The following describes a single host and a single satellite topology.
A/S uplinks can be on the same forwarding path (FP) or forwarding complex or on a different FP. An FP refers to a set of chipsets on a line card used to simultaneously forward paired upstream and downstream traffic.
Although a pair of uplinks can be active or standby for the same set of ports, both uplinks can be active for a set of different ports. For example:
| Ports | Active | Standby |
|---|---|---|
esat-1/1/u1 |
satellite ports 1-12 |
satellite ports 13-24 |
esat-1/1/u2 |
satellite ports 13-24 |
satellite ports 1-12 |
