Is it possible to use CISCO CLI in OpenWRT?

I would prefer to use CISCO commands to create a VLAN for example.

rooter# vlan 30
rooter # name IOT
rooter# interface eth3
rooter(config-if)# switchport mode access vlan 30

to create VLAN 30 on eth3

Thank you in advance

Please post output of

ubus call system board

Script it ?

No, OpenWrt does not support CISCO commands. The equivalent are UCI commands, but quite different to CISCO's. Or someone could perhaps make a translator, but I have no idea of how much work that would entitle...
