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.

8.1.8.1Double 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.

8.1.8.2Double Tagging Configuration

Step 1

Designate the QinQ port.

Command	Mode	Description
vlan dot1q-tunnel enable PORTS	Bridge	Configures a qinq port.
		PORTS: selects port number qinq to be enabled

Step 2

Configure the same PVID with the VLAN of peer network on the designated qinq port.

Command	Mode	Description
		Configures a qinq port.
vlan pvid PORTS <1-4094>	Bridge	PORTS: selects port number qinq to be enabled
		<1-4094>: VLAN ID
To disable double tagging, use the following command

Command		Mode	Description
vlan dot1q-tunnel	disable	Bridge	Configures a qinq port.
PORTS			PORTS: a port qinq to be disabled
