able of carrying double-tagged traffic. A trunk port is always connected to another trunk 
port on a different switch. Switching shall be performed between trunk ports and tunnels 
ports and between different trunk ports. 
 
8.1.8.1 
Double Tagging Operation 
Step 1 
If there is no SPVLAN Tag on received packet, SPVLAN Tag is added. 
SPVLAN Tag = TPID : Configured TPID 
VID : PVID of input port 
Step 2 
If received packet is tagged with CVLAN, the switch transmits it to uplink port changing to 
SPVLAN + CVLAN. When TPID value of received packet is same with TPID of port, it 
recognizes as SPVLAN, and if not as CVLAN. 
Step 3 
If Egress port is Access port (Access port is configured as Untagged), remove SPVLAN. If 
egress port is uplink port, transmit as it is. 
Step 4 
The hiD 6615 S223/S323 switch has 0x8100 TPID value as default and other values are 
used as hexadecimal number.
