An interface down, will enter bypass mode?

Hi, engineers, the device is equipped with a hardware bypass card. When a certain interface of the bypass card is down, will the device enter bypass mode?

You are probably referring to Fail-Open NIC. It goes to fail-open mode when there is a power or software failure of the appliance. If one of ports on the card itself is down, fail-open is not activated.

Yes, it is fail-open NIC. There is a user's hardware bypass card with only two interfaces. When these two interfaces are down, the device will enter bypass mode.So I want to ask, when an interface is down, will it enter bypass mode?According to your reply, an interface down, the device will not enter bypass mode

I think you misunderstand the purpose of FO NIC. It is to maintain connectivity in case of appliance failure. It short-cuts the network cables, allowing two ports to be connected directly, when the appliance where FO NIC is installed is down because of any failure. 

Here is quite from https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut...

 

The appliance enters Bypass Mode, if one of the following occurs:

  1. There is a power loss.
  2. The appliance is rebooting.
  3. The appliance is overloaded. It enters Bypass Mode for at least 1 minute.
  4. There is a system failure. It enters Bypass Mode for at least 5 minutes.
  5. The appliance stops responding for 60 seconds.

From what you are showing, it is the other way around. First, the card goes into bypass, then one of the interfaces goes down.
