|Description||This article describes that FortiLink p2p is not working over the Cambium Networks antenna.|
Fortiswitches are using LLDP to negotiate a LAG interface (ISL trunk) in the interconnection between them.
When there is a P2P interconnection, it is necessary to add the command 'set fortilink-p2p enable' on the interfaces connected to the antennas, to change the LLDP destination MAC address to the broadcast MAC address to bypass middle layer-2 devices:
However, some antennas, even after applying this command, still answer the LLDP packets to Fortiswitches, preventing the LAG interface from being formed. This is the case of some Cambium Networks antenna
