On an 802.1q trunk link all vlans are tagged with a vlan ID except for the native vlan which is sent without a vlan ID.

The reason for the native vlan is to provide backwards compatability with older switches that do not understand 802.1q.

Hi Rupesh is correct,

Just an addition,

for some reason

If you want, you could make any vlan as native VLAN by issuing eg. native vlan 5

I think you meant to say that Jon is correct...:-)

Thats right dear,

another thing native vlan will be default to vlan 1 unless otherwise specified by command
