Prefiltering

Prefiltering allows you to filter the traffic at UCT-Vs before sending it to the GigaVUE V Series Nodes.

Create a Prefiltering policy template

In GigaVUE‑FM, you can create a prefiltering policy template that includes rules and filter values.

• You can apply the template to multiple monitoring sessions.

• A monitoring session can use only one template at a time.

• You can define a maximum of 16 rules in a monitoring session.

Editing a Monitoring Session

While editing a session, you can modify the policy template with required rules and filter values. These changes apply only to that session. GigaVUE‑FM does not save these changes to the template.

Guidelines for prefiltering in Next Generation UCT-Vs are:

• Prefiltering is supported on Next Generation UCT-Vs. It is not available in the classic mirroring mechanism.

• Both Linux and Windows UCT-Vs support Prefiltering.

• A monitoring session supports only one prefiltering policy. All agents in the session use the same policy.

• If multiple monitoring sessions share the same agent, and if one session does not use prefiltering, the system disables prefiltering. It applies a PassAll policy instead and forwards all traffic without filtering.
