Hi,

You do not need to create "interface vlan x" but you should create vlans instead, ie:

vlan 10

exit

vlan 20

exit

vlan 30

exit

vlan 40

exit

copy run start

I would expect that you configure trunk port only towards FW, the rest may perhaps be configured as access ports. With your configuration (range & trunk, ie. all trunks) all the devices connected can operate within vlan 10 only if they do not support tagging.

Best regards,

Antonin
