LABEL DESCRIPTION

VLAN Stacking

Active Select this to enable VLAN stacking on the Switch.

SP TPID SP TPID is a standard Ethernet type code identifying the frame

and indicates whether the frame carries IEEE 802.1Q tag

information. Choose 0x8100 or 0x9100 from the drop-down list

box or select Others and then enter a four-digit hexadecimal

number from 0x0000 to 0xFFFF. 0x denotes a hexadecimal

number. It does not have to be typed in the Others text field.

Port The port number identifies the port you are configuring.

Role Select Access to have the Switch add the SP TPID tag to all

incoming frames received on this port. Select Access Port for

ingress ports at the edge of the service provider's network.

Select Tunnel (available for Gigabit ports only) for egress ports

at the edge of the service provider's network.

In order to support VLAN stacking on a port, the port must be

able to allow frames of 1526 Bytes (1522 Bytes + 4 Bytes for the

second tag) to pass through it.

SPVID SPVID is the service provider’s VLAN ID (the outer VLAN tag).

Enter the service provider ID (from 1 to 4094) for frames

received on this port.

Priority On the Switch, configure priority level of inner IEEE 802.1Q tag in

the Configuration > QoS Menu > 802.1p Priority screen.

"0" is the lowest priority level and "7" is the highest.
