Aggregate interface Down in Passive Firewall

[Ahmedaz]

Hello Engineers.

I have this Fortinet configuration with HA active-passive mode, and an aggregate was configured with port3 and port4 on the Fortinet side BUT Now only the port4 is UP ( port3 is down because there is no cable connected yet).

And in each Huawei Switch that is in stack mode are configured Eth-trunk with LACP with 2 ports (1/0/10 and 0/0/10), connected to FortiGate's

TO Clarify it :

FG01--> PORT 4-->TO-OOB-SW-01-->PORT 0/0/10

FG02-->PORT 4-->TO-OOB-SW-02-->PORT 1/0/10

The LACP on the Switch side always shows up, BUT on the FortiGate side, it always shows us down the LACP in the Passive Firewall when I run a (( diag net aggr name Lacp_TO-OOB )) the status is down,

BUT the active one is always up.

any help ?

Thanks ...

Hello @Ahmedaz ,

As I mentioned on the other topic this is normal. You can review this topic. This is the same as your question.
