How set a "Forbidden VLAN" for a port in a M4300 ?

I want to setup a new port ( 1/0/40 ) exactly the same as 1/0/37 ( circled in red ). But I can't figure out how to the "Forbidden VLAN" was originally set for port 37.

    In interface config mode

     

    vlan participation exclude 

     

    See the CLI manual for the M4300, M4250/M4350, ...

     

    vlan participation

    This command configures the degree of participation for a specific interface or range of interfaces in a VLAN. The number is a valid VLAN identification number in the range 1-4093, and the interface is a valid interface number.
    Format vlan participation {exclude | include | auto} number
