Unable to connect 92D on a Juniper switch - MAC learning issue

[seth57]

Hi all

i just bought a 92D to replace my 60D

I converted config file to match new hardware and connected it to Juniper switch but nothing worked

I searched what could be wrong on fortigate but all seems to be OK

On switch side, i saw that when internal1 was connected ( only this port connected to the switch ), MAC address was correctly learnt on the switch port but when internal2 was connected, MAC of internal1 disappeard from the switch and i could only see the MAC of internal2

At this instant, my 60D is working perfectly on this switch so i think that the problem does not come from the switch

are you aware about this kind of problem ?

Is there any parameter to set up ?

Thanks in advance

Hello

Sorry for delay, i was not able to perform tests

I can see now that the MAC of the cisco switch is learned by the juniper switch via Fortigate interfaces ...

I will try to find out what can be the command to solve this

So do you have the FGT92D connected directly to the EX or thru a cisco switch?

[seth57]

Cisco switch is connected to wan1 and all other interfaces to EXswitch

Cisco and EX are connected but MAC address of the cisco switch is learnt via FGT ...
