| Description | This article describes how to avoid misconfiguration of VLANs on trunk interfaces via GUI. |
| Scope | FortiSwitch in Standalone mode. |
| Solution |
In some scenarios, switches have multiple trunk interfaces. Let's say for example PO1 and PO6, and both the trunk interfaces will have different sets of VLANs:
edit "PO6"
set allowed-vlans 23-24,26-27,29-31,34-35,40,45-54,56-57,59-60,62,67-70,72-74,79-80,84,86-87,89,91,93-94,96-98,100-106,151,153-154,157-158,161-168,173,176,800,811
set snmp-index 74
next
edit "PO1"
set allowed-vlans 10-12,18-19,21-24,26-31,34-37,40,45-60,62,67-70,72-77,79-81,84,86-87,89-91,93-94,96-98,100-106,141-142,150-158,161,166,168,173,176,207,800,811
set snmp-index 69
next
in GUI, when both the interfaces are selected and add a new VLAN (For Ex: 22 ) as below:
In this way Vlan-config of PO6 is overridden by the config of PO1, as seen in the below screenshot:
Therefore, while configuring VLANs on trunk interfaces, make sure that each trunk interface should be selected individually and then add VLANs.
Selecting multiple trunk interfaces for adding VLAN is only supported when all the selected trunk interfaces have an identical set of VLANs configured.
