Configuring S3148P

Hi good morning,

 

I have a Dell s3148p switch, the version of the operating system is 9.11, the commands for more updated versions to configure a giga port in trunk mode were:

 

interface Gi1/1
no shutdown
switchport mode trunk
switchport trunk allowed vlan 10, 11
switchport trunk native vlan 10
exit

 

But with this version 9.11 these commands don't work

 

Could you please tell me if you have a manual for these commands or where I could find them?  I'm looking on the Dell's page but I can't find it
