This is a more complex example of GTP engine grouping than the previous example. This example has four engine ports on two GigaSMART line cards on the same GigaVUE‑HC3 node. The GigaSMART line cards are in slots 1 and 3.

The GigaVUE‑HC3 node is the cluster leader of a two-node out-of-band cluster. A GigaVUE‑HC1 is the standby node in the cluster.

This example includes GigaSMART operations for GTP flow filtering with load balancing, GTP flow sampling with load balancing, and GTP whitelisting. The forward list must be associated with the GigaSMART group on the leader, the GigaVUE‑HC3.
