffic classifier to the traffic behavior containing redirection to an interface.

Precautions

The traffic policy that contains the redirection action can only be applied to the system, an interface, or a VLAN in the inbound direction.

The device supports only redirection to Layer 2 physical interfaces and Eth-Trunk interfaces.

The packets that are redirected to an interface will be discarded if the VLAN of the packets on the interface is not allowed.

Example

# Redirect packets to GE0/0/1 in the traffic behavior b1.

<HUAWEI> system-view
[HUAWEI] traffic behavior b1
[HUAWEI-behavior-b1] redirect interface gigabitethernet 0/0/1
