3

Configure the GigaSMART operation and assign it to the GigaSMART group.
1. (missing or bad snippet)GigaSMART Operations (GSOP) > GigaSMART Operations.
2. Click New.
3. Type gsfvue in the Alias field.
4. Select gsg1 from the GigaSMART Groups list.
5. Select Flow Sampling from the GigaSMART Operations (GSOP) list.
6. Select Flow Sampling - IP
7. Click Save.

4

Create an ingress (first level) map.

Note:  In the rule, 2152 is GTP-u traffic.
1. (missing or bad snippet) from Traffic and select Maps > Maps > Maps.
2. Click New.
3. Configure the map.
o Enter to tool in the Alias field.
o Select Regular for Type.
o Select By Rule for Subtype.
o Select the network port for the Source.
o Select a tool port for the Destination.

4. Add a rule.
a. Click Add a Rule.
b. Select Pass.
c. Select Port Destination.
d. Enter 2152 for the port value.
5. Click Save.

FlowVUE can be used to reduce traffic to the monitoring tools. By combining FlowVUE with other GigaSMART applications such as APF, the traffic can be further reduced by filtering on specific Layer 4 application ports.

The following example samples on a subset of subscribers and forwards only the HTTP traffic related to the sampled subscriber set of devices.
