- Under normal operating conditions, traffic from the Vlan3410 flows through E2 between both Netonix devices.
Example: Ping from 192.168.10.1 to 192.168.10.2
- Under conditions of connection failure in E2, traffic from the Vlan3410 flows through E3 between both Netonix devices.

Fail A:
- Under normal conditions, traffic from 192.168.10.1 to 192.168.10.2 flows through E2.
- Action: Break the connection between E3, wait 1 second, then resume the connection between E3.
- Failure: Traffic between 192.168.10.1 and 192.168.10.2 stops flowing.
Failure B:
- Under normal conditions, traffic from 192.168.11.1 to 192.168.11.2 flows through E3.
- Action: Break the connection between E2, wait 1 second, then resume the connection between E2.
- Failure: Traffic between 192.168.11.1 and 192.168.11.2 stops flowing.
