GigaSMART GTP Whitelisting and GTP Flow Sampling Examples
Refer to the following examples:
Example 1: GTP Whitelisting
Example 1 is a GTP whitelisting configuration example. Traffic from network ports go to the three first level maps (GTP-Control, GTP-User, and Fragments-Not_First) and then to the virtual port (vport1). If there is a match to an IMSI in the whitelist (MyIMSIs), it is forwarded to a port.

Example 2: GTP Whitelisting with Multiple Maps
Example 2 is a GTP whitelisting configuration example that includes multiple GTP whitelisting maps, which provide a more granular selection of tool ports.
Traffic from network ports go to the three first level maps (GTP-Control, GTP-User, and Fragments-Not-First) and then to the virtual port (vport1). Two whitelist maps are configured. The first map specifies a rule for version 1 traffic. The second map specifies a rule for version 2 traffic.

Example 3: GTP Flow Sampling
Example 3 is a GTP flow sampling configuration example. Traffic from network ports go to the three first level maps (GTP-Control, GTP-User, and Fragments-Not_First) and then to the virtual port (vport1). The traffic flow is sampled based on the rules in one flow sampling map (GTP-Sample-01). The flow sampling rules specify IMSI, IMEI, and MSISDN numbers, as well as the percentage to sample. Packets are then accepted or rejected. Accepted packets are forwarded to a port. Rejected packets are dropped. Packets that do not match a rule will be passed to subsequent maps.

Example 4: GTP Whitelisting, GTP Flow Sampling, and Load Balancing
Example 4 combines the GTP whitelisting configuration from Example 1 with the GTP flow sampling configuration from Example 3, and adds GigaSMART load balancing.
In Example 4, traffic from network ports go to the three first level maps (GTP-Control, GTP-User, and Fragments-Not-First) and then to the virtual port (vport1). If there is a match to an IMSI in the whitelist (MyIMSIs), it is forwarded to the port group (PG-Whitelist) for load balancing.
Note: In Example 4, the tool ports in the port group are on the same node as the GigaSMART group and GigaSMART operation.
If there is not a match to an IMSI in the whitelist, the traffic flow is sampled based on the rules in the flow sampling map (GTP-Sample-01). The flow sampling rules specify IMSI, IMEI, and MSISDN numbers, as well as the percentage to sample. Packets are then accepted or rejected. Accepted packets are forwarded to the port group (PG-Sample) for load balancing. Rejected packets are dropped. Packets that do not match a rule will be passed to subsequent maps.

Example 5: GTP Flow Sampling with Multiple Maps
Example 5 includes multiple GTP flow sampling maps, which provide a more granular selection of tool ports for flow sampling.
In Example 5, traffic from network ports go to the three first level maps (GTP-Control, GTP-User, and Fragments-Not_First) and then to the virtual port (vport1). If there is a match to an IMSI in the whitelist (VoLTE_1MM), it is forwarded to the port-group (PG-Whitelist-1) for load balancing.
Note: In Example 5, the tool ports in the port group are on the same node as the GigaSMART group and GigaSMART operation.
If there is not a match to an IMSI in the whitelist, the traffic flow is sampled based on the rules in the four flow sampling maps (GTP-Sample-1 to GTP-Sample-4).
The flow sampling rules in each map specify IMSI, IMEI, and MSISDN numbers, as well as the percentage to sample. Packets are then accepted or rejected. Accepted packets are forwarded to the port-group (PG-Sample-1 to PG-Sample-4) for load balancing. Rejected packets are dropped. Packets that do not match a rule will be passed to subsequent maps, in this example, to a shared collector.

Example 6: APN for GTP Whitlelisting, GTP Flow Sampling
Example 7 specifies APN patterns for GTP whitelisting and GTP flow sampling.
In Example 7, traffic from network ports go to the two first level maps (gtp_to_v1_c and gtp_to_v1_u) and then to the virtual port (v1).
In the whitelist map, if there is a match to the APN pattern and if the IMSI is present in the whitelist (IMSI), packets are forwarded to a tool port.
If there is not a match to an IMSI in the whitelist, the traffic is flow sampled based on the APN pattern in the flow sampling map. Accepted packets are forwarded to the same tool port as specified in the whitelist map.
Any unmatched traffic goes to a shared collector that sends it to a different tool port.
