Description

This article describes the reason for the following error when a managed FortiSwitch shows a sync error:

 

"error_reason":"unable to find 'xxx' in table 'switch.vlan."

Scope FortiGate and managed FortiSwitch version 6.x and above.
Solution

Sometimes, it is possible to encounter an issue where the configuration from FortiGate is not pushed to the managed FortiSwitches.

 

There could be multiple reasons for this issue.

 

This article will explain why this particular error appears:

 

"error_reason":"unable to find 'xxx' in table 'switch.vlan."

 

When the command 'execute switch-controller get-conn-status' is executed, the switch shows the 'E' flag.

 

Moreover, when the command 'execute switch-controller get-sync-status switch-id <switch-id>' is executed, the following error will appear:

 

"error_reason":"unable to find 'xxx' in table 'switch.vlan."

 

This error appears when IGMP snooping is enabled on a higher number of VLANs than the switch supports.

 

Refer to the section of this document where it states 'On the FS-100E series, IGMP snooping can be enabled on a maximum of 6 VLANs'.

 

The same limit applies for 100F models as well. For example, 148F.
