If I assign a native VLAN access port at the edge for a given set of nodes,
and the header remains there
Will it get treated as VLAN 10 and not Native VLAN as it moves upstream?
I read about using this tactic on a Junos guide page ~ I'm not sure if engineers use this. I haven't read of a Native VLAN tag field in headers, so if this is the case, I'm wondering if this strategy is actually used.

Hi
Native vlan is use in Trunk mode when you dont want to tag one specific vlan. Need to check in all switch model but I am pretty sure that port in access mode does not have the option of native vlan in cisco switches.

Host-Access-SW1-trunk-SW2
Host send frame UN-TAG
SW1 check the config of interface "access VLAN X" and forward frame according to VLAN X
SW1 -SW2 agree the native VLAN is VLAN X
SW1 forward traffic through the tunnel UN-TAG since it native vlan for both SW.
