Double Tagging Operation
Step 1
If there is no S-VLAN Tag on the received packet, S-VLAN Tag is added.
S-VLAN Tag = TPID : Configured TPID
VID : PVID of input port
Step 2
If a received packet is tagged with C-VLAN, the switch transmits it to uplink port changing
to S-VLAN + C-VLAN. When the TPID value of received packet is same with the port
TPID, it is recognized as S-VLAN, and if not, it is recognized as C-VLAN.
Step 3
If Egress port is Access port (configured as Untagged), remove S-VLAN. If egress port is
uplink port, transmit as it is.
Step 4
The V8102 switch has the 0x8100 TPID value as default and other values are used as
hexadecimal number.
