There is no standard heartbeat port across all Sensor models. Instead, the port or ports you use to connect the two Sensors for failover depends directly on the model at hand. The details are as follows:
| NS-series Sensor model | Port used for heartbeat connection |
|---|---|
| NS9500 | G0/1 |
| NS9300 | G1/1 and G1/2 |
| NS9200 | G0/1 |
| NS9100 | G0/1 |
| NS7500 | G0/1 |
| NS7350 | G0/1 |
| NS7250 | G0/1 |
| NS7150 | G0/1 |
| NS7300 | G0/1 |
| NS7200 | G0/1 |
| NS7100 | G0/1 |
| NS5200 | G1/1 and G1/2 |
| NS5100 | G1/1 and G1/2 |
| NS3200/NS3100 | 1 |
Note
High availability is not supported in NS3500 Sensor model.
