Hi,
There is some missing information as VLAN 41 is for data or voice? If it voice then your switch configuration must be as:
Interface range gig1/0/1-20
switchport mode access
switchport access vlan 1
switchport voice vlan 41
spanningtree portfast
If VLAN 41 is not a voice VLAN then your configuration as like:
interface range gig 1/0/1-20
switchport mode trunk
switchport trunk allowed vlan 1,41
switch tunk native vlan 1
