Links between Sensor and Active Fail-Open module Mon0/Mon1 are up but the Sensor is not receiving any traffic from the Active Fail-Open module. When this occurs, the BYP/TAP/DISC LED is Amber and INLINE LED is OFF.
You can troubleshoot the issue using the following two methods:
- At the CLI, run the following commands:
- get_hb_act_mode - If HB active mode is off, enter the next command.
- get_bypass_mode - If Active state is bypass, enter the next command.
- set_hb_act_mode on
- From the web interface:
- Check if the
Active State is in
Inline or
Bypass or
Tap.

- Check if the Appl State is unknown. This means that the module in forced bypass state.
- In the
Bypass page, confirm that
HB active mode is set to
ON.

- Check if the
Active State is in
Inline or
Bypass or
Tap.
