Technical Tip: The correct approach to automatically create the FortiLink trunk with the correct member ports
| Description | This article describes how to form FortiLink trunks automatically and to avoid flapping of trunks. |
| Scope | FortiSwitches managed by FortiLink. |
| Solution | The FortiLink ISL/ICL link between two switches creates trunks on each switch automatically with respective member ports. The lldp-profile on peer ports should be default-auto-isl, for example: config switch physical-port edit "port10" set lldp-profile "default-auto-isl" next end If there will be any need to add the extra link then this new port should not be added manually to the trunk. The port will be recognized and added to the trunk by the switch. Refer to the below diagram:
Adding the member ports manually can cause trunk flapping or packet loss in the link. |
