Example: Using DTCP Messages to Trigger, Verify, and Disable Traffic Mirroring for Subscribers

This example shows how to create DTCP messages to do the following:

Trigger traffic mirroring for two subscribers based on interface ID.
Trigger a drop policy if one does not already exist.
Remove an existing drop policy.
Verify that subscriber traffic on the two interfaces is being mirrored.
Disable traffic mirroring on the two subscriber interfaces.
Verify that traffic mirroring was stopped on the two subscriber interfaces.

In this example, SSH is being used to communicate with the router.

Creating DTCP ADD Messages to Trigger Traffic Mirroring

This section shows examples of DTCP ADD messages on a mediation device that use the interface ID to trigger traffic mirroring on interfaces demux0.30010002 and demux0.30010001.

Creating DTCP ENABLE Messages to Trigger Traffic Mirroring

This section shows an example of DTCP ENABLE messages on a mediation device that use the interface ID to trigger traffic mirroring on interfaces demux0.30010002 and demux0.30010001.

Creating DTCP DISABLE Messages to Trigger Traffic Mirroring

This section shows examples of DTCP DISABLE messages on a mediation device that use the interface ID to trigger traffic mirroring on interfaces demux0.30010002 and demux0.30010001. Whether you used DTCP ADD plus a policy or DTCP ADD and DTCP ENABLE, you can turn the policy off with DTCP DISABLE.

Using LIST Messages to Verify That Subscriber Traffic Is Being Mirrored

This section shows examples of a LIST message on the mediation device. The LIST message requests information about the subscribers being mirrored. The information is returned in a LIST response. The response shows that traffic for the two interfaces—demux0.30010002 and demux0.30010001—is being mirrored.

Using DELETE Messages to Remove Traffic Mirroring Triggers

This section shows examples of DELETE messages used to remove traffic mirroring triggers on demux0.30010001 and demux0.30010002. DTCP DELETE can use either Criteria-ID to delete only that criteria or Cdest-ID to delete everything with cdest-ID that you previously created.
