| Description | This article describes an issue when adding an interface (port) to an existing FortiLink aggregate link gives an error. |
| Scope | FortiGate. |
| Solution |
In a production environment where FortiLink is configured as an aggregate link and required to add another link due to high-capacity requirements, an error may occur as below.
This is because a VLAN under the FortiLink is created with 802.1ad, which is called a Q-in-Q VLAN. It is required to remove this VLAN or change it temporarily to another, and it is possible to add a link to the FortiLink.
Note: VLANs with 802.1q configuration do not have this issue |
