One  request regarding 802.1q native vlan............

.Suppose we have two switches A and B with native VLAN ID configured to 100 on both switches and we have few users connected to VLAN 1 and few users connected to VLAN 10 on a switch A with trunk link connected to another switch B.

  If a user from VLAN 10 in switch A sends data to a member in same VLAN 10 in switch B, then trunk adds a VLAN ID tag to the frame sent from switch A to B, then switch will identify respective VLAN and forwards accordingly.

If a user from VLAN 1 in switch A wants to send data to a user in VLAN 1 in switch B  --- is traffic sent as VLAN 1 traffic by attaching vlan id tag and not as native vlan traffic or vlan 1 traffic is considered as native vlan traffic (native vlan is set as 100) that is untagged traffic.

  if vlan 1 traffic is considered as native vlan traffic then will it add native vlan ID of 100 to vlan 1 traffic?

Thanks...................
