Create Prefiltering Policy Template

GigaVUE-FM allows you to create a prefiltering policy template with a single rule or multiple rules. You can configure a rule with a single filter or multiple filters. Each monitoring session can have a maximum of 16 rules.

To create a prefiltering policy template, do the following steps:

1. Go to Resources > Prefiltering, and then click UCT-V.

2. Click New.

3. Enter the name of the template in the Template Name field.

4. Enter the name of a rule in the Rule Name field.

5. Click any one of the following options:

■   Pass — Passes the traffic.
■   Drop — Drops the traffic.

Note:  In the absence of a prefilter rule, traffic is implicitly allowed. However, once rules are defined, they include an implicit drop rule. Should the traffic not conform to any of the specified rules, it will be dropped.

 

6. Click any one of the following options as per the requirement:

■   Bi-Directional —- Allows the traffic in both directions of the flow. A single Bi-direction rule should consist of 1 Ingress and 1 Egress rule.
■   Ingress — Filters the traffic that flows in.
■   Egress — Filters the traffic that flows out.

7. Select the value of the priority based on which the rules must be prioritized for filtering. Select the value as 1 to pass or drop a rule in top priority. Similarly, you can select the value as 2, 3, 4 to 8, where 8 can be used for setting a rule with the least priority. Drop rules are added based on the priority and, then pass rules are added.

8. Select the Filter Type from the following options:

■   L3
■   L4

9. Select the Filter Name from the following options:

■   ip4Src
■   ip4Dst
■   ip6Src
