Trunk mode not working in cisco switch

Question

I am setting up one 2960 cisco switches, i configured gi1/0/1 to be a trunk port but command not working:

switchport mode trunk

switchport trunk allowed vlan 1-10

i see this config in show run:

interface GigabitEthernet1/0/1

switchport trunk allowed vlan 1-10

switchport mode trunk

but interface working in vlan 1 & i see this status in show interface g1/0/1 trunk:

Port        Mode             Encapsulation  Status        Native vlan
Gi1/0/1     on               802.1q         other         1

Port        Vlans allowed on trunk

Gi1/0/1     none

Port        Vlans allowed and active in management domain
Gi1/0/1     none

Port        Vlans in spanning tree forwarding state and not pruned
Gi1/0/1     none

Answer 1

The problem was with the cable, if your cable is damaged, your trunk port configuration will remain in vlan 1 and will not work.
