Refer to the diagnostic output: Two entries in the exhibit show that the same MAC address has been used in two different VLANs. Which MAC address is shown in the above output?
A.
It is a MAC address of FortiLink interface on FortiGate.
B.
It is a MAC address of a switch that accepts multiple VLANs.
C.
It is a MAC address of an upstream FortiSwitch.
D.
It is a MAC address of FortiGate in HA configuration.
La interfaz que interconecta el switch remoto y local tienen el puerto en modo TRUNK configurada con varias VLANs. Por lo tanto, se espera la dirección MAC de la interfaz en trunk se asocie con todas las VLAN incluidas. Es un comportamiento normal en switching

he exhibit shows the ISL to a VM Fortigate; C is not correct. Because it is the same link with the same MAC address, D is not correct; A is kind of tricky. Because it is a FortiLink indeed, but if we delete the VLANs, we will not have the scenario, and still we will have FortiLink, so A is not correct. B is the correct answer is the behavior of Fortilink configure for multiple VLANs.
Here is an example from my lab.
FG-01 # diagnose switch-controller switch-info mac-table | grep 84:39:8f:90:be:b2
MAC: 84:39:8f:90:be:b2 VLAN: 25 Trunk: GT80FTK23008790(trunk-id 0)
MAC: 84:39:8f:90:be:b2 VLAN: 10 Trunk: GT80FTK23008790(trunk-id 0)
MAC: 84:39:8f:90:be:b2 VLAN: 4094 Trunk: GT80FTK23008790(trunk-id 0)
La interfaz que interconecta el switch remoto y local tienen el puerto en modo TRUNK configurada con varias VLANs. Por lo tanto, se espera la dirección MAC de la interfaz en trunk se asocie con todas las VLAN incluidas. Es un comportamiento normal en switching
