Never had anyone ask for that before.

See the following ref, a dot1q tag is 4 bytes

the first 2 should be 0x8100

the next 4 bits are related to layer 2 qos,

the last 12 bits are the VLANID (VLAN #).

You might have to ask what the requestor really needs.

Hi.

Am I then the first? We go there!

How I can see this value in the switch? What's the command?

Thanks.
