Hi Haseeb,
The native vlan is not for configuring trunkports.The trunk ports are the part of all vlans.Native vlan frames will not tag any
vlan information when it pass through the trunk ports.all other frames will be tagged when passing through the trunk port.u can change native vlan from vlan one to any other vlans (default native is vlan1).native vlan also u can use as data vlan like other vlans.
rate if helpfull
