The native VLAN is the VLAN that is used if the interface is to become a Layer 2 interface. If you do not explicitly define a native VLAN, VLAN 1 becomes the native VLAN by default. Be aware that an IEEE 802.1Q header is not added when data are sent on the native VLAN. Ensure that the trunk ports on both of the connected devices have the same native VLAN. A mismatch in native VLANs can cause inter-VLAN routing issues, among other problems
As per your error NATIVE_VLAN_MISMATCH: NATIVE VLAN MISMATCH DISCOVERED ON FASTETHERNET0/10 (6), WITH OUTSTATION FASTETHERNET0/15 (4)."
