Scope FortiGate.
Solution

Under special circumstances, once an upgrade to higher speed interfaces in a LACP on NP7 device is done, the Interface Bandwidth Widget of a LACP ends up with 0bps Bandwidth output.

 

The screenshot shows when the upgrade of the interfaces in the LACP was done:

The symptoms only exist in the GUI, as the traffic will flow without any impact. This issue causes the NP7 counters to reset, which can be fixed with a reboot or an upgrade to the upcoming firmwares v7.4.10, v7.6.5 and v8.0.0. All the NP7 devices on the versions 7.4.9, 7.6.4 or earlier are affected.
